Abstract
There has been a vast increase in the accumulation and communication of digital computer data in both the private and public sectors, much of this information has a significant value and requires protection. Encryption is an effective measure to be used in data security applications. With proper management controls, adequate implementation specifications, and applicable usage guidelines, data encryption no only aid in protection on data communication but can provide protection for a myriad of specific data processing applications. DSP is becoming more and more popular for their fast execution of instruction, wide applicability and relative low cost. Using DSP as processing unit to implement complex data encryption algorithms is a good idea. We developed a DSP based Data Encryption Communication System (D-DECS in abbreviation) to implement real-time data security applications. This paper not only presents a new architecture-- Single-Program and Multiple-Data stream (SPMD in abbreviation) architecture to build D-DECS, but also give out the complete features about hardware and software of the D-DECS we developed. Finally, we achieved a result that the D-DECS based on SPMD architecture has both good performance and nice flexibility to meet various requirements under different situations.
