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. Key wordsInternet of Things(IoT); transmission mechanism; certification; Local Information Server of Things(LIST); Remote Information Server of Things(RIST) DOI: 10.3969/j.issn.1000-3428.2014.01.030 1 [1] (RFID)
