Hill Cipher DecryptionTo decrypt the message, we turn the ciphertext back into a plain text, then simply multiply by the inverse matrix of the key matrix as "IFKVIVVMI" in letters. The inverse of the matrix used in the encryption is,...
Cryptography is a security mechanism which caters the security services of world in perfect manner. In this paper, the author has studied and performed the experimental analysis of modified hill cipher to perform encryption and decryption for invertible and noninvertible matrices.Pooja Sharma...
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 ...
