- Abstract
- The Mobile IP application of AAA (Diameter protocol) provides authentication, authorization, and accounting (AAA) services to a mobile ISP network for achieving legitimate mobility using e-mail-styled NAI and MAC valued keys in wireless IP access. In the rapidly expanding mobile environment, the introduction of identity-based cryptographic schemes has many advantages ranging from easy migration to public key cryptography. Accordingly, the current paper proposes a secure wireless Internet roaming service and WLAN service using identity(ID)-based cryptography. To support secure Mobile IP authentication between a mobile node and the authentication server, Mobile IP with an AAA protocol of mutual authentication is proposed using an ID-based signature scheme instead of a conventional MAC valued, symmetric, and single authentic protocol. Furthermore, the proposed protocol can also be implemented using algorithms based on elliptic curves.
