摘要
FESH分组密码算法为2019年全国密码算法竞赛中进入第二轮评选的密码算法。文章对该算法的FESH-128-128型进行Verilog HDL高速实现,在有限状态机的基础上对顶层模块采用流水线设计方法进行优化,通过寄存器存储中间数据,提高运行效率。实验结果表明,在软件Quartus Ⅱ 15.0上使用5CEFA7F31C6芯片进行综合设计,采用流水线设计方法进行优化后,算法最高运行速率达到296.74 MHz,相较于有限状态机实现提高了98.28%;吞吐率达到37.98 Gbps,相较于有限状态机实现提升了约33倍。
The FESH block cipher algorithm is the cipher algorithm that entered the second round of selection in the 2019 national encryption algorithm competition.In this paper,the FESH-128-128 type of the algorithm is implemented in Verilog HDL at a high speed.On the basis of the finite state machine,the top-level module adopts the pipeline design method to optimize,and the intermediate data is stored in the register to improve the operating efficiency.The results show that the 5CEFA7F31C6 chip is used for synthesis on the software Quartus Ⅱ 15.0,and the pipeline design method is used to optimize the maximum operating speed of 296.74 MHz,which is 98.28%higher than the finite state machine implementation;the throughput rate reaches 37.98 Gbps,which Compared with the finite state machine,the realization is improved by about 33 times.
