On the use of error correcting codes in secured circuits
V. Maingot, Régis Leveugle · HAL (Le Centre pour la Communication Scientifique Directe) · 2007
The robustness of a circuit designed for securityrelated applications depends on its capability to globally resist to various types of attacks, based either on observation (e.g. DPA) or perturbation (e.g. injecting faults with a laser). In the case of perturbations, strategies can be based on protections aiming either at detecting the attack or at trying to maintain a correct behavior. This paper discusses characteristics of these two types of approaches when using information redundancy and in particular Hamming codes.
