Abstract: Lots of anonymous protocols for Ad Hoc network have been proposed to enforce the anonymity of the nodes in the network. However, most of the protocols utilize many asymmetric key computations which consume vast time and resources, thus, these protocols are not so suitable for those nodes in Ad Hoc network with limited power and poor computational ability. Hence, a new lightweight protocol with anonymity for Ad Hoc network was proposed. The new protocol ensured many security features and anonymity; most importantly, it employed bilinear pairings to realize the authenticated key exchange. Compared with other protocols, the proposed protocol is more efficient in routing construction by lowering the computing time to large extent and reducing the asymmetric key computation.
