<p>A protection method for a mobile IPv6 fast handover is provided, which includes the following steps: generating a fast-handover signaling protection key by using a key which is shared with a network side device; generating an authentication code according to the protection key; adding the authentication code to the fast-handover signaling and transmitting the fast-handover signaling to a router. A protection device for a mobile IPv6 fast handover is also provided. By using the method, the shared key between the mobile node and the network side device is used to derive the fast-handover signaling protection key to protect the fast-handover signaling, which solves the security problem of the fast-handover message during a mobile IPv6 fast handover, decreases overhead during storing and calculating regarding the mobile node, and can be used to protect the downward fast-handover signaling of the SeND protocol that cannot be supported by the mobile node.</p> |
