Cyber Security for Wireless Semantic (SCADA/DCS) Systems
2016
International audience; Supervisory Control and Data Acquisition and Distributed Control Systems named (SCADA/DCS) have played a key role in the design of modern power smart applications, particularly in the automatic management of real time energetic platforms. In this work, we present a semantic cyber security vulnerabilities add to classic one, with the use of semantic embedded application in smart devices in semantic wireless (SCADA/DCS) systems, focusing on the semantic attacks. In this work, we present a new security semantic wireless protocol as a secure communication support for these modern semantic wireless systems named (ZIGBEE/SOAP/SECURITY), obtained by the combination between …
Hand-Held texting is less distracting than texting with the phone in a holder: anyway, don't do it
2015
We studied the effects of texting while driving and the effects of mobile phone position (hand-held, holder) on drivers' lane-keeping performance, experienced workload, and in-car glance durations in a motion-platform driving simulator with 24 participants. Overall, we found the known negative effects of texting on lane-keeping performance, workload, and visual attention on road, suggesting that texting on the road in any manner is not risk-free. As a novel finding, we found that hand-held texting led to fewer lane-keeping errors and shorter total glance times off road compared to texting with the phone in a holder. We suggest the explanation is that the drivers had considerably more experi…
Decentralized Synchronization for Zigbee wireless sensor networks in Multi-Hop Topology
2010
Abstract The most effective solution for energy saving in low-rate wireless sensor networks is maintaining each node in a doze state as long as possible. In order to guarantee network connectivity, the intervals at which the network sensors are turned on and off have to be coordinated. We analyze the Zigbee MAC performance in sensor networks deployed in multi-hop topologies. For this networks, critical inefficiencies can arise due to transmissions performed by hidden nodes. We evaluate the impact of different synchronization schemes on the network performance, both in terms of network capacity and in terms of energy consumption. We show how the synchronization function can be opportunistica…
Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
A unified radio control architecture for prototyping adaptive wireless protocols
2016
Experimental optimization of wireless protocols and validation of novel solutions is often problematic, due to limited configuration space present in commercial wireless interfaces as well as complexity of monolithic driver implementation on SDR-based experimentation platforms. To overcome these limitations a novel software architecture is proposed, called WiSHFUL, devised to allow: i) maximal exploitation of radio functionalities available in current radio chips, and ii) clean separation between the logic for optimizing the radio protocols (i.e. radio control) and the definition of these protocols.
Introduction to the enterprise content management minitrack
2003
Enterprise content management (ECM) focuses on the management of textual and multimedia content across and between enterprises, emphasizing the coexistence of technical and social aspects within the content management. Methods and techniques applicable for managing textual and multimedia information with all sizes of content units, ranging from XML and database structures through web pages and documents to document collections, are studied as well as approaches focusing on specific content structures. In a piece of ECM research, multiple of the perspectives may be covered, or one of the perspectives is chosen as the major view to the area: • the technical perspective including the developme…
Introduction to the Enterprise Content Management and XML Minitrack
2005
Content management in contemporary enterprises concerns a variety of information resources: documents in different forms, databases, and metadata such as ontologies, annotations, and indexes. XML and the web are important technologies used to support both resource integration and distribution.
An investigation of the impacts of some external contextual factors on ERP systems success assessment: a case of firms in Baltic-Nordic region
2006
Enterprise Resource Planning (ERP) systems are among the largest information systems (IS) investments made by firms, and the use of such systems is spreading globally. Many researchers have discussed their adoption and implementation, few have investigated the impact of external contextual factors on the success of such technologies in adopting firms. This study aims to fill this gap in research by examining the effects of three external contextual factors, i.e., industry type, industry climate, and national economic climate on ERP success assessment. We obtained data from Estonia and Finland and our analysis shows that industry and national economic climates have significant relationships …
Banks Digitalization - A Challenge for the Romanian Banking Sector
2019
Abstract The banking system has undergone several transformations since its beginning up to now, some as a result of adapting to customers’ requirements that have become increasingly sophisticated, and others as a result of the economic and political contexts that have passed, which again – have required its adaptation. Regardless of the situation, the banks have undergone a large digitization process, a process that is now in progress and which in the coming years can cause a significant change in the banking we knew about 10-15 years ago. Through this paper, I propose to analyse the situation of the banking system in terms of adapting to these challenges, at the level of Romania, in the c…
Human Security versus Human Development - Behavioristic Approach
2016
Abstract Recent terrorist attacks in Brussels, Paris and Istanbul, are shaking a world bewildered of daily fear of violence, while the contemporary consumer has to deal with the “new wars” emerging in the context of the current socio-economic and political context. The issue is especially thorny since, most of the times, the “enemy” the citizens must face is unknown, not only when it comes to terrorist attacks, but also when dealing with the question of the “enemy” in foods purchased for consumption (food security) or the security of personal data when accessing and using the Internet (cyber security). Consequently, this paper attempts to highlight the way in which the safety and security n…
