Modeling and simulation often require different tools for specialized purposes; which increase the motivation to use co-simulation. Since physical models often are describing enterprises’ primary know-how; there is a need for a sound approach to securely perform modeling and simulation. This paper discusses different possibilities from a security perspective; with focus on secure distributed co-simulation over wide area networks (WANs); using transmission line modeling (TLM). An approach is outlined and performance is evaluated both in a simulated WAN environment; and for a real encrypted co-simulation between Sweden and Australia. It is concluded that several parameters affect the total simulation time; where especially the network delay (latency) has a significant impact.
