Laser fault injection through the front side (and consequently the metal-flls) of an IC is often performed with medium or small laser beams for the purpose of injecting bytewise faults. We have investigated in this paper the properties of fault injection with a larger laser beam (in the 100/im range). We have also checked whether the bit-set (or bit-reset)(More)

A b s t r a k t The AES is a standard encryption algorithm used in numerous cryptographic systems like smart cards, TPMs as well as in protocols like WPA2 or OpenSSL. Measuring the robustness of AES implementations against physical attacks is of utmost importance in order to guarantee the security of the system into which the AES is used. In this article,(More)
