Hill Cipher AlgorithmSelf-Repetitive Matrix and Inverse MatrixThe core of Hill-cipher is matrix manipulations. It is a multi-letter cipher, for decryption the inverse of matrix requires and inverse of the matrix doesn't always exist. Then if the matrix is not invertible then encrypted text ...
In the language of cryptography, codes are known as ciphers, encoded messages are known as plaintext, and coded messages are known as cipher text. The main objective of proposed algorithm is to encrypt an image using a technique different from the traditional Hill Cipher. In this paper a ...
