Virtualization of Remote Devices and Services in Residential Networks

2009

Lately solutions for remote access for residential services have been proposed. However, these solutions require modifications to the service controllers. In addition, remote access adds complexity to the client application. We propose here a solution for decoupling remote access from the client itself with an entity that creates virtual instances of remote services in a local network. Thereby, clients will be able to discover the virtual instance and use it. Moreover, client applications do not need to distinguish between local and remote services hence reducing complexity.

FoSBaS: A bi-directional secrecy and collusion resilience key management scheme for BANs

2012

Body Area Network (BAN) consists of various types of small physiological sensors, transmission modules and low computational components and can thus form an E-health solution for continuous all-day and any-place health monitoring. To protect confidentiality of collected data, a shared group key is usually deployed in a BAN, and consequently a secure communication group is generated. In this paper, we propose a bi-directional security and collusion resilience key management scheme for BAN, referred to as FoSBaS. Detailed analysis shows that the scheme can provide both forward security and backward security and resist against collusion attacks. Furthermore, the FoSBaS is implemented on a Sun …

Security Threats in ZigBee-Enabled Systems: Vulnerability Evaluation, Practical Experiments, Countermeasures, and Lessons Learned

2013

In this paper, two practical attacks against ZigBee security are proposed and the latter one is also carried out in our laboratory environment. The attack scenarios are based on utilizing several vulnerabilities found from the main security components of ZigBee technology. The first attack is based on sabotaging the ZigBee End-Device by sending a special signal that makes it wake-up constantly until the battery runs out. The second attack is based on exploiting the key exchange process in ZigBee when using the Standard Security level defined by the ZigBee specification: we also demonstrate with experimental figures that attacks against ZigBee-enabled devices become practical by using our at…

Autonomy, Heterogeneity and Trust in Mobile P2P environments

2007

Mobile P2P environments are emerging as a result of rapid expansion of portable terminals that are able to establish direct wireless communication links among themselves. These kinds of terminals are under the control of persons and allowing interactions between their terminals is subject to trust between the individuals and their desire to preserve various aspects of autonomy against each other. In this paper we relate the concepts of node autonomy, heterogeneity and trust with each other, defining also numeric measures for them. We also investigate what kind of interactions (such as transactions, file exchanges) are possible at certain heterogeneity, autonomy and trust level between the t…

Location-Aware Mobile Intrusion Detection with Enhanced Privacy in a 5G Context

2010

Published version of an article from the journal: Wireless Personal Communications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11277-010-0069-6 The paper proposes a location-aware mobile Intrusion Prevention System (mIPS) architecture with enhanced privacy that is integrated in Managed Security Service (MSS). The solution is envisaged in a future fifth generation telecommunications (5G) context with increased but varying bandwidth, a virtualised execution environment and infrastructure that allows threads, processes, virtual machines and storage to be migrated to cloud computing services on demand, to dynamically scale performance and save power. 5G mob…

Mobile Electronic Commerce: Emerging Issues

2000

There are many definitions for Mobile Electronic Commerce (M-Commerce). We define M-Commerce as any type of transaction of an economic value having at least at one end a mobile terminal and thus using the mobile telecommunications network. The Wireless Application Protocol (WAP) plays an important role in m-commerce by optimizing Internet standards for the constraints of the wireless environment and thus bridging the gap between Internet and mobile world. Mobile Network Operators can play a major role in m-commerce by being strategically positioned between customers and content/service providers. In this paper we investigate the roles the operator can play in m-commerce and discuss respecti…

Auxilum Medicine: A Cloud Based Platform for Real-Time Monitoring Medical Devices

2015

Nowadays, time is a very valuable resource and can make the difference between life and death. Having knowledge about this fact we decided to deal with one of the most important aspects of contemporary medicine, EMS (emergency medical services) response time. Modern systems that encourage intelligent communication methods between medical devices and doctors are a must in ubiquitous health care environments. Auxilum Medicine fosters a triple-win situation regarding the relationship between medical institutions, doctors and patients. Emergency patients should be treated with utmost care because their life is hanging by a thread if nobody is present to take immediate action. We are presenting …

ITIL Implementation: The Role of ITIL Software and Project Quality

2012

This research will investigate the implementation status of the Information Technology Infrastructure Library (ITIL) reference processes and the influence of ITIL software quality and ITIL project quality on implementation status. The paper analyzes data from a survey of 160 Nordic companies.

The United Nations and the European Union

2019

The European Union (EU) and the United Nations (UN) are expressions of a rules-based global order. The EU has enshrined support to the UN in its security strategies, and its priorities indicate an engagement in a wide range of UN programs and activities to maintain the rules-based order and adapt it to face internal and external challenges. The EU and its member states are the largest contributors to the UN budget. Following the adoption of the Lisbon treaty, the EU has increased its representation at the UN, gaining enhanced observer status in the General Assembly. However, because of the intergovernmental nature of the forum, only its member states have the right to vote. This has led sch…
