Cryptographic systems are typically designed to resist direct attacks on their algorithms or key storage. Yet, unexpected weaknesses can appear in the physical implementation of these systems, opening the way for “side channel” attacks. Instead of attacking a system or cryptographic algorithm directly, side channel attacks measure and analyze patterns in unintentionally leaked signals—such as power consumption, electromagnetic radiation, or even sound emissions—to extract sensitive information, such as secret keys. By sidestepping a system or chip’s defenses, side channel attackers have found a way to effectively break into virtually any system, even those we normally think of as being secure.
Side-Channel Resilient Protocols provide a powerful solution to this security vulnerability. Designed to resist information leakage through auxiliary channels, these protocols ensure that no valuable data can be siphoned off, regardless of the implementation environment. Side-Channel Resilient Protocols incorporate advanced techniques such as masking, blinding, randomizing execution times, or power analysis resistant design, to effectively shield your cryptographic functions from side-channel attacks.
