Hybrid 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...
متن کاملProvably Secure Key-Updating Schemes in Identity-Based Systems
In this pa.per, we present Key-Updating Schemes in identity-based (identification or signature) systems, and consider the security of the schemes. We ’ propose two kinds of key-updating schemes, i.e., one is sequential type and the other is parallel type, and show that both schemes are equivalent to each other in a polynomial time sense, i.e., there elrists a deterministic polynomial time algor...

متن کاملHypercube Bivariate-Based Key Management for Wireless Sensor Networks
Wireless sensor networks are composed of very small devices, called sensor nodes,for numerous applications in the environment. In adversarial environments, the securitybecomes a crucial issue in wireless sensor networks (WSNs). There are various securityservices in WSNs such as key management, authentication, and pairwise keyestablishment. Due to some limitations on sensor nodes, the previous k...
متن کاملSelecting key management schemes for WSN applications
Key management in wireless sensor networks (WSN) is an active research topic. Due to the large number of key management schemes (KMS) proposed in the literature, it is not easy for a sensor network designer to know exactly which KMS best fits in a particular WSN application. In this article, we offer a comprehensive review on how the application requirements and the properties of various key ma...
