Abstract: The existing key management scheme applied to wireless sensor network hardly considers the phenomena that unreliability of wireless links and the packet loss rate in the network. In this paper an anti-compromise and energy effective authentication encryption algorithm（STAE） is presented, using the methods of sub-transmission, OFB block cipher, authentication and reconstruct the information, the safety and efficiency of the data transfer and reconstruction are enhanced, and it ensures that the network can effectively resist the behaviour such as listening, data tampering, and DoS attacks while there are certain packet loss rate and part of the compromise node in the network. The simulation results show that the STAE algorithm has a large advantage about the security communication and the network energy consumption.

摘要： 现有的应用于无线传感网的密钥管理方案，几乎没有考虑无线链路的不可靠性，网络中存在丢包率这一现实。提出一种能量有效的抗妥协的认证加密算法STAE，采用分段传输、OFB分组加密、认证并重构信息等方法，增强了数据传输和重构的安全性及效率，保证网络中存在一定丢包率和部分妥协节点的情况下，仍能有效地抵御侦听、数据篡改和DoS攻击等行为。仿真结果表明STAE算法在安全通信和节省网络能耗方面具有较大的优势。
