Abstract

The embodiment of the invention discloses an SDN edge computing network system based on blockchain encryption, an encryption method and a medium. The embodiment of the invention provides a technical scheme. Encrypting the configured and updated network strategy through the application layer and sending the encrypted and updated network strategy to the blockchain layer; the block chain layer receives the network strategy and decrypts the network strategy; and performing consensus authentication on the decrypted network strategy through a plurality of consensus nodes, storing the authenticated network strategy in the blockchain network in a distributed manner, extracting the network strategy from the blockchain layer by the control layer, and issuing the network strategy to the data forwarding layer, so that the data forwarding layer performs data forwarding according to the network strategy. By adopting the technical means, the security of network strategy transmission and issuing can be guaranteed, and data loss and network internal attacks are avoided. And furthermore, by storing administrator account address information, the identity of a network strategy configurator is convenient to determine, so that a basis is provided for tracing the identity of an attacker in the network.

Description

technical field [0001] The embodiment of the present application relates to the technical field of network systems, and in particular to an SDN edge computing network system, encryption method and medium based on blockchain encryption. Background technique [0002] SDN network (Software Defined Network, software-defined network) is an implementation of network virtualization. By separating the control plane of network equipment from the data plane, it realizes flexible control of network traffic, makes the network more intelligent as a pipeline, and provides a good platform for core network and application innovation. The typical architecture of an SDN network is generally divided into three layers, from top to bottom are the application layer, control layer and data forwarding layer. The application layer and the control layer are connected through the northbound interface, and the control layer and the data forwarding layer are connected through the southbound interface. ...
