Latest Patents
One of Crandall's latest patents is a method and apparatus for digital signature authentication. This invention enhances speed and reduces complexity in a digital signature scheme that utilizes elliptic algebra. The signature scheme generates two points that are compared to verify authenticity. If the points do not match, the signature is deemed not authentic. By comparing only the x-coordinates of the two generated points, the present invention significantly reduces computational requirements. Furthermore, it provides a scheme for deducing possible values of the x-coordinate of a sum of two points using only the x-coordinates of the original two points. This innovation limits the possible solutions to two: the authentic signature and one other. Due to the vast number of potential inauthentic solutions, the likelihood of a false authentic signature is statistically insignificant.
