| 摘 要： | SMS4是国内公布的无线局域网分组密码算法,文章在分析该算法特点的基础上,介绍了一种单轮内流水的高速引擎实现结构.通过配置多个引擎进行二次流水或并行处理,可以灵活调整输出性能和硬件开销,以适应不同应用的需求.在FPGA的对比测试中,相同输出性能下,具有比32轮流水线结构更小的硬件开销.而且在单引擎应用时,SMS4加/解密系统可以非常容易的在低端的Spartan Ⅱ XC2S50 FPGA上实现.

| Abstract: | SMS4 algorithm is the domestic encryption standard released for WLAN use.An inner-round pipelined,high-speed engine is proposed after analyzing the features of this algorithm.By using pipelined or parallel multi-engines,throughput and hardware cost can be easily adjusted according to different applications.Compared with the 32-stage pipelined structure,hardware cost is much lower under the same throughput.Moreover,the SMS4 encryption/decryption system can easily fit in a low-cost Spartan II XC2S50 FPGA in a single-engine implementation. |
