it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once. The explanation of cipher, which is below the calculator, assumes an elementary
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 ...
