Hill Cipher (HC) is a matrix-based polygraph symmetric data encryption method. In 2011, Desoky et al. proposed the Bitwise Hill Crypto System (BHC) which is based on bit arithmetic. In this paper, we analyze BHC and show that it is insecure. Then, we propose a new modification using chaotic maps which provides better security.
