ALEXANDRIA, Va., Sept. 8 -- United States Patent no. 12,732,365, issued on Sept. 8, was assigned to Synopsys Inc. (Sunnyvale, Calif.).

"Adding scalar blinding in elliptic curve cryptography" was invented by A. A. Jithra Adikari (Ottawa) and Rudolphus J. C. Derwig (Eindhoven, Netherlands).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method of performing elliptic curve cryptography includes, in part, receiving a scalar k representative of a secret key; and splitting, by a processing device, a multiplication of k by a generator point P on the elliptic curve ([k]P) into a sum of a first multiplication defined by [k-r]P, and a second multiplication defined by [r/n](nP), where n is a power of 2 of an integer nu...
