Through the data storage of Rijndael encryption algorithm and the analysis of the characteristics of column mixing and wheel transformation, the author put forward some suggestions for the optimization of Rijndael. Meanwhile, the author design and realize the optimized Rijndael encryption through the SOPC (System on Program Chip). Based on the SOPC of Altera FPGA (Field Programmable Gata Array), the algorithm design is put forward and the center is the embedded soft core NiosII. It is also realized the encryption and decryption verification by using the ModelSim software. Compared with the traditional design, Rijndael encryption algorithm undergoes a great breakthrough. The author also evaluated the Rijndael encryption algorithm performance and logic resources occupation. PDFFulltextXMLReferencesCitation
