CS523-Project1

This is the repository for the project 1 of the CS-523 course

Overview

This project is splitted in two parts :
Part 1 : Secure MPC using a trusted third party for Beaver triplets generation
Part 2 : Secure MPC using homomorphic encryption for Beaver triplets generation

Main

Used only for Part 2
Syntax is as follows:
./mpc [PartyID] [Input] [CircuitID]

• PartyID : The ID of the Party
• Input : The Input of the party
• CircuitID : The ID of the circuit to compute. Circuits are stored in test_circuits.go

Note that the number of party should be equal to the number of inputs of the circuits, and that all parties should be run simultaneously.

Tests

Tests works for both parts. To change parts, set the boolean trusted in mpc_test.go:28to true for Part 1, false for Part 2. The tests can be run as follows:

• To run all tests : go test -v -run=.
• To run a test on a specific circuit with id e.g 1 : go test -v -run=^TestEval$/^circuit1$

Benchmark

Benchmark works for both parts. To change parts, set the boolean trusted in mpc_test.go:69to true for Part 1, false for Part 2. The benchmarks can be run as follows:

• To run all benchmarks : go test -v -bench=. -run=XXX
• To run a benchmark on a specific circuit with id e.g 1 : go test -v -bench=^BenchmarkEval$/^circuit1$ -run=XXX It is possible that the benchmarks fails because of too many open file. It that case, run it again with the tag -benchtime=XXXmsto avoid this issue.
