Abstract: A gateway apparatus supports differentiated secure communications among heterogeneous electronic devices. A communication port communicates via communication networks of different types with two or more associated devices having diverse secure communication capabilities. The gateway logic selectively authenticates the associated devices for group membership into a Secure Communication Group (SCG), and selectively communicates Secure Communication Group Keys (SCGKs) to the devices having the diverse secure communication capabilities for selectively generating session keys locally by the associated devices for mutual secure communication in accordance with the group membership of the associated devices in the SCG.

Abstract: Apparatus, methods and logic for vehicles to determine vehicle to vehicle (V2V) safety message transmission rates for transmitting V2V safety messages based on how frequently the vehicles actually need to exchange safety messages, including factors such as vehicle velocities, distances among vehicles, and on how quickly the inter-vehicle distances are closing up. The determined V2V safety message transmission rates are selectively dynamically adjusted in accordance with detected significant changes in one or more of the inter-vehicle distances or inter-vehicle speeds. To avoid needless frequent changes to the transmission rate, statistical modeling techniques including hypothesis testing and sequential change detection are selectively used to more accurately detect significant changes in inter-vehicle distances or inter-vehicle speeds that warrant a change to the message transmission rate.
Abstract translation: 根据车辆实际需要交换安全信息的频率，确定车辆与车辆（V2V）安全信息传输速度的装置，方法和逻辑（V2V），用于传输V2V安全信息，包括车辆速度，车辆距离和 车辆间距离关闭多快。 所确定的V2V安全消息传输速率根据车辆间距离或车间速度中的一个或多个中检测到的显着变化而被选择性地动态地调节。 为了避免不必要地频繁地改变传输速率，选择性地使用包括假设测试和顺序改变检测在内的统计建模技术来更准确地检测车辆间距离或车辆间车辆速度的显着变化，这样可以改变消息传输速率。

Abstract: The trustworthiness of vehicle-to-vehicle (V2V) messages received from one or more associated vehicles in the vicinity of a subject vehicle is determined autonomously by a false signal detection system of the subject vehicle. Physical evidence relating to the associated vehicles is collected, and a statistical model is used to perform an analysis of the collected data. A V2V message is received by the system from a first one of the associated vehicles and a trustworthiness level of the message is determined in accordance with a correlation between the received V2V message and the result of the analyzed physical data relating to the first associated vehicle. The correlation may be a comparison of data contained in the received V2V message relative to a result of a stochastic analysis of the physical data. The received V2V message may be any V2V safety message including Emergency Electronic Brake Light (EEBL) messages.

Abstract: A system authenticates in-vehicle electronic devices having unequal capabilities such as having varying different communication and processing capabilities. A Connected Vehicle Gateway portion of a selected in-vehicle device acts as an onboard authentication proxy and onboard key server functionality for other in-vehicle devices, and serves as an interface between an in-vehicle network and one or more associated external networks, thereby eliminating the need for explicit peer discovery protocol and the requirement of devices to perform key establishment with each individual communication peer. Instead, each in-vehicle device establishes the group keys as a result of its authentication with the onboard key server and uses the group keys to locally generate and update its session keys. The onboard key server selectively obtains the keys from one or more off-board authentication servers and distributes them to selected in-vehicle devices.
