由于传感器资源的限制，在传感器网络中建立密钥是一个具有挑战性的问题。由于资源的限制和传感器节点容易被物理捕获，传统的公钥例程在大多数传感器网络体系结构中是不切实际的。本文提出了一种新的随机密钥预分发方案。我们的方案总是定义邻居节点的id和这些节点拥有的密钥之间的关系，同时保持密钥选择所需的随机性。我们提出的方案比现有的随机密钥预分发方案具有更好的抗节点捕获攻击的安全性。此外，与现有的随机密钥预分发方案相比，它在通信开销、网络连接性和防止节点捕获的安全性之间有更好的权衡。此外，它还支持在网络中节点初始部署后，高效地动态添加节点。版权所有©2009 John Wiley & Sons， Ltd
Key establishment in sensor networks is a challenging problem because of resource constraints of the sensors. Due to resource limitations and vulnerable to physical capture of the sensor nodes, the classical public-key routines are impractical in most sensor network architectures. In this paper, we propose a new random key pre-distribution scheme. Our scheme always defines a relationship between the ids of neighbor nodes and the keys possessed by those nodes while maintaining the required randomness in choice of keys. Our proposed scheme provides better security against node capture attack than the existing random key pre-distribution schemes. Moreover, it has better trade-off between communication overhead, network connectivity and security against node capture compared to the existing random key pre-distribution schemes. In addition, it supports dynamic node addition efficiently after initial deployment of the nodes in the network. Copyright © 2009 John Wiley & Sons, Ltd.
