Personalised, Context-aware Composition of Pervasive Mobile Services

This paper discusses some of the challenges encountered when using policy-based management to manage pervasive m-Government services. Users within a pervasive computing environment can take advantage of pervasive m-Government services if management of these services is developed and integrated into the environment's management system. The mobility of the user is a key feature of pervasive computing environments. Adapting the management system to account for user's mobility is a challenging and highly active research area. Application of policy based management techniques appears to have the potential to successfully manage the provision of services across multiple management domains, however this potential will only be realised if solutions to a number of challenging research issues are realised. In particular, current policy based management techniques do not fully support user or service mobility across management domains. Thus we argue that research into specific areas, including dynamic policy refinement, dynamic policy conflict detection and resolution, policy interoperability among domains, and inter-domain policy negotiation, must be carried ou

Daidalos Security Framework for Mobile Services

Mobility is now the central focus of the lives of European citizens in business, education, and leisure. This will be enriched by pervasiveness in the future. The Daidalos vision is to seamlessly integrate heterogeneous network technologies that allow network operators and service providers to offer new and profitable services, giving users access to a wide range of pervasive, personalised voice, data, and multimedia services. This paper discusses the security issues that need to be addressed to make Daidalos a real viable solution for future pervasive mobility. Issues include among others privacy & identity management, secure protocols, distributed key management, security in ad hoc networks

Developing a Pervasive System for a Mobile Environment

The problem of personalised context aware service selection and composition is an important research area that is addressed within the pervasive service platform being developed by the Daidalos project. This paper briefly outlines the scenarios used and the overall platform architecture that underpin this development. It then describes the approach used to select service components and compose them to produce a composite service that satisfies an individual user’s needs and takes account of changing context. It also discusses the interaction between personalisation and context management,. These ideas have been extensively tested and demonstrated with the scenarios. In the second phase of Daidalos, the developments will be generalised and subjected to wider testing

Pervasive Service Platform (PSP): Facilitating Pervasive Services

Pervasive computing is a new and emerging technology. The concept of pervasiveness and its deployment into reality are still not well aligned. This is because the vision of pervasiveness is a highly complex area that encompasses a large number of issues. The real vision of pervasiveness will never become a reality if everyone involved needs to repeatedly address all the issues involved in the concept. This paper focuses on the DAIDALOS Pervasive Service Platform (PSP) as an enabler of pervasive services. DAIDALOS is an EU Framework Programme 6 Integrated Project with 46 multinational partners from both the industry and academia. The paper details the strategy employed in DAIDALOS to facilitate Service Providers to offer pervasive services on top of the PSP. It argues that pervasiveness should be provided to Service Providers as part of the platform, instead of requiring pervasiveness to be totally embedded in the services themselves. This approach consequently opens up the service provision market to more players, driving the idea of a truly pervasive world. The paper gives an overview of the DAIDALOS platform as a pervasive service enabler, detailing how it facilitates pervasiveness by removing most of the work from the Service Providers themselves

Genetic similarity of biological samples to counter bio-hacking of DNA-sequencing functionality

We present the work towards strengthening the security of DNA-sequencing functionality of future bioinformatics systems against bio-computing attacks. Recent research has shown how using common tools, a perpetrator can synthesize biological material, which upon DNA-analysis opens a cyber-backdoor for the perpetrator to hijack control of a computational resource from the DNA-sequencing pipeline. As DNA analysis finds its way into practical everyday applications, the threat of bio-hacking increases. Our wetlab experiments establish that malicious DNA can be synthesized and inserted into E. coli, a common contaminant. Based on that, we propose a new attack, where a hacker to reach the target hides the DNA with malicious code on common surfaces (e.g., lab coat, bench, rubber glove). We demonstrated that the threat of bio-hacking can be mitigated using dedicated input control techniques similar to those used to counter conventional injection attacks. This article proposes to use genetic similarity of biological samples to identify material that has been generated for bio-hacking. We considered freely available genetic data from 506 mammary, lymphocyte and erythrocyte samples that have a bio-hacking code inserted. During the evaluation we were able to detect up to 95% of malicious DNAs confirming suitability of our method.publishedVersionPeer reviewe
