Impeccable Circuits III

Abstract: As a recent fault-injection attack, SIFA defeats most of the known countermeasures. Although error-correcting codes have been shown effective against SIFA, they mainly require a large redundancy to correct a few bits. In this work, we propose a hybrid construction with the ability to detect and correct injected faults at the same time. We provide a general implementation methodology which guarantees the correction of up to $t_c$-bit faults and the detection of at most $t_d$ faulty bits. Exhaustive evaluation of our constructions, by the open-source fault diagnostic tool VerFI, indicate the success of our designs in achieving the desired goals.
