Abstract
The invention relates to a cryptographic method on a binary Edwards curve (BEC) by a binary extension field, the domain parameters of which are selected to enable an implementation adapted to a 32-bit or 64-bit hardware architecture to reduce the number of calculations and to guarantee a high security level against attacks. A list of binary extension fields is provided with associated primitive polynomials. For each of these binary extension fields, at least one optimum parameter of the BEC curve is disclosed with an optimum generating point.
