A Secure Routing Protocol Based on Certificateless Signcryption for Satellite Networks

The article introduces a certificateless signcryption scheme targeting the problem of lacking of security mechanism in the routing of satellite networks, and designs a secure routing protocol suitable for the satellite networks. The proposed protocol avoids complicated management in the certificate mechanism and bypasses the key escrow problem in the identity-based cryptography using the certificateless cryptography and signcryption. The analysis shows that the new protocol can resist several common attacks, effectively improve the security of the satellite networks routing.
