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.

Abstract: Disclosed is a processor for processing data from a buffer memory. The processor, 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.

Abstract: Un metodo y sistema para la determinacion de latencia de enlace en una red de IP Movil determinan un retraso de red no cargado; establecer un retraso calculado actual; iniciar un proceso de calculo de viaje redondo actual; y establecer un temporizador de reintento. Si el temporizador de reintento expira antes de que termine el proceso el metodo y sistema actualizan el periodo de espera predeterminado y repiten los dos pasos anteriores. Despues del re-registro, el metodo y sistema reestablecen la hora de retraso calculado actual. La determinacion de latencia de enlace optimiza el proceso de re-registro entre un dispositivo movil y un dispositivo de agente, mejorando consecuentemente las comunicaciones de dispositivo movil, minimizando la carga de red, y optimizando los niveles de trafico de red.
