Abstract: A new secure and anonymous routing protocol based on trust valuation for mobile Ad-Hoc networks was presented.It introduces a system of trust valuation that could dynamic and in time discover malicious actions in networks and makes nodes free of overweight security processing.As a result,the low complexities of routing protocol can be achieved.Before established routing,there is completed the bidirectional anonymous authentication between CA and communication node.An anonymous identity of nodes presented by the hash routing was stored in routing table,it can effectively ensure the anonymous of the networks and avoid launching a routing request repeatedly so it improves the efficiencies.Based on the Diffie-Hellman key agreement arithmetic,the protocol set up the key agreement.The protocol combines with symmetric cryptographic algorithm and asymmetric cryptographic algorithm,it makes the structure of the protocol simple and availability.
