| 英文摘要 | Due to the limited of power sensors in smart home devices, how to ensure the identity of sensors and the security of the data transmission is a new challenge to be solved. Based on symmetric polynomial, this paper developed a new solution by using sensor paring table. Firstly, when a sensor sent message to server, the server identified this sensor by the related sensors, and stored the information of the related sensors in the sensor paring table. Then, these related sensors returned the reliability score to the local server. At last, there would be a score for each sensor. When the score was below a certain threshold, the sensor was proved to be abnormal, so as to be cleared timely. This method effectively solves the node identity security problem, and ensures the legitimacy of the access node. |
