Characterisation and Estimation of the Key Rank Distribution in the Context of Side Channel Attacks

Explore a comprehensive analysis of key rank distribution in side-channel attacks presented at Asiacrypt 2016. Delve into the current model for side-channel attacks, factors affecting success, and evaluation approaches. Examine the concept of key rank as a random variable and learn techniques for estimating and improving rank distribution. Discover real-world experimental results from repeated DPA attacks on AES-128 implementation. Gain insights into distribution consistency, shape, and detailed analysis. Conclude with a proposed evaluation method for assessing side-channel attack effectiveness.
