The ubiquity of the Internet and explosive growth in wireless networking in recent years increasingly urge the demand to support mobility within the Internet, which is what Mobile IP aims to provide. This paper is concerned with the security aspect of the registration protocol in Mobile IP. The paper shows that despite the use of authenticated registration messages and replay protection, the current registration protocol differs from a possible replay attack. The paper also analyzes a proposed extension of Mobile IP that aims to provide public-key based authentication. It shows some drawbacks in the protocol design and then proposes a new secure authentication protocol that employs only minimal use of public key cryptography. Despite its practicality, the new protocol provides a scalable solution for authentication and non-repudiation, while sets only minimal computing and administration cost on the mobile node
