Improved Key Distribution and Management in Wireless Sensor Network
Journal of Wireless Communications, 2016 Key set up and distribution in sensor network is a complex task due to inherent limitations in sensor networks. For reducing the “communication and computation overhead” we proposed that the sensor network is partitioned into different zones. Each zone has a separate intrusion detection system (IDS) and key distribution center (KDC).IDS can detect the ...

International Journal of Distributed Sensor Networks, 2015 Security in wireless sensor networks (WSNs) demands efficient key management schemes. In particular, one of the main research challenges is to ensure secure key storage by sensors due to their constrained resources and high exposure to tampering attempts.

OVERVIEW ON KEY DISTRIBUTION PRIMITIVES IN WIRELESS SENSOR NETWORK [PDF]
Journal of Computer Science, 2013 Owing to the security requirements of wireless sensor network, the background of Wireless Sensor Network (WSN) is to be analyzed with different threats and attack models. Physical compromising of sensor nodes by an adversary is an emerging problem in sensor network and accordingly, it is necessary to provide an environment with efficient key management

The Study on Key Pre-distribution Methods for Wireless Sensor Networks
Physics Procedia, 2012 AbstractInspired from the key distribution scheme of Du's rectangle scheme, we propose a new hexagon scheme. With the same grid number t and n, the same farthest distance between two neighbor grids R, the new scheme's coverage is 0.5988 larger, and the Pl is higher than Du's method.

A Flexible and Efficient Key Distribution Scheme for Renewable Wireless Sensor Networks [PDF]
EURASIP Journal on Wireless Communications and Networking, 2009 Many applications of wireless sensor network require secure data communications, especially in a hostile environment. In order to protect the sensitive data and the sensor readings, secret keys should be used to encrypt the exchanged messages between communicating nodes.

A Key Distribution Scheme for Mobile Wireless Sensor Networks: $q$ - $s$ -Composite
IEEE Transactions on Information Forensics and Security, 2017 The majority of security systems for wireless sensor networks are based on symmetric encryption. The main open issue for these approaches concerns the establishment of symmetric keys. A promising key distribution technique is the random predistribution of secret keys.
