IPC: G06F21/64
Filed: 2006-01-18
Abstract: Accelerated computation of combinations of group operations in a finite field is provided by arranging for at least one of the operands to have a relatively small bit length. In a elliptic curve group, verification that a value representative of a point R corresponds the sum of two other points uG and vG is obtained by deriving integers w,z of reduced bit length and so that v = w/z. The verification equality R = uG + vQ may then be computed as -zR +(uz mod n) G + wQ = O with z and w of reduced bit length. This is beneficial in digital signature verification where increased verification can be attained.
