METHOD TO REDUCE THE LATENCY OF ECDSA SIGNATURE GENERATION USING PRECOMPUTATION

摘要

In order to reduce latency of elliptical curve digital signature generation a portion of the digital signature is pre-calculated before receipt of the message hash using an unmodified ECDSA computing engine. After the message hash is received, the digital signature is completed without using the ECDSA computing engine. Applications include generating digital signatures for the safety messages in Intelligent Transport Systems.

1. A method to reduce the latency of elliptical curve digital signature generation using pre-computation comprising:
pre-computing an incomplete elliptical curve digital signature using an ECDSA computing engine prior to a receipt of a message hash; and completing computation of an elliptical curve digital signature without using the ECDSA computing engine after receipt of the message hash by using the incomplete elliptical curve digital signature as input.
