METHOD FOR IMPLEMENTING IN AN ELECTRONIC COMPONENT A CRYPTOGRAPHIC ALGORITHM FOR FINDING THE PUBLIC EXPONENT

摘要

The invention concerns a method for implementing in an electronic component a cryptographic algorithm using calculating means. The invention is characterized in that it consists in carrying out the following steps: a) selecting a value e among a specific number of values eI, ei being integers, b) checking if ei verifies a predetermined relationship: if so, then e=ei, and storing e for use in calculating said cryptographic algorithm.
