Abstract

SM4 is a popular block cipher issued by the Office of State Commercial Cryptography Administration (OSCCA) of China. In this paper, we use the bit-slicing technique that has been shown as a powerful strategy to achieve very fast software implementations of SM4. We investigate optimizations on two frontiers. First, we present a more efficient bit-sliced representation for SM4, which enables running 64 blocks in parallel with 256-bit registers. Second, we describe an optimized algorithm for data form transformations, also allowing efficient implementations of SM4 under Counter (CTR) mode and Galois/Counter mode. The above optimizations contribute to a significant performance gain on one core compared with the state-of-the-art results. This work is an extension of the conference paper at Inscrypt 2022, awarded the best paper award.

SM4的位切片实现和新的性能记录

SM4是由中国国家商业密码管理局办公室(OSCCA)发布的一种流行的分组密码。在本文中，我们使用位切片技术作为一种强大的策略来实现非常快速的SM4软件实现。我们研究了两个前沿的优化。首先，我们为SM4提供了一种更有效的位切片表示，它支持使用256位寄存器并行运行64块。其次，我们描述了一种数据形式转换的优化算法，也允许在计数器(CTR)模式和伽罗瓦/计数器模式下有效实现SM4。与最先进的结果相比，上述优化有助于在一个核心上获得显着的性能增益。这项工作是在Inscrypt 2022会议论文的延伸，获得了最佳论文奖。
