Collaboratively exchanging warning messages between peers while under attack

Secure Multi-party Computation (MPC) allows a secure joint cooperation within a distributed group of peers. In this paper we investigate an extended Secure MPC solution that allows mutual information exchange and distribution of warnings among a group of participating peers within an information sharing network. The implementation of this MPC solution is deployed in a peer-to-peer network. This paper evaluates the performance of the implementation based on two scenarios that stress the network load and thus simulate the implementation under attack. Using a network simulation provides a connection between a simulated network model and real systems by use of System-in-the-loop (SITL) technology for the validation of the considered MPC implementation.
