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).

Novel key pre-distribution scheme in wireless sensor network

2011 International Conference on Emerging Trends in Electrical and Computer Technology, 2011
Wireless sensor networks (WSN) usually consists of a large number of tiny sensors with limited computation capability, memory space and power resource. Many key pre-distribution techniques have been developed recently to establish pair wise keys between sensor nodes in WSN. Sensors are usually deployed for sensing data in the field.

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.

Key Distribution in Wireless Sensor Networks Using Finite Affine Plane

2011 IEEE Workshops of International Conference on Advanced Information Networking and Applications, 2011
Key management is an important area of research in Wireless Sensor Networks (WSN), because resource constraints make security protocols difficult to be implemented. Key predistribution, which involves preloading keys in sensor nodes, has been considered as the best solution when sensor nodes are battery powered and have to work unattended. We propose a

A mutual-healing key distribution scheme in wireless sensor networks

Journal of Network and Computer Applications, 2011
How to establish secure session keys is one of the central tasks for wireless sensor network communications. General key distribution schemes for traditional computer networks could not be directly shifted to wireless sensor network environments as broadcast messages may be lost due to sensor network internal factors or external attacks.

A Novel Key Distribution Algorithm in Wireless Sensor Network

2014 Sixth International Conference on Measuring Technology and Mechatronics Automation, 2014
This paper studies the E-G key pre-distribution algorithm principle, and a new key distribution algorithm based on the Blom key pre-distribution model is proposed. The nodes is deployed in a hexagonal area. Each cluster uses preshared key to establish key pair, Blom key pre-distribution model is used in the establishment of key pair among clusters. The

Secure Secret Key Distribution and Storage in Wireless Sensor Networks

2010 10th IEEE International Conference on Computer and Information Technology, 2010
Security in Wireless Sensor Networks (WSNs) is commonly bootstrapped by cryptographic key distribution among nodes. In this scenario, one of the greatest research challenges is to ensure secure keys storage by sensors due to their constrained resources and major exposure to tampering attempts.

A Novel Key Pre-distribution Scheme in Wireless Sensor Networks

2014 Tenth International Conference on Computational Intelligence and Security, 2014
Key management for wireless sensor networks has been a challenging research topic since stringent resource constraints make the key pre-distribution schemes difficult to implement. This paper proposes a novel key pre-distribution method based on trivariate symmetry polynomial and hash function.

Expander Graph based Key Distribution Mechanisms in Wireless Sensor Networks

2006 IEEE International Conference on Communications, 2006
Secure communications between large number of sensor nodes that are randomly scattered over a hostile territory, necessitate efficient key distribution schemes. However, due to limited resources at sensor nodes such schemes cannot be based on post deployment computations.

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
