Abstract

Wireless sensor networks (WSNs) are considered to be an ideal solution for many commercial and industrial applications due to their low-cost and easy deployability. However, Security is a critical concern in WSNs due to the technical challenge of providing sufficient security with battery-powered sensors that have limited computational resources. Although numerous advancements have been made in the field of key management in WSNs, most have focused on establishing keys within a single WSN. In addition, many have assumed that the locations of the sensors are fixed. As the number of WSN applications increases, there is an increasing demand for solutions that allow sensors to securely roam between different WSNs even when the WSNs are managed by independent organizations. This paper presents a base station-to-sensor pairwise key management protocol that allows sensor nodes to relocate to other WSNs as required by the application. In addition, the proposed solution localizes the damage that can arise when a sensor or a base-station is compromised without increasing the computational burden on the sensors. To the best of our knowledge, this is one of the first few works to address the pairwise key distribution problem in WSNs that allow nodes to roam between different, independent networks.
网络间传感器漫游无线传感器网络中的密钥管理
无线传感器网络(wsn)由于其低成本和易于部署而被认为是许多商业和工业应用的理想解决方案。然而,在无线传感器网络中,安全性是一个关键问题,因为在计算资源有限的电池供电传感器中提供足够的安全性是一项技术挑战。虽然在无线传感器网络的密钥管理领域已经取得了许多进展,但大多数都集中在单个无线传感器网络内建立密钥。此外,许多人认为传感器的位置是固定的。随着WSN应用数量的增加,对允许传感器在不同WSN之间安全地漫游的解决方案的需求越来越大,即使这些WSN是由独立组织管理的。本文提出了一种基站到传感器的成对密钥管理协议,该协议允许传感器节点根据应用需要重新定位到其他wsn。此外,所提出的解决方案在不增加传感器计算负担的情况下,将传感器或基站受到损害时可能出现的损害定位。据我们所知,这是解决wsn中允许节点在不同的独立网络之间漫游的成对密钥分配问题的为数不多的工作之一。
