Title:
ZERO KNOWLEDGE PROOF HARDWARE ACCELERATOR AND THE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/164047
Kind Code:
A1
Abstract:
A hardware accelerator for accelerating the zk-SNARK protocol by reducing the computation time of the cryptographic verification is disclosed. The accelerator includes a zk-SNARK engine having one or more processing units running in parallel. The processing unit can include one or more multiply-accumulate operation (MAC) units, one or more fast Fourier transform (FFT) units; and one or more elliptic curve processor (ECP) units. The one or more ECP units are configured to reduce a bit-length of a scalar d i in an ECP algorithm used for generating a proof, thereby the cryptographic verification requires less computation power.
