Business Of Grassroots Police Communication Software Based On .Net

Due to the particularity of the industry,security and confidentiality is an important requirement of the Police.Although there is lots pieces o f communication software such as QQ,Skype,however,because of the security work,they can not be used in the Police network.But,the Police internal organizational structure is too large and the business is too complex.At the same time the communication between different departments is very important for the Police,and the businesses can only be communicated internally.Through the exchanges of internal of the Police,can help the Police on dealing the business,and makes the process between different departments become more clearly.At the same time,it can help the Police find and correct the problems without delay.Therefore,it is necessary to use safe and effective immediate communication software in the Police's interior.This article is showing the functions of the safe immediate communication software: First,each police can apply for an account on the basic of the Police's ID.Second,each police can talk with others who are online in the internal network.Third,each user can transfer documents or files to others.And,this article realizes the safety aspect of the immediate communication software: Firstly,the communication between users has been encrypted with RSA algorithm.Each of the users has the only own key can decrypt the encrypted text.Secondly,the client database has been encrypted with RFC algorithm,and there is only the private key can decrypt the encrypted content.The client database has been encrypted connection,users can only connect their own database.In addition,in order to convenient to the Police to work,this software is aiming for the Police's job characteristics,and this software has been designed and implemented of the evidence collection and processing related functions.This software provides some simple operation for t he Police,and it improves the Police to handling cases more efficiency.Business of grassroots police communication software based on.Net that what technologies have been used in the software,such as: TCP model,CRC32 algorithm,dynamic link library,encrypt and decrypt by RSA algorithm,encrypt and decrypt by RFC algorithm,handle,form hidden side.Information exchange of TCP model is the main framework of this software.CRC32 check algorithm can ensure the correctness of the file transfer.RFC encryption and decryption,there is a fixed secret key for the user each time landing,generate a RSA key and user account password,sent to the server,the server decrypt with a fixed decryption key,after the user account verification.RSA encryption and decryp tion,this client software assigns a different private key to different users for every time when user logins on,besides of checking out the logging on user,the RSA algorithm will be used in exchanging information each time.Handle usage,different window controls have their own handle,through handle,you can accurately locate the form,add new messages on the window controls.Form hidden side,which achieves the form in the computer screen on the left,above,right can hide the form,that can help users not interfere with other operations.The Police internal network real-time communication software Based on.Net,except of achieving the Police users exchange information security and easy.And,this software integrated some functions those police daily used,this software is convenience to everyone to operate,keep secret for each police.
