摘要： A method is provided for obtaining a certificate revocation list (CRL) for a vehicle in a vehicle-to-vehicle communication system. A portable security unit is provided to access secured operations for the vehicle. The portable security unit is linked to a device having access to a communication network. The communication network is in communication with a certificate authority for issuing an updated CRL. The updated CRL is downloaded from the certificate authority to the portable security unit. At a later time, when a user enters the vehicle, a communication link is established between the portable security unit and a vehicle processor unit. Mutual authentication is exchanged between the portable security unit and the vehicle processing unit. The updated CRL stored in the portable security unit is downloaded to a memory of the vehicle communication system in response to a successful mutual authentication.

摘要： A computationally efficient message verification strategy that achieves non-repudiation and resilience to computational denial of service attacks in conjunction with a broadcast authentication protocol that authenticates messages using a combination of a digital signature and a TESLA MAC. When messages are received at a receiver, the verification strategy separates the messages into messages with the same sender identification. The strategy then determines whether the TESLA MAC authenticator is valid for each message and discards those messages that do not have a valid TESLA MAC. The strategy collects the messages that have a valid TESLA MAC for each sender identification and performs a batch verification process on the group of messages to determine if the messages in the group have a valid digital signature. This strategy verifies each message in the group of messages if the batch verification process shows that the group of messages has a valid digital signature.

摘要： A packet processing framework is provided for a vehicle-to-vehicle communication packet processing system. The framework includes a neighborhood vehicle tracking module for tracking neighboring vehicles relative to a host vehicle. The neighborhood vehicle tracking module assigns a priority level of neighboring vehicles relative to a host vehicle. An adaptive security processing module regulates messages streamed to the neighboring vehicle tracker module that are in accordance with the priorities set forth by the neighborhood vehicle tracking module. The adaptive security processing module selects security modes and schedules messages streamed to the neighborhood vehicle tracking module as a function of priorities set forth by the neighborhood vehicle tracking module, a communication reliability of the transmitting neighboring vehicle, and a likelihood that a message from the neighboring vehicle is genuine as determined by the adaptive security processing module. The neighborhood vehicle tracking module outputs processed kinematics and alert information to at least one vehicle-to-vehicle application.

摘要： A method is provided for processing packets in a security module of a node in a real-time tracking system. The security module receives messages via a communication module. Each message contains an identifier associated with a transmitting entity of the message. A respective identifier is associated with a respective buffer. Messages having a same identifier are stored to an associated buffer. At least one message is selected from each buffer. For each buffer, a verification mode is selected for the message selected based on state variables and identifier-level properties of the identifier associated with that buffer. A buffer for message verification is selected based on state variables and identifier-level properties of all identifiers. The message selected is verified utilizing the selected verification mode. The state variables and the identifier-level properties of all identifiers are updated based on a result of the verification of the at least one message.
