Design and Implementation of Chaotic Encryption Processor Based on DSP

A kind of chaotic encryption processor based on DSP,using RS232 serial-port communication interface, is designed and implemented,which can be run in the manner of stand-alone. The chaotic stream cipher that is hard to break is applied in the processor,so it can protect data from a special kind of analysis technique to chaotic masking. The performance indicates that it is secure,effective and applicable.
