摘要
利用激光器可以产生高维宽带混沌载波,并有望构建混沌激光保密通信信道。结合国内外的研究工作,从密码分析学的角度讨论了混沌激光通信的保密性能,介绍了混沌激光通信保密性能的研究进展,重点分析了目前报道的几种增强混沌激光通信保密性能方案的优缺点,同时提出了其他几种备用措施。
Wide bandwidth, high dimension chaotic carriers can be generated by lasers. It is hopeful to establish chaotic optical secure communication channel. Combined with the research both at home and abroad, the security performance of chaotic optical communication is demonstrated according to the cryptanalysis. The research progress in security analysis of chaotic optical communication is introduced. The advantages and disadvantages of several currently reported methods of enhancing the security of chaotic optical communication are analyzed in detail. Meanwhile, some other spare measures are proposed.
