随着无线传感器网络应用的日益广泛，对于军事、商业和家庭环境，保护网络中的数据已经成为一个关键问题。已经引入了几种安全机制，如TinySec，以解决无线传感器网络中的安全需求。然而，安全成本仍然是一个未知的变量。为了更好地理解这种成本，我们研究了无线传感器网络安全加密的三个方面算法分组密码和消息认证算法的工作模式我们在MicaZ和TelosB传感器微粒上测量和比较了它们的存储器和能量消耗我们的实验结果提供了对不同安全算法在无线传感器网络环境中的适用性的深入了解，并且可以被无线传感器网络设计者用来构建他们的系统的安全体系结构，以满足应用的要求，合理使用有限的传感器资源（C）2010 Elsevier BV版权所有
With the increased application of wireless sensor networks (WSNs) to military commercial and home environments securing the data in the network has become a critical issue Several security mechanisms such as TinySec have been introduced to address the need for ecurity in WSNs The cost of security however still mostly remains an unknown variable To provide a better understanding of this cost we have studied three aspects of WSNs security encryption algorithms modes of operation for block ciphers and message authentication algorithms We have measured and compared their memory and energy conumption on both MicaZ and TelosB sensor motes The results of our experiments provide insight into the suitability of different security algorithms for use in WSN environments and could be used by WSN designers to construct the security architecture of their systems in a way that both satisfies the requirements of the application and reasonably uses the constrained sensor resources (C) 2010 Elsevier BV All rights reserved
