Abstract. In this paper, we study the security of 2Rschemes [17,18], which are the "minus variant" of two-round schemes. This variant consists in removing some of the n p...

We introduce KFC, a block cipher based on a three round Feistel scheme. Each of the three round functions has an SPN-like structure for which we can either compute or bound the adv...
