Challenges in Feasible Simulation of Side-Channel Attack Resistance for Cryptographic Hardware

Cryptographic hardware plays a crucial role in establishing the Root of Trust to ensure information security in various applications, including IoT devices, autonomous driving systems, and digital ecosystems. Critical Security Parameters (CSPs) like cryptographic engines and keys must be securely stored within a hardware-protected cryptographic boundary to enhance security. This paper comprehensively reviews methods for evaluating resistance against Side-Channel Attacks (SCA). It introduces research that employs the signal-to-noise ratio of Side-Channel (SC) leakage. The objective is to facilitate an efficient evaluation of SCA resistance for the development of practical designs of cryptographic hardware.
