A PKC-Based Node Revocation Scheme in Wireless Sensor Networks

Abstract

[[abstract]]Generally deployed in an unattended environment, a sensor network can be easily assaulted or compromised by adversaries. Network security becomes a major problem. A distributed node revocation scheme is effective in reducing the damages a compromised node may cause to a sensor network, but its operation tends to consume large-scale memory space of the hardware-constrained sensor nodes. To reduce such complexity, this paper presents a new distributed voting revocation scheme based on the one-way hash chain, the concept of threshold secret sharing, the certificate revocation list and the public-key cryptography.[[conferencetype]]國際[[conferencedate]]20071206~20071208[[iscallforpapers]]Y[[conferencelocation]]Jeju, Kore
