The application research of chaotic stream cipher in aircraft co-operation data classified transmission system
Beijing（2009）
摘要
The co-operation data classified transmission system which is embedded, autonomous, highly reliable, strongly real-time and highly secure, is special for the formation aircraft co-guidance. This paper proposes chaotic stream cipher based private key generating algorithm and field programmable logic device (FPGA) based hardware solutions and introduces the chaotic stream and irregular clock controller. Simulation demonstrates the improved A5/1 encryption algorithm realized with FPGA chip. The proposed encryption algorithm has good security and the easy realization and is easy to be programmed with high-speed hardware description language VHDL and realized with FPGA-based hardware. The proposed algorithm can meet the requirements of high-speed and secure encryption transmission for the aircraft co-operation data transmission system.
