One Hop Key Management Scheme for Wireless Sensor Network Using Deployment Knowledge
نویسندگان
چکیده
In this paper we propose a light-weight random key pre-distributed scheme based on deployment knowledge. It uses only one hop for key distribution. It leads to a substantial reduction in energy requirement while improving key sharing and resilience factor compared to the scheme proposed in [1]. We develop the theoretical background of the proposed scheme and explain why the proposed scheme performs better than [1]. In addition, we simulated both schemes over TOSSIM to establish that proposed scheme substantially improves key sharing over [1] in practice.

LPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring
Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
متن کاملHybrid Key pre-distribution scheme for wireless sensor network based on combinatorial design
Key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.Due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. To establish a secure communication, two nodes must share common key from their key-rings. Otherwise, they can find a key- path in which ens...
