面向Web服务工作流系统的访问控制模型 总被引:1,自引:0,他引:1
提出了一种面向Web服务工作流系统的访问控制模型(WSWF-RBAC)。在基于角色的访问控制模型基础上引入系统资源的概念,把Web服务对象、属性和其它功能模块当做资源统一管理。引XT资源访问模式的概念,在约束条件下通过与资源的运算生成系统权限,从而实现了对权限的精细管理和动态调整能力。通过扩展web服务访问的角色集和用户集,并引入角色扮演对象,实现了工作流系统中Web服务与其它模块访问控制的一致性。将该模型应用于库房供应链系统中,运行结果表明,该模型能够增强Web服务工作流系统授权的灵活性和安全性。 相似文献

云计算是一种能够向各种互联网应用提供硬件服务、基础架构服务、平台服务、软件服务、存储服务的系统,而SOA是一个组件模型,它将依靠各服务之间定义良好的接口和契约的应用程序联系起来。云计算与SOA紧密地结合,形成一种基于SOA的云计算框架模型。而中间件技术则是云端建设最重要的技术,构建基于SOA架构的云中间件则是充分实现了云计算与面向服务架构的优势组合,对构建企业私有云建设与相关应用将起到决定性进作用。 相似文献

面向服务的体系结构由于其结构的松散性和计算的动态性等特点,使得其安全管理更加复杂。提出了一个面向服务的角色访问控制模型,该模型通过引入环境角色等概念来描述动态的上下文约束条件,并在授权时使用增强权限约束机制,提供了一种更为灵活的授权方法。此外模型通过增强的权限集,将分派给角色的任务与需求权限之间关联,有效地加强系统的安全性和访问控制的灵活性,也更适用于具有复杂安全特性的面向服务的软件环境。 相似文献

We introduce a middleware infrastructure that provides software services for developing and deploying high-performance parallel programming models and distributed applications on clusters and networked heterogeneous systems. This middleware infrastructure utilizes distributed agents residing on the participating machines and communicating with one another to perform the required functions. An intensive study of the parallel programming models in Java has helped identify the common requirements for a runtime support environment, which we used to define the middleware functionality. A Java-based prototype, based on this architecture, has been developed along with a Java object-passing interface (JOPI) class library. Since this system is written completely in Java, it is portable and allows executing programs in parallel across multiple heterogeneous platforms. With the middleware infrastructure, users need not deal with the mechanisms of deploying and loading user classes on the heterogeneous system. Moreover, details of scheduling, controlling, monitoring, and executing user jobs are hidden, while the management of system resources is made transparent to the user. Such uniform services are essential for facilitating the development and deployment of scalable high-performance Java applications on clusters and heterogeneous systems. An initial deployment of a parallel Java programming model over a heterogeneous, distributed system shows good performance results. In addition, a framework for the agents' startup mechanism and organization is introduced to provide scalable deployment and communication among the agents. 相似文献

Service-Oriented Architecture (SOA) is widely adopted for building mission-critical systems, ranging from on-line stores to
complex airline management systems. How to build reliable SOA systems becomes a big challenge due to the compositional nature
of Web services. This paper proposes an adaptive QoS-aware fault tolerance strategy for Web services. Based on a user-collaborated
QoS-aware middleware, SOA systems can dynamically adjust their optimal fault tolerance configurations to achieve optimal service
reliability as well as good overall performance. Both the subjective user requirements and the objective system performance
of the Web services are considered in our adaptive fault tolerance strategy. Experiments are conducted to illustrate the advantages
of the proposed adaptive fault tolerance strategy. Performance and effectiveness comparisons of the proposed adaptive fault
tolerance strategy and various traditional fault tolerance strategies are also provided. 相似文献

Service-oriented architecture (SOA) has emerged as a dominant architecture for interoperability between applications, by using a weakly coupled model based on the flexibility provided by web services, which has led to a wide range of applications, which is known as cloud computing. On the other hand, multi-agent system (MAS) is widely used in the industry, because it provides an appropriate solution to complex problems, in a proactive and intelligent way. Specifically, intelligent environments (smart city, smart classroom, cyber-physical system, and smart factory) obtain great benefits by using both architectures, because MAS endows intelligence to the environment, while SOA enables users to interact with cloud services, which improve the capabilities of the devices deployed in the environment. Additionally, the fog computing paradigm extends the cloud computing paradigm to be closer to the things that produce and act on the intelligent environment, allowing to deal with issues like mobility, real time, low latency, geo-localization, among other aspects. In this sense, in this article we present a middleware, which not only is capable of allowing MAS and SOA to communicate in a bidirectional and transparent way, but also it uses the fog computing paradigm autonomously, according to the context and to the system load factor. Additionally, we analyze the performance of the incorporation of the fog computing paradigm in our middleware and compare it with other works. 相似文献
