HOACS: Homomorphic Obfuscation Assisted Concealing of Secrets

This repository contains the C code implementations used in the research paper "HOACS: Homomorphic Obfuscation Assisted Concealing of Secrets to Thwart Trojan Attacks in COTS Processor" by T Hossain, M Showers, M Hasan, T Hoque, published as an arXiv preprint arXiv:2402.09701 in 2024.

Overview

The HOACS (Homomorphic Obfuscation Assisted Concealing of Secrets) project aims to enhance the security of COTS (Commercial Off-The-Shelf) processors against Trojan attacks through the application of homomorphic obfuscation techniques. This repository includes the C implementations of various algorithms that support the theoretical concepts presented in our paper, focusing on operations within the Residue Number System (RNS) to achieve secure computation.

Content

The repository contains implementations of the following RNS operations:

• Addition in RNC
• Subtraction in RNC
• Shifting in RNC
• Multiplication in RNC
• Division in RNC
• Exponential Operation in RNC
• Modulus Operation in RNC
• Equality Operation in RNC

Each of these operations is crucial for the homomorphic obfuscation techniques discussed in our paper, providing a foundational layer for building secure computation protocols on COTS processors.

Usage

To use the code in your projects, clone this repository and include the desired C files in your project. Each file is a standalone implementation of the corresponding RNS operation.
