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,...
Hill cipher According to the definition inwikipedia, in classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more th...

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...
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 mathem...
