Key management is a corner stone service for any security solution for WSNs. Resources limitation of WSNs makes the public key based solutions, which offer more efficient key management services, unsuitable for wireless sensor networks. In this paper, we propose a novel efficient tree-based probabilistic key management scheme which is highly resilient against node capture attacks. Our solution is...
Traditional key management techniques, such as public key cryptography or key distribution center (e.g., Kerberos), are often not effective for wireless sensor networks for the serious limitations in terms of computational power, energy supply, network bandwidth and defection of centra authority. In order to balance the security and efficiency, we propose a new scheme by employing LU Composition techniques...
Wireless sensor nodes have restricted computational resources, and are always deployed in a harsh, unattended or hostile environment. Therefore, network security represents a challenging task. This work presents a public-key based pre-distribution scheme with time-position nodes for simultaneous exchange of secure keys. The proposed defend attack and key management mechanism for sensor network applications...
