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 ...
The main objective of proposed algorithm is to encrypt an image using a technique different from the traditional Hill Cipher. In this paper a Modified Hill encryption and decryption technique has been proposed which uses an involuntary key matrix. The scheme is a fast encryption scheme which ...

Decryption − This shows the process of converting the ciphertext back into plaintext using the same secret key. Last Plaintext − It shows the original message again after decryption.Symmetric cryptography is exactly like having a secret language between friends. Suppose you and your friend hav...
