Abstract
A method and home network system for authentication between a remote terminal and a home network, which are connected with each other through a network, using a smart card are provided. The method includes enabling access between the remote terminal and the home network through the network, performing authentication using first shared secret data stored in a server smart card connected to the home network and second secret data stored in a client smart card connected to the remote terminal, creating a security tunnel between the remote terminal and the home network when the authentication succeeds.
Claims10
A method for authentication between a remote terminal and a home network, which are connected with each other through a network, using a smart card, the method comprising:
- (a) enabling access between the remote terminal and the home network through the network;
- (b) performing authentication using first shared secret data stored in a server smart card connected to the home network and second secret data stored in a client smart card connected to the remote terminal;
- and
- (c) when the authentication succeeds, creating a security tunnel between the remote terminal and the home network.
A method of issuing a client smart card that is connected to a remote terminal and used for authentication between the remote terminal and a home network, the method comprising:
- connecting the client smart card to be used for the remote terminal to the home network;
- receiving shared secret data to be shared with the client smart card from a server smart card connected to the home network;
- and
- storing the shared secret data received from the server smart card in the client smart card.
A home network system which performs authentication between a remote terminal and a home network using a smart card,
- wherein the home network comprises a home server that is connected with household appliances and a server smart card storing first shared secret data needed for authentication of the remote terminal;
- and
- the remote terminal comprises a terminal that is connected with a client smart card storing the first shared secret data and second shared secret data needed for the authentication and, when the authentication performed between the remote terminal and the home network using the first shared secret data and the second shared secret data succeeds, controls the home network to operate the household appliance.
