For an e-government system security instant messaging program , the first of instant communication technology status and development trend of a brief introduction , followed by the use of the e-government platform instant messaging technology to analyze the actual situation , combined with network security and modern cryptography proposed a secure instant messaging platform solutions . Secure instant messaging system includes a central server systems , messaging server system , the client system, three systems . This article focuses on the central server system and the client system design and implementation. Used between the client and server hybrid P2P model, based on the XMPP protocol implementation includes instant messaging , based on DirectShow streaming media framework , based on UDP protocol file transfer , including instant messaging system basic functions. Based on PKI technology transfer files between the client and streaming media transmission of authentication, integrity, confidentiality and non-repudiation . Meanwhile, in order to upgrade the software to facilitate subsequent maintenance of the system to achieve the automatic software upgrade module ; in order to prevent illegal copying of software , design and implement software product authorization module .
