分组密码算法SM4的低复杂度实现
Low Complexity Implementation of Block Cipher SM4 Algorithm
摘要
Abstract
A basic architecture is proposed for reducing the implementation complexity of SM4 block cipher.The architecture reuses the hardware of encryption/decryption and key expansion module because the encryption/decryption algorithm is very similar with the key expansion algorithm.Optimum trade-off among control-logic complexity,reused-module complexity and throughput is realized through careful analysis and choose of specific realization.A SM4 cipher IP is designed based on this architecture.The designed IP's cost is only 55％ of the traditional design in Field Programmable Gate Array(FPGA).The IP is also synthesized under the SMIC 0.18 μm CMOS process.Its area is 0.079 mm2 with 100 Mb/s throughput.Experimental results of synthesis show that the proposed architecture can reduce the implementation complexity of SM4 block cipher efficiently.关键词
