Research ArticleOpen accessA Block Cipher using Feistal's Approach Involving Permutation and Mixing of the Plaintext and the Additive Inverse of Key MatrixAruna Varanasi, S. U. KumarIn this research, we have developed a block cipher for a block of size 112 bits by using an iterative method involving a permutation of the plaintext and the subkeys generated in each iteration. Here we have represented the plaintext as a matrix of f size 14×8, comprising binary bits. In the process of encryption, we have used a key … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,112 accessesView PDFCite
