Abstract: The present invention belongs to the field of automation equipment predictive maintenance, and relates to a method for diagnosing health of a CNC machine tool. Parameters such as vibration and temperature are detected by Zigbee nodes adopted in the present invention and uploaded to a Zigbee gateway. The detected data is transmitted by the Zigbee gateway to a cloud server for digital signal processing, data mining and analysis processing. After a training test of the above data is carried out by the cloud server, a health degree model is obtained. The health degree model is transmitted by the cloud server to the Zigbee gateway. A clock circuit can be used for synchronizing system time and recording time as data is recorded. For the on-line predictive maintenance of a CNC machine tool, the most rapid and accurate predictive maintenance information is provided.

Abstract: Disclosed is an identity authentication method. By means of the method, confidentiality processing is performed on identity information of a requesting device, to prevent the identity information of the requesting device from being exposed during a transmission process, thereby ensuring that an attacker cannot obtain private information of the requesting device. Moreover, by means of introducing an authentication server, identity authentication performed on the requesting device by an authentication access controller is realized while ensuring the confidentiality of information related to an entity identity, so as to ensure that only legitimate users can access a network. Further disclosed are an identity authentication apparatus, a storage medium, a program, and a program product.

Abstract: An identity authentication method and apparatus, a device, a chip, a storage medium, and a program. Confidentiality processing is performed on identity information of a requesting device and an authentication access controller, such that the identity information of the requesting device and the authentication access controller is prevented from being exposed during a transmission process, thereby ensuring that an attacker cannot obtain private and sensitive information of the requesting device and the authentication access controller. In addition, by means of involving an authentication server, mutual identity authentication of the requesting device and the authentication access controller is realized while the confidentiality of information related to an entity identity is ensured.
