Communication method, and security policy negotiation method and system for supporting trusted network connect

Abstract

The invention discloses a communication method, a security policy negotiation method and system for supporting trusted network connect. The communication method is used for the communication between a trusted network connect (TNC) network and a local network for a non-trusted network connect network. The communication method comprises the following steps: the local network supports a cross-domain interface for federated trusted network connect (IF-FTNC) interface; when the TNC network requests to access a communication entity of the local network, the local network performs policy negotiation with the TNC network through the IF-FTNC interface; and if a negotiation result of the policy negotiation allows communication, the TNC network directly communicates with the local network. According to the communication method disclosed by the invention, the problems of heterogeneous cross-domain security policy negotiation and communication are solved, and the policy interaction and communication of the non-trusted network and the TNC network are realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, a security policy negotiation method and system supporting trusted network access. Background technique [0002] Convergence is the trend of network development, and a solution based on security policies is an inevitable choice for future network security management. With the development of network convergence, business diversity and equipment complexity make the security of the entire network more and more complicated. Therefore, complex manual configuration can no longer meet the needs of network development, and solutions based on security policies can provide network security management methods that optimize efficiency, unify security, and facilitate operation. [0003] The purpose of the unified security policy framework is to implement unified management of security devices on the entire network based on policies, and realize the colla...

AI Technical Summary

Problems solved by technology

[0006] At present, the policy interaction and communication scheme between the unified security policy framework and the existing TNC network has not been proposed in the existing technology, and it is impossible to realize heterogeneous cross-domain security policy interaction and end-to-end secure communication
