WebIn this paper, we propose LightFORK, a forkcipher variant of LightMAC that achieves an improved query length independent security bound of the order of O ( q 2 / 2 n + s), maintaining full n bit message injection per primitive call, where n and s denote the block size and tweak size of the forkcipher respectively.

WebA multi-forkcipher (MFC) is a generalization of the forkcipher (FC) primitive introduced by Andreeva et al. at ASIACRYPT’19. An MFC is a tweakable cipher that computes s output blocks for a single input block, with s arbitrary but fixed. We define the MFC security in the ind-prtmfp notion as indistinguishability from s tweaked permutations. WebA 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.
