The Research And Implementation Of Security Mechanisms In Mobile IM System

In this age of information,instant messaging has become a necessity and everywhere.Instant messaging is like a link,closely connected to an individual,a group of people,so that people enjoy the great convenience of technology brought about by the great progress.Today's popular instant messaging software such as WeChat,Skype,and WhatsApp all have self-developed communication protocols and program code.With the cooperation of professional technical teams,it has undergone many iterations over many years and has high security.However,it is undeniable that due to the commercial background of commercial companies,the implementation details of these popular instant messaging systems are destined to be the core secrets of major companies.Other open source instant messaging systems are instant messaging systems based on open source protocols,which are usually implemented and maintained by the open source community.The open source community is subject to the complex logic implementation and high cost of learning of the instant messaging system.The instant communication function of the communication system does not provide the security guarantee of the related system.This article is based on the above scenario considerations and has done some security research work on the Android client and server side of the current weak security of open source instant messaging systems.An Android shell verification mechanism and an authentication mechanism based on RSA algorithm are proposed.The two security mechanisms are designed and implemented.Finally,based on these two security mechanisms,the instant messaging system is implemented and tested and verified.The security mechanism of the instant messaging system developed in this paper can effectively protect the instant messaging system from external security threats from multiple aspects of the client,server,and transmission process.At the same time,the instant messaging system with security mechanism can be well implemented.Instant messaging functionality.The research and implementation of the instant messaging security mechanism in this article will be of great significance for internal research in universities,internal development,and the development of instant messaging security industry.
