一种简化的基于任务的信息网格访问控制模型

Simplified task-based access control model of the information grid

信息网格技术可以协调网络上的各种资源实现资源共享,它的安全机制主要包括数据安全和身份认证两个方面。本文将基于任务的访问控制机制应用于信息网格中,提出了一种简化的基于任务的信息网格访问控制模型。该模型不仅能满足信息网格的安全需求,还具有很多良好的安全特性,实现简单、易于操作,其实现思路对于设计信息网格中的访问控制机制提供了很好的参考价值。

Information grid technique can coordinate all kinds of resources on the network to implement the resources sharing. The security mechanism of the information grid includes data security and identity authentication. We propose a simplified task-based access control model of the information grid in this paper. This model of the information grid not only satisfies the security needs of information grid, but also has many other characteristics and can be implemented easily. Its implementation provides a good reference for the design of access control mechanism of the information grid as well.
