A Novel Message Signature Scheme for Sparse Mobile Ad Hoc Network
Bin Liu · Information Security and Communications Privacy · 2011
Aiming at the delay/disruption feature of sparse mobile Ad Hoc network,this paper proposes a novel message signature scheme based on IBC(Identity–Based Cryptography) and ECBP(Elliptic Curve Bilinear Pairings). The security and performance of scheme is also analyzed. This scheme can solve the key escrow problem,limit the invalid message caused by the compromised private keys spreading in the network. On the premise of ensuring security,effective reduction of the key length,signature length and computation,and thus the network communication bandwidth and node memory and computation makes this scheme more suitable for sparse mobile Ad Hoc network.
