Enhancing SVO Logic for Mobile IPv6 Security Protocols
Mobile IPv6 (MIPv6) is one key protocol for IPv6 enabled computers and handsets providing always-on capabilities and seamless mobility between wireless and wired networks. Binding Update protocol, which has resolved the triangle routing problem in MIPv6, was fraught with vulnerabilities due to mobility. In this paper, we presented three typical lightweight unilateral authentication protocols for securing Binding Update, and compared their security features. We proposed one approach based on BAN logic, a famous formal method has been successfully used in several projects, with extended rules and definitions that are capable of specifying security properties and goals of these protocols. Finally, and the effectiveness of this approach was demonstrated. We hope these works can contribute to the ongoing design and deployment of MIPv6 and pave the way for future research in the security evaluation of MIPv6.
