Enterprise Instant Messaging System Deployment Scheme And Inter-system Cross-Domain Authentication

Instant messaging is an application that can send and receive Internet messages instantly.It plays an increasingly important role in life and work.However,the current mainstream instant messaging service is provided by a third party,and the server is deployed in the service provider's computer room.Data security issues are frequently reported.In the context of the rapid development of big data mining technology and the increasing ability of data analysis,protecting data security is becoming more and more important for enterprises.It is critical for enterprise users to deploy an independent and secure instant messaging system.This paper combines the current technology trends,weighs the technical and economic costs,and designs the instant messaging system deployment plan.To solve the mutual authentication between systems,a cross-domain authentication scheme based on blockchain technology is proposed.First of all,it expounds the current status and development trend of mainstream instant messaging tools at home and abroad.The origin and development status of cloud computing technology and blockchain technology are introduced.It also introduces the development status of cross-domain authentication under cloud computing.Cloud computing and blockchain will serve as the technical foundation for deploying instant messaging systems.Then,based on the usage scenarios of enterprise users and the technical trends of cloud applications,the security issues of enterprise-level instant messaging tools,especially the use of third-party software,users cannot fully grasp the security of chat data and the data are easily analyzed by others.Leaking corporate secrets.Compare the advantages and disadvantages of local deployment and cloud deployment,and analyze the security risks of SaaS deployment.A set of instant communication system based on SaaS is proposed.The system is deployed in C/S mode,deploying the server in the cloud,and using end-to-end encryption technology for encrypted communication.The solution enables users to deploy independently,enabling private control of the server and encrypting stored data information.Security analysis was performed on common attack methods,and the necessary functions of the system were tested to verify the security and reliability of the system.Finally,due to the private property of the system,the instant communication between enterprise partners is inconvenient.To solve this demand,the PKI cross-domain authentication model is analyzed,and the blockchain technology can not be modified,distributed storage,and node maintenance.Based on the characteristics,a cross-domain authentication model based on federated chain is proposed,and the protocol flow of cross-domain authentication is given.The solution effectively solves the problems of long authentication path and complicated structure in the traditional cross-domain authentication process,and has the characteristics of not changing the original system authentication structure and good scalability.And a security analysis of the system.
