Abstract:
1. A method comprising: selecting an elliptic curve; determining a Squared Weil pairing based on the elliptic curve, wherein the elliptic curve includes an elliptic curve E over a field K, wherein E can be represented as an equation y wherein determining the Squared Weil pairing based on the elliptic curve further includes establishing a point id that is defined as a point at infinity on E, and wherein P, Q, R, X are points on E wherein X is an indeterminate denoting an independent variable of a function, and wherein x(X), y(X) are functions mapping the point X on E to its affine x and y coordinates, and wherein a line passes through the points P, Q, R if P+Q+R=id; wherein determining the Squared Weil pairing based on the elliptic curve further includes: with a first function ƒ cryptographically processing selected information based on the Squared Weil pairing; outputting validation of selected information based on the Squared Weir pairing; and determining a course of action in response to validation of selected information.
