Explore a comprehensive talk from FSE 2013 on secure distance bounding protocols, presented by Ioana Boureanu, Aikaterini Mitrokotsa, and Serge Vaudenay. Delve into the concept of distance bounding and its applications in security systems, including relay attacks, mini attacks, and night access scenarios. Examine the role of distance bounding in payment systems and gravity-based security measures. Investigate interactive protocols, the notion of distance, and the importance of distance secrecy. Analyze key protocols, best attack strategies, and optimal security products. Gain valuable insights into this crucial aspect of cryptography and security engineering through this in-depth 59-minute presentation.
