On Secure Consensus Information Fusion over Sensor Networks
2007
2007 IEEE/ACS International Conference on Computer Systems and Applications
Preserved Fulltext
As an example, two secure consensus averaging methods are formulated according to BIFF. ...
In quest for a method to make information fusion possible while preserving the mutual confidentiality and anonymity of the fused information even in case of collusion of the malicious nodes, we propose ...
We divide distributed information fusion into two main categories: consensus information fusion or consensus fusion in short and, non-consensus information fusion. ...

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. ...
