A new ADV-hash approach supporting secure and DoS-resistant network reprogramming in wireless sensor networks(WSNs)

Aim: Existing secure network reprogramming protocols are, in our opinion, deficient in that attackers can exploit the Deluge epidemic and suppression mechanism to launch denial of service (DoS) attacks. We propose a new ADV-Hash approach which we believe is without this deficiency. Section 1 of the full paper classifies the DoS attacks - caused by bogus advertisements - into three types. The core idea of section 2 consists of: (1) the ADV-Hash approach maps all the advertisements of coded updates onto a limited sequence of messages; (2) it employs the public key cryptography to sign the root of an ADV-Hash chain for once only so that the nodes of WSNs can achieve the lightweight authentication of control message. The TOSSIM simulation results, given in Figs. 5 through 7, and their analysis show preliminarily that our new ADV-Hash approach can effectively avoid the attacks caused by bogus advertisements without affecting the epidemic nature of the Deluge protocol, thus providing network reprogramming protocols with service availability.
