【摘要】：SM4算法是我国公布的第一个商用分组密码算法,目前已经得到了广泛的应用。为更好地适应物联网中资源受限设备处理能力低、存储空间小等特点,设计并实现了基于资源重用的SM4算法轻量级处理架构。子密钥扩展和轮函数交替使用核心电路完成子密钥生成及加/解密运算,无需额外存储32轮迭代所需子密钥。密钥存储和检测电路以及可正/逆序生成固定参数的实时生成电路,可大幅提高解密处理效率。实验结果表明,所设计的轻量级处理架构资源占用小、品质因数高,非常适合于在物联网中资源受限设备上使用,具有广阔的应用前景。
[Abstract]:SM4 algorithm is the first commercial block cipher algorithm published in China and has been widely used. In order to better adapt to the characteristics of low processing capacity and small storage space of resource-limited devices in the Internet of things, a lightweight processing architecture of SM4 algorithm based on resource reuse is designed and implemented. The sub-key expansion and the rotation function alternately use the core circuit to complete the sub-key generation and encryption / decryption operations without the additional storage of the 32 rounds of iterative subkeys. The key storage and detection circuit and the real-time generating circuit which can generate fixed parameters can greatly improve the efficiency of decryption processing. The experimental results show that the designed lightweight processing architecture has the advantages of low resource occupation and high quality factor, which is suitable for use in resource-limited devices in the Internet of things, and has a broad application prospect.
