摘要:
 适当的访问控制机制是支持协作系统正常运行的一项关键技术。建立适当的授权策略在协作系统中是有困难的，往往将传统的授权机制模型应用在协作系统中，不能为多用户之间提供足够的支持。针对射孔校深数据协同处理平台，结合射孔数据协同处理的动态过程，提出一种支持协作的文件授权访问控制模型，使其更适合于协同工作环境的访问控制。重点分析了多用户之间的动态授权机制，采用文件信任评价机制保证权限文件的安全性，基于Hash-索引数据库，保证权限文件在协作系统中的唯一性。介绍了文件授权访问控制模型各组件的构成及具体应用。在该模型中，用户权限值会随着其他多个用户授权而动态变化，用户能够通过对权限文件进行信任评价来防止恶意分享文件，获取其权限。
Abstract:
 Appropriate access control mechanism is a key technology to support the normal operation of the collaborative work system. Construction of the appropriate authorization mechanism is very challenging for the cooperative system. The traditional access control sys-tem applied to the direct cooperation model is not enough for collaboration support among multiple users. In view of the dynamic process of the deep data processing platform and the collaborative process of perforating data,a file authorization access control model is proposed which supports collaboration,to make it more suitable for access control in collaborative work environment. It focuses on the analysis of the dynamic authorization mechanism between multi users in this paper,using the file trust evaluation mechanism to ensure the security of access files. Based on the Hash-index database,the uniqueness of the document in the collaborative system is ensured. The structure of file access control model and its application is introduced. In this model,the user rights value will change with other users’ behavior,and users can use the authority file to prevent malicious sharing files and access permissions.
