Cyber security is always a main concern for critical infrastructures and nation-wide safety and sustainability. Thus, advanced cyber ranges and security training is becoming imperative for the involved organizations. This paper presets a cyber security training platform, called THREAT-ARREST. The various platform modules can analyze an organization...

Interoperability stands for the capacity of a system to interact with the units of another entity. Although it is quite easy to accomplish this within the products of the same brand, it is not facile to provide compatibility for the whole spectrum of the Internet-of-Things (IoT) and the Linked Data (LD) world. Currently, the different applications...

Vehicular Ad hoc NETworks (VANET) are becoming popular due to the emergence of the Internet of Things and ambient intelligence applications. In such networks, secure resource sharing functionality is accomplished by incorporating trust schemes. Current solutions adopt peer-to-peer technologies that can cover the large operational area. However, the...

Achieving Security, Privacy, Dependability and In-teroperability (SPDI) is of paramount importance for the ubiquitous deployment and impact maximization of Internet of Things (IoT) applications. Nevertheless, said requirements are not only difficult to achieve at system initialization, but also hard to prove and maintain at run-time. This paper hig...

Semantic interoperability is the designed property where various systems can interact with each other and exchange data with unambiguous, shared meaning. This enables knowledge discovery, machine computable reasoning and federation of different information systems. Traditionally, technologies from the Semantic Web are adapted in order to capture th...

The vast amount of connected devices on the Internet of Things (IoT) creates an enormous potential for new applications, by leveraging synergies arising through the convergence of consumer, business and industrial Internet, and creating open, global networks connecting people, data, and "things". In this context, the SEMIoTICS project aims to devel...

Day-by-day modern circular economy (CE) models gain ground and penetrate the traditional business sectors. The Internet of Medical Things (IoMT) is the main enabler for this interplay of CE with healthcare. Novel services, like remote sensing, assisting of elder people, and e-visit, enhance the people's health and convenience, while reducing the pe...

Botnets constitute nowadays one of the most dangerous security threats worldwide. High volumes of infected machines are controlled by a malicious entity and perform coordinated cyber-attacks. The problem will become even worse in the era of the Internet of Things (IoT) as the number of insecure devices is going to be exponentially increased. This p...

A popular application of ambient intelligence systems constitutes of assisting living services on smart buildings. As intelligence is imported in embedded equipment the system becomes able to provide smart services (e.g. control lights, airconditioning, provide energy management services etc.). IoT is the main enabler of such environments. However,...

Smart interconnected devices, including Cyber-Physical Systems (CPS), permeate our lives and are now an integral part of our daily activities, paving the way towards the Internet of Things (IoT). In the industrial domain, these devices interact with their surroundings and system operators, while often also integrating industrial cloud applications....

Computing devices already permeate working and living environments, while researchers and engineers aim to exploit the potential of pervasive systems in order to introduce new types of services and address inveterate and emerging problems. This process will lead us eventually to the era of urban computing and the Internet of Things (IoT). However,...

Computing devices permeate working and living environments, affecting all aspects of modern everyday lives; a trend which is expected to intensify in the coming years. In the residential setting, the enhanced features and services provided by said computing devices constitute what is typically referred to as a “smart home”. However, the direct inte...

Ubiquitous devices comprising several resource-constrained sensors & actuators while having the long desired Internet connectivity, are becoming part of many solutions that seek to enhance user's environment smartness and quality of living. Their intrinsic resource limitations however constitute critical requirements, such as security, a great chal...

As computing becomes ubiquitous, researchers and engineers aim to exploit the potential of the pervasive systems in order to introduce new types of services and address inveterate and emerging problems. This process will, eventually, lead us to the era of urban computing and the Internet of Things; the ultimate goal being to improve our quality of...
