Hill Cipher Encryption Technique Pdf 1 encryption 1.1 formula the general formula for encrypting text using the hill cipher algorithm is k × p mod 26. where k is our n × n matrix that serves as the key. the determinant of k must be relatively prime with 26. p is our text we want to encrypt in the form of an n × 1 matrix. In this work, we present a novel hill cipher security method that utilizes gaussian integers from number theory.
Pdf Image Encryption Algorithm Through Hill Cipher Shift 128 Cipher To encrypt a message using the hill cipher we must first turn our keyword into a key matrix (a 2 × 2 matrix for working with digraphs, a 3 × 3 matrix for working with trigraphs, etc.). The hill cipher is based on linear algebra and overcomes the frequency distribution problem of the caesar cipher that was previously discussed. the rest of this paper will be devoted to an explanation of the hill cipher, its shortcomings, and one way to secure the cipher further. Since the letter frequencies are masked the hill cipher is considerably more difficult to crack than a monoalphabetic substitution that is vulnerable to frequency analysis. Using a known plaintext attack, we can break the hill cipher with n blocks (of n letters) of matching plain ciphertext pairs. consider the following: let's say we know that "ma" encrypts to "ku" and that "th" encrypts to "mt".
