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...
Linear cryptanalysis, along with differential cryptanalysis, is an important tool to evaluate the security of block ciphers. This work introduces a novel extension of linear crypt...
Feistel Network, consisting of a repeated application of the Feistel Transform, gives a very convenient and popular method for designing “cryptographically strong” permutations...
KASUMI is a block cipher which consists eight Feistel rounds with a 128-bit key. The confidentiality and integrity of UMTS, GSM and GPRS mobile communications systems depend heavi...
This paper describes truncated and impossible differential cryptanalysis of the 128-bit block cipher Camellia, which was proposed by NTT and Mitsubishi Electric Corporation. Our wo...
