Abstract
Methods and apparatus for dynamically generating a set of Mobile IP keys are disclosed. The set of Mobile IP keys is dynamically generated using an existing HLR/AuC authentication infrastructure. This is accomplished, in part, by obtaining an International Mobile Subscriber Identity (IMSI) that uniquely identifies a particular Mobile Node. Once a set of Mobile IP keys is generated from authentication information associated with the IMSI, the Mobile Node may register with its Home Agent using the set of Mobile IP keys.
