Abstract:

In order to realize the commercial deployment of the mobile IP, AAA (Authentication, Authorization, Accounting) is introduced into mobile IP registration. Aimed at the security and efficiency problems of the registration, a mobile IP registration protocol with AAA is proposed based on pairing-free certificateless public key cryptography. The mutual authentications between AAAF (AAA server in Foreign networks) and AAAH (AAA server in Home networks) are achieved by using a strongly secure and efficient certificateless signature scheme without pairings; the authentication of AAAH to MN (Mobile Node) and that of MN to HA (Home Agent) are realized via the MAC (Message Authentication Code). The user anonymity is achieved via the dynamic TID (Temporary Identity) instread of the user's account information of the NAI (Network Access Identifier). Theoretical analyses show that the protocol reaches the expected security goals. Compared with the protocol proposed by Cao et al., the protocol reduces the registration delay about 20% while improving the security.

Key words: mobile IP, certificateless signature, authentication, authorization, accounting(AAA), registration
