Techniques include a first electronic control unit (ECU) receiving a synchronization message including a trip counter and receiving a message from a second ECU including a trip flag. The trip flag includes a single bit of data generated by the second ECU. The first ECU compares the trip flag to a last bit of the trip counter stored at the first electronic control unit and processes the message in response to the trip flag matching the trip counter. The first ECU compares the trip counter to a previous trip counter based on the trip flag differing from the trip counter. The first ECU processes the message using the previous trip counter or increments the trip counter to process the message based on the comparison with the previous trip counter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting and resolving desynchronization of trip counter values in authenticated messages","description":"Techniques for using a trip flag to detect desynchronization of trip counter values in a vehicle system.
