Zusammenfassung: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.
