A Block Cipher using Feistal’s Approach Involving Permutation and Mixing of the Plaintext and the Additive Inverse of Key Matrix
Aruna Varanasi, S. Udaya Kumar · Journal of Computer Science · 2008
In 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 size 14
