A secure elliptic curve communication scheme for the cluster-based ad hoc networks

Near Term Digital Radio (NTDR) networks, which follow the cluster based design principles, are developed specifically to use in ad hoc settings. A major challenge in the design of these networks is their vulnerability to security attacks, due to unreliable wireless media, host mobility and lack of infrastructure. In this paper, we propose an elliptic curve secure communication scheme for NTDR networks. Specially, an authentication mechanism for a mobile node joining into cluster is introduced. Additionally, End-to-end secure communication and group secure communication in NTDR networks are also described. The security of our proposed scheme is guaranteed by the conjecture that solving the Elliptic Curve Computational Diffie-Hellman Problem (ECCDHP) is intractable.
