Abstract (en)
[origin: WO2004111833A1] The invention relates to a method for countermeasuring in an electronic component while using a public key cryptographic algorithm. The invention involves the use of a public key cryptographic algorithm containing an exponentiation calculation y=g &cir& d, in which g and y are elements of specified group G noted in a multiplicative manner and d is a predetermined number.
