摘要:In this paper, the design o f digital image s ecurity system is describ ed for CCTV system based on AESciph er algo rith m. Th e implemented s ystem can p ro tect so me prob lem s such as the h ackin g o f im ag e dataan d revealin g of im ag es relating to ind ividu als comp ared to ex isting CCTV sys tems . Fro m th e exp erimentalresults, we showed that th e p rop osed sys tem b ased on AES ciph er alg orith m is correctly op erated inco nvention al CCTV en viro nment. In th e propo sed sy stem , a decryp tio n m odu le fo r View Server has b eenco ded using C++ langu ag e. Also , an en cryp tion mo dule has b een describ ed in Verilo g HDL, and it h asb een successfu lly imp lem en ted with Xilinx FPGA (Spartan XC2V200 ) using the ISE 9.1i too l
