Privacy Guarantees for Cloud-based State Estimation using Partially Homomorphic Encryption. (arXiv:2111.04818v2 [cs.CR] UPDATED)
cs.CR updates on arXiv.org arxiv.org
The privacy aspect of state estimation algorithms has been drawing high
research attention due to the necessity for a trustworthy private environment
in cyber-physical systems. These systems usually engage cloud-computing
platforms to aggregate essential information from spatially distributed nodes
and produce desired estimates. The exchange of sensitive data among semi-honest
parties raises privacy concerns, especially when there are coalitions between
parties. We propose two privacy-preserving protocols using Kalman filter and
partially homomorphic encryption of the measurements and estimates while
exposing …
