Ed3363 (HighFive) -- An alternative Elliptic Curve

Mike Scott

Abstract: We propose a new Elliptic curve at a security level significantly greater than the standard 128 bits, that fills a gap in current proposals while bucking the expected security vs cost curve by exploiting the new trick recently described by Granger and Scott. This essentially reduces the cost of field multiplication to that of a field squaring.
