Aaa Authentication Based On The Trusted Newspaper Network With Realization

With the development of the technology of computer networks and the growing application on computer networks, the scale of computer networks is getting bulky and complex, the categories of the devices are multiple, such as hosts, hubs, routers and switches, which are connected with networks, and the information flows on the networks are increasing rapidly. Therefore, security of the computer network become a very important issue.But, traditional security technology of network can not solve these problems efficiently. In order to overcome the existing deficiency of traditional security technology. This paper analyses some new theories of network security, such as trusted computing and trusted network.On the basis of characteristic analysis for trusted network, in order to strengthen security of enterprise networks . It is important that we strengthen control and audit to enterprise networks. Authentication Authorization Accounting protocol (AAA) can meet these requirements. This paper also introduces Remote Authentication Dial In User Service(RADIUS) protocol and data packet encryption in detail. Based on the above research , this paper puts forward Trusted Newsgroup Network Model based on AAA Protocol. By adding AAA protocol function in Local Area Network(LAN), strengthen control and audit in newsgroup networks. After adopting the method, we strengthen trusted degree of newsgroup core network. This paper analyses, designs and realizes the key part of the model. And the paper also introduce authentication procedure of user.According to Trusted Corporation Network Model based on AAA Protocol, after studying characteristic of Dazhong Newsgroup network,we design Dazhong Newsgroup network platform based on AAA protocol. Combination Application of Firewall and AAA Protocol in the News Network is put forward. With Challenge Handshake Authentication Protocol(CHAP) and digital signature, terminal machines access secret network of financing. Practice in Dazhong Newsgroup network proves that the method strengthens trusted degree of Newsgroup network.At present, the studies on trusted network platform are in the exploring phase.This paper proposes the viewpoints on the trusted network platform for medium-and-big size enterprises. We apply this model to network construction of...
