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,...
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...

Hill Cipher is one of the classic symmetric encryption algorithms widely used in cloud data security. Although the hill cipher principle is relatively simp
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 ...
polyalphabetic substitution cipher that encrypts text by pairing each letter of the plaintext with a key and performing modular subtraction. It’s similar to the Vigenère cipher but uses subtraction instead of addition, making it its own reciprocal—encryption and decryption are performed with the ...
