Secure multi-party network communication platform and construction method and communication method thereof

Abstract

The invention relates to a secure multi-party network communication platform and a construction method and a communication method thereof, and belongs to the fields of distributed systems and computer networks. The multi-party communication platform consists of a management node and a group of host nodes needing intercommunication; by Internet connection, the multi-party communication platform can realize secure and efficient multi-party communication and provide a secure channel for network application software deployed on the communication nodes; the security of the communication layer is realized by using a host identification protocol, and authentication security is realized by using a public key / secret key system on management; the protocol is realized by an open source and supports multiple common operating systems, so the cost of the scheme is very low; centralized member management adopted by the method is flexible and convenient; different from multi-hop forwarding and layer-upon-layer encryption of an onion router protocol, the data of a host marking protocol are finished in one hop between double communication parties and encrypted at one time, so the efficiency is greatly improved, and the data are totally transparent for upper application.

Description

technical field [0001] The invention relates to a safe multi-party network communication platform and its construction method and communication method, which can build a safe, easy-to-deploy and efficient network communication platform on the insecure Internet, and belongs to the field of distributed systems and computer networks. Background technique [0002] Internet applications have long become a necessity in people's lives, just like water and electricity. However, network communication is full of various unsafe factors: Hackers use Trojan horses to control botnets to carry out distributed denial of service attacks that can paralyze the target website; use hijacked domain name servers or ARP (Address Resolution Protocol) cache poisoning technology to conduct man-in-the-middle attacks, Make the attacked person disclose the user name, password, or be deceived by tampered information; simple sniffing attacks can obtain key information from poorly designed systems. Therefo...

AI Technical Summary

Problems solved by technology

In effect, onion routing is an ideal tool for establishing a secure multi-party communication platform, but in practice, onion routing is very inefficient and only provides connection-oriented services through proxies; in addition, a large number of user participation is required to achieve ideal security

All in all, onion routing is difficult to deploy and inefficient

[0005] To sum up, the existing technology cannot take into account cost, security, performance and manageability when building a multi-party communication platform
