摘要:

针对同时要求高吞吐率和高安全性的应用场景,提出了基于HRCA的高性能可扩展的SM4实现方案。首先,通过分析对 SM4 提取出的不同粒度的基础算核,提出了一个通用的粗粒度可重构计算单元;然后,为满足不同加密模式的需要给出了多种映射策略,根据不同策略将算法映射到重构计算单元;最后,通过分割控制平面和数据平面优化SM4整体架构。实验结果表明,使用所提方法,SM4算法在较低的资源消耗下吞吐量有了明显提高。

Abstract:

For the application scenarios that require high throughput and high security at the same time,based on HRCA,a high-performance scalable SM4 implementation scheme was proposed.Firstly,SM4 was formed to different calculation units of different granularity,and a general coarse-grained reconfigurable calculation unit was designed.Then,various mapping strategies were given for the purpose of satisfying different encryption modes,and the algorithm was mapped to the reconstructed computing unit according to different strategies.Finally,the SM4 overall architecture was optimized by dividing the control plane and the data plane.The experimental results show that using the proposed method,the SM4 algorithm has a significant improvement in throughput under lower resource consumption.

Key words: HRCA, SM4 cryptographic algorithm, reconfigurable computing, high-throughput
