Improved Masking for Tweakable Blockciphers with Applications to Authenticated Encryption

Explore the advancements in masking techniques for tweakable blockciphers and their applications to authenticated encryption in this 25-minute conference talk presented at Eurocrypt 2016. Delve into topics such as OCB, XMasking-based tweakable blockciphers, word-based powering-up masking, and Gray code masking. Learn about the high-level contributions, including Masked Even-Mansour (MEM) and its design considerations. Examine the uniqueness of masking and "bare" implementation results. Discover the application to authenticated encryption through OPP and its implementation parallelizability. Gain insights from Robert Granger, Philipp Jovanovic, Bart Mennink, and Samuel Neves as they present their research findings and conclude with the implications of their work.
