MOE: Multiplication Operated Encryption with Trojan Resilience

In order to lower costs, the fabrication of Integrated Circuits (ICs) is increasingly delegated offshore contract foundries, making them exposed malicious modifications, known as hardware Trojans. Recent works have demonstrated that a strong form Trojan-resilience can be obtained from untrusted chips by exploiting secret sharing and Multi-Party Computation (MPC), yet with significant cost overheads. this paper, we study possibility building symmetric cipher enabling similar guarantees in more efficient manner. To reach goal, exploit simple round structure mixing modular multiplication binary matrix. Besides being motivated new block design for Trojan resilience, our research also exposes cryptographic properties multiplication, which independent interest.
