  • Elliptic curve encryption systems
    Patent number: 6618483
    Abstract: An elliptic curve encryption system represents coordinates of a point on the curve as a vector of binary digits in a normal basis representation in F2m. A key is generated from multiple additions of one or more points in a finite field. Inverses of values are computed using a finite field multiplier and successive exponentiations. A key is represented as the coordinates of a point on the curve and key transfer may be accomplished with the transmission of only one coordinate and identifying information of the second. An encryption protocol using one of the coordinates and a further function of that coordinate is also described.
