Consensus with Preserved Privacy against Neighbor Collusion [article]

Silun Zhang, Thomas Ohlson Timoudas, Munther Dahleh
2020 arXiv   pre-print
This paper proposes a privacy-preserving algorithm to solve the average consensus problem based on Shamir's secret sharing scheme, in which a network of agents reach an agreement on their states without  ...  Another virtue of this work is that such a method can protect the network consensus procedure from eavesdropping.  ...  As the information can be reconstructed entirely from a certain specified number of shares, the information injected into the network for each agent is still intact but in a confidential way.  ...
