CAN Transceivers with cyber security functions: NXP, the market-leading CAN transceiver manufacturer, has introduced ideas to secure the CAN lower layers that can be implemented in smart CAN transceivers

摘要

The modern connected car with various internal and external communication interfaces, up to 150 electronic control units (ECUs) and 100 million lines of code, is a cyber-physical system rather than a simple mechanical system. One challenge of seamless connectivity to the Internet and end-user devices is the exposure of the vehicle to malicious exploitation of vulnerabilities, such as buffer overflow exploits, malware and Trojans. The connected car's potential for attack (its "attack surface") is increasing as the amount of connectivity, electronics and software continues to increase.
