ECM curve group order
It may be a dumb question but I haven't found the answer yet:
Given: ECM factoring result: 2^exponent-1,B1, B2, Sigma, Factor found Needed: Group order of the ecm curve (not the factor itsself) What is the fastest way / best program to the the ecm group order? All I have found is this. A hint would be appreciated. Thanks. |
