An Improved Identity-Based Secure Mobile Ad-Hoc Network Routing Protocol

Mobile ad-hoc networks have important applications in many fields, such as battlefield environment, temporary meeting, field detection and even underground mine. The OLSR protocol is an important mobile ad-hoc network routing protocol that has become an international standard, but the initial design of the protocol lacks security considerations. Aiming at the security routing problem of OLSR protocol, some security enhancement methods have been proposed, but there are still some shortcomings in the confidentiality of message transmission and encryption efficiency. After analyzed the OLSR protocol, we proposes a security OLSR protocol based on identity-based signcryption, which uses identity-based signcryption to sign packets, so we can achieve authentication and protective the original packets been tampered. The scheme is more efficient and more secure than the existing enhancement scheme, and can guarantee the safe operation of the OLSR protocol.
