An Implementation of Trojan Side-Channel with a Masking Scheme

Abstract

Hardware trojans have posed great threats to the security of cryptographic devices, due to their invisibility and difficulty of removal. Trojan side-channel (TSC) is a kind of hardware trojan which leaks side channel information of the secrets in the devices. In this article, we present a new implementation of TSC for FPGAs. In the experiments, to verify its feasibility, we analysis the leakage model of our TSC implementation on FPGAs. Moreover, to resist the TSC detection, we apply a masking technique to our scheme by blinding the output of our TSC.
