A trust-based secure routing protocol for multi-layered satellite networks

In order to meet the demand of security mechanism for the multi-layered satellite networks routing protocols, we introduce an ID-based sign scheme, and design a secure routing protocol for multi-layered satellite networks. The protocol is proposed based on the clustering-based multi-layered satellite networks architecture, and the combination of trust mechanism and authentication mechanism. The analysis shows that the protocol can resist several common attacks, and improve the routing security of the satellite networks.
