[Abstract]:This paper reviews the current situation and existing problems of chaotic cryptography theory and application in the past, and makes a comprehensive review on it. This paper focuses on the progress of high-dimensional chaotic cryptography and its application and hardware implementation in multimedia secure communication in recent years, including basic theory, design method, typical applications and solutions to these problems. In the aspect of chaotic cryptography design and security performance evaluation, the following advances are reported: design of non-degenerate high-dimensional chaotic cryptography based on anti-control method to enhance the anti-degradation ability of digital chaos, design of non-degenerate digital domain chaotic system, and design of non-degenerate digital domain chaotic system. Multi-wheel encryption scheme with closed-loop feedback for high-dimensional chaotic long-period stream ciphers with finite accuracy and security performance evaluation of high-dimensional chaotic ciphers. In the aspect of application and hardware implementation of multimedia secure communication, the different application services for handheld devices such as mobile phone, computer arm FPGA DSP and so on are reported. The development of the application environment of real-time remote chaotic secure communication in WAN and WiFi wireless communication network and the application platform of multi-bit integration, and the establishment of demonstration and verification system, etc. This paper attempts to advance the research of future chaotic cryptography theory and its application at home and abroad.
