Henrich C. Pöhls will present the results of his joint work with Markus Karwe from University of Freiburg on Redactable Signatures to Control the Maximum Noise for Differential Privacy in the Smart Grid.
The Smart Grid is currently developed and fundamental security requirements like integrity and origin authentication need to be addressed while minimising arising privacy issues. This paper balances the opposing goals: On one hand, we mitigate privacy issues raised by overly precise energy consumption values via data perturbation mechanisms, e.g., add noise. On the other hand the paper describes how to limit the noise’s range and keep a verifiable level of integrity of consumption values from the Smart Metering Gateway by facilitating a redactable signature.
The second Open NESSoS / EIT ICT Labs Workshop on Smart Grid Security will take place in the Technical University of Munich, in the centre of the city, on the 26th of Feb, 2014 in the context of the International Symposium on Engineering Secure Software and Systems (ESSoS’14). The Workshop is sponsored jointly by the Network of Excellence on Engineering Secure Future Internet SW (NESSoS) and the action line smart energy systems of the EIT ICT Labs.
