In order to improve the security of TEEN routing protocol in wireless sensor networks, a hybrid encryp-tion algorithm applied to TEEN protocol is proposed: a symmetric encryption for the intracluster and a public key encryptionfor the intercluster.The simulation results show that the TEEN protocol based on hybrid encryption algo-rithm is safer than the TEEN protocol only based on symmetric encryption algorithm in information transmission suc-cess rate,and can resist against attacks and prevent tampering routing information.%针对TEEN路由协议在无线传感器网络(WSNs)中存在的安全性问题,提出了一种应用于TEEN协议的混合型加密算法.簇内使用对称加密,簇间使用公钥加密.仿真结果表明,使用了混合型加密算法的TEEN协议与只使用了对称加密算法的TEEN协议相比能够提供更高的传输成功率,并且能够抵御女巫攻击和防止篡改路由信息.
