In view of the current network video transmission process by a single program implementation of encryption and rely on computer platform, we design for video network environment of the integrated encryption scheme of safety critical embedded router. The use of FPGA development system and uClinux will Qi hyperchaotic, logistic mapping, baker map and cat map algorithm is applied to video encryption and decryption, the encryption, on-line and off-line encryption and random encryption and multiple encryption way so that data security is stronger; create a subcontracting agreement to resolve the uClinux, TCP / IP stack small defects and the problem of packet loss. After long time testing, the system can run stably and has high security. System used by the processor for 87MHz, memory is 10m, with lower hardware cost achieve the complicated encryption algorithms, high price, and has good of transplantation and the application foreground of the platform broad.
