摘要:In this paper, we have offered a generalization to the classical Feistel cipher. Here we have taken the plaintext in the form of a rectangular matrix. This matrix is decomposed into two parts wherein each one is a square matrix. In these, one of the parts is multiplied with a pair of keys K and L. In each round of the iteration process, we have carried out a thorough shuffling of the binary bits of the resulting plaintext, so that, confusion and diffusion are created intensively. The cryptanalysis carried out in this investigation clearly indicate that this cipher is a strong one, and it can be comfortably applied for the security of informationries.
