Abstract: Elliptic curve cryptosystems are usually implemented over elds of characteristic two or over (large) prime elds. For large prime elds, projective coordinates are more suitable as they reduce the computational workload in a point multiplication. In this case, choosing for parameter a the value 3 further reduces the workload. Over Fp , not all elliptic curves can be rescaled through isomorphisms to the case a = 3. (Update)
