多电视台临时协作的安全模型

A Security Organization Model for Temporary Collaboration among Multi-TV Stations

多电视台经常需要为完成共同任务并取得各自利益而临时地组织成一种协作的联盟。多电视台的协作增强了组织的复杂性,协作中各自媒体内容的安全性也尤为重要。本文将进程代数中的封箱演算引入到多电视台临时协作组织模型的方法描述中,给出了多电视台临时协作组织模型建模方法和建模工具原型,以形式化的方式体现了多电视台临时协作组织结构的动态性,资源权限的易变性,和对各自资源的安全控制。

Many TV stations often need to temporarily organize into an alliance of collaboration for common tasks and their own interests. The collaboration among multi - TV stations enhances of the complexity of the organization. The security of media contents in the alliance is of particular importance. In this paper, a new kind of the organization structure describing method based on Seal - Calculus of process algebra for temporary collaboration among multi-TV stations is presented, which is convenient to express the dynamic process of the system and the changeability of access authorization for resource, which provides a new formalized means to describe the security control of TV stations own resources. Upon this method, a modeling prototype system is given.
