Smart-grid developments have paved way for sustainable energy infrastructures moving towards decentralized energy trading. Energy sources functioning as smart agents, carry out energy trading based on their energy surplus or deficiency. Two critical aspects should be addressed while implementing decentralized energy trading; Buyers and sellers (par...

The Internet of Things (IoT) is the novel paradigm of connectivity and the driving force behind state-of-the-art applications and services. However, the exponential growth of the number of IoT devices and services, their distributed nature, and scarcity of resources has increased the number of security and privacy concerns ranging from the risks of...

Recent advancements in the Internet of Things (IoT) has enabled the collection, processing, and analysis of various forms of data including the personal data from billions of objects to generate valuable knowledge, making more innovative services for its stakeholders. Yet, this paradigm continuously suffers from numerous security and privacy concer...
Article
Full-text available
The Internet of Things has facilitated access to a large volume of sensitive information on each participating object in an ecosystem. This imposes many threats ranging from the risks of data management to the potential discrimination enabled by data analytics over delicate information such as locations, interests, and activities. To address these...

Application of trust principals in internet of things (IoT) has allowed to provide more trustworthy services among the corresponding stakeholders. The most common method of assessing trust in IoT applications is to estimate trust level of the end entities (entity-centric) relative to the trustor. In these systems, trust level of the data is assumed...
Conference Paper
Trust in Social Internet of Things has allowed to open new horizons in collaborative networking, particularly by allowing objects to communicate with their service providers, based on their relationships analogy to human world. However, strengthening trust is a challenging task as it involves identifying several influential factors in each domain o...
Conference Paper
Full-text available
This paperpresents the trust concept, features, key characteristics and challenges for trusted ICT infrastructures and services based on ITU-T activities. It also discusses several technical issues for trust provisioning in ICT infrastructures and services. It then outlines ideas for an effort to find viable solutions to trust related problems whil...

Internet of Things defines a large numberof diverse entities and services which interconnect with each other and individually or cooperatively operate depending on context, conditions and environments,producea huge personal and sensitive data. In this scenario, the satisfaction of privacy, security and trust plays a critical role in the success of...

We are interested in the security of the MPLS Transport Profile (MPLS-TP), in the context of smart-grid communication networks. The security guidelines of the MPLS-TP standards are written in a complex and indirect way, which led us to pose as hypothesis that vendor solutions might not implement them satisfactorily. To test this hypothesis, we inve...

We are interested in the security of the MPLS Transport Profile (MPLS-TP), in the context of smart-grid communication networks. We find security issues with the Cisco implementation of two MPLS-TP OAM (Operations, Administration, and Maintenance) proto-cols: bidirectional forwarding detection (BFD) and protection state coordination (PSC). BFD is us...

Orthogonal frequency division multiplexing with offset QAM (OFDM/OQAM) modulation scheme, more commonly known as filter bank multicarrier (FBMC), has received greater attention recently, due to its spectral efficiency compared to standard OFDM. However, intrinsic interference in FBMC causes a negative effect on the system performance depending on the...
Conference Paper
Full-text available
Filter Bank Multicarrier (FBMC) transmission sys- tem received much attention recently as an alternative mul- ticarrier modulation (MCM) technique compared to OFDM due to its higher spectral efficiency and less susceptibility to synchronization errors. However, the degradation of performance in multi stream FBMC is comparatively high even with perfe...

Antenna correlation is generally viewed as an obstacle to realize the desired performance of a wireless system. In this article, we investigate the performance of partial relay selection in the presence of antenna correlation. We consider both channel state information (csi)-assisted and fixed gain amplify-and-forward (AF) relay schemes. The source...

Project
Wise-IoT is a collaborative project between Europe and Korea. From the EU side, it is funded under the H2020 framework program for research of the European Commission. It aims at deepening the interoperability and interworking of IoT existing systems. Use case driven, the project uses the experiences available in the consortium to build a comprehensive mediation framework that can be used between various IoT systems.
