摘要 智能家居设备中大部分传感节点计算能力较弱,而如何保证节点身份合法和数据传输安全是一个急需解决的新问题。基于对称多项式,提出一种匿名节点配对打分机制的认证方案。该方案预先在本地服务器生成节点之间的随机配对表,当节点向服务器发送消息时,首先通过配对表向相关联节点发送有服务器标志的认证信息,关联节点根据此认证消息分析是否含有自己的身份信息,然后返回给服务器该节点的身份可靠度分数,服务器进一步收集信息并计算该节点的可靠系数。当该系数低于一定的阈值时,则证明节点异常,从而及时清除该节点。该方案有效地解决了传统对称多项式加密被暴力破解而引发的节点身份安全问题,保证了接入节点的合法性。

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.
