Using Trust in Key Distribution in Wireless Sensor Networks

2007 IEEE Globecom Workshops, 2007
This paper presents a new approach of dynamic symmetric key distribution for encrypting the communication between two nodes in a wireless sensor network (WSN). The distribution of a shared key can be performed by any sensor node and does not always require that it is performed by the base station (BS).

Initial Key Distribution for Industrial Wireless Sensor Networks

2013 IEEE International Conference on Industrial Technology (ICIT), 2013
In any security design, the initial secret distribution for further key management solution is a major step. In industrial wireless sensor networks also, initial bootstrapping of the trust in the system is a major concern. The plant can be assumed to be a closed system, where only authenticated and trusted users are allowed to enter.

Deterministic schemes for key distribution in wireless sensor networks

2008 3rd International Conference on Communication Systems Software and Middleware and Workshops (COMSWARE '08), 2008
In this paper, we propose a new security metric for measuring resilience of a symmetric key distribution scheme in wireless sensor network. A polynomial-based and a novel complete connectivity schemes are proposed and an analytical comparison, in terms of security and connectivity, between the schemes is shown.

A Combinatorial Approach for Key-Distribution in Wireless Sensor Networks

IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008
Sensor nodes are usually deployed in adversarial environments in which they are subject to compromise and revelation of critical information rendering the entire network useless. Therefore, secure communication of wireless sensor networks (WSNs) necessitates utilization of efficient key distribution schemes. Over the past few years, several works using

A lightweight key distribution mechanism for wireless sensor networks

SPIE Proceedings, 2008
Security is of critical importance for many potential applications of wireless sensor networks. In order to maintain secure communication throughout the network, it is of vital importance to maintain encryption key freshness by regularly distributing new keys to all nodes.

Study on key distribution scheme for wireless sensor networks

2010 2nd International Conference on Computer Engineering and Technology, 2010
For solving the issue of key distribution in the clustered sensor networks, proposed a key distribution scheme based on layers, in which base station sends the secret knowledge of member nodes to the cluster-header, and member nodes establish pairwise key with their neighbor nodes via cluster-header.

A Distributed Key Management Protocol for Wireless Sensor Network

2018
In sensor network where large group of nodes share the information, in such scenario it’s difficult to scale the application, in addition security in wireless sensor network often vary with purpose and context, but in broad-spectrum, security for wireless sensor networks should centered on the protection of the data itself and the network ...

Distributed Energy Efficient Key Distribution for Dense Wireless Sensor Networks

2009 First International Conference on Computational Intelligence, Communication Systems and Networks, 2009
The recent research in Wireless Sensor Networks has led to a number of security schemes. The main requirement in Wireless Sensor Networks is not only security but energy efficient security due to limited resources. We propose an energy efficient key management protocol fully developed in TinyOS and tested in Avrora Emulator.

A novel key pre-distribution scheme for wireless distributed sensor networks

Science China Information Sciences, 2010
A novel key pre-distribution scheme for sensor networks is proposed, which enables sensor nodes to communicate securely with each other using cryptographic techniques. The approach uses the rational normal curves in the projective space with the dimension n over the finite field \( \mathbb{F}_q \).
