Possible attacks on and countermeasures for secure multi-agent computation

In this paper we improve the model for secure multi-agent
computation proposed by Endsuleit and Mie. We apply a recent
protocol from Hirt and Maurer for secure multi-party computation
to build Alliances of n agents that solve a common task. The
protocol used is very efficient with a communication load of
O(n^2 m) (where m is the number of multiplications). All
computations within the Alliance are robust as less than n/3
agents are corrupted at the same time.
