A Trusted Access Authentication System Based on Virtualized Network

Abstract

A trusted access authentication system based on a virtualized network, comprising: a virtual trusted access switching component, the virtual trusted access authentication component includes a trusted Open vSwitch and a trusted access switching controller, configured for Provide virtual network support for network access authentication of virtual machines in the virtual network according to the virtual verification result; a trusted access authentication component, where the trusted access authentication component includes a trusted access authentication client located in the virtual machine in the virtual network terminal and a trusted access authentication server located at the control node; a trusted access management component, the trusted access management component includes an isolation repair server located in a virtual machine in a virtual network and a trusted access terminal located at the control node At the authentication management end, the trusted Open vSwitch includes preset flow table rules with virtual machine network authorization information, and the trusted Open vSwitch provides virtual network support to the virtual machine based on the preset flow table rules. The invention can realize effective control of virtual machine network access.

Description

technical field [0001] The invention relates to a virtualized network, an SDN software-defined network, a TNC trusted network connection and remote certification, in particular to a trusted access authentication system based on a virtualized network. Background technique [0002] The application of cloud computing in social life and daily office environment brings many conveniences, but also brings corresponding security risks and challenges. From a technical point of view, cloud computing realizes the pooling of computing resources, storage resources and network resources in the data center through virtualization technology, which can be allocated and used by users in the cloud center, which brings a lot of convenience to users. The introduction of virtualized resources also brings new risks such as difficult management of virtualized resources and difficult to define the boundaries of virtualized networks. Malicious attackers invade the virtualized network by attacking vir...

From a technical point of view, cloud computing realizes the pooling of computing resources, storage resources and network resources in the data center through virtualization technology, which can be allocated and used by cloud center users uniformly, which brings a lot of convenience to users. However, virtualization technology The introduction of virtualization also brings new risks such as difficult management of virtualized resources and difficult definition of virtualized network boundaries. Malicious attackers invade virtualized networks by attacking virtual machines, spread viruses or steal information and data in virtualized networks, causing The business applications and user data running on the cloud computing platform bring serious security threats, and the access threats of the virtualized network are difficult to be protected by traditional network security equipment
