SmartCAN
The SmartCAN protocol augments existing CAN with higher speed data and provides bus guarding support to stop spoofing and denial-of-service attacks. Most importantly, SmartCAN interoperates completely with existing CAN systems. The SmartCAN engine is a Verilog hardware IP module that can transmit and receive CAN frames, both as pure CAN and as classic CAN frames augmented with a security header and an optional payload body (up to 276 bytes on a 250kbit/sec classic CAN bus). It is used inside the Canis Labs IDPS100 module.
IDPS100
The Canis IDPS100 is a Verilog hardware IP module for CAN bus intrusion detection and prevention (IDPS), used in the Siemens Secure-CAV Embedded Analytics platform. It supports the SmartCAN augmentation of the CAN 2.0 protocol and can read security headers for hardware anti-spoofing. It can destroy unauthorized or spoof frames before they are received and has support for sending classic CAN frames augmented with SmartCAN information, including large payloads (276 bytes inside a 250kbit/sec classic CAN 8 byte frame).
Bus Guardian
In aftermarket situations when cybersecurity and/or increased bandwidth are required but replacing all ECU's in a vehicle is not feasible, a tiny Bus Guardian can be added to critical ECU's in that will both speed up communications by an order of magnitude and protect it from cyberthreats. The remaining ECU's will operate normally without noticing the extra data on the Bus Guardian enhanced ECU's.
The Bus Guardian is a tiny chip that gets added to relevant ECU's that require protection.
