摘要
针对校园一卡通信息系统中集成的关键问题及信息访问的安全问题,基于元数据层面的集成技术,建立各种主题元模型,解决大学校园不同部门数据异构的集成问题,并提出"四层安全"结构模型,采用DES加密算法实现数据的加密.应用结果表明,校园一卡通"四层安全"结构模型及关键技术的应用,实现了对校园各种信息系统的集成与共享,安全有效,应用效果良好.
Specifically for the safety that integrated the key question and information visit in campus one cartoon information system, owing to the integrated technology of data face tier, the various subject of building up is basic model, the campus resolving university is unlike integrated branch data isomerism problem, bring forward 'four layers of safe' structural model, adopt the DES encrypt algorithm to realize the data encrypt. Result indicates application, campus one cartoon 'four layers of safe' structural model and key technology apply, the integration having come true to various information system of campus is effective with the share, safety, the effect of applying is fine.
