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 ...
The encrypted text cannot be decoded if the key matrix is not invertible. The key matrix employed for encryption in the Involutory matrix generation method is invertible. As a result, we do not need to find the inverse of the key matrix during decryption. 展开 ...

The overall schematic of the encryption and decryption scheme. Full size image Generation of the chaotic sequence and preprocessing The key utilized in this algorithm is derived from the original image’s feature values obtained through a hash function. After preprocessing, these values are substituted...
it would be impossible for modern computing to crack aes in a reasonable amount of time. aes decryption aes decryption is straightforward and is essentially the same as aes encryption but in reverse. the recipient of the encrypted data also has a copy of the cipher used, so they perform each...
