In the mannered null electronic component which runs the cryptography algorithm which calculates open characteristic

摘要

This invention in the electronic component regards the method in order to execute cryptographic algorithm making use of calculation expedient. As for this invention, step below, a) specification from the value e _i (e _i to verify integer) inside selects value e, whether or not step and b where) e _i satisfies specified relationship, when filling up, it is e=e _i, the step which remembers e in one for calculation of cryptographic algorithm and, it consists of the fact that it executes.
