Home network device, home network system and method for automating take ownership process

摘要

A network device for automating a TakeOwnership process includes a public key generation unit (110) for generating a public key and a private key by employing public key cryptography, a storage medium write/read unit (120) for writing the generated public and private keys on a storage medium and for reading the public and private keys written on the storage medium, and a control point/security console switching unit (150) for selecting one of a security console function providing an access authority for a predetermined device and a control point function controlling operation of the predetermined device, after authentication of a user using the private key stored on the storage medium. Thus, by employing public key cryptography in which a digital signature is created using the private key stored on the storage medium, such as a smart card, and is verified by the public key, the user can securely operate home network equipment as well as enjoy a convenience in use.
