How are matrices used in encryption
WebThe matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible n × n matrices (modulo 26). The cipher can, of course, be adapted to an alphabet with any number of letters; all arithmetic just needs to be done modulo the number of letters instead of modulo 26. Webin computers as a matrix. Various papers based on graph theory applications have been studied and we explore the usage of Graph theory in cryptography has been proposed here.
