The Endomorphosis Ring of the Base Curve

The effectiveness of the attack depends on exactly what's going on with this power of two minus this power of three. And so if we talk about the two papers, the paperis clearly there's to be two groups of authors that have been working on thus am. So you need to be able to compute this. We random isogeny. You need tobe able computed on points. O, you need to really be able toval at it. Am na's degree is large, and you don't have a lot of control over it. But they're all ased on the same observation of kane. Elo, if you know the endomorphos ring v zero, then
