P. L. Sharma, M. Rehan . On Security of Hill Cipher using Finite Fields. International Journal of Computer Applications. 71, 4 ( June 2013), 30-33. DOI=10.5120/12348-8637
Hill cipher in cryptography is a symmetric key substitution algorithm, which is vulnerable to known plaintext attack. The present paper provides two fold securities to the existing Hill cipher by using the elements of finite fields and logical operator.
