基于FPGA的SMS4高速数据处理算法设计

High-speed data processing design of SMS4 algorithm based on FPGA

随着集成电路的迅猛发展,为使数据通信安全性满足大数据时代的需要,文章详细研究SMS4算法,提出一种用双端口随机存取存储器(Random Access Memory,RAM)代替S盒的多路算法并行处理大数据的结构,并基于现场可编程门阵列(Field Programmable Gate Array,FPGA)实现这一算法。经仿真验证,所设计的结构都能正确处理大数据,其处理速度远超单个算法电路的处理速度。该算法与其他设计结构相比,其处理速度也占据相当优势。

With the rapid development of integrated circuits,in order to meet the security needs of data communication at the era of big data,after detailed study of the SMS4 algorithm,a structure of multi-channel algorithm parallel processing large data is proposed using dual-port RAM instead of S-box,and this algorithm is realized based on FPGA.Through simulation and verification,this structure can correctly handle large data,and its processing speed is more quickly than the processing speed of a single arithmetic circuits.Compared with other structures of the algorithm,its processing speed also occupies considerable advantage.
