| In recent years,with the rapid development of Internet, communication technology, multimedia technology and video surveillance technology has been widely used. Especially in the field of intelligent transportation, major cities have set up their own intelligent traffic video surveillance system to establish a safe, efficient, orderly and smooth travel environment. Video surveillance system bears monitoring and records the entire operation of urban road work all time, providing real-time traffic information for the regulation of the transport sector, but also providing the most direct evidence for law enforcement. The insufficiency of traditional authentication techniques in the tide of rapid development of Internet has become increasingly apparent, the security of video resources access become the focus of attention. In this context, it is great significance for the development of intelligent transportation that trusted module as the core of mutual authentication scheme is used in intelligent traffic video surveillance system, building to trusted access network-based video surveillance systems to manage and access to video information securely.This paper mainly includes the following aspects:(1) Research on System Framework. First architecture and topology of traditional video surveillance system is studied. It is founded that the traditional architecture cannot distinguish intranet and Internet users, only to verify the identity of the user but the terminal cannot be verified, which led to the safety to access server with public network cannot be guaranteed. This paper proposes a new mutual authentication scheme based on trusted module that is then applied to traditional architecture scene, produced a new video surveillance system architecture and topology. After comparing the analysis, the new system architecture can make up for the shortage of traditional architecture and have more security, better compatibility, easer to use.(2) Research on security bidirectional authentication architecture. As users’ password is easy to be cracked, one-way authentication technology is incomplete and the traditional authentication technology have the authentication distrust of the terminal,this paper presents an mutual authentication scheme, which corrects the above shortcomings effectively(3) Developing and testing a trusted module. In this paper, trusted module is the main development target and mutual authentication scheme will be implemented to the experiment and enable client and server to establish a connection by programming, which involves Linux, ARM and so many different hardware and software environments.Experiment verifies the feasibility of the scheme and accuracy of the conclusion with the command-line and interface way. |
