  • SAFERtec (2017 - 2019)

    Security Assurance Framework for Networked Vehicular Technology (Horizon 2020)

    SAFERtec is a European Union’s Horizon 2020 research and innovation programme under grant agreement No 732319.

    Modern vehicles are becoming increasingly capable of establishing connectivity that allows the rich-information exchange between them and road infrastructure units. The so-called ‘connected-vehicles’ paradigm can bring-about an enormous potential towards safer transportation only if the involved security needs against a variety of ‘new’ threats are confidently satisfied.

    The SAFERtec project seeks to in-depth explore the involved vulnerabilities of connected vehicles, apply innovative techniques for attack modeling, experimentally validate the quantification of security assurance levels and also contribute to relevant standards. With a total budget of 3.8 million Euros funded by the European Commission, 9 partners of industrial, SME and academic profile coming from 6 different countries join their expertise to contribute to the vision of introducing a security assurance framework tailored for future networked vehicular technology.

    The area of Automotive technology is one of the most prominent to have experienced the trend of developing a plethora of (hardware and software) modules provided by numerous 3rd party entities and having them integrated into an ICT products of advanced functionality.

    The emerging Connected Vehicles paradigm shift is expected to dramatically change the way drivers interact with their vehicle and improve significantly traffic safety and efficiency. While introducing new electronic systems, sensors, embedded devices, services, connectivity to the internet, navigation, safety and mobile applications a complex new eco-system is build including among others new vulnerabilities and risks.

    Vehicle manufacturers (OEMs), infrastructure providers (cloud, telecom), third parties systems and component providers as well as application and service providers are facing immense challenges towards the design, development, implementation, integration and operation of highly connected ICT components, services and applications for Connected Vehicle systems. All these new possibilities increase the complexity and risk with potential fatal consequences if security, safety and privacy are not adequately addressed.

    What is then of the utmost importance is to establish links of trust to foster innovation, societal acceptance and market uptake. Formal procedures for assuring and certifying products, systems and services adherent to relevant standards and practices, is one relevant key enabler. The SAFERtec concept is based on those key findings and thus aims to propose an Assurance Framework for enhancing trust by providing formal methods, processes, techniques and tools that will facilitate the assurance of security, safety and privacy.

    SAFERtec will design an agile security assurance framework tailored for V2I Automotive settings and evaluate the results of its application relying both on careful comparison with current standardized frameworks, best practices and recommendations but also experimentation means. A Connected Vehicle System (i.e., vehicle connected with infrastructure) developed and integrated by the consortium partners will cover a wide range of the respective stakeholders (OEM, On board units, SW, application and service providers). SAFERtec will then incorporate the designed framework in a modular and extendable Assurance Framework Toolkit to provide estimations of security assurance levels for a range of automotive scenarios.

  • MAESTRO (2004 - 2005)

    Mobile Application and Services based on Terrestrial and Satellite Interworking

    MAESTRO-FP6-IST-2003.

    The European satellite community is proceeding with great thrust towards the development of the innovative Satellite Digital Multimedia Broadcast (SDMB) concept, which will pave the way for an effective Satellite and Terrestrial network convergence. The SDMB system aims at complementing mobile networks with broadcast and multicast capabilities for a spectrum effective delivery of multimedia services on mobile devices. Taking advantage of the natural assets of satellite systems and of the full interoperability with terrestrial standards, the SDMB system will facilitate the successful deployment of UMTS, minimise geographical discrimination and foster multimedia usage adoption inEurope, effectively bridging the digital divide. Numerous studies, lead by the European Commission (e.g. MODIS, SATIN and RELY IST FP5 projects), the European Space Agency and National space agencies have contributed to the emergence of the SDMB concept, to secure the overall feasibility of the proposed innovations, to improve regulatory opportunities and to assess the market benefits.

    Starting from this strong European knowledge base, the MAESTRO Integrated Project will proceed to specify, implement and validate the critical features of an SDMB system architecture. It aims at the highest possible degree of interoperability with terrestrial infrastructures with the objective to maximise its competitive assets and the underlying business rationale. Based on a solid consortium that achieves a balanced participation of terrestrial and satellite actors, the MAESTRO project will contribute to ensure wider adoption, broader availability of 3G and beyond 3G applications and services. In this perspective, MAESTRO is a unique opportunity for satellite communications to assure their role in the Generalised Access Network infrastructure, to foster the growth of the eEconomy and to improve European citizens welfare and safety.

  • COST 273 (2001 - 2005)

    Towards Mobile Broadband Multimedia Networks

    The objectives of this Action were as follows:

    – To increase the knowledge on the radio aspects of mobile broadband multimedia networks by exploring and developing new methods, models, techniques;
    – To play a supporting role in the mobile communication area;
    – To contribute to the deployment of systems which are very close to the completion of their standardisation phase.

    Results were achieved in the areas of Radio System Aspects, Propagation and Antennas, and Radio Network Aspects. The management effort required for directing such a large and wide-ranging project is substantial. In fact, it would be a worthwhile effort to try and analyze the management of the project, which could be used as the management model for many other virtual organisations. It is also impressive that the various reports and papers produced by the consortium were amalgamated in a coherent treatise, ultimately leading to a well-focused book, published by Elsevier, which compiles a whole host of valuable ideas and hence substantially contributes towards the international scientific debate on the next generation of wireless systems. In particular, the Action introduced new analytical MIMO channel models (as input to ITU, ETSI and 3GPP). Similarly to the now classic COST 207 channel models, this COST 273 MIMO model is likely to find its way into numerous future studies. This single result alone would have justified the modest cost of this comprehensive research programme. Further achievements realised by Working Groups and also by the Sub-Working Groups were:

    – Handset measurements (as input to ITU, ETSI and 3GPP);
    – Channel measurements; – Mobile radio access network reference scenarios;
    – Exchange of information, models and measured data among participating institutes.

    The research activities carried out in the Action contributed to the keeping of the European leading role in mobile and wireless communications. The Action had impact on maintaining, and even increasing, the industrial competitiveness of European industry in the mobile communication area.

  • SafeIT - Wearable systems for the safety and wellbeing applied in security guards (2020 - 2023)

    Research-Create-Innovate 2nd Cycle, National Strategic Reference Framework (NSRF) 2014-2020

    Wearable devices and augmented reality are rapidly evolving and are particularly applicable in the service sector, such as safety, health, education, etc. In the field of security services, in particular the no-contact / lone security positions, device handler technology can offer innovative services. In particular, it can further secure the individual protection of staff in existing security services and improve their mental concentration and perceptual capacity, which assists in decision-making. Portable devices can detect the presence, biometric data of the guardian, and many additional elements that are useful both in the service they perform and the personal safety of the workers.

    The goal of the project is to develop systems and applications that will receive and process data from smart wearable to record biometric data for the purposes of health and vital safety monitoring, positioning and presence / commencement / ending of the shift, direct notification and other required services, such as indications of danger, attack, etc. These devices will automatically wirelessly connect with additional equipment (ambient sensors and positional beacons) and their data will be combined with the cameras data. Systems of Augmented / Mixed reality will also be developed in addition to simply record and track signals, more effectively manage the data from incident management center operators and supporting decision-making by the end user (guardian).

    Due to the variety of data to be transmitted and stored, a combination of modern signal processing and machine learning techniques is needed through the creation of a knowledge base. The latter will be shaped by the data collected per event. There will also be use of pioneering security techniques which combine multi-parametric authentication, such as the use of biometric elements (something the user is) with equipment components (somethingthe user has), which will be physically resistant to cloning, that is to say they will exhibit structural features that will make them unique. Some of the most important issues that will be addressed in the project are the data transmission security and the use of blockchain technology for secure data storage (protection against unauthorized data alteration, PUF assisted encryption), as well as the use of security technologies to protect personal data (use of nicknames and aliases, PUF reciprocal authentication). In the strand of augmented reality, the technological innovation that the project introduces is multidimensional. More specifically, this project is the first national effort to develop an integrated augmented/mixed reality platform that acts on both the field and the control center. The development of AR interfaces for managing information in the field of security services is an innovation of the project. Also, the development of ergonomic interfaces based on the geometric representation of the area of interest combined with the use of maps in an augmented reality environment is another innovation the project aspires to introduce. Finally, all applications that will be deployed will respect the privacy of users by complying to the requirements of innovative and academically recognized methodologies, while ensuring all the technical and organizational requirements set by the new General Data Protection Regulation 2016/679 (GCC-GDPR) are met.
