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 ...
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,...
Abstract: This paper introduces the idea of Hill encryption algorithm, encryption and decryption process of Hill cipher, modularalgebra knowledge in the process of encryption and decryption. Combined with an example, using mathematical knowledge and Matlablanguage, it explains how to find the Hill ...

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
This repository contains a Python implementation of the Hill Cipher encryption algorithm using the NumPy library. The Hill Cipher is a polygraphic substitution cipher that encrypts messages by dividing them into blocks and then performing mathematical op
Hill CipherEncryptionDecryptionSelf-invertible matrixIn this paper, methods of generating self-invertible matrix for Hill Cipher algorithm have been proposed. The inverse of the matrix used for encrypting the plaintext does not always exist. So, if the matrix is not invertible, the encrypted text ...
For the decryptionprocess, we will just follow the exact opposite steps. 3) Hill Cipher The Hill cipher is based on polygraphic substitution that is it works on multiple letters at the same time, introduced by Lester Hill in 1929. This method related to the matrix theory of mathema...
