  • Patent number: 9497768
    Abstract: A method of dynamic adjusting a generation frequency of messages in vehicular networks is provided, including: receiving updating requests and emergent degree of the vehicle event, and then determining whether the generation frequency of messages meets the dynamic change of the vehicle, if not satisfied, selecting a different adjustment method according to the event emergent degree. When the event is emergent, its generation frequency can be raised immediately by an interruptive adjustment and to suppress the generation frequency of messages of the others. Conversely, adjusting its generation frequency by a progressive adjustment and reducing the generation frequency of messages of the other lower-priority vehicles. According to the present disclosure, it prevents lower priority messages from occupying the channel overly, and emergency messages with higher priority can be satisfied immediately when it needed.

  • Patent number: 9425967
    Abstract: Embodiments of the present invention are directed to methods and systems for generating and revoking, as well as validating, certificates used to protect communications within networks while maintaining privacy protection. In the context of a method, certificate generation and revocation with privacy preservation comprises determining a secret value to be used by a certificate authority and an entity; constructing a key tree based on the secret value, wherein the leaves of the key tree represent derived keys for the certificates for the entity; and generating certificates for the entity based in part on the key tree leaves. The method further comprises determining that one or more of the certificates should be revoked; determining a minimum key node set that covers the certificates to be revoked; adding the minimum key node set to a certificate revocation list; and providing the certificate revocation list to one or more entities. Corresponding apparatuses and computer program products are also provided.

  • Patent number: 7817644
    Abstract: Methods and apparatus for an ATM network for implementing a fair servicing of all connections during a back-logged condition through the use of a weighted fair queuing technique. The system is particularly suited for systems where the packets/cells are of a fixed size. Although some important approximations are made in the proposed implementation, all of the properties of an ideal weighted fair queuing algorithm are preserved. The sorting methods and apparatus are advantageous in that it is possible to maintain appropriate servicing of connections without sorting all of the individual connections. This may be accomplished by pre-sorting each of the individual virtual circuit connections into a finite number of predetermined bins according to a weight associated with the connection. Thereafter, only the bins need be sorted without having to sort each of the individual connections.
