Method, system and equipment for data interaction

Abstract

The invention discloses a method of data interaction, which is applied to a system comprising an LNS, an LAC and client equipment. The method comprises the following steps: the LNS receives the user name, the password and the unique identification of the client equipment of the LAC; the LNS judges the legality of the client equipment according to the user name, the password and the unique identification of the client equipment. If the client equipment is judged to be legal, business data interaction is conducted with the client equipment by the LAC, and if the client equipment is judged to beillegal, the business data interaction with the client equipment is rejected. In the invention, the LNS certificates the client equipment according to the user name, the password and the unique identification of the client equipment, thus preventing a malicious user from acquiring a legal user name and a legal password from using any client equipment to access the inner network of an enterprise and effectively protecting the safety of inner data and network of the enterprise.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data interaction method, system and equipment. Background technique [0002] VPDN (Virtual Private Dial-up Network, virtual private dial-up network) is a client device that accesses through a wired communication network such as ISDN (Integrated Service Digital Network) or PSTN (Public Switched Telephone Network, public switched telephone network) In the public network, the virtual private network is formed by using the virtual private tunnel in the public network to connect with the server equipment inside the enterprise. VPDN technology uses a dedicated network communication protocol, which can establish a virtual private network with high security and reliability on the public network. Remote users (for example, overseas offices of enterprises) can realize the network connection with the enterprise headquarters through the virtual private network establi...

Problems solved by technology

Although this processing method guarantees the security of the internal data of the enterprise to a certain extent, if the user name and password of the client device are leaked, or other users obtain the legal user name and password through illegal means, any client device can be used. The device is connected to the LNS, stealing data in the private network of the enterprise or destroying the private network of the enterprise

Therefore, the existing LNS authentication mechanism for client devices has security risks and cannot effectively protect enterprise data and network security
