WebIn Sections 3 and 4, we introduce our new key exchange protocols and public key algorithm. Section 5 discusses implementation aspects of the proposed scheme by reviewing 79 Daghigh, Khodakaramian Gilan and Seifi Shahpar the methods for computing isogenies between elliptic curves and presenting an example.
WebCostello and Frengley do manage to use up to (11,11)-isogenies, but only as a decisional tool to detect (N,N)-split Jacobians. The reason for these restrictions is that computing isogenies between abelian surfaces is typically a lot harder than isogenies between elliptic curves.
