Authenticated Encryption in the Face of Protocol and Side Channel Leakage

Explore authenticated encryption in the context of protocol and side channel leakage in this 25-minute conference talk presented at Asiacrypt 2017. Delve into the research paper by Guy Barwell, Daniel P. Martin, Elisabeth Oswald, and Martijn Stam, which examines the challenges and potential solutions in cryptographic systems. Learn about behavior assumptions, standard security notions, and restrictions in authenticated encryption. Discover the three types of goals in this field and understand the concepts of fictions, loops, and internal variables. Gain insights into SVTPRF, leakage, PRF Split, and backside leakage as the presenters discuss their findings and implications for cryptographic security.
