摘　　要：无线传感器网络节点受到能耗和物理尺寸的限制,选择占用存储少和节能高效的分组加密算法对无线传感器网络非常重要。针对多种分组加密算法,构建评测系统框架,于不同的应用环境和网络结构中,对算法安全性能、存储量和能效指标进行评测。分析评测结果表明:Rijndael加密算法的高安全性、高能效使其最为适合无线传感器网络。The notes in Wireless Sensor Networks（WSNs） are high limited due to its small physical size. Therefore choosing the most storage- and energy-efficient block cipher for WSNs is important. In this paper, the block ciphers suitable for WSNs are identified based on security, storage and energy cost in different applications. These candidates are benchmarked and based on this benchmark, the suitable ciphers for WSNs are selected, namely Rijndael for high security and energy efficiency requirements, and MISTY1 for good storage and energy efficiency. In terms of operation mode, Output Feedback Mode is recommended for static networks, but Counter Mode for dynamic networks.
