  • In this paper we propose a novel method based on highly randomly switching code sets to enhance communication security of an integrated system of navigation and communication. A Gold-Chebyshev (GC) sequence constructed in our novel approach can overcome the shortcoming of poor balance performance of a conventional chaotic sequence, by preserving the main advantages of the latter, which are the large code number and high confidentiality. Our proposed secure system can randomly select a code set from a pool of GC code sets. This greatly improves the system security performance. We have also carried out simulations of operations of the system using the MATLAB/Simulink. Our simulations verify the feasibility of applying the novel method in an integrated system of navigation and communication.
