Abstract

We introduce a new hierarchical key management scheme which can be applied for secure Mobile IP registration protocol. Contrary to the previous schemes, AAA protocol used for registration key distribution is separated from the base registration protocol, so that the registration key distribution can be simplified and the delay caused by the AAA protocol can be avoided. Also proposed is the non-repudiation service based on a hash chain, which is useful for secure auditing.
