Application of the Advanced Encryption Standard and DM642 in the image transmission system

AES encryption algorithm and digital signal processing (DSP) technology are used in image encryption transmission system to make sure the information security and confidentiality in this paper. The basic principles, structure of the algorithm and design skills are introduced and analyzed. The program design is realized in DSP environment. An overall scheme of the image encryption transmission system based on the DM642 platform is given and the DSP program design process is explained. The AES encryption running speed of image encryption transmission system in CCS environment is tested as well. Experimental results show that AES encryption algorithm and DSP technology can be applied to the real-time and secure image transmission.
