Entropy of encrypted image using advanced Hill Cipher algorithm is greater than that of Hill Cipher and original image. The results show that advanced Hill Cipher algorithm is better than Hill Cipher algorithm for image cryptography.doi:10.1007/978-981-16-0443-0_34Jagadeesh Basavaiah...
Playfair cipher (aka Playfair square) is a cryptography technique used for manual encryption, it was introduced by Charles Wheatstone in 1854 but it was popularized by Lord Playfair hence his name used. The Playfair cipher was used in world war I by the British army and in World war...
In the language of cryptography, codes are known as ciphers, encoded messages are known as plaintext, and coded messages are known as cipher 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 ...
The Hill cipher algorithm is one of the symmetric key algorithms that have several advantages in data encryption. However, a main drawback of this algorithm is that it encrypts identical plaintext blocks to identical ciphertext blocks and cannot encrypt images that contain large areas of a single...
Cryptography is one of the methods to attain security. The Hill cipher is a symmetric encryption algorithm vulnerable to the attack of knownplaintext. This paper proposes a modification to the Hill cipher. In the proposed cryptosystem, a prime circulant matrix is shared as a secret key and a ...

Cryptography is the core of information security, and the Hill cipher is one of the most important methods for cryptography. For the purpose of the improvement in the security of traditional Hill cipher (THC) with time-invariant key, a new dynamic Hill cipher (DHC) method with time-varying ...
Added extensive cipher and plain text library, it can be found in the "Ciphers/" folder. Internally the score calculation is now using entropy instead of the index of coincidence. This may change the scores you are used to seeing a little bit. A small adjustment to the n-gram ini files...
