摘　　要：提出了一种SM4和ZUC-256密码的硬件实现方案.首先对两个密码算法进行硬件语言描述,然后构建了两个可重构单元--可重构寄存器和可重构S-box单元,从而在实现两个密码算法的基础上,有效降低了资源消耗,提高了资源利用率.在现场可编程逻辑门阵列(field programmable gate array, FPGA)上进行硬件验证.结果表明,本密码可重构方案中的硬件开销有明显的降低.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 reduced.
