Abstract
Chaotic maps have been widely used in data encryption. Various chaos map based encryption and decryption algorithms are used but are found to be insecure. Hence a new method is implemented based on BB (Brahmagupta-Bhaskara) equation which is combined with chaos to give a non linear dependency and thus improved security. This paper also improves security by changing chaotic sequence generators and permutation technique. The proposed algorithm is designed and realized using MATLAB and Xilinx ISE softwares.
