Protection of Binding Update Message in Mobile IPv6

Mobile Nodes (MN) in Mobile IPv6 (MIPv6) are given the opportunity to eliminate triangle routing that is inefficient with their own corresponding node (CN) using Route Optimisation (RO). This greatly improves the performance of the network. Unfortunately, using this method allows several security vulnerabilities to manifest itself with the MIPv6. Among those, common issues are those concerns the verification of authenticity and authorisation of Binding Updates during the process of RO. These types of unauthenticated and unauthorised BUs are the key to various types of malicious attacks. Since it is expected that MIPv6 will be supported by IPv6, several mechanism to ensure BU security will be crucial in the next generation Internet. This article focuses on Mobile IPv6 and security considerations.
