Study of Security Base on Wireless Sensor Network Routing Protocol

In the course of data transfer extremely vulnerable to be eavesdropped, defrauds, tampered or replayed (relay) routing by information security. Thus, the SLDMRP (security lightweight distribution multicast routing protocol) based on security was put forward in this paper. This protocol is designed on the basis of the multicast routing LDMRP, while this protocol creating and maintaining multicast group, sending control message, carrying out security policy which underwrite and verify the data packets, in order to prevent the control message from eavesdropping and tampering. Finally, using NS2, to prove the effectiveness of signature and verify. The simulation results: SLDMRP, which is using of SHA-1 and RSA encryption algorithm to verify the signature and security policy is effective.
