Abstract: Concerning the masquerader attacks in the sensor network, a new masquerader detection scheme was proposed. By means of the identity-based signature technique and node alarming rules, a single masquerader detection algorithm was constructed, which was based on the neighbor mutual authentication. Moreover, an algorithm to detect multiple masqueraders was acquired from this. In addition, the succeeded masquerader detection algorithm was proposed in this scheme in which the sink nodes monitor and examine the malicious region, and the normal nodes identify and transmit the alert messages. The proposal scheme is applicable to complicated masquerade attack and high network security demanding environment. The simulation experiments show the effectiveness in detection of the proposed scheme.
