Combined and General Methodologies of Key Space Partition for the Cryptanalysis of Block Ciphers
This paper proposes two new methods of key space partitioning for the cryptanalysis of block ciphers.The first one is called combined methodology of key wd80efzx space partition (CoMeKSPar), which allows us to simultaneously set some of the first and last consecutive bits of the key.In this way, the search is performed using the remaining middle bi
