WebJan 28, 2024 · ForkAE is a family of authenticated encryption (AE) schemes using a forkcipher as a building block. ForkAE was published in Asiacrypt'19 and is a second-round candidate in the NIST lightweight cryptography process. ForkAE comes in several modes of operation: SAEF, PAEF, and rPAEF. WebMar 19, 2024 · Forkciphers are a new kind of primitive proposed recently by Andreeva et al. for efficient encryption and authentication of small messages. They fork the middle state of a cipher and encrypt it twice under two smaller independent permutations. Thus, forkciphers produce two output blocks in one primitive call. batty meme
