Explore the intricacies of multi-key security and the Even-Mansour construction in this 22-minute conference talk. Delve into block cipher design, key scheduling, and related key settings before focusing on multi-key security in the context of Even-Mansour (EM) and Ideal Block Cipher (IBC) models. Compare these approaches and distinguish between multi-user and multi-key scenarios. Examine real-world examples of frequent rekeying and understand the advantages of the Even-Mansour construction. Gain valuable insights into advanced cryptographic concepts and their practical applications in modern security systems.
