Abstract :
This work addresses the problem of hardware attacks against cryptographic circuits. The most dangerous side-channel attack: the differential power analysis (DPA) is discussed, as well the state of art countermeasures. Then new reconfigurable system on chip resistant against DPA attacks is proposed. Results shows that our architecture is efficient against DPA attacks, but also outcomes the performance of classical implementation of modular exponentiation, for key size exceeding 2048 bits, with a reasonable extra area overhead
