Cars Get Secure CAN Communications Without Cryptography

NXP is boosting cybersecurity in today’s complex car networks with a new secure CAN transceiver that secures CAN communications without requiring software or cryptography.

NXP transceiver-based solution for the CAN network provides security – with no additional bandwidth requirements, no delays and no additional processor load, NXP claims.

This novel approach complements crypto-based security solutions with an additional layer in a Defense-in-Depth (DiD) concept, or as a standalone option.

“CAN networks are used in every car to connect electronic control units (ECUs) and are expected to remain the dominant network for the next decade. As automotive electronic content continues to rise, the amount of real-time data exchanged across CAN networks will increase.”

“Security solutions available today protect CAN communication with message authentication code (MAC) based on cryptography and complex key management, that require increased CAN bus load, message latency and computing power consumption.”

NXP notes that upgrading existing ECU designs to support secure CAN messages will require processors with sufficient compute power.

Another simpler, faster way to secure messages from the existing ECUs is with use of secure CAN transceivers, which will turn them into secure ECUs, explained the company.

NXP said its new transceiver-based solution for the CAN network provides security – with no additional bandwidth requirements, no delays and no additional processor load.
