Abstract: To solve the problem that most route protocols lack secure mechanism, the route secure scheme is provided following trust. The trust evaluation model is given based on satellite network routing behavior. Trust metric is used to limit path selection. Route load balance is the goal of optimization. By improving existing route protocol, an on-demand secure routing protocol for satellite network is formed. The analysis result shows that it can resist a lot of inside attacks.

Key words: trust evaluation, route security, load balance, time window
