Application Of Ssl Vpn In Jigang Remote Access Operation

Today, popularization of internet and information system extend the border of communication, ERP and OA help enterprise to strengthen their management, Network makes remote access easily.SSL VPN can make a road between remote users and company headquarters by using encrypt communication protocol, it seems as a special line. Different from IPSec VPN, it can use and maintenance easily and does not need change network structure in existence; It is mobile and user needn't install any client programl; It has strong ability of access control and can make remote users accessing B/S and C/S applications and resource from company headquarters.This paper combines remote operation access of Jinan Iron & Steel Group and use SSL technique to build VPN, it can make remote users accessing B/S and C/S applications as OA, ERP, measure and quality from company securitily. Study comprehensively technology of VPN--Include the background, classify, application field, correlation technology, crypto protocol, etc, then analyse and compare them, in order to choose or use perfect network and protocol type to meet practice.Analyze SSL secure protocol PKI technology. Understand the principle working process of SSL protocol, comprehend the important application in identity authentication, secure data transmission, no renounce, and data integrality. understand how SSL cooperate with all parts how SSL protect data, this leads SSL VPN project possible and foundate base theory of SSL VPN gateway for Jinan Iron & Steel Group.Combine remote operation access of Jinan Iron & Steel Group and use SSL technique to build VPN, it can make remote users accessing B/S and C/S applications as OA, ERP, measure and quality from company security. It support many kinds of mode of identity authentication, and can accredit and auditTest the function and capability of SSL VPN gateway we realized, analyze the result, the result will enhance and reference secure VPN gateway's function and capability later.
