RERUM: REliable, Resilient and secUre IoT for sMart city applications

In the project RERUM we will develop, evaluate, and trial an architectural framework for dependable, reliable, and secure networks of heterogeneous smart objects (Internet of Things or "IoT") supporting innovative Smart City applications. The framework will be based on the concept of "security and privacy by design", addressing the most critical factors for the success of Smart City applications.

RERUM is funded for 3 years under the FP7-SMARTCITIES-2013 and started in 1. September 2013.

Main RERUM Objectives

The ultimate goal of RERUM is to allow IoT to become the fundamental enabler towards a truly Smart City, having the citizen at the centre of attention. The key objectives of RERUM can be summarized as:
  • Identify common threats and open security/privacy/reliability issues in existing IoT frameworks for Smart City applications.
     
  • Develop an architectural framework for the interconnectivity of a large number of heterogeneous smart objects based on the concept of “security, privacy and reliability by design”.
     
  • Embed security and reliability on the hardware smart objects, providing reliable, self-managed, robust and context-aware communications minimizing energy consumption.
     
  • Investigate the adaptation of Cognitive Radio (CR) technology in smart objects to minimize wireless interference and ensure the “always connected” concept.
     
  • Evaluate the performance of the framework in two real-world Smart City environments: Tarragona and Heraklion.
     

The work will be driven by the requirements of the target Smart City applications and by an assessment of the threats and open security issues in existing IoT frameworks for smart cities.

RERUM considers four smart city applications to drive the requirements for system development and these will be developed and tested in the trials:

  • Outdoor 1: Smart Transportation.
     
  • Outdoor 2: Environmental monitoring.
     
  • Indoor 1: Home energy management.
     
  • Indoor 2: Comfort quality monitoring.
     

The work will also follow an iterative approach starting from an initial definition of the architecture and the respective mechanisms that will be refined as the work progresses in order to mitigate any identified issues.

The key scientific areas of focus of the project are:

  • Security, privacy and trust in IoT-based smart objects.
     
  • Information security and privacy in smart city applications.
     
  • Reliable interconnectivity of smart objects based on Cognitive Radio.
     
  • Energy efficient operation of smart objects.
     
  • Performance and scalability analysis of IoT.
     
  • Smart City applications.

Role of University of Passau in RERUM

Our chair is leading RERUM's security workpackage "System & Information Security and Trust" and Prof. Joachim Posegga is appointed scientifical and technical co-cordinator. The foreseen main contributions of the University of Passau are in the following areas:

  • Security Evaluation: University of Passau will contribute to the definition of the use-cases, as well as to the evaluation of the vulnerabilities, threats and risks of the Smart City applications.
     
  • Trust: Design integrity and authenticity mechanisms for IoT so that they allow delivering "trustworthy information" and still allow privacy enhancing technologies to preserve the smart cities' citizens' privacy. University of Passau will aid developing a model for the trustworthiness of informatio We will allow to include the integrity verification results in the model of the IoT’s trustworthiness.
     
  • Privacy: In particular we will apply and enhance malleable signatures, thus enabling smart city applications to verify the authenticity of signed sensor data even if for privacy personally identifying information has been removed on behalf of the citizen.
     

The twelve project partners in RERUM are: EURESCOM GMBH (DE), Advancare SL (ES), ATOS SPAIN SA (ES), Foundation for Research and Technology Hellas (GR), SIEMENS AG (DE), CYTA Hellas Tilepikoinoniaki AE (GR), University of Bristol (UK), Ajuntament de Tarragona (ES), Linkopings Universitet (SE), Heraklion Municipality (GR), SIEMENS SRL (RO) and Universitat Passau (DE).
