The node replica attack is known to be dangerous to wireless sensor networks (WSNs) because it enables the adversary to extend the damage throughout the network with very low cost. To stop such attack, we propose a similarity estimation based scheme with group deployment knowledge. Compared with prior works, our proposal provides extra functionality that prevent replica from generating false location...
To minimize the damage of false data injection attack, detecting the false injected data for the in-network aggregation in sensor networks at an early stage becomes a necessary and challenging task. In this paper, we adopt Hierarchical Bayesian Space-Time (HBST) methodology to characterize the data model of in-network aggregation, and propose a divided difference filter (DDF) based scheme LFDD to...
In this paper, we propose a novel authenticated key agreement scheme using Pairing-based Cryptography, named IBAKA, to address the problems of high memory occupation, low key connectivity and poor resiliency against node capture attacks existed in the traditional key management protocols of large scale sensor networks. Our proposal, which works based on the elliptic curve Diffie-Hellman (ECDH) exchange...
