Abstract: This note defines Kravatte-SANE and Kravatte-SANSE. Both are session authenticated encryption schemes and differ in their robustness with respect to nonce misuse. They are defined as instances of modes on top of the deck function Kravatte, where a deck function is a keyed function with variable-length input strings, an arbitrary-length output and certain incrementality properties.
