Static raw soft-error rates (SER) of COTS microprocessors are classically obtained with particle accelerators, but they are far larger than real application failure rates that depend on the dynamic application behavior and on the cache protection mechanisms. In this paper, we propose a new methodology to evaluate the real cache sensitivity for a given application, and to calculate a more accurate...
The robustness of a chip designed for security-related applications depends on its capability to globally resist to various types of attacks. This paper deals with protections against non invasive or semi invasive attacks. The two main categories are attacks based on power consumption (either by monitoring the current, e.g. DPA, or by monitoring the electromagnetic emissions, i.e. EMA) and attacks...
When designing circuits for security-related applications, the robustness depends on its capability to globally resist to various types of attacks, based either on the observation of the device (e.g. differential power analysis) or its perturbation (e.g. injecting faults with a laser). To deal with perturbations, two strategies are developed: detecting the attack or maintaining the proper functioning...
