The SEA algorithm for endomorphisms of supersingular elliptic curves

Travis Morrison, Lorenz Panny, Jana Sotáková +1

For a prime $p>3$ and a supersingular elliptic curve $E$ defined over ${\mathbb{F}}_{p^2}$ with $j(E)\notin \{0,1728\}$, consider an endomorphism $\hat{I}\pm$ of $E$ represented as a…
