An efficient symmetric polynomial-based key establishment protocol for wireless sensor networks

Authors

Abstract:

An essential requirement for providing secure services in wireless sensor networks is the ability to establish pairwise keys among sensors. Due to resource constraints on the sensors, the key establishment scheme should not create significant overhead. To date, several key establishment schemes have been proposed. Some of these have appropriate connectivity and resistance against key exposure, but the resources needed in the sensors are substantial. Others are appropriate from the resource consumption perspective, but have weak performance. This paper proposes a key establishment protocol based on symmetric polynomials. To improve performance, the protocol uses a new model to distribute polynomial shares to the sensors. A key feature of the proposed protocol is the trade-off between performance, security and resource consumption. Analysis shows that our solution has good performance compared to other approaches.

EEQR: An Energy Efficient Query-Based Routing Protocol for Wireless Sensor Networks

Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...

Toward an energy efficient PKC-based key management system for wireless sensor networks

Due to wireless nature and hostile environment, providing of security is a critical and vital task in wireless sensor networks (WSNs). It is known that key management is an integral part of a secure network. Unfortunately, in most of the previous methods, security is compromised in favor of reducing energy consumption. Consequently, they lack perfect resilience and are not fit for applications ...

Key Establishment Protocol for Wireless Sensor Networks

Wireless sensor networks usually comprise a number of sensors with limited resources. Each sensor includes sensing equipment, a data processing unit, a short range radio device and a battery [Pottie & Kaiser, 2000; Kahn et al.,1999; Akyildiz, 2002]. These networks have been considered for various purposes including border security, military target tracking and scientific research in dangerous e...
