Semantic Insecurity: Security and the Semantic Web

International audienceStrangely enough, the Semantic Web has fallen behind the rest of the Web in terms of security. In particular, we note how TLS is not in use currently for the majority of URIs on the Semantic Web, and how existing Semantic Web standards need to be updated to take into account security best practices. We point out security and privacy flaws in WebID+TLS, and propose alternatives and solutions

Distributed service environment (smart spaces) security model development

Access control mechanisms play a key role in many areas of computer science, however, for the information provided on the basis of semantic web and established solutions don't exist. This work focuses on the research in this area, in particular to ensure the information security in distributed service environments (smart spaces), which are the most promising application of standards and technologies of semantic web. The main focus of this paper will be devoted to the analysis and investigation solutions to develop security model and mechanisms for a smart space platform, as well as its comprehensive testing. As a test platform was chosen Smart-M3 platform, which has the highest degree of elaboration and maximum prospects for further applications

A commentary on standardization in the Semantic Web, Common Logic and MultiAgent Systems

Given the ubiquity of the Web, the Semantic Web (SW) offers MultiAgent Systems (MAS) a most wide-ranging platform by which they could intercommunicate. It can be argued however that MAS require levels of logic that the current Semantic Web has yet to provide. As ISO Common Logic (CL) ISO/IEC IS 24707:2007 provides a firstorder logic capability for MAS in an interoperable way, it seems natural to investigate how CL may itself integrate with the SW thus providing a more expressive means by which MAS can interoperate effectively across the SW. A commentary is accordingly presented on how this may be achieved. Whilst it notes that certain limitations remain to be addressed, the commentary proposes that standardising the SW with CL provides the vehicle by which MAS can achieve their potential.</p

Benefits and challenges of applying Semantic Web Services in the e-Government domain

Joining up services in e-Government usually implies governmental agencies acting in concert without a central control regime. This requires the sharing of scattered and heterogeneous data. Semantic Web Service (SWS) technology can help to integrate, mediate and reason between these datasets. However, since few real-world applications have been developed, it is still unclear which are the actual benefits and issues of adopting such a technology in the e-Government domain. In this paper, we contribute to raising awareness of the potential benefits in the e-Government community by analyzing motivations, requirements, and expected results, before proposing a reusable SWS-based framework. We demonstrate the application of this framework by a compelling use case: a GIS-based emergency planning system. We illustrate the obtained benefits and the key challenges which remain to be addressed
