Abstract:
A method and an apparatus for authenticating device in a multi-domain home network environment are provided to disperse a root CA(Certification Authority) to home gateways and guarantee extension by providing an authentication through the agreement between local domains. An apparatus for authenticating device in a multi-domain home network environment includes a cross domain authentication unit(631), a device registration unit(632), and a device certification unit(633). The cross domain authentication unit exchanges a cross domain certificate for certifying a public key and agreement by performing the agreement of coupling inter-local domains through a different local domain and a public key-based structure to authenticate a device registered in a different local domain. The device registration unit issues the local domain certificate used in the local domain by certifying the device for requesting the registration. The device certification unit receives the local domain certification from a service request device, and certifies the received local domain certificate with an own public key or the public key acquired from the cross domain authentication unit. The device certification unit generates and provides a session key to be shared with the service request device to the device if the local domain certificate is available.
Abstract:
A method for authenticating a user with an ID and a password is provided to authenticate a server and authenticate a client user after the server is authenticated in a home network environment by using a certificate of the server, and enable a client to authenticate the user by using the ID/password without using the certificate while using the certificate of the user for user authentication between the client and the server. The client transmits a message including information indicating the user authentication uses the ID/password to the server. The client receives and verifies the certificate of the server. If the received certificate is verified, a password key used in the server is generated and shared through key generation/exchange. The client authenticates the user by calculating a hash value for copied user authentication data corresponding to original user authentication data and encoding the hash value with the password key.
Abstract:
An access pointer for interworking a PLC(Power Line Communication) network with a wireless network and a method therefor are provided to service the wireless network easily interworking in plug-in way to a home network constructed by power lines, thereby eliminating cost factors while easily utilizing new wireless network equipment in the home network. A PLC module(320) transceives data through MAC(Media Access Control) of a data link layer from a PLC network. A wireless communication module(340) transceives data through the MAC of the data link layer from a wireless network. A conversion gateway(330) converts layer data which is more than a network layer of the data received through the PLC module(320) into a certain type proper for a wireless network layer to output the converted data to the wireless communication module(340), or converts layer data which is more than a network layer of the data received through the wireless communication module(340) into a certain type proper for a PLC network layer to output the converted data to the PLC module(320).
