Forkciphers are built upon secure block ciphers, andtheirspecificationsdependontheblockcipherused. … WebThe forkcipher framework was designed in 2024 by Andreeva et al. [ARVV18] for very short messages. It aims at producing authentificated encryption (AE) primitives. In addition to the privacy offered by an encryptionalgorithm,anAEensurestheintegrityofthedata.
WebNew cryptanalysis results on forkciphers are presented, showing that all components of a forkcipher must be carefully designed: the attack against ForkAES uses the weak diffusion of the middle rounds in reconstruction queries, but the attacked against ForkSkinny uses a weakness of the tweakey schedule in encryption queries. The forkcipher framework was … WebDec 8, 2024 · A forkcipher is a keyed function expanding a fixed-length input to a fixed-length output. We define its security as indistinguishability under chosen ciphertext attack. We give a generic construction validation via the new iterate-fork-iterate design paradigm.

WebFor this purpose, Andreeva et al. recently proposed forkciphers, which fork the middle state within a cipher and encrypt it twice further under two smaller independent permutations. So, forkciphers can produce two output blocks which can allow to authenticate and encrypt small messages more efficiently.
