摘要

XACML是用于分布式系统访问控制的国际标准。然而，XACML及其现有扩展不足以满足复杂的安全需求(例如，基于用户角色的访问控制、上下文感知授权和推理能力)。值得注意的是，XACML的广义扩展X-STROWL是一个全面的模型，它克服了这些缺点。在大量实现XACML的开源框架中，选择HERAS-AF作为最适合扩展实现X-STROWL模型的框架。本文主要对所提出的框架进行了体系结构设计，并与其他框架进行了比较。此外，还将介绍一个案例研究，以阐明该框架的工作流程。这是我们的研究对提供一个整体的、可扩展的和智能的授权决策引擎的重要贡献。

Towards a flexible framework to support a generalized extension of XACML for spatio-temporal RBAC model with reasoning ability

XACML is an international standard used for access control in distributed systems. However, XACML and its existing extensions are not sufficient to fulfil sophisticated security requirements (e.g. access control based on user’s roles, context-aware authorizations, and the ability of reasoning). Remarkably, X-STROWL, a generalized extension of XACML, is a comprehensive model that overcomes these shortcomings. Among a large amount of open sources implementing XACML, HERAS-AF is chosen as the most suitable framework to be extended to implement X-STROWL model. This paper mainly focuses on the architecture design of proposed framework and the comparison with other frameworks. In addition, a case study will be presented to clarify the work-flow of this framework. This is the crucial contribution of our research to provide a holistic, extensible and intelligent authorization decision engine.

期刊介绍： The Global Information Infrastructure is a daily reality. In spite of the many applications in all domains of our societies: e-business, e-commerce, e-learning, e-science, and e-government, for instance, and in spite of the tremendous advances by engineers and scientists, the seamless development of Web information systems and services remains a major challenge. The journal examines how current shared vision for the future is one of semantically-rich information and service oriented architecture for global information systems. This vision is at the convergence of progress in technologies such as XML, Web services, RDF, OWL, of multimedia, multimodal, and multilingual information retrieval, and of distributed, mobile and ubiquitous computing. Topicality While the International Journal of Web Information Systems covers a broad range of topics, the journal welcomes papers that provide a perspective on all aspects of Web information systems: Web semantics and Web dynamics, Web mining and searching, Web databases and Web data integration, Web-based commerce and e-business, Web collaboration and distributed computing, Internet computing and networks, performance of Web applications, and Web multimedia services and Web-based education.
