As the Limited speed of realizing encryption algorithm using PC , the special encryption chip costs more and has a relatively long development cycle, this paper presents the design and implementation procedure of a data encryption system based on a kind of high speed DSP. The system uses TI's high speed floating DSP achieved 3DES encryption algorithm, the USB2. 0 interlace chip is used to complete the communication of DSP and PC, The experimental results indicate that the encryption system can operate reliably and quickly and it can be expanded into a real-time data encryption system.
