A Hybrid Key Pre-Distribution Scheme for Securing Communications in Wireless Sensor Networks
Wireless Sensor Network (WSN) is a type of ad hoc networks which consist of hundreds to thousands of sensor nodes. These sensor nodes collaborate to surveillance environment.

A survey of key distribution in wireless sensor networks [PDF]
AbstractKey establishment is the most fundamental cryptographic primitive in all kinds of applications where security is a concern. However, the nature of limited resources on sensor nodes restricts the use of conventional key management techniques in wireless sensor networks.

Grouping Sensors for the Key Distribution of Implicit Certificates in Wireless Sensor Networks
As sensor nodes communicate via wireless channels, information security is essential for wireless sensor networks. Efficient protection mechanisms to ensure data security among nodes are critical. This study developed the bi-directed grouping (top-down grouping (TDG) and bottom-up grouping (BUG)) methods.

One of the challenges in securing wireless sensor networks (WSNs) is the key distribution; that is, a single shared key must first be known to a pair of communicating nodes before they can proceed with the secure encryption and decryption of the data. In

Low-Energy Symmetric Key Distribution in Wireless Sensor Networks [PDF]
In this work, a scheme for key distribution and network access in a Wireless Sensor Network (WSN) that utilizes Identity-Based Cryptography (IBC) is presented. The scheme is analyzed on the ARM920T processor and measurements were taken for the runtime and energy of its components.

Improved Key Distribution and Management in Wireless Sensor Network
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 ...

OVERVIEW ON KEY DISTRIBUTION PRIMITIVES IN WIRELESS SENSOR NETWORK [PDF]
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
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.
