A Note on Key Ranking for Optimal Collision Side-Channel Attacks

Cezary Glowacz, DT Security

Abstract

In "Optimal collision side-channel attacks" (https://eprint.iacr.org/2019/828) we studied, and derived an optimal distinguisher for key ranking. In this note we propose a heuristic estimation procedure for key ranking based on this distinguisher, and provide estimates of lower bounds for secret key ranks in collision side channel attacks.
