Unmanned Aerial Vehicle Spread Spectrum Communication Encryption Technology Based on Improved L-C Cascade Chaos

A new L-C cascade chaotic encryption scheme is proposed to solve the data security problem in Unmanned Aerial Vehicle (UA V) communication system. This scheme adds control parameters for chaotic mapping and combines modulus calculation The existing single chaotic mapping has some problems such as simple structure and uneven output sequence. The scheme proposed in this paper overcomes these problems. Compared to single chaotic mapping encryption methods and traditional L-C cascade encryption methods, simulation results show that the improved L-C cascade chaotic encryption method greatly improves the security of UA V communication systems. This scheme can effectively encrypt data without affecting the spread spectrum communication of UAVs, and has a good application prospect.
