A secure communication system for improved software-defined networking

Abstract

The invention discloses a secure communication system for improving a software defined network. The secure communication system comprises an application layer, a secure communication service layer, acontrol layer and a forwarding layer, wherein the application layer comprises a plurality of clients, and the clients are used as request clients or target clients; and the security communication service layer is provided with a security database, and the security database stores a client identity identifier list, a security communication service layer public and private key pair, a plurality of client public keys and a plurality of client network addresses. The problem that privacy is prone to leakage due to the fact that information and data of an existing software-defined network are spreadon the network in a plaintext mode can be solved. The external malicious invasion is easily caused by programmability of a software-defined network, and the like.

Description

technical field [0001] The present application relates to the technical field of secure communication, in particular to a secure communication system for improving software-defined networks. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a reconstruction of the traditional network architecture, reconstructing the original distributed control network architecture into a centralized control network architecture. That is, on top of the distributed network connection, a centralized and unified control and management layer is introduced to realize global network management and dynamic response to upper-layer services. [0003] However, the entire network device resources of the existing software-defined network are exposed to the outside world, and there are hidden hidden dangers in resource access security. In particular, there are valuable information and data in network traffic, and these valuable information and data are used as The...

AI Technical Summary

Problems solved by technology

[0004] This application provides a secure communication system for improving software-defined networks, which can solve the problem that the information and data of the entire network of existing software-defined networks are transmitted in clear text on the network, resulting in easy leakage of privacy; and the programmability of software-defined networks leads to Vulnerable to external malicious intrusion and other issues
