Query: Scalable and Secure Aggregation in Distributed Networks   We consider the problem of computing an aggregation function in a
\emph{secure} and \emph{scalable} way. Whereas previous distributed solutions
with similar security guarantees have a communication cost of $O(n^3)$, we
present a distributed protocol that requires only a communication complexity of
$O(n\log^3 n)$, which we prove is near-optimal. Our protocol ensures perfect
security against a computationally-bounded adversary, tolerates
$(1/2-\epsilon)n$ malicious nodes for any constant $1/2 > \epsilon > 0$ (not
depending on $n$), and outputs the exact value of the aggregated function with
high probability.
