Efficient and robust data aggregation using untrusted infrastructure
Marek Klonowski, Michał Koza, Mirosław Kutyłowski · 2013
We present two protocols for data aggregation in networks consisting of many subsystems run by different and potentially adversarial parties. In such a case the messages from the nodes of a subnetwork are aggregated and transmitted to the sink over intermediate nodes which are not controlled by the subnetwork, and which potentially are influenced by an adversary. The adversary aims at changing the result of computations and/or learning the data processed by the stations of the subnetwork.
