Abstract

In this paper, we have developed a block cipher by modifying the Feistel cipher. In this, the plaintext is taken in the form of a pair of matrices. In one of the relations of encryption the plaintext is multiplied with the key matrix on both the sides. Consequently, we use the modular arithmetic inverse of the key matrix in the process of decryption. The cryptanalysis carried out in this investigation, clearly indicates that the cipher is a strong one, and it cannot be broken by any attack.
