Cover and iterative learning control for and decryption in secure communication

Abstract

Typical cover techniques adopted in the conventional secure communication schemes are the additive masking and modulation by multiplication. In order to enhance security, in this paper, the new masking and decryption methods were given by iterative learning control algorithm for secure communication. In order to enhance security, the paper proposed the nonlinear masking method to apply to the traditional items and used the iterative learning control algorithm to decrypt. The algorithm reconstructed the information signal completely and analyzed the robustness and convergence of learning algorithm about the initial error and output error. The convergence conditions were given and the simulations shown in the algorithm can reconstruct the signal in secure communication.
