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: 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.
