Secured text communication using chaotic maps

Security has become vital issue in storage and transmission of digital data over insecure communication channel which can be achieved by using reliable encryption algorithms. Chaos based encryption techniques are more popular because of their exceptionally superior properties such as high security, simplicity and faster speed. In this paper, one of the chaos based text encryption algorithms is considered which employs modified Henon map and Sine map. The encryption capability of the algorithm is verified for different text data. Further, the empirical results of the chaos based algorithm are compared with RC4. Experimental findings reveal that the algorithm provides secure communication for text data of different file sizes.
