摘要： A method for the secure application of a cryptographic algorithm of the RSA type in an electronic component obtains the value of a public exponent e from a given set of probable values, without a priori knowledge of that value. Having determined the value for the public exponent e, the application of countermeasures using the value of e, to block error attacks and side channel attacks, particularly of the DPA and SPA type, are carried out on the application of a private operation of the cryptographic algorithm.

摘要： The invention relates to method of performing a modular multiplication using numbers with 2n bits. The method includes the steps of breaking the numbers (A, B) down into a 2n base or a U base, U being a suitable integer; and, subsequently, performing MultModDiv—and/or MultModDivlnit-type elementary operations on the numbers with n bits resulting from the first step. The invention also relates to a method of calculating a Euclidean multiplication/division. The invention can be used for cryptographic calculations.

摘要： The invention relates to a cryptographic method involving an integer division of type q=a div b and r=a mod b, wherein a is a number of m bits, b is a number of n bits, with n being less than or equal to m, and bn−1 being non-null and the most significant bit of b. In addition, each iteration of a loop subscripted by i, which varies between 1 and m−n+1, involves a partial division of a word A of n bits of number a by number b in order to obtain one bit of quotient q. According to the invention, the same operations are performed with each iteration, regardless of the value of the quotient bit obtained. In different embodiments of the invention, one of the following is also performed with each iteration: the addition and subtraction of number b to/from word A; the addition of number b or a complementary number /b of b to word A; or a complement operation at 2n of an updated datum (b or /b) or a dummy datum (c or /c) followed by the addition of the datum updated with word A.
