  • Patent number: 9836414
    Abstract: A processor for processing data from a buffer memory, implemented in hardware, may allow writing of output data, processed based on input data from at least one secure location associated with a secure address range of the buffer memory, to one or more secure locations associated with the secure address range. Further, the processor may block writing of output data, processed based on input data from at least one secure location associated with the secure address range, to one or more insecure locations associated with an insecure address range of the buffer memory.
    Type: Grant

  • Patent number: 8195940
    Abstract: This disclosure describes a key update scheme for use in a mobile IP network. The update scheme may be implemented to facilitate key updates between a mobile device and a server computer that authenticates the mobile device. The techniques described herein can facilitate key updates in a manner that accounts for potential message loss during the update routine, mobile device failure during the update routine, or other problems typically encountered in a mobile network settings. In this manner, the techniques can provide a robust scheme for key updates and may improve network security.

  • Patent number: 7796582
    Abstract: Methods and apparatus are presented herein for allowing a keyless access terminal (AT) to access a packet serving data node (PSDN) over a service network stream without deactivating the authentication functions of the authentication network stream.

  • Patent number: 7710905
    Abstract: A method and system for link latency determination in a Mobile IP network determine an unloaded network delay; set a current estimated delay; initiate a current round trip estimation process; and set a retry timer. If the retry timer expires before the process completes, the method and system update the predetermined backoff period and repeat the preceding two steps. After re-registration, the method and system reset the current estimated delay time. The link latency determination optimizes the re-registration process between a mobile device and an agent device, thereby enhancing mobile device communications, minimizing network loading, and optimizing network traffic levels.
