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 ...
Hill Cipher is one of the classic symmetric encryption algorithms widely used in cloud data security. Although the hill cipher principle is relatively simp
which will be the cipher's key. Text is divided into blocks of size n, and each block forms a vector of size n. Each vector is multiplied by the key matrix of n x n. The result, vector of size n, is a block of encrypted text. Modular arithmetic is used; that is, all operation...
