The Research Of Security Access Platform In Digital Campus

With the development of information technology, as well as the popularity of networks, university campuses have also shifted from the traditional mode to the digital campus. It improves people's work efficiency and quality of life, but at the same time bring about many security risks as a result of the Internet's openness and anonymity. With the gradual deepening of Digital Campus, the increase in applications, types of increasing complexity of business, the rapid growth of user groups and active, digital campus security and management issues are becoming increasingly prominent. Therefore, an integration of all services on campus and have an independent security authentication, access authorization, transmission of information security features such as unified digital campus safety access platforms on the digital campus today has become a hot topic.This article is based on the campus network environments of the business application system of identity authentication, access authorization, single sign-and information security issues such as transmission, a system based on the work of PKI_PMI application layer in a unified platform for secure access Model, And focus on the system model of Access Authentication module, authorization management module has been designed and realized, And secure access platform for the safety analysis.First, the analysis of system design and realization of various elements related technologies. Focus on the PKI public key infrastructure, PMI authorized management infrastructure, PKI-based authentication technology, RBAC-based access control technology and application integration of Webservices. Analysis of the basic principles of their key technical features and advantages of practical application.Then, in order to Hunan Railway Vocational and Technical College as a case, the status quo for the campus network needs analysis and functional analysis. Given a unified platform for secure access to the system model, the composition of the structure, workflow design, etc.And then, Principle of the use of PKI technology to achieve the access authentication module, to resolve the current multi-application systems that exist in the user authentication and secure transmission problems; Application of the PMI based on the basic principles of RBAC authorization to provide centralized management capabilities, the realization of the user role-based access control to prevent unauthorized users access to authorized resources.Finally, secure access platform for the realization of the original system with seamless joints, the article on the security access of the resource integration platform has been designed modules;and Security and access platform to carry out a detailed security analysis. At the same time, Summed up the whole system design and implementation,proposed the future development trends and major research directions.
