CM LIFTINGS OF SUPERSINGULAR ELLIPTIC CURVES
, 2009
"... Assuming GRH, we present an algorithm which inputs a prime p and outputs the set of fundamental discriminants D < 0 such that the reduction map modulo a prime above p from elliptic curves with CM by OD to supersingular elliptic curves in characteristic p. In the algorithm we first determine an e ..."

MINIMAL CM LIFTINGS OF SUPERSINGULAR ELLIPTIC CURVES
"... Abstract. In this paper, we give a ‘direct ’ construction of the endomorphism ring of supersingular elliptic curves over a prime field Fp from ‘ideal classes ’ of Q( √−p). We use the result to prove that the result of Kaneko on ‘minimal ’ CM liftings of such supersingular elliptic curves is a best p ..."

On a certain supersingular elliptic curve
, 2001
"... In this note, by means of determination of the number of rational points, it is shown that if F is a finite prime field of characteristic p satisfying p 5 (mod 8) then the elliptic curve y2 =X (X 2+X + r) defined over F is supersingular where r = 1/8 E F. As an application, it is also shown that th ..."

SUPERSINGULAR ELLIPTIC CURVES AND MAXIMAL QUATERNIONIC ORDERS
"... Abstract. We give an explicit version of the “Deuring correspondence ” between supersingular elliptic curves and maximal quaternionic orders, by presenting a deterministic and explicit algorithm to compute it. In this talk all fields of positive characteristic will be either finite or function field ..."

Explicit Generators for Endomorphism Rings of Supersingular Elliptic Curves
, 2004
"... Let p be a prime, and let E/Fp2 be a supersingular elliptic curve. Then it is straightforward to show that EndF̄p(E) is isomorphic to a maximal order within Qp,∞, the unique quaternion algebra ramified precisely at p and ∞. In fact, it is a wellknown result of Deuring that this defines a 1: 1 corre ..."

Evidence that XTR is more secure than supersingular elliptic curve cryptosystems

, 2001
"... Abstract. We show that finding an efficiently computable injective homomorphism from the XTR subgroup into the group of points over GF(p 2) of a particular type of supersingular elliptic curve is at least as hard as solving the DiffieHellman problem in the XTR subgroup. This provides strong evidenc ..."
