Abstract. Let A and B denote cryptographic primitives. A (k, m)robust A-to-B combiner is a construction, which takes m implementations of primitive A as input, and yields an implem...

In a large sensor network, in-network data aggregation, i.e., combining partial results at intermediate nodes during message routing, significantly reduces the amount of communic...
