Network security communication system based on block chain smart contract

Abstract

The invention discloses a network security communication system based on a block chain smart contract, and belongs to the technical field of digital information transmission. The system comprises a network isolation module, a user-defined configuration module, an authorized access module, an intelligent contract module, a certificate management module, an automatic deployment module and a sentry verification module. Network isolation is carried out through a network isolation module by adopting an ebpf network firewall and utilizing a micro-segmentation technology; through the custom configuration module, a system administrator configures custom resources and authorization rules on the platform and initiates voting; the administrator votes and manages the management event through the trusteeship and security contract on the block chain by using the authorization access module; querying a contract through an intelligent contract module to obtain a corresponding state change; generating a CA certificate by using a certificate management module; automatically deploying a client and a service team sentinel by using an automatic deployment module according to CA certificate information injection; and the guard verification module is used for accessing a specified interface.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a network security communication system based on blockchain smart contracts. Background technique [0002] The traditional security model is gradually improved based on the boundary model. The traditional boundary-based network security architecture uses firewalls, WAF, IPS and other boundary security products / solutions to protect the enterprise network boundary. The perimeter model focuses on defending the perimeter, keeping attackers out as much as possible, leaving nothing inside. In the existing service architecture, the boundary-based network access security model is gradually ineffective, and there are shortcomings such as inability to flexibly control access rights. [0003] With the development of business and the increase of traffic, resisting external / internal risks, increasing availability, and achieving a balance between security and availabi...
