A Parallel Encryption Algorithm Based on Piecewise Linear Chaotic Map

Abstract EN

We introduce a parallel chaos-based encryption algorithm for taking advantage of multicore processors.

The chaotic cryptosystem is generated by the piecewise linear chaotic map (PWLCM).

The parallel algorithm is designed with a master/slave communication model with the Message Passing Interface (MPI).

The algorithm is suitable not only for multicore processors but also for the single-processor architecture.

The experimental results show that the chaos-based cryptosystem possesses good statistical properties.

The parallel algorithm provides much better performance than the serial ones and would be useful to apply in encryption/decryption file with large size or multimedia.
