Research ArticleOpen accessA Large Block Cipher Using Modular Arithmetic Inverse of a Key Matrix and Mixing of the Key Matrix and the PlaintextV. U.K. Sastry, S. Udaya Kumar, A. Vinaya babuIn 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 … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,796 accessesView PDFCite
