Abstract: Existing schemes have been firstly analyzed for secure routing protocol in Ad hoc networks. Then we present a new scheme for secure routing protocol base on AODV. Security features in the routing protocol include threshold authentication mechanism based on elliptic curve cryptosystem algorithm and improved the process of authentication without relying on the availability of a certificate authority center. Furthermore, the neighbor supervising mechanism combining with reputation mechanism are adopted to strengthen the management and supervision to network nodes, make the whole process of routing protocol under administration and supervision.

Abstract: 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.

Abstract: DATA flooding attack is a serious menace for the security of on-demand routing protocol in Ad Hoc networks. In the paper, on the basis of three typical on-demand routing protocols AODV, DSR and TORA, we present a special security scheme against data flooding attack. Then we simulate the scheme on NS2 platform and compare two performance parameters before and after using the scheme: average delay and packet delivery rate. The results indicate that this project is comparatively effective to resist the DATA flooding attack.
