Encryption by Hill cipher and by a novel method using Chinese remainder theorem in Galois field

Encryption by Hill cipher and by a novel method using Chinese remainder theorem in Galois field Security can only be as strong as the weakest link. In this world of Communication, it is now well established that the weakest link lies in the implementation of cryptographic algorithms. Galois field is extensively used in coding. Hill cipher is an old symmetric key Technique of Cryptography. Here, a novel method of Hill cipher employing Galois field particularly GF(2 m ) has been used for Cryptography. This new type of cipher matrix utilises the polynomials as elements in GF(2 m ). Simulation results conform the utility of such a method in data security of private networks. The second method uses the Chinese Remainder Theorem (CRT) in GF(2 m ).

Abstract

Security can only be as strong as the weakest link. In this world of Communication, it is now well established that the weakest link lies in the implementation of cryptographic algorithms. Galois field is extensively used in coding. Hill cipher is an old symmetric key Technique of Cryptography. Here, a novel method of Hill cipher employing Galois field particularly GF(2 m ) has been used for Cryptography. This new type of cipher matrix utilises the polynomials as elements in GF(2 m ). Simulation results conform the utility of such a method in data security of private networks. The second method uses the Chinese Remainder Theorem (CRT) in GF(2 m ). This method is quite similar to RSA method.
