National Science FoundationDistributed Systems Research CISE/CNSABSTRACTPROPOSAL NUMBER: 0411961PRINCIPAL INVESTIGATOR: Tripathi, AnandINSTITUTION: University of Minnesota-Twin CitiesPROPOSAL TITLE: Secure Context-Aware Distributed Collaboration SystemsAn important need in today's computing environments is to support ubiquitous collabora-tive activities involving mobile users working across different autonomous organiza-tions. In such activities, the security policies for resource access and user interactions are generally required to be context-based. A user context may be based on various aspects such as physical location, network domain, roles in activities, user interface devices, and any temporal constraints. A mobile user needs to be given access to local and remote re-sources based on the current context. Moreover, it is desired that resource discovery and binding functions are executed transparently and proactively by the application environ-ment and the underlying infrastructure services. Such ubiquitous collaboration environ-ments need decentralized mechanisms for managing and enforcing policies for resource discovery, binding, and protection. The primary focus of this project is on developing system level mechanisms for constructing secure context-aware ubiquitous collaboration environments from their high level specifications. The specification model will support expression of context-based dynamic security policies for users, applications, as well as service/resource providers. This project will result in a middleware framework to realize from specifications a desired environment with context-based policies. This framework will include mechanisms for proactive discovery and transparent binding of resources for an application. It will support construction of context-aware smart environments by mod-eling infrastructure services as autonomous agents interacting with mobile users. Mecha-nisms based on distributed trust and delegation will be included for decentralized policy enforcement. The infrastructure resulting from this work will be made available for re-search and education.Dr. Brett D. FleischProgram Director, CISE/CNSMay 26, 2004..

国家科学基金会分布式系统研究CISE/CNSABSTRACTPROPOSAL编号：0411961主要开发者：Tripathi，Anand机构：明尼苏达大学双城分校PROPOSAL标题：安全上下文感知分布式协作系统在当今的计算环境中，一个重要的需求是支持无处不在的协作活动，包括跨不同自治组织工作的移动的用户。在这些活动中，资源访问和用户交互的安全策略通常需要基于上下文。 用户上下文可以基于各种方面，诸如物理位置、网络域、活动中的角色、用户接口设备和任何时间约束。一个移动的用户需要被给予访问本地和远程资源的基础上的当前上下文。此外，希望资源发现和绑定功能由应用程序和底层基础设施服务透明地和主动地执行。这种无处不在的协作工具需要分散的机制来管理和实施资源发现、绑定和保护策略。这个项目的主要重点是开发系统级的机制，用于构建安全的上下文感知无处不在的协作环境，从他们的高层次规范。该规范模型将支持用户、应用程序以及服务/资源提供者基于上下文的动态安全策略的表达。这个项目将导致一个中间件框架，实现从规范所需的环境与基于上下文的政策。该框架将包括主动发现和透明绑定应用程序资源的机制。它将通过将基础设施服务建模为与移动的用户交互的自主代理来支持上下文感知智能环境的构建。 基于分布式信任和授权的机制将被包括在分散的策略执行中。 这项工作所产生的基础设施将用于研究和教育。Fleisch Program Director，CISE/CNS May 26，2004..
