Abstract
A home network system includes: a plurality of wireless devices cooperated with a home network, each device having a tag attached thereto to identify it; a tag reader for reading tag information from the tag of each wireless device; and a network manager for storing a shared key and identifying each wireless device connected to the home network using the tag information and supporting information exchange between the wireless devices by using the shared key.
Claims12
A home network system comprising:
- a plurality of wireless devices cooperated with a home network, each device having a tag attached thereto to identify it;
- a tag reader for reading tag information from the tag of each wireless device;
- and
- a network manager for storing a shared key and identifying each wireless device connected to the home network using the tag information and supporting information exchange between the wireless devices by using the shared key.
An apparatus for authenticating a wireless device by using a device's tag, comprising:
- a device database in which tag information read by a tag reader from a tag attached to a wireless device is registered;
- a key generator for generating an individual encryption key by encrypting a predetermined shared key by using the read tag information of the device;
- and
- a key transmitter for transmitting the generated individual encryption key to the device,
- wherein the wireless device decrypts the individual encryption key by using its tag information to obtain the shared key and exchanges information between other devices, which are provided in a home network together with the wireless device, by using the extracted shared key.
A method for authenticating each wireless device having a tag attached thereto in a home network system, comprising:
- registering tag information provided from a tag attached to a wireless device in a database;
- generating an individual encryption key by encrypting a predetermined shared key by using the tag information registered in the database;
- and
- transmitting the generated individual encryption key to the wireless device,
- wherein the wireless device decrypts the individual encryption key by using the tag information to extract the shared key and encrypts information exchanged between other devices, which are provided in a home network together with the wireless device, by using the extracted shared key.
