Abstract: A method and apparatus are proposed for cryptographic computations implemented in an electronic component. The method includes determining the cofactor of an elliptic curve E defined over a finite field Fq with q elements, the elliptic curve comprising a base point P having an order equal to n. The step of determining includes determining a value of floor((q+2ceil(b/2)+1+1)/n) when n>6?q, where the function ceil corresponds to the ceiling function, floor corresponds to the floor function, and b corresponds to the size q in number of bits of q.

Abstract: The process according to various aspects can be executed by a terminal for selecting an application executable at least in part by a secure module incorporated into the terminal, and may include a step for obtaining location information of the terminal, from a memory of the secure module, and a selection step of an application from the obtained location information.
