20170374085 · 2017-12-28 ·

The invention discloses a method for deep data inspection over an industrial internet field broadband bus, the method including: obtaining, by a first node, a message to be transmitted; judging, by the first node, whether a bus device address in the message to be transmitted lies in a preset range of bus device addresses; and if the bus device address lies in the preset range of bus device addresses, then transmitting, by the first node, the message to be transmitted to a processor of the first node. The first node only forwards the message to be transmitted, lying in the preset range of bus device addresses to thereby improve the security of transmitting the message.

11689434 · 2023-06-27 · ·

An anomaly detector of a Controller Area Network (CAN) bus performs analysis on messages received from the CAN bus to determine if the messages are anomalous. The anomaly detector may be implemented on a vehicle by an Electronic Control Unit (ECU). The anomaly detector may extract a batch of feature vectors for binary messages received from the CAN bus. The anomaly detector then performs a model adaption to adapt a previous probability model with the batch of feature vectors. The adapted probability model is then compared with a universal background model to determine a network anomaly level.
