Abstract :
In this paper, we propose a new cryptosystem that is faster than that of Baptista and present a uniform distribution in his ciphertext. To increase the security, we use the logistic map and a 3-dimensional piecewise linear chaotic map in the generation of the associations tables. Simulation results show that performance and security of the proposed cryptographic scheme are better than the Baptista algorithm.
