Orienting supersingular isogeny graphs


We introduce a category of O-oriented supersingular elliptic curves and derive properties of the associated oriented and nonoriented-isogeny supersingular isogeny graphs. As an application we introduce an oriented supersingular isogeny Diffie-Hellman protocol (OSIDH), analogous to the supersingular isogeny Diffie-Hellman (SIDH) protocol and generalizing the commutative supersingular isogeny Diffie-Hellman (CSIDH) protocol.
