This method comprises the steps of: (i) externally computing a cipher of the first identifier with a predetermined function fed with this first identifier and a predetermined secret key; (ii) transforming an accessible metal layer of the electronic device to form an activation pattern representing this externally computed cipher of the first identifier; (iii) getting a value representative of this activation pattern into the electronic device; and (iv) computing a second identifier with this transformed electronic device by feeding a reverse function of the predetermined function with this value and this secret key, to trigger a comeback to the sensitive mode if this second identifier is equal to the first identifier.

Abstract: There is disclosed a countermeasure using the properties of the Montgomery multiplication for securing cryptographic systems such as RSA and DSA against, in particular, safe-error injection attacks. In the proposed algorithm, the binary exponentiation b=ad mod n is iteratively calculated using the Montgomery multiplication when the current bit di of the exponent d is equal to zero. In that case, the Montgomery multiplication of the actual result of the exponentiation calculation by R is realized. Thanks to this countermeasure, if there is any perturbation of the fault injection type introduced during the computation, it will have visible effect on the final result which renders such attack inefficient to deduce the current bit di of the private key d.
