The challenging nature of insecure wireless channels and constrained resources make protection for wireless sensor networks (WSNs) an especially essential problem. The existing work has focused on preventive techniques to achieve location privacy protection, while the location privacy risk assessment receives less attention. In this paper, we propose a novel risk assessment approach to evaluate the...
Key management is at the heart of securing wireless sensor networks. Exclusion Basis Systems (EBS) is a combinatorial framework for group key management. It is secure and efficient for dynamic key management; however it could not resist collusion attack. A novel scheme combining EBS with broadcasting polynomial, LEP was proposed to solve this problem. Compromised nodes can be evicted by rekeying....
