SMART: Secure Multi-pAths Routing for wireless sensor neTworks

Abstract

Abstract. In this paper, we propose a novel secure routing protocol named Secure two-hop disjoint Multi-pAths Routing for wireless sensor neTworks (SMART) as well as its underlying key management scheme named Extended Two-hop Keys Establishment (ETKE). The proposed framework keeps consistent routing topology by protecting the hop count information from being forged. The two-hop scheme ensures immediate verification and fast detection of inconsistent routing information with- out referring to the sink node. We prove that it is sufficient to keep only two-hop disjoint paths to ensure full-resilience against node capture attacks. We have demonstrated through simulations that our solution outperforms a comparative solution in literature. In addition, ETKE is more resilient to node capture attacks than the probabilistic key man- agement schemes.
