Enabling cross-organizational cooperation in ubiquitous computing environments poses new security challenges that concern particularly the interoperability of security management systems and the security policies of each organization. In this paper, we present a semantic framework for cooperative security management processes design in a cross-organizational context. Our framework is based on a hybrid...
The complexity of developing and deploying context-aware pervasive-computing applications calls for distributed software infrastructures that unobtrusively support to contextual data collecting, information sharing and security privacy controlling. In this paper, we motivate a human-centric design for such an infrastructure to support context-aware applications. A novel peer to peer based semantic...
Pervasive Environments offer new opportunities for users to dynamically access resources and services based on information characterizing their situation (context), generally assuming that this information is correct and trustworthy. In this scenario, the Quality of Context information (QoC) plays an important role for improving context-based adaptation processes and for ensuring the correct behavior...
Ubiquitous computing environment pursues context-aware in order words personalized service by collecting contexts through sensors located over wide area and presenting the service automatically depending not on the user's request but on the situations that are needed. But in order to provide the personalized service, contexts collected through various sensors are needed and they include private information...
In order to solve the contradiction between information sharing and security privacy in the ubiquitous computing environment, a novel context policy management framework based on ontology is presented. The semantic specification of policy and dynamic policy implementation are described. And the usefulness and flexibility of our proposed framework are demonstrated by a typical ubiquitous computing...
The increasing number of devices that are invisibly embedded into our surrounding environment as well as the proliferation of wireless communication and sensing technologies are the basis for visions like ambient intelligence, ubiquitous and pervasive computing. PErvasive Computing in Embedded Systems (PECES) project is committed to developing the technological basis to enable the global cooperation...
With the ongoing trend towards the globalization of software systems and their development, components in these systems might not only work together, but may end up evolving independently from each other. Modern IDEs have started to incorporate support for these highly distributed environments, by adding new collaborative features. As a result, assessing and controlling system quality (e.g. security...
With rapid development of computer networks, users need a new solution for network security management, aiming at integration. This paper focuses on context-aware alert analysis, which is one of its key functionalities. A practical and efficient approach to guarantee unified representation of context information, background knowledge and attack knowledge for security alerts is still lacking these...
