An Anti-Clone Attack Key Management Scheme for Wireless Sensor Networks

摘要

Wireless Sensor Networks (WSNs) are subject to various kinds of attacks such as replaying ofmessages, battery exhausting, and nodes compromising. While most of these attacks can bedealt with through cryptographic security protocols provided by key management schemes,there are always a few that manage to really cause problems. One such attack that is mostcommon and significant in WSNs is cloning attack. In clone attack, the intruder tries to captureand compromise some nodes and inject them into several locations throughout the network inorder to conduct other types of attacks. Moreover, if this attack is not detected early, then thesereplicated injected nodes will consume a large amount of the network resources. In this paper,we analyze several key management schemes that can be used for checking integrity andpreventing cloning attacks. After analyzing the problems associated with these schemes, wepropose a model that allows us to distinguish between legitimate nodes and cloned nodes insuch sensor networks.
