Abstract
In this paper, we have developed a block cipher, by using a key bunch matrix and an additional key matrix. In order to carry out the decryption process, the decryption key bunch matrix is obtained, basing upon the encryption key bunch matrix, on using the concept of multiplicative inverse. In the cryptanalysis, we have found that, this cipher is a very strong one as it includes the additional key matrix and supported with modular arithmetic addition. From the viewpoint of efficiency and strength, this cipher is quite comparable with any other cipher available in the literature of cryptography.
