在物联网中要保证信息来源的准确真实性,就需要严格确保网络中接入设备的合法性.提出了1种全新的身份双向认证机制,通过对传感器节点的ID身份信息和初始工作状态信息进行认证来判断该节点身份的合法性.同时在终端基站引入了传感器节点信息表定时更换机制,对传感器节点的ID信息和工作状态信息进行实时更新.在传感器节点认证过程中加入了自动告警机制,后台基站显示认证中告警类型.当身份认证失败,基站控制端发送命令启用备用传感器节点,保证了信息采集的顺利及时进行.实验结果显示,该方案能够有效提高安全性,同时缩短认证响应时间.
In the Internet of things to ensure the accuracy of the authenticity of the source of information, we need to strictly ensure the legitimacy of access devices in the network.A new bi-directional identity authentication mechanism is proposed.Through ID sensor ID and initial working status information To verify the legitimacy of the identity of the node.At the same time, the terminal base station introduces a mechanism for the timing change of the sensor node information table to update the ID information and working status information of the sensor node in real time.At the same time, the automatic alarm mechanism is added in the sensor node authentication process , The backend base station displays the type of alarm in the authentication.When the identity authentication fails, the control end of the base station sends a command to enable the spare sensor node to ensure the smooth and timely information collection.Experimental results show that this solution can effectively improve the security and shorten the authentication response time .
