【 摘 要 】

In this paper, we have developed a block cipher by applying an iterative method. In the process of encryption, we have used a key matrix (K) in which all the elements are binary bits. In the process of decryption, we have utilized the modular arithmetic inverse (K^-1). In the process of encryption, the elements of the plaintext and the elements of the key are thoroughly mixed so that the strength of the algorithm increases remarkably. In this we have obtained the ciphertext for large blocks of plaintext.
