Masking Proofs Are Tight and How to Exploit it in Security Evaluations

Explore a comprehensive analysis of masking proofs and their implications for security evaluations in this conference talk presented at Eurocrypt 2018. Delve into the research conducted by Vincent Grosso and François-Xavier Standaert, examining the tightness of masking proofs and their potential exploitation. Gain insights into topics such as motivation for masking, leakage security, worst-case evaluations, bond bodies, and security graphs. Discover implementation details and practical relevance of the findings, while also considering limitations and potential applications for choosing the right security parameters.
