Abstract

In this paper, we propose a parallel chaos-based encryption scheme in order to take advantage of the dual-core processor. The chaos-based cryptosystem is combinatorially generated by the logistic map and Fibonacci sequence. Fibonacci sequence is employed to convert the value of the logistic map to integer data. The parallel algorithm is designed with a master/slave communication model with the Message Passing Interface (MPI). The experimental results show that chaotic cryptosystem possesses good statistical properties, and the parallel algorithm provides more enhanced performance against the serial version of the algorithm. It is suitable for encryption/decryption large sensitive data or multimedia.
