针对现有物联网传输机制的安全问题，提出一种基于认证的安全传输机制。在物品信息的感知阶段给出基于认证的RFID协议以保证标签的正确性，通过Hash计算、嵌套加密等操作，实现本地物品信息服务器与远程物品信息服务器间物品信息的安全传输。基于物联网的温湿度传感器实验与无陑通信实验结果表明，该机制能够保证信息的安全传输，计算开销和通信开销均优于MLDL方法。%For the disadvantages of existing transmission mechanisms, this paper proposes a securely transmission mechanism based on certification. A RFID protocol is presented to ensure the correctness of the label in the perception stage, and the securely transmission between the Local Information Server of Things(LIST) and the Remote Information Server of Things(RIST) is accomplished by the Hash calculation and nested encryption operation. Results of temperature and humidity sensor experiment and wireless communications experiment based on the Internet of Things(IoT) show that this method is effective, can ensure the security of information transmission, and its computational overhead and communicational overhead are also lower than the existing MLDL methods.
