Fast repeated doublings in elliptic curves of characteristic 2

Speaker: Daniel Sutantyo
Date, Time: Fri, 10 Aug 2012 14:30

We introduce a new operation called half-doubling which can be used to compute [2^k]P efficiently on elliptic curves defined on binary fields. For curves in Weierstrass form using Lopez-Dahab coordinates, this operation is faster than the standard doubling formula, at the cost of some precomputations. We then show how the scalar multiplication operation on these curves can be sped up using this operation.
