We give an algorithm that constructs, on input of a prime power q and an integer t, a supersingular elliptic curve over Fq with trace of Frobenius t in case such a curve exists. If …

In this paper, we study several related computational problems for supersingular elliptic curves, their isogeny graphs, and their endomorphism rings. We prove reductions between …
We consider the problem of sampling random supersingular elliptic curves over finite fields of cryptographic size (SRS problem). The currently best-known method combines the …

An important open problem in supersingular isogeny-based cryptography is to produce, without a trusted authority, concrete examples of 'hard supersingular curves' that is …
We introduce a special class of supersingular curves over 𝔽 p 2, characterized by the existence of noninteger endomorphisms of small degree. We prove a number of properties …
Abstract Let ℰ∕ 𝔽 q be an elliptic curve, and P a point in ℰ (𝔽 q) of prime order ℓ. Vélu's formulæ let us compute a quotient curve ℰ′= ℰ∕⟨ P⟩ and rational maps defining a …
In this paper, we introduce a polynomial-time algorithm to compute a connecting O O-ideal between two supersingular elliptic curves over F _p F p with common F _p F p …
