Reconfigurable design of state secret algorithm SM4 and ZUC based on FPGA
This paper proposes a hardware implementation scheme of SM4 and ZUC-256 ciphers.This scheme first provided hardware language description for the two ciphers,and then two reconfigurable units—reconfigurable register and reconfigurable S-box unit were constructed.Accordingly,based on the realization of two password algorithms,resource consumption was effectively reduced and resource utilization was improved.Hardware veri-fication was carried out using a field programmable gate array(FPGA).The results showed that the hardware overhead in the password reconfiguration scheme was significantly re-duced.
