Upgraded to OpenSSL 3.0.14. Upgraded Intel(R) Integrated Performance Primitives (IPP) Cryptography library to version 2021.12.1. Supported FIPS 140-3 Certifiable IPP Crypto based Trusted Library. Upgraded Intel SGX Architecture Enclaves based on new IPP crypto library. Upgraded Intel DCAP Quote Verification Enclave to integrate OpenSSL/SgxSSL 3.0.14. Removed Intel DCAP PCCS from repository. Added Ubuntu* 24.04 LTS 64-bit Server support. Fixed bug. Note that PCCS is not available from this release. Please follow DCAP installation guide to use `PCCSAdminTool` to retrieve the attestation collaterals or use old version PCCS. Signed-off-by: Li, Xun <xun.li@intel.com>
Intel(R) EPID SDK
The Intel(R) Enhanced Privacy ID Software Development Kit
Intel(R) EPID SDK enables adding Intel(R) EPID support to applications and platforms.
Intel(R) EPID is a cryptographic protocol which enables the remote authentication of a trusted platform whilst preserving the user's privacy.
-
For a given public key there are many (e.g., millions) of private keys. The key holders form a group.
-
Any key holder may sign against the one public key.
-
No one can tell which private key signed the data. This is the privacy property.
You can use Intel(R) EPID as a foundational building block for a multitude of security solutions.

Math Primitives
The source code used for math primitives in the Intel(R) EPID SDK is a subset of the Intel(R) IPP Cryptography library (version 2017 Update 2) written in pure C and not optimized for performance. For higher performance, you can use the commercial version of the IPP Cryptography library, which is available at https://software.intel.com/articles/download-ipp-cryptography-libraries.
More information on the optimized versions of Intel(R) IPP Cryptography library, including mitigations for a potential side-channel issue are available at https://security-center.intel.com/advisory.aspx?intelid=INTEL-SA-00060&languageid=en-fr.
