Efficiency of a glitch detector against electromagnetic fault injection

Abstract : The use of electromagnetic glitches has recently emerged as an effective fault injection technique for the purpose of conducting physical attacks against integrated circuits. First research works have shown that electromagnetic faults are induced by timing constraint violations and that they are also located in the vicinity of the injection probe. This paper reports the study of the efficiency of a glitch detector against EM injection. This detector was originally designed to detect any attempt of inducing timing violations by means of clock or power glitches. Because electromagnetic disturbances are more local than global, the use of a single detector proved to be inefficient. Our subsequent investigation of the use of several detectors to obtain a full fault detection coverage is reported, it also provides further insights into the properties of electromagnetic injection and into the key role played by the injection probe.
