Etude et modélisation de circuits résistants aux attaques non intrusives par injection de fautes

Abstract : New hardware cryptanalysis methods such as fault-based attacks have shown their efficiency to break cryptosystems. This work is focused on the development of new techniques and tools that enable the design of robust circuits against fault injection attacks (Differential Fault Analysis: DFA). The study and the design of resistant asynchronous circuits against these attacks are particularly addressed. We first specify a faults sensitivity evaluation of asynchronous circuits. Then, hardening techniques are proposed in order to improve circuits resistance and tolerance. Practical results are evaluated on asynchronous cryptographic circuits using a laser beam fault injection system. These results validate both the theoretical analysis and the hardening techniques, and confirm that asynchronous technology is an efficient solution to design secure systems.
