WebbWe provide an improved cryptanalysis on the KATAN family (a family of hardware-oriented block ciphers proposed in CHES 2009) based on the boomerang attack. In the related-key setting, we were able to greatly improve upon the previous results to achieve the best results, namely 150 and 133 rounds by far for KATAN48/64 respectively. WebbKATAN is one of the existing lightweight families of block ciphers. The KATAN family splits into two sets. The first set is the KATAN and takes blocks of 32, 48, or 64 bits. The second set is the KTANTAN; it also takes blocks of 32, 48, or 64 bits but differs in the key scheduler. All ciphers in the KATAN family have 80-bit keys. python today\u0027s date yyyy-mm-dd
