Distributed Metrological Sensors managed by a secure Cloud-Infrastructure

In recent years Cloud Computing has seen a lot of improvement in terms of security, stability and maturity thus it should be able to meet the demands and requirements of critical infrastructures and well-regulated areas. This paper focuses on a secure and modular approach for a cloud infrastructure that conforms to the Measuring Instrument Directive of the European Union while preserving the advantages and benefits of cloud computing for corporations and consumers. The legitimate, secure and protected flow of measurement data are key challenges of this work by utilizing homomorphic encryption the authors respond to these challenges and counter the main attack vectors of cloud computing at the same time.
