Abstract

Ensuring information security is of great significance to a satellite communication system. In this paper, a chaotic encryption scheme is proposed for a satellite communication system. Firstly, five chaotic sequences are generated by a five-dimensional chaotic system. And then, XOR, scrambling and interpolation are performed on the data in turn. The simulation results show that the bit error rate of this method approaches 0 when the SNR is greater than 18, and the bit error rate of the illegal receiver is as high as 35.3% when the correct key is unknown. Therefore, secure communication can be achieved.
