Abstract

The multicore structure has been mainstreamed. The paper introduces a parallel chaos-based encryption approach in order to take advantage of the multicore processor. The chaotic cryptosystem is based on the logistic map. The parallel algorithm is designed with the shared memory model of the OpenMP. The experimental results show that the chaotic cryptosystem demonstrates the good statistical properties, and the parallel algorithm provides highly efficient performance against the serial version of the algorithm. The algorithm is suitable for processing large sensitive data, pictures and multimedia.
