面向云计算环境的多源信息服务模式设计

A Cloud Computing Oriented Design of Multisource Information Service Models

从基本结构、服务过程、服务特点和应用实例等方面详细分析了3种典型环境下的多源信息服务模式,以及云计算环境下的2种多源信息服务模式。在此基础上,从安全性的角度提出了一种基于可信第三方监管的云计算环境下多源信息服务模式,并从角色设计、服务过程、监管策略以及监管成本等方面进行分析和设计,能够为信息服务提供安全性保障。

This paper makes an analysis and a comparison of three multi-source information service models in typical environment and other two models in cloud computing in details from the basic struc- ture, service process, service characteristics and their applications. On the basis of it, according to the characteristics of muhi-source information service in cloud computing, a multi-source information service model based on trusted third-party supervision in cloud computing is proposed from a security view. And it is analyzed and designed from character design, service process, supervision strategy and supervision cost. This model can provide information service with security protection.
