Abstract
A method and apparatus for encrypting a home address of a mobile node, in which the mobile node implements a host-based mobility protocol during wireless communications with a home agent. The method includes applying an encryption algorithm on the home address to generate an encrypted home address, and placing the encrypted home address within a destination option of a payload packet. The payload packet is sent by the mobile node while away from a home network associated with the mobile node.
