摘　　要：近年来,物联网感知层的核心组成部分无线传感器网络,在军事、环保、医疗等诸多领域的应用越来越广泛,其安全性问题日益突出,需要采用认证加密手段应对。给出一种基于标识密码机制的无线传感器网络认证加密方法:首先在物联网应用层部署IBC密钥基础设施;然后,IBC密钥基础设施为传感器签发IBC私钥;最后,传感器之间通过IBC密钥加密对称密钥实现加密密钥分发,实现业务数据加密传输。该方法在实际应用中可以基于SM9算法实施部署。In recent years,the wireless sensor network,the core component of the perception layer of the Internet of things,has been applied more and more widely used in many fields such as the military,environmental protection,and medical and other fields,and its security problems are increasingly prominent,which requires the use of authentication and encryption means to deal with.This paper presents an authentication encryption method based on identity-based cryptography in the wireless sensor network.Firstly,IBC key infrastructure is deployed in the application layer of the Internet of things.The IBC key infrastructure then signs the IBC private key for the sensor.Finally,the symmetric key is encrypted by IBC key among the sensors to realize the encryption key distribution and the business data encryption transmission.The Internet of things authentication encryption mechanism presented in this paper can be deployed based on SM9 algorithm in practical applications.
