Design and sopc-based realization of a video chaotic secure communication scheme

This paper proposes a new approach for hardware realization based on a system with programmable chip (SOPC) technology. The main feature of the SOPC-based scheme is that it can make full use of both FPGA and ARM, where the FPGA is used for video capturing, displaying, encrypting and decrypting, the ARM is adopted for TCP/IP protocol, Ethernet sending and receiving. SOPC technology gives full play to the advantages of both FPGA and ARM that complement each other, leading to better real-time performance and is more convenient for hardware realization. In addition, some results of security analysis are also given. Hardware realization results verify the feasibility and effectiveness of the proposed SOPC-based approach.
