Abstract

The invention discloses a method of establishing a networking terminal safety domain and a system thereof. The method comprises the following steps that a first terminal node in a first safety domain and a second terminal node in a second safety domain carry out new domain configuration negotiation; after the new domain configuration negotiation is completed, the first terminal node and the second terminal node send a domain configuration updating instruction to other terminal nodes in the safety domains where the first terminal node and the second terminal node are located respectively; the other terminal nodes in the first safety domain and in the second safety domain complete configuration updating so that all the terminal nodes are joined in new safety domains. Through the method and the system in the invention, a networking node can complete domain configuration negotiation with a foreign domain through a non-encryption channel; through an encryption channel, domain configuration updating of a current domain is monitored and completed; when all the nodes in the two different domains are simultaneously divided into one new safety domain, operation of re-establishing the domain is simple and flexible; and signaling interaction expenditures of the terminal nodes can be reduced and an error rate is decreased so that a process of establishing the safety domain is high-efficient, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of broadband communication, in particular to a method and system for establishing a security domain of a networked terminal. Background technique [0002] With the development of information technology, the bandwidth of home broadband is getting higher and higher. The wiring of many broadband users' homes is insufficient, which has become a bottleneck in the deployment of telecom services. In order to improve the coverage of telecommunication services in users' homes, the home networking technology based on new home networking terminals will be widely used. A security domain refers to a subnet or network within the same system that has the same security protection requirements, trusts each other, and has the same security access control and boundary control policies. The division of security domains is the basis for ensuring the stability and normality of the network and infrastructure, as well as the basi...
