    摘要： A method for determining whether to perform vertical handoff between multiple network. The method comprises obtaining a plurality of selection metrics for each network, calculating, for each of the other communication networks, a predicted utility value from at least the corresponding plurality of selection metrics using a variable kernel regression function, obtaining, for the current communication network, a second plurality of selection metrics; calculating a second predicted utility value for the current communication network from at least the corresponding second plurality of selection metrics using a second variable kernel regression function, comparing each of the predicted utility values for each of the plurality of other communication networks with the second predicted utility value and switching to one of the other communication networks having the highest predicted utility value, if the highest predicted utility value is greater than the second predicted utility value.

    摘要： A method and system for public key infrastructure key and certificate management provides anonymity to certificate holders and protects the privacy of certificate holders from the compromise of a certificate authority. Functional separation is provided in the authorization of a certificate request and the assignment of certificates and key pairs. The authorizing certificate authority approves or denies each certificate request from a requestor whose identity is not made available to the assigning certificate authority. The assigning certificate authority, upon approval from the authorizing certificate authority, issues one or more certificates and optionally generates and provides the associated key pairs to the requester without disclosing these certificates and key pairs to the authorizing certificate authority. In another aspect, a distributed method is disclosed that allows individual nodes and/or units in a network to select certificates for broadcasting messages to a community of interest with a non-unique key.

    摘要： The present invention advantageously provides techniques to solve problems with combinatorial anonymous certificate management by addressing critical issues concerning its feasibility, scalability, and performance. Methods and procedures to manage IEEE 1609.2 anonymous and identifying cryptographic keys and certificates in the Vehicle Infrastructure Integration (VII) system are presented, along with methods for management of identifying and anonymous certificates in a partitioned Certificate Authority architecture designed to enhance vehicle privacy. Novel methods for vehicles to dynamically change an anonymous certificate for use while maintaining vehicle privacy are given. Refinements to basic combinatorial schemes are presented including probabilistic key replacement, rekey counter decrement, dynamic rekey threshold, geographic attack isolation and proofs of geographic position.
