摘　　要：为了增加对称密钥被破解的难度,提出一种基于混淆的密钥管理机制,来增加信息传输的安全性。在管理机制中应用一种混淆的多重加密方法,此方法是以时间参数组成的时间集为随机参数与混淆理论结合对信息进行加密;通过连通性分析、节点能耗和抗攻击能力对这种管理机制进行了分析,论证了其实用性。In order to increase the symmetric key＇ s security,a confusion-based symmetric key management mechanism was proposed to enhance the security of transmitting information.A confusion-based multiple encryption method in the management mechanism takes the time set composed by time parameters as the random parameter and then has it combined with the confusion theory to encrypt the information; analyzing the connectivity,the node energy and the ability against attacks proves the practicability of this management mechanism.
