This paper presents a high-throughput fault-resilient hardware implementation of AES S-box, called HFS-box. If a transient natural or even malicious fault in each pipeline stage is detected, the corresponding error signal becomes high and as a result, the control unit holds the output of our proposed DMR voter till the fault effect disappears. The proposed low-cost HFS-box provides a high capability of fault-tolerant against transient faults with any duration by putting low area overhead, i.e. 137%, and low throughput degradation, i.e. 11.3%, on the original implementation.

基于 DMR 的容错 AES S-box 架构技术

本文介绍了 AES S-box 的高吞吐量容错硬件实现，称为 HFS-box。如果在每个流水线阶段检测到瞬时自然甚至恶意故障，相应的错误信号就会变高，因此，控制单元会保持我们提出的 DMR 投票器的输出，直到故障影响消失。所提出的低成本 HFS 盒通过将低区域开销（即 137%）和低吞吐量降级（即 11.3%）放在原始实现上，提供了针对任何持续时间的瞬态故障的高容错能力。
