Research And Solution Of Information Security In Enterprise Instant Messaging System

Communication system is widely used in daily life and has become a necessary communication in daily life.In modern enterprises,employees often need to cooperate with other colleagues and cross-departmental cooperation in order to communicate with colleagues in different departments and complete more work in an all-round way under the limited resources.Employees use personal chat tools to communicate with non-company employees during the work period,which reduces the work efficiency;the personal communication software does not have high security requirements and does not do enough confidential work,so it can not effectively protect the enterprise data.Aiming at the problems raised above,in order to improve the working efficiency of the enterprise,the safety of the data information is guaranteed.This paper,based on the analysis of the encryption and decryption and the instant communication technology,has developed a set of instant communication systems for enterprises to solve the above problems.The subject research mainly includes the following parts:Firstly,the problems exposed in the use of personal communication software in enterprises are studied and analyzed,and the solutions to the problems are put forward.Secondly,the client side is developed by using Xilium.CefGlue embedded in WinForm,and the main functions are realized by loading HTML and JS files with custom browser controls.WEBSOCK,based on HTML5 realizes automatic connection and automatic reminder of new messages.Server side:using an open source SuperSocket engine.Finally,combining RSA algorithm and digital signature technology,based on the traditional RSA algorithm,the multi-key RSA algorithm is analyzed,and finally an instant messaging software based on RSA digital signature scheme is implemented.
