Abstract: Key distribution is one of the fundamental building blocks of security services for sensor networks.As sensor networks are very resource-constrained and of large scale,traditional key distribution techniques,such as public key cryptography or key distribution center,are often not effective.A secure and efficient key distribution scheme for wireless sensor networks is presented in this paper.This scheme is based on secure two-party computation.Then the performance of the scheme in term of memory usage,communication and computational overhead and security is analyzed.Compared with other schemes,this one has better performances,which needs less computing overhead and can enhance the security,so it is very suitable for wireless sensor networks.

摘要: 密钥分配对于无线传感器网络(WSN)的安全起着基础性作用。由于传感器网络规模大、节点资源非常受限等特点,传统的基于公钥和可信任密钥分配中心等方式不能使用。提出了一种新的WSN密钥分配方案,并对其存储量、通信量、计算量和安全性进行了分析。该方案基于安全两方计算,计算负载小,安全性高,适合传感器网络。
