A method for authenticating address ownership using a Care-of Address (CoA) binding protocol, the method includes a comparison of two hash-function-processed result values, i.e., a first hash-function-processed result value transmitted from a home agent, the first hash-function-processed result value encrypted by a public key of a correspondent node and decrypted by a secret key of the correspondent node, and a second hash-function-processed result value piggybacked in a binding update message transmitted from a mobile node. The hash-function-processed result values are obtained by applying hash functions to a care-of address of a mobile node to be used in a foreign link, a random number generated by a home agent and a secret key shared by the home agent and the mobile node.
