Intel® Enhanced Privacy ID SDK 2.0.0

What's Included in the SDK

# SDK Components

The SDK is divided into logical components to separate responsibilities and create interfaces that you can re-implement using custom tools such as hardware accelerators.

The Intel® EPID SDK is divided into the following components:

Component | Description
--- | ---
member | Library containing APIs needed to implement a member
verifier | Library containing APIs needed to implement a verifier
common | Library containing common types and functions
math | Math primitives used by member and verifier
IPP | A C-only non-optimized subset of Intel® IPP
signmsg | A sample program showing how to sign messages
verfifysig | A sample program showing how to verify signatures
util | Common utilities used by samples
gtest | gtest unit test framework
Build Scripts | Scripts to configure and build the SDK
Sample Issuer Material | Sample keys and revocation lists

Math primitives are implemented in the math sub-component of common. The reference math primitive implementation is based on a non-optimized Vanilla C subset of the Intel® Performance Primitives. Math is designed so that you can replace its implementation to call custom hardware IP blocks or optimized libraries.

# Filesystem Layout

The Intel® EPID SDK has two filesystem layouts: the Source Layout and the Install Layout.

The Source Layout is what you find when you download the SDK and extract it to disk. This layout contains all of the files that you need to build the libraries, samples, tests, and data generated by the SDK.

The Install Layout is the layout of files under the `_install` folder after you build the SDK.

## Source Layout

The Source Layout is used by the build scripts in the Intel® EPID SDK to find components and files needed to create libraries and executables.

## Install Layout

The Install Layout contains the data developers need to develop and build their applications using the Intel® EPID SDK. Once built, the Install Layout has no dependency on the Source Layout, allowing developers to build the SDK once and reuse the built files in other locations or on other computers.
