摘要
构造了具有小世界(WS)和无标度(BA)特性的束流输运网络,提出多种束晕-混沌的同步控制方法和3种保密通信的电路设计方案,并进行了仿真试验。在混沌复杂性研究的基础上,探索了一种混沌密码新算法,并成功地研制了链路混沌密码样机。同时研制了一种基于混沌加密算法和传统加密算法相结合的混沌加密系统,采用FPGA技术进行了硬件开发,已在互联网上实现了文件加密和解密的通信实验。在信息隐藏技术研究方面,实现了将加密信息隐藏到JPEG格式图片之中,实验和工程应用信息隐藏效果良好。
The halo-chaos beam transport network with small world （WS） and scale-free （BA） characteristics was constructed. Several synchronization control methods to realize the synchroni- zation control of halo-chaos and three kinds of circuit schemes for secure communication were pro- posed and simulation tests were done. Based on the research of chaos complexity, we explore a new method of chaotic algorithm, and successfully develope a data cryptograph prototype, which was applied to telephone communication networks with computer on line experimentally. We also proposed a chaotic encryption system based on combination of chaotic encryption algorithm with traditional algorithm, achieved the hardware developed by FPGA Technology, and realized file encryption and decryption communication experiment on the internet. In the research on informa- tion hiding technique, the encryption information is hided in JPEG format images, and the hiding effect is good by testing and engineering application.
