Research And Implementation On IPv6 Access Authentication System Based On SAVI

With the soaring development of Internet,Internet become the significant platform for human obtaining information,studying and communicating and leisure and entertainment.Facing to continuously extending Internet scale and netizens number,IPv4 design's thought limitation and places short emerge endlessly.The attack issues with counterfeit address on the Internet pose huge dangerous for Internet security management.In order to thoroughly solve IPv4 problems,the next generation IPv6 technologies rise in response to the proper time and conditions.On the other hand,with the mobile Internet era coming,the complexity of users connected in WLAN and Internet openness bring the new challenges for Internet security management.Access authentication technologies could realize users' identity authentication and is one of the important technologies to realize the effective management for Internet security.Convenient and reliable certification system are quite important for users and Internet managers.Following IPv6 technologies' continue distribution and application in WLAN,how to ensure IPv6 users safely access into Internet and to improve Internet manageability is the new problems for wireless access network.This thesis makes analysis about the current source address verification techniques and selects SAVI technology under SAVA source address verification framework to realize access network's source address.Simultaneously,it analyzes IPv6 technologies features and state quo.After making full investigation and analyzing current mainstream AN authentication technology,in line with SAVI source address verification methods and Web verification methods' technological features,the author designs and realizes the design about safely accessing authentication system for mobile end-users under IPv6 Internet environment.The innovation point of this paper is to realize mobile terminal security access verification under double stacks Internet environment as well as provide a quick and effective finger certification function for the mobile users who possess finger identification function to support finer grit based on users' security access verification.The stress of the thesis is through accessing switch's flushbonading Linux development platform to achieve access users security management control.It designs and realizes the correspondent functional model,including SAVI module,communication module,HTTP redirection module.Aiming to the main module design,it makes the statement and delivers the basic principles for authentication server-side to realize access control.Finally,it presses ahead the functional examination for the whole system and analyzes the results.By virtue of the results,it tests that the correct of the system design and plan's feasibility.
