A method and apparatus for binding update between a mobile node and a correspondent node is disclosed. The method includes: encrypting, by the correspondent node, a parameter for generating a binding management key with a key, and transmitting the encrypted parameter to the mobile node or a home agent which performs binding update on behalf of the mobile node; obtaining, by the mobile node or the home agent, the parameter via decryption, generating a binding management key with the parameter, generating authentication data with the binding management key, and transmitting a binding update message carrying the authentication data to the correspondent node; and verifying, by the correspondent node, the binding update message based on the authentication data, and returning a binding acknowledgement message to the mobile node or the home agent. With the present invention, the security of the binding update process may be improved. |
