Abstract
An ownership sharing method and apparatus using a secret key in a home network remote controller are provided. A user who owns a home device generates an ownership authentication key using the secret key shared with the home device through the user's terminal device, and transmits the ownership authentication key to a terminal device of a particular user who wishes to share the ownership. The particular user can use the home device using the shared ownership authentication key, allowing for ownership of a device in home network environments based on a secret key that can be easily shared, obviating complicated calculation procedures that are no needed to share the ownership between an owner of a device and his family or customers, and achieving high security that is guaranteed based on the secret key.
