Data security in MANETs by integrating multipath routing and secret sharing

Secure routing protocol attracts much more attention in mobile ad hoc networks for the purposes of secure data transmission. But the improvement of security often sacrifices the delivery rate or other QoS. We propose a secure routing protocol by integrating multipath routing and secret sharing, meanwhile, select efficient and secure multiple disjoint routes by integrating multiple metrics including hop count, traffic load, node compromising and broken probability as an effective mechanism to protect data security and simultaneously enhance performance efficiency in the whole transmission process. In addition, we also introduce hash function to detect active attacks in our data transmission process. Simulation results show that our scheme provides a reasonably good level of security and performance efficiency.
