Overloading the nonce: rugged PRPs, nonce-set AEAD, and order-resilient channels
JP Degabriele, V Karadžić - Annual International Cryptology Conference, 2022 - Springer
We introduce a new security notion that lies right in between pseudorandom permutations
(PRPs) and strong pseudorandom permutations (SPRPs). We call this new security notion …
