HPCT:A Novel Scheme for Protecting Source-Location Privacy in WSN

Abstract

In wireless sensor networks (WSNs), although there are many existed schemes for the local eavesdropper. However, a global eavesdropper who is well-equipped, highly motivated and has the ability to compromise node can make those method invalid, so that those existing techniques can't be against such attacks. In this paper, we proposed the Hash Periodic Collection technology (HPCT) through applying the hash encryption to the PCT for the purpose of protecting the location privacy of the source node under the global eavesdropping attacks and compromised node attacks. The experiment showed that the Hash Periodic Collection technology (HPCT) we introduced is better than PCT, and the HPCT dramatically increased the security and safety time of the source location privacy.
