Security issues have been emphasized when mobile ad hoc networks (MANETs) are employed into military and aerospace fields. In adversary environments, Anonymous communications are important for many a pplications of the mobile ad hoc networks (MANETs) deployed. A requirement on the network is to provide unidentifiability and unlinkability for mobile nodes and their traffics. Eventhough a number of anonymous secure routing protocols have been proposed, the requirement is not fully satisfied. A new routing protocol, i.e., authenticated anonymous secure routing (AASR), to satisfy the requirement and defend the attacks is being proposed in this paper. The key-encrypted onion routing with a route secret verification message, is designed to prevent intermediate nodes from inferring a real destination. Simulation results have demonstrated that the proposed Novel protocol is effective with improved performance when compared with the existing protocols. The salient feature of AASR is that when trust relationships in such among nodes, there is no need for a node to request and verify certificates every time which reduces the computation overheads. Meanwhile, with neighbors' trust recommendations, a node can make objective judgement about another node's trust-worthiness to maintain the whole system at a certain security level.
