Security Analysis and Improvement of Secure and Dynamic Clustering Protocol

In this paper, we analyze a secure and dynamic clustering protocol SecDEACH. Through analysis, we show that the protocol is vulnerable to the wormhole attack since it does not consider the verification of the neighbor nodes within its radio range. We give a wormhole attack to the protocol and propose an improved version which can keep the frame of the SecDEACH protocol and overcome the security shortages. Finally, we make an analysis of the improved protocol and conclude the paper.
