Abstract

An external authentication method authenticates access a home network from outside the home network using temporal credential information. The method of authentication for the home network includes requesting a transmission of temporal credential information from the home server for authenticating a user, and receiving the temporal credential information from the home server. The temporal credential information is information including, for example, a temporal authentication key. Accordingly, the home user can access the home network by performing a facilitated and safer authentication using the temporal authentication key from outside the home network.

Claims

1. A method of authentication for home network, the method comprising:

storing and maintaining temporal credential information received from a home server;

transmitting, to a guest device, a hash algorithm and a guest authentication key which is generated based on the temporal credential information; and

transmitting, to the home server, at least one of a guest identification (ID) of the guest device, accessible service information, and a hash algorithm.

2. The method according to claim 1, wherein transmitting the guest authentication key and the hash algorithm is carried out through a location limited channel.

3. A method of authentication for a home network, the method comprising:

receiving a guest authentication key and a hash algorithm from a mobile device which transmits, to the home server, at least one of a guest identification (ID), accessible service information, and the hash algorithm;

transmitting guest authentication information to the home server; and

receiving, from the home server, at least one of user accessible service information and database state information.

4. A method of authentication for a home network, the method comprising:

storing and maintaining temporal credential information received from a home server;

transmitting, to a guest device, a guest authentication key for authenticating the guest device, and a hash algorithm; and

transmitting, to the home server, a guest identification (ID) of the guest device, an accessible service information, and the hash algorithm.
