    Abstract: A computer-implemented method may include obtaining, from a system using a middleware component of the system, run-time evidence of the system; applying the obtained run-time evidence to a Directed Acyclic Graph (DAG) Bayesian network to determine marginal probabilities for one or more nodes of the DAG Bayesian network, wherein the DAG Bayesian network comprises a plurality of nodes each representing states and faults of the system, wherein each node includes a parameterized conditional probability distribution, and wherein one or more of the nodes of the plurality of nodes specify a list of one or more safety goals and a safety value; determining which nodes representing faults have probabilities exceeding their specified safety value; and determining one or more risk mitigation techniques to activate for the determined nodes representing faults with probabilities exceeding their respective safety value.

    Abstract: V2X trusted agents provide technical solutions for technical problems facing falsely reported locations of connected vehicles within V2X systems. These trusted agents (e.g., trusted members) may be used to detect an abrupt physical attenuation of a wireless signal and determine whether the attenuation was caused by signal occlusion caused by the presence of an untrusted vehicle or other untrusted object. When the untrusted vehicle is sending a message received by trusted agents, these temporary occlusions allow trusted members to collaboratively estimate the positions of untrusted vehicles in the shared network, and to detect misbehavior by associating the untrusted vehicle with reported positions. Trusted agents may also be used to pinpoint specific mobile targets. Information about one or more untrusted vehicles may be aggregated and distributed as a service.

    Abstract: An apparatus, including: an interface operable to receive real-time information related to one or more actors in a real environment; and processing circuitry operable to: generate a digital twin of the real environment, wherein the digital twin is a virtual representation of the real environment; spawn a model that mirrors the one or more actors based on the real-time information; and generate a spatial sound signal based on the digital twin for transmission to an ego actor of the one or more actors in the real environment, wherein the generation of the spatial sound signal comprises generating the spatial sound signal to be individualized from an auditory perspective of the ego actor in the real environment to originate from a source actor of the one or more actors.

    Abstract: Systems and techniques for securing vehicle privacy in a driving infrastructure are described herein. A vehicle may contact a group identification (ID) issuer to register itself. A group ID may be received from the group ID issuer to indicate acceptance as a member. The vehicle may then contact the driving infrastructure to attach to the driving infrastructure using the group ID to identify the vehicle. In response, the vehicle receives an attachment ID from the driving infrastructure. Here, the attachment ID is used to secure communications between the vehicle and the driving infrastructure.
