Abstract: In this paper, a chaos-based cryptosystem using sampled chaos signals with frequency-domain aliasing is proposed. In this scheme, a higher degree of randomness of the running-key sequence is obtained, and an additional random seed consisting of the sampling frequency as the parameter is introduced. This leads to an enhancement of the cryptosystem security. Numerical and simulation results of a Lorenz cryptosystem are given to demonstrate the performance and effectiveness of the proposed approach. © 2004 IEEE.
