Intel sgx remote attestation example There are two types of attestations for Intel SGX – local attestation and remote attestation. A client’s enclave can attest to a remote entity that it is The Intel SGX device plugin and related components allow workloads to use Intel SGX on platforms with SGX Flexible Launch Control enabled, e. non-revoked SGX platform. Private Forums; Intel oneAPI Toolkits Private Forums; All other private forums and groups; Intel® Connectivity Research Program (Private) Hi Scott, We are currently using SGX remote attestation via the EPID model which is about to be deprecated soon. For example, when retrieving confidential data from a sensing IoT device This sample demonstrates how to do remote attestation between two enclaves and establish a secure communication channel for exchanging secret (AES key) between them. ; adombeck/python-sgx - Python interface to the SGX SDK. 2,241 Views Mark as New; Bookmark; Subscribe; Mute; TEEs hosted on Nvidia GPU receive attestation via NVIDIA’s Remote Attestation Service (NRAS). [1] [2] SGX is designed to be useful for implementing secure remote computation, 2 Attestation Service for Intel® SGX Attestation Service for Intel® SGX (IAS) is a web service hosted and operated by Intel in a cloud (for example, planned and unplanned downtimes, limited availability alerts) as well as updates related to I'm designing remote attestation. This paper explains the Intel SGX Platform Services implemented with the CSME. cpp:122. The code requires the installation of Intel SGX here and the SGX driver here. Also, the party that's want to verify a quote needs to be registered as service provider (short SP) to the IAS. 3 Intel® SGX Instructions The Intel® SGX Architecture [1] provides the hardware instructions, EREPORT and EGETKEY, to support attestation and sealing. I'll now start with a high level overview of the typical of the remote attestation procedure: Intel Software Guard Extensions (SGX) remote attestation enables enclaves to authenticate hardware inside which they run, and attest the integrity of their enclave memory to the remote party. The quote is generated by the sgx_ra_proc_msg2() (actually a library trusted function sgx_ra_get_msg3_trusted(). With Intel SGX remote attestation, you can trust your data is running on a platform that has the latest security updates and information about the software running in the enclave. 3. 1. Example of a remote attestation with Intel's SGX including the communication with IAS. Hi Kuppusamy, I've tried the sample code shipped with the SGX SDK. Use the vSphere Client to register your SGX-capable hosts with multiple CPU sockets with the Intel Registration Server and use remote attestation for applications running inside your vSGX Background information. A remote party should be able to verify that the right application is running inside an enclave on an Intel SGX enabled platform.

The function in Remote Attestation that does the signing is service_provider. ). h file: The application port and the SGX Remote Attestation infrastructure, online services provided by Intel and/or third parties (see DCAP); SDK and assorted software. They use SGX enclave as a hardware root of trust as Learn the basics of how Intel® Software Guard Extensions (Intel® SGX) works and how it can protect your data while it is being processed. This scenario typically arises when deploying trusted applications in a cloud environment, which provides Hi all, In my research I have to install a software that uses SGX inside of a docker container. As a particular example, an Intel SGX quote (attestation evidence) contains an attestation claim MRENCLAVE = <SHA256 hash of Intel SGX remote attestation is an important security feature that allows you to verify that your enclave is an Intel SGX enclave before you share data to it. Intel’s remote attestation service from Intel Trust Authority was built to help make this vision a reality. Fully isolated execution. when i run a SGX remote attestation example （EPID attestation mode /opt/intel/sgx-dcap-pccs# dmidecode -t bios # dmidecode 3. We've updated to the latest BIOS version from the OEM, and the latest microcode patc Intel® SGX Attestation Review Attestation is the process of demonstrating that a software executable has been properly instantiated on a platform. Intel® SGX prevents software access to keys of other Enclave Identities 1. By leveraging Intel Software Guard Extensions (Intel SGX) and Remote Attestation with Trusted Computing Base Recovery Attestation . The attestation Hardware is the Intel SGX enabled CPU. The challenger is off-platform with respect to the attester. Throughout the report we will use a running example to describe the aspects of remote attestation. 2. This TCB status provides information that helps Intel® Software Guard Extensions (Intel® SGX) Re:Remote attestation not possible, request guidance; 1451 Discussions. Support Community; About; Developer Software Forums. Do we have any sample code/example of remote attestation using the reply In short, SGX architecture is a hardware-enforced security mechanism that requires Trusted Computing Base (TCB), Hardware Secrets, Remote Attestation, Sealed Storage and Memory Encryption. This Intel-centric attestation when i run a SGX remote attestation example （EPID attestation mode /opt/intel/sgx-dcap-pccs# dmidecode -t bios # dmidecode 3. Ran PCKIDRetrievalTool or At Intel, we envision a world in which each line of code, every byte of data, and every digital interaction can be independently and seamlessly verified in real-time. The attest command collects evidence from the attester(s) and then forwards the evidence with an attestation request to Intel Trust Authority. . ; To step into the Platform Software (PSW) code or the trusted runtime functions, build and install the debug and development packages of the PSW and the There are several resources provided by Intel indicating how to perform the Remote Attestation process, including this example. The following attestation token examples were generated for their respective TEE. One way to improve scalability would be to automate the verification process, for example by sharing the attestation certificates at a central location, accessible to all relying parties. The quote generation process works as follows: Example of a remote attestation with Intel's SGX including the communication with IAS. RemoteAttestation原理介绍 1. 2 Remote Attestation Intel® Software Guard Extensions (SGX) Rebekah Leslie-Hurd Intel® Corporation January 8th, (for example, sealing key) Attestation and Sealing Overview Remote Platform Client Application Local and remote attestation capabilities are combined to enable a remote party to This section introduces the design details of the remote attestation service provided by Intel. For example, function sgx_init_ra declared in sgx_tkey_exchange. Updated: Found the correct demonstration at the official intel sgx remote attestation sample here. My problem is, the msg2 created by the SP is never accepted at the ISV app (see the logs below): Sent MSG1 to remote attestation service provider. The message exchange over the network is performed using The SPID (and its associate key) are what you use to authenticate to Intel Attestation Services (IAS) when doing EPID based SGX remote attestation. The remote attestation is the process by which a remote application verifies that the code running is truly within a secure enclave. The Trusted Execution Environment (TEE) adapters encapsulate Description. Remote attestation provides verification for three things: the application’s identity, its intactness (that it has not been tampered with), and that it is running securely within an Hi Flavio, I believe you might have confused two steps there. It starts by initiating the MessageHandler that handles the messages to be exchanged during remote Intel® SGX Attestation sample code demonstrates how to generate a quote from an SGX enclave using Open Enclave SDK and then get it validated by Microsoft Azure Attestation. For me, upgrading the bios will face a greater risk, which may cause me to reinstall the entire ubuntu system and lose files. TEE adapters. We are still trying to figure out why the Remote Attestation sample outputs the same values for msg2_gb_gx and msg2_sign_gb_ga_x. The "enclave held data" for the quote is populated It then creates an X. Other works have explored integration at levels below or above the TLS protocol layer with resulting differences in usability or generality. To en-force direct control of attestation, Intel mandates attestation to be verified by Intel’s attestation service. Hi Yu, There seems something wrong with the platform service configuration and this problem is solved after install the latest version of Intel management engine component and sgx platform service (The full ME stack needs to be installed on the system for the services to be available to SGX platform software). Intel® Software Guard Extensions Data Center Attestation Primitives (Intel® SGX DCAP) provides SGX attestation support targeted for data centers, cloud services providers , and enterprises. This is most useful for migrating existing applications to Intel Trust Authority attestation. The Intel SGX workload contacts the In this white paper we describe our approach to combine Intel SGX remote attestation seamlessly into the existing Transport Layer Security (TLS) secure channel protocol. In For Intel SGX, remote attestation only reflects the TCB level when the enclave was created. DU Distributed Unit ECDSA Elliptic curve digital signature algorithm SGX ECDSA Remote Attestation. I have seen that it is possible to compile and run SGX program inside of a SGX container with this docker image: https://hub. cpp in the RemoateAttestation project is like this: Quotes created on an Intel SGX platform can also be verified on systems that do not support SGX (e. The primary responsibility of the IAS is verification of attestation evidence (for example, planned and unplanned downtimes, limited availability alerts) as well as revocation data updates. A minimum SGX PRM is required to run the Quote Generation Service (QGS) on the host OS (or inside a \n. The sgx-ra-sample will fail attestation if run in Simulation mode. SGX PRM Size: Defines the size of the Processor Reserved Memory (PRM), which is used by Intel SGX to hold enclaves and related protected data structures. The PCE provides a mechanism to sign another enclave (for example QE) REPORT using the PCK cert private key. Determine SGX enclaves running on same system. 509 certificate with a custom extension containing this SGX quote. That report is then used to generate the quote, which represents its signature. This will make remote attestation easier to use in practice and facilitate the wider uptake of Intel SGX. The caching service for RATLS integrates remote attestation into the TLS handshake. SGX Application - Remote Attestation 1. Developer Software Forums; Software Development Tools; (Intel® SGX) Discussion board focused on hardware-based isolation and memory encryption to provide extended code protection in solutions. If you are unable to use this static library in your development environment, the source code for a sample untrusted key exchange library is included in the isv_app subfolder of the Remote Attestation sample application that is shipped with this SDK. ; apache/incubator-teaclave-sgx-sdk - Rust SGX SDK provides the ability to write Intel SGX Hi, I'm looking into the sample code shipped with the SGX windows sdk as well as the user guide document. 1 远程认证原理. Initially, the application needs service used to delegate computing tasks securely. And I'm just looking into the function reference in SGX in-depth user guide, and try to implement a simple remote attestation project just for trial. The Intel SGX claims provide the input values for token customization. Can SGX prove two enclaves are on different computers? 3. Using Intel SGX Remote Attestation in a Client-Server Architecture. However, its possible that when composed Intel SGX provides an opaque box which, if implemented correctly, prevents anyone — including the owner of the box, from looking inside. Sample tokens. The high-level flow of an Intel SGX ECDSA attestation is shown in Figure 1. The Intel® Software Guard Extensions (Intel® SGX) Remote Attestation End-to-End Example explains the purpose of the Platform Services Enclave (PSE): "The PSE is an architectural enclave included in the Intel SGX software package that supplies services for trusted time and a monotonic counter. Intel® Xeon® E3. The OS and other processes can access a debug-enabled enclave's memory and resources. The obstacle is that the intel sgx sdk doesn't fit this model. I'm wondering, how could a service pr remote attestation seamlessly with a standard secure channel. How can we implement attestation by Intel SGX? I Local (Intra-platform) attestation I a mechanism for creating a basic assertion between enclaves software-guard-extensions-remote-attestation-end-to-end-example. JesusG_Intel. As an example, Intel SGX’s remote attestation (detailed in Section3. , a code snippet of service_provider. I built an app with performing random number from ecall. It seems that I cannot put custom data into the report_data of the report body in the quote with sgx_ra_proc_msg2(). The sample "remote attestation" project is not interacting with IAS. Microcode updates can be loaded via OSPL when enclaves are present and being used, resulting in a more robust platform, but Since how the client enclave react to SigRL stored in sgx_ra_msg2 is hidden in sgx_ra_proc_msg2() function (and the sgx_ra_proc_msg2_trusted function within it), I don't know if it is really the case that the enclave will terminate when it finds out its private key is actually in the SigRL, although it seems so because this function can return 01org/linux-sgx - Intel(R) Software Guard Extensions for Linux* OS. Continue msg1 An overview of attestation policies in Intel® Trust Authority. The "enclave held data" for the quote In a remote attestation, the Intel SGX workload attests to a remote entity over a secure communication channel. (The source code of most of the functions described in the article can be found here. The Attestation Service for Intel SGX (IAS) allows a remote party to gain confidence that the intended software is securely running within an enclave on a fully If the stock Intel SDK is being used for attestation, a 32 byte (256 bit) NIST P-256 public generator key will be used in the field. Local attestation occurs between two enclaves on the same client platform and does not require access to Intel’s provisioning or attestation services. 一. Intel ® SGX sets up a confidential computing environment at the physical level to ensure data security by providing hardware-based protections instead of firmware- or software-based protections. This is Solved: Remote Attestation sample now live. 0. Intel® Software Guard Extensions (SGX) has an attestation and sealing capability that can be used to remotely provision secrets and secure secrets to an enclave. 2 Setup Intel® SGX Data Center Firstly, when attempting to make and run the Remote Attestation Sample file to perform Intel SGX Remote Attestation, I get an output similar to the attached 'RA. Example Request The Intel® Software Guard Extensions (Intel® SGX) remote attestation allows a remote party supported. Other contact methods are available here.

I installed intel sgx on my experimental physical host. The service provider's remote attestation server does not require Intel SGX hardware or software to run. The steps summarized below. As an example, Knauth et al. Figure 1: Remote Attestation Example. I've tried the sample code shipped with the SGX SDK. We envision computing you can trust, from the cloud to the edge. Intel's Confidential Computing solutions make end-to-end protection of data possible. The Attestation Report Signing CA Certificate (IASReportSigningCertificate. This protects Intel® SGX allows an enclave instance to obtain keys that are bound to the platform and the enclave. Remote attestation fails if the Intel SGX enclave that is being attested is run in Simulation mode because the enclave does not have the The SGX architecture and development that I directed implemented an enclave<->enclave communication's model where the enclaves themselves were capable of conducting remote attestation with Intel Attestation Services (IAS) or in the case of the use of Data Center Attestation Protocol (DCAP) whatever attestation service is available from the Remote attestation, an advanced feature of Intel SGX, is the process of proving an enclave is established in a secure hardware environment. How to perform it? enclave { /*. View the PCK certificates are used during remote attestation of the platform. Call sgx_create_enclave success. The code consists of two separate programs, the ServiceProvider and the Application. As silicon-rooted Trusted Execution Environment (TEE) technologies, Intel® Software Guard Extensions (Intel® SGX) and Intel® Trust Domain Extensions (Intel® TDX) offer solutions for protecting data in both applications and We are currently using SGX remote attestation via the EPID model which is about to be deprecated soon. Remote attestation provides verification for three things: So there are many clients providing secret data and a server running encalve. lib, was built for use with Visual Studio 2015. Additional information. Knauth et al. Receiving confirmation from IAS indicates that the QUOTE structure received was indeed produced inside a genuine Intel SGX enclave, now the peers still need to verify if the identity of the peer enclave is the same as During an Intel SGX remote attestation, the client’s quote is signed based on a known TCB and the relying party uses this collateral to determine whether a client is current on security patches as of a certain date, out of date, or current but running with a sub-optimal security configuration. Intel® Software Guard Extensions Data Center Attestation Primitives (Intel® SGX DCAP) provides SGX attestation support targeted for data centers, cloud services providers, and enterprises. The sample code project only demonstrated necessary steps of the remote attestation, but it did not execute all the steps in the real. (TEEs) as a promising solution to enhance security and privacy. Let's figure out why you can't run the sgx-ra Intel® Software Guard Extensions (Intel® SGX) Discussion board focused on hardware-based isolation and memory encryption to provide extended code protection in solutions.

Call enclave_init_ra success. h. Software Guard Extensions (Intel® SGX) remote attestation allows a remote party to check that the intended software is securely running within an enclave on a system with the (for example, the Intel® SGX remote attestation service). 8 for Linux* OS and Microsoft* Windows* OS on the 6th and 7th generations of Intel SGX Remote Attestation is not sufficient Yogesh Swami yogesh. In the preceding sample example, the token_fields is an output variable that will contain a set of one or more customized claims after the policy is applied, and input refers to the attestation token document. The only thing matters is the second the PSW and the SDK are collectively referred to as the Intel SGX SDK. My colleague could run SGX remote attestation sample on Intel-NUC NUC7PJYH (Pentium J5005) but not on Intel-NUC 9VXQNX (Xeon). Intel ® SGX uses instruction set extensions and an access control mechanism to isolate the runtime environment of SGX programs. The Attestation allows a remote party to gain confidence that the intended software is securely running within an enclave on a fully patched, Intel SGX enabled platform. The server in this code sample requires the Intel SGX SDK header files in order to simplify the code and build process, but this is not strictly necessary. This document details the remote attestation as implemented on BlindAI for intel SGX platforms. This customized certificate is sent to a TLS client in the TLS handshake protocol. The sample application runs SGX DCAP Quote Generation sample: The Intel SGX example uses the Intel Trust Authority client for C and the Intel SGX adapter to collect evidence from the enclave. In RemoteAttestation, the untrusted app calls the function put_secret_data to pass the data to the enclave. Moderator 02-04-2021 03:12 PM. When I look into the ra sample provided by Intel. In a real-world environment, these would be separate builds. If attestation is successful, an attestation token Hi all. For example, attestation environments that cache PCK certificates need to provide the Intel® SGX Resolution. can we run Linux commands inside sgx-enclave? 2. Remote attestation not possible, request guidance. We will describe each facet from the perspective of a small internet connected Remote attestation can be used on devices ranging from small legacy devices[4], to large com- such as Intel SGX and ARM TrustZone. then Intel is the attestation service for the device. They chose not to change or extend the Activates/deactivates Intel SGX, which is used by Intel TDX for remote attestation. Our POSSUM protocol, which we wrote specifically to support secured enclave<->enclave communication based on bilateral remote attestation, uses this field to authenticate a Curve25519 public generator key. Introduction The Intel SGX device plugin and related components allow workloads to use Intel SGX on platforms with SGX Flexible Launch Control enabled, e. Deploy the pod. Azure confidential computing offers Intel SGX-based virtual machines (VMs) for isolating a portion of your code or data. Most importantly we SGX supports quote generation not just within the remote attestation process, but also as an independent procedure. # SMBIOS implementations newer than version 3.

An Intel® SGX based attestation allows a remote party to gain confidence that the intended software is running within an enclave on an Intel® SGX enabled platform. In Intel SGX, we achieve the remote attestation by generating a enclave report. Here is also my aesmd log which seems to be also ok: And there is my certificate from this log, looks like also good: Intel Software Guard Extensions (SGX) remote attestation enables enclaves to authenticate hardware inside which they run, and attest the integrity of their enclave memory to the remote party. Trouble Creating and Executing an Intel SGX Enclave. These extensions allow an application to instantiate a protected container, referred to as an enclave. Yes, this scenario is possible with Intel SGX enclaves. Question on Remote attestation Sample Code. DU Distributed Unit ECDSA Elliptic curve digital signature algorithm The remote key exchange static library, sgx_ukey_exchange[mt]. An enclave is a architecture for remote attestation and sealing. 1 are not # fully supported by this version of dmidecode. e. Though that particular article is using Windows, the exact same openssl commands can be used in Linux to create self signed certs. to check that the intended software is securely running within data and services on a range of platforms and attestation environments. With this config remote attestation sample are working from OE, and Intel. It seems that the last step of attestation is service provider receiving and verifying MSG3 which includes the REPORT_DATA generated by the quoting enclave. lib and replay the pre-computed messages stored in sample_messages. ensuring both ends of a secure channel are attested. The client gets the SGX quote from the certificate and performs remote attestation to verify that the connected server runs inside an authentic Intel® SGX enclave. Toggle navigation. I used sgx-gdb and found that sgx_init_quote (invoked by sgx_ra_get_msg1) is returning SGX_ERROR_UNEXPECTED. g.

SMBIOS 3. The Intel SGX attestation service is a public web service operated by Intel for client-based privacy focused usages on PCs or workstations. Error, call sgx_ra_get_msg1 fail [main]. The application in this private fork uses the shared secret derived during the RA process (and thus known only to the ISV server and the remote SGX enclave, but not the rest of the untrusted remote application) to encrypt (and decrypt) data using the AES 128 bit GCM protocol on both the ISV and SGX sides. Two Ubuntu releases are currently supported for base host OS and guest OS: 8. Remote Attestation Prerequisites. The Attestation API exposed by the Intel® SGX attestation service is a programming interface for service providers to verify attestation evidence of SGX enabled enclaves. Intel® Software Guard Extensions Data Center Attestation Primitives (Intel ® SGX DCAP) provides SGX attestation support targeted for data centers, cloud services providers , and enterprises. To get a SPID/Key, you need to have/create an Intel Developer Zone (IDZ) account and then click one of the "Subscribe" buttons on that link Junli provided. The Intel Trust Authority client library handles the low-level calls to platform-specific attestation primitives for the TEE. This method supports Intel attestation via the Intel SGX platform software. Subscribe More actions. When you build with SGX enclaves, you can verify and validate that your trusted Sadly, remote attestation is not possible without the Intel Attestation Service, which I'll call IAS from now on. The certificate mentioned in this thread is used for communicating with the Intel Attestation Service (IAS) to validate a QUOTE that was generated by an SGX enclave. cpp (ISV stands for Individual Software Vendor). Thank you for your reply！ Recently, I haved checked the relevant information. to ensure that the chain of trust is unbroken and that all quoting components that gather evidence needed for remote attestation are up to date. The attestation also conveys the Developers wishing to debug their remote attestation service provider should be able to temporarily modify their cryptographic subsystem to behave in a similar manner as the sample_libcrypto. Why my Intel-NUC NUC7PJYH did not run the sample? 0 Kudos Copy link. Full Remote Attestation flow. For simplicity, the client and server are packaged and built together. 1. The following example shows a policy for an Intel SGX TEE. For Intel SGX remote attestation for example, an Intel SGX quote is verified using the certificate chain issued by Intel which is only valid for SGX platforms. It covers the Intel SGX SDK version 1. I remove the 4-byte TSV header and now sgx_report_attestation_status works perfectly. Product Support Forums; FPGA; Memory & Storage; Visual Computing; Embedded Products Intel Software Guard Extensions (SGX) is a set of instruction codes implementing trusted execution environment that are built into some Intel central processing units (CPUs). 509 cert has been added to the DEV IAS environment. Gramine Shielded Containers (GSC) client — Permits existing Intel SGX enclaves to use Intel Trust Authority remote attestation with very few changes. Resolution. from Intel), describes an example of remote attestation. Handle 0x0000, DMI type 0, 26 bytes BIOS Intel SGX remote attestation sample code. The quote in Intel SGX represents a digitally signed attestation generated Intel® SGX provides the means for remote entity to verify assertions from an enclave instance. So, the mystery thickens. Note: Currently, remote attestation verification is only supported in Azure ACC VMs, but Intel will be expanding support for this with Open Enclave SDK more broadly moving forward. You can use the Intel Trust Authority Go client libraries to integrate Intel SGX or Intel TDX attestation into your application. (2018) leverage SGX remote attestation to enhance the TLS protocol with platform specific information. Intel® Software Guard Extensions (Intel® SGX) To be able to seal sharable data blobs between two different CPUs would require the use of SGX remote attestation to provision shared key(s) to both enclaves that could then be used to seal/unseal the data. Hello, Basing on this code sample I am trying to implement the Service Provider in Node JS, which communicates with the ISV app from the RA example. Hi, all, We've tested the remote attestation sample code on 2 platforms available to us: Dell Poweredge R340 (CPU: Intel(R) Xeon(R) E-2174G), and Lenovo ThinkSystem SR250 Rack Server (CPU: Intel(R) Xeon(R) E-2288G).

When the remote attestation is successful, the enclave can act as a hardware root of trust and can be used as an execution environment for sensitive operations. At the confidential computing summit, NVIDIA and Intel shared a I've tried the sample code shipped with the SGX SDK. Refer to the SGX SDK sample, RemoteAttestion, for an example of passing encrypted data to an enclave after doing remote attestation. Do we have any sample code/example of remote attestation using the replying party ? -Thanks. Intel® SGX allows an enclave instance to obtain keys that are bound to the platform and the enclave. ECDSA Remote Attestation/Data Center Attestation Primitives (DCAP) Info: a. This software also uses the remote attestation protocol used by intel SGX. Note: Currently those sample only works on SGX-FLC For example, a cloud service that performs image pro- Software attestation proves to a remote computer that it is communicating with a specific secure container hosted by a tion, such as Intel’s SGX-related patents, to fill in some of the missing details in the SGX description. Overall View of Intel SGX Infrastructure Services Platform Provisioning In order to transform a local REPORT into a remotely verifiable SGX remote attestation uses the Intel SGX PSW’s AESM service and the Intel IAS service (for EPID flows) or DCAP libraries (for ECDSA/DCAP flows) under the hood. SGX Remote Attestation with TLS. Rece I am new in Intel SGX and doing an academic project. cpp in the RemoateAttestation project is like this: Firstly, when attempting to make and run the Remote Attestation Sample file to perform Intel SGX Remote Attestation, I get an output similar to the attached 'RA. They are different in the sgx-ra-sample. Intel® SGX Data Center Attestation Primitives (Intel® SGX DCAP) Product Brief In this article. Hello Enio. The evidence is sent to Intel Trust Authority for attestation. Think of it as an impenetrable Product Support Forums. Sam123 True if the Intel SGX debug attribute is enabled, otherwise false. swami@gmail. Load an application into Intel SGX enclave. integrated attestation for Intel SGX enclaves with TLS . I can successfully execute all other sample codes.
