AAA server, home network access method and system

Abstract

The invention provides an AAA server and a home network access method and a system, relating to the field of network security, wherein the home network access method comprises the following steps of: sending a request of accessing a home network to an AAA server by a control terminal, wherein the access request comprises the account number of the home network; finding the IP address of the home gateway in the home network by the AAA server according to the account number of the home network; verifying the access right of the control terminal by the AAA server; after the access right of the control terminal passes the verification of the AAA server, generating a random number by the AAA server to serve as a session key of the communication of the control terminal and the home gateway; sending a security policy comprising the session key and the IP address of the home gateway to the control terminal by the AAA server; sending the security policy and the IP address of the control terminal to the home gateway; and carrying out communication between the control terminal and the home gateway by applying the security policy. The invention realizes the remote safe access of the home network by means of the security guarantee of network access.

Description

technical field [0001] The present invention relates to the field of network security, in particular to an AAA (Authentication Authorization Accounting, identity verification, authorization and statistics) server, a home network access method and system. Background technique [0002] With the development of the Internet and home appliance informatization, household broadband Internet access has become more and more popular. A family can have multiple information terminals, such as computers, digital TVs, videophones, video surveillance systems, etc. These information terminals can form a small home network, and can access the operator's network through the home gateway. The future home network may realize the interconnection and management of equipment including information equipment, communication equipment, entertainment equipment, household appliances, and even water, electricity, and heat meters, as well as data and multimedia information sharing. Through the network, ...

Problems solved by technology

However, this kind of solution has certain defects in the home network application. For example, the home network generally uses dial-up to access the network, and the gateway IP changes dynamically. It is necessary to search and set the IP address for each access.

The IP address of the control terminal remotely accessing the home network changes dynamically, and security policies such as IP address filtering cannot be applied

In addition, the security configuration of the home gateway is very professional, and most customers are not competent
