ABSTRACT:
Methods and apparatus for dynamically generating authentication keys are disclosed. Specifically, a Mobile-Foreign authentication key is separately generated by both the Mobile Node and Foreign Agent. Similarly, a Foreign-Home authentication key is separately generated by the Foreign Agent and the Home Agent. In accordance with one embodiment, generation of the Mobile-Foreign authentication key and Foreign-Home authentication key are accomplished via the Diffie-Hellman key generation scheme.
