Abstract
A system and method are disclosed for securing binding updates in a wireless telecommunications system. A public key is generating using a home address value of the mobile host. Thereafter, a home agent, such as a router, generates a private key using public cryptographic parameters, that corresponds to the mobile host and the public key. The correspondent node uses the public key to encrypt a shared key and sends the shared key to the mobile host. The mobile host decrypts the shared key using the private key and uses the shared key to sign the binding update. Thereafter, the correspondent node utilizes the shared key to verify the authenticity of the binding update.
