ALEXANDRIA, Va., Sept. 1 -- United States Patent no. 12,726,332, issued on Sept. 1, was assigned to Trustees of Boston University (Boston).

"Semi-custom accelerator device for bootstrappable fully homomorphic encryption" was invented by Rashmi S. Agrawal (Cambridge, Mass.) and Ajay J. Joshi (Lexington, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "An FPGA-based accelerator for bootstrappable fully homomorphic encryption (FHE) employs (1) acceleration of scalar arithmetic operations using a multi-word approach for efficient utilization of standard-width components (multipliers/adders) on custom-width operands; (2) a performant, shift-based modular reduction technique that avoids the need for expensive ...
