A Fully-Digital Em Pulse Detector

International audienceElectroMagnetic Pulse Injection (EMPI) has recently been demonstrated to be an efficient fault injection technique with many advantages especially when considering security issues of Systems on Chip (SoC) embedded on ball grid array packages, i.e. when adversaries do not have an easy access to the backside. EMPI must therefore be considered as a real threat against smartcards and SoC from now on. Among the usual countermeasures against fault attacks, one can identify the use of embedded sensors. If one can find voltage glitch or laser shot detectors in the literature, there is only one proposal which puts forward the idea of detecting ElectroMagnetic Pulse (EMP). However, this former sensor requires a fine tuning of some timing characteristics and, as a result, its use appears complex and even impractical with SoCs which are heterogeneous by nature and designed by worldwide teams. Within this context, this paper introduces and experimentally validates a new sensor allowing to detect EMP. Because the sensor is fully digital, it is low cost and above all fully compliant with the standard design flow of SoC

An Embedded Digital Sensor against EM and BB Fault Injection

International audienceFault Attacks methods like Electro-Magnetic PulseInjection or Body Biasing Injection have recently been demon-strated to be efficient against smartcards and Systems on Chip. As of now, security is a main constraint in product development, even for low-cost products riding the trend of the IoT (mostof these devices operate in hostile environments). Unfortunately, the implementation of hardware countermeasures has a costin silicon area, design time and performance. Therefore, it isimportant to develop protections while taking into account theircosts and easyness of implementation. One way to achieve theseends would be to have an all-in-one fully digital detector whoseintegration is compliant with the standard cell design flow. Inthis perspective, we propose an enhanced sensor to detect severaltypes of attacks by exploiting analog phenomena induced at thegate level, instead of the attack itself. This paper describes thedesign and the implementation into FPGAs of this sensor, as wellas experimental tests demonstrating its effectiveness for detectingelectro-magnetic and body bias fault injection attempts
