摘要： The invention relates to a method for handling data between two memory areas of an electronic component having at least one working memory area for carrying out operations on the component, which bring into play at least some of the data. The same memory areas are used for executing an operation, whatever the operation to be executed is, in such a manner that each operation has a hidden signal trace that is identical in terms of location leakage outside the component.

摘要： An asymmetrical cryptographic method applied to a message M includes a private operation of signing or decrypting the message M to obtain a signed or decrypted message s. The private operation is based on at least one modular exponentiation EM in the form EM=MA mod B, A and B being respectively the exponent and the modular exponentiation EM. The private operation includes the following steps: calculating an intermediate module B*, an intermediate message M* and an intermediate exponent A*, based on B, M and/or A; the intermediate module B* being deterministically calculated and the intermediate message M* being randomly calculated; calculating an intermediate modular exponentiation EM*=MA mod B*; and calculating the signed or decrypted message s based on the intermediate modular exponentiation EM*. An electronic component for implementing the cryptographic method is also disclosed.

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.
