New IP for standards-compliant Car2Infrastructure and Car2Car communications

LinkedIn +

EnSilica, a provider of semiconductor solutions and IP, has launched the eSi-ECDSA cryptographic IP, which has been designed to help meet the high security communication and latency requirements of automotive Car2Car (C2C) and Car2Infrastructure (C2X) applications that form part of intelligent transport systems.

EnSilica’s eSi-ECDSA cryptographic IP is fully compliant with the IEEE 1609.2 and ETSI TS 103 97 standards. These standards define the security layers in the Car2x communication protocols where cryptographic algorithms are the primary tools used to safeguard against information security risks such as message confidentiality, integrity, availability and authenticity. In particular, the elliptic curve digital signature algorithm (ECDSA) is specified for message authentication, the elliptic curve integrated encryption scheme (ECIES) for asymmetric encryption, and the advanced encryption standard (AES) for symmetric encryption.

EnSilica’s eSi-ECDSA is an ASIC acceleration core that has been specifically designed to deliver the high level of message-signature verifications required by Car2x ECDSA message authentication, where practical requirements range between 400 and 4,000 verifications per second depending on the message beaconing rate (1Hz to 10Hz) and expected worst case vehicle densities on the road.
