The invention belongs to the technical field of artificial intelligence, and discloses a safety communication system and method of a generative artificial intelligence enabled internet of things, and the system comprises a registration authority which is responsible for registering an internet of things user and internet of things equipment; the Internet of Things user registers with the registration authority by using the smart phone, interacts with the edge artificial intelligence after logging in, and controls the remote intelligent device through the edge artificial intelligence; the intelligent device is used for collecting data in the environment and transmitting the data to the edge artificial intelligence and the Internet of Things user after mutual authentication; the edge artificial intelligence is an edge server close to the intelligent equipment, and an artificial intelligence application is deployed in the edge server and is fusion of edge calculation and artificial intelligence. According to the invention, the secure communication between the Internet of Things user and the remote intelligent device is mainly realized, and a weak physical unclonable function is embedded in the remote intelligent device in order to protect the physical security of the remote intelligent device.

The invention provides a high-altitude safety protection device which comprises a monitoring terminal and a control terminal. The monitoring terminal is used for collecting state information of the target safety hook lock and executing a corresponding control action on the target safety hook lock according to a received control instruction; and the control terminal is used for evaluating the high-altitude safety protection condition according to the collected state information of the target safety hook lock, generating corresponding warning information according to an evaluation result, and outputting a corresponding control instruction to the monitoring terminal according to the input control information. According to the invention, the safety protection problem of high-altitude operation in the power distribution network is solved, and the safety protection function of integrating an anti-double-solution function, a high-hanging low-action alarm function, a continuous single-hook operation alarm function and a remote monitoring terminal is realized; accident risks caused by misoperation are identified and intercepted through intelligent monitoring, and meanwhile, ground safety management personnel are remotely notified of field conditions at the first time, so that necessary measures can be taken in time.

The invention discloses a method and device for ensuring the security of a Selinux file, and the method comprises the steps: reading a signed security policy file from a file system of a user space when the security policy file needs to be updated; performing signature verification on the signed security policy file, and obtaining a new security policy; and after the signature verification is passed, the original security policy is unloaded, and then the new security policy is loaded to the Selinux kernel. By utilizing the scheme of the invention, the configuration information and the security policy of the Selinux can be ensured to be loaded and updated trustingly, and an attacker is prevented from bypassing security protection at a kernel level of an operating system by modifying a Selinux configuration file or a security policy file.

The utility model provides a protective fence, which relates to the technical field of building construction protection and comprises a base, the base is of a rectangular block structure, an inserting groove of a rectangular groove structure is formed in the top end face of the base, and a protective frame plate of a rectangular frame plate structure is arranged right above the base. An inserting block body of a rectangular block body structure is fixedly installed on the bottom end face of the protection frame plate, and the inserting block body is inserted into the inserting groove in a sliding mode. When a non-worker intends to cross the protective fence to enter a building construction area, and the hand of the non-worker presses the protective frame plate as a support and prepares to cross the protective frame plate, the position between the base and the protective frame plate is synchronously changed, so that the crossing warning switch is synchronously pressed and started, and high-decibel buzzing warning is realized in the first time; the problem that according to a traditional protective fence, when non-staff intends to cross the protective fence to enter a building construction area, warning and deterring cannot be achieved for the non-staff is solved.
