Bilinear Map Key Management Scheme with Dishonest Behavior Discovery

In large-scale mobile Ad-Hoc network,there exists problem of nodes′ dishonest behaviors.Due to this,we designed a novel key management scheme with dishonest behavior discovery mechanism.The proposed scheme is based on techniques of combined public key and threshold secret sharing,and uses bilinear map algorithm to design the verification mechanism of secret shares.Comparisons with existing schemes show that the proposed scheme not only ensures good efficiency,security and scalability,but has strong robustness against dishonest nodes.The proposed scheme can suit large-scale mobile Ad-Hoc network well.
