Panasonic had 116 patents in cybersecurity during Q3 2023. Panasonic Holdings Corp filed patents in Q3 2023 for various technologies. One patent is for a method to determine continuity between vehicle attack events in an in-vehicle network. Another patent is for a management device that verifies and stores operation logs for analyzing anomalies. An information processing device patent involves determining the occurrence time and expected end time of network attacks based on detection logs. Additionally, there are patents related to transmitting vehicular data via a sidelink interface with autonomous radio resource allocation, and configuring communication periods in a mobile terminal based on a discontinuous reception cycle.

Application: Vehicle attack event continuity determination method, vehicle attack event continuity determination device, and non-transitory computer-readable recording medium (Patent ID: US20230269258A1)
The patent filed by Panasonic Holdings Corp. describes a method and device for determining the continuity of vehicle attack events in an in-vehicle network. The method involves obtaining information about multiple vehicle attack events, the configuration of the in-vehicle network, and vehicle function events. Based on this information, the method determines whether there is continuity between the attack events and outputs the result of the determination.
The method includes obtaining information about the first and second vehicle attack events that have occurred in the in-vehicle network, as well as the configuration of the network. It then determines whether there is continuity between these attack events based on the obtained information. If there is no continuity between the first and second attack events, the method further obtains information about a third vehicle attack event that occurred before the second event and determines whether there is continuity between the first attack event and the third attack event. The method takes into account the anomaly detectors in the in-vehicle network and calculates the attack path and non-detecting anomaly detectors to determine continuity.
The method also considers vehicle function events and their usage rate to determine continuity. It obtains information about vehicle function events that have occurred in the vehicle and calculates the usage rate based on the occurrence of these events within a predetermined period. The method updates the predetermined period based on the usage rate and determines continuity using the updated period.
The method further includes merging the first and second vehicle attack events when continuity is determined. It calculates the reliability level of the merged attack event based on the information obtained about the first and second attack events and outputs the reliability level.
The patent also describes a device for implementing the method and a computer-readable recording medium containing a program for executing the vehicle attack event continuity determination processing.
In summary, the patent filed by Panasonic Holdings Corp. presents a method and device for determining the continuity of vehicle attack events in an in-vehicle network. The method considers multiple attack events, the configuration of the network, and vehicle function events to determine continuity and outputs the result of the determination.
