To solve radically the contradiction between the severely limited resource and security for the application in privacy-vital environment in wireless sensor networks (WSNs), we propose a new routing protocol called ITSRP: an Intrusion-tolerant secure routing protocol. We securely and efficiently reconstruct the routing packet in which we design some fields to emphasize the security accounting to the key exchange, but the design doesn't result in the complexity of the protocol. In comparison with other previous secure routing protocols, ITSRP integrates the authenticated key exchange and energy factor into the secure routing algorithm and tolerates damage caused by salient intruders who has compromised deployed sensor nodes and is intent on injecting, modifying or blocking packets. The security mechanism incorporated defends against wormhole attacks, sinkhole attacks and sybil attacks etc. Simulation results and comparisons with existing protocols prove the advantages and the effectiveness of ITSRP.
