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.
