Private Set Intersection with SGX

This repository contains the source code for the Proof-of-Concept implementation of Private Set Intersection with Enclaves, without trusting fully in the security of the enclave. The source code is part of a publication that will appear soon and we will update this repository once the publication is available.

The general structure of the code and interfacing with the SGX sdk was inspired by this sample application: https://github.com/svartkanin/linux-sgx-remoteattestation. Additionally the code now contains xxhash (in Enclave_shared/xxhash.h, BSD 2-Clause) and a further optimized variant of radix sort based on https://github.com/AwardOfSky/Fast-Radix-Sort.

The code requires the installation of Intel SGX here and the SGX driver here. Furthermore, also a developer account for the usage of IAS has be registered Deverloper account. The spid and api_key need to be ented in GeneralSettings.h

To compile the code:

• clone https://github.com/ARMmbed/mbedtls.git into dep/mbedtls and build according to its instructions. We tested with commit 8266acacc8d6e1c65fba9a048f56339d0827b2fe.
• clone https://github.com/bl4ck5un/mbedtls-SGX into dep/mbedtls-SGX and build according to its instructions. We tested with commit eab8e36a1e670a2fa66105735143eafa51931bff.
• install libjsoncpp-dev
• create a build directory and execute cmake.
