In mobile IPv6, the location of a mobile node (MN) is obtained by implementing a binding update (BU) process. During the process, the unauthenticated BU message may give rise to many security risks, such as denial-of-service (DoS) attack. Thus, authentication of the BU message is most important for the security of mobile IPv6. The purpose of cryptographically generated addresses (CGA) is to prevent stealing and spoofing of existent IP addresses. In this paper, a novel authentication mechanism based on CGA is proposed for BU message in mobile IPv6. With the implementation of the novel authentication mechanism, care-of address of MN will be automatically generated, and this will be related to MN private attribute, hence, it would not be possible for a vicious node to steal it. With this method, the BU message can be authenticated.
