The invention discloses a process monitoring method, relating to the field of a process monitoring technology. The method comprises the following steps: S1: obtaining the API (application programming interface) address of NtCreateSection and replacing the original NtCreateSection with DetourNtCreateSection; S2: monitoring processes to be created according to the DetourNtCreateSection. The method provided by the invention can be used for intercepting the processes being created in the process of creation rather than after creation, thus enabling the system to be more secure. As the hooked sites are unavoidable paths for process creation, and can not be easily bypassed by Trojans, virus and the like. As a result, the safety can be ensured. In addition, the method is not as complicated as the HOOK ObReferenceObjectByHandle method, and only one API is hooked in the whole process, thus causing the process to be clear and easily understood. The NtCreateSection used in the method provided the invention is placed at a high inner core level and only intercepts processes being created, thus not affecting other valid processes in operation in the system.

The invention discloses a multi-container-based trusted application program processing method and related equipment, which are used for simplifying the development and deployment process of trusted application programs and improving the processing efficiency of the trusted application programs and the security of an access interface of a trusted execution environment. The method comprises the steps that a terminal performs integrity verification on a signed security computing unit through a security computing container; if the signed security computing unit passes the integrity verification, the terminal performs legality verification on the signed security computing unit through the security computing container and acquires a verification result; and if the verification result is legal, the terminal loads the signed security computing unit through a trusted execution environment (TEE) or a security element (SE) and acquires a security computing result of the trusted application.

The invention relates to an overpressure closing valve for high-pressure natural gas. The overpressure closing valve comprises a pressure sensing head, a locking release mechanism and a closing valve body, wherein the locking release mechanism is provided with a valve clack drive rod and a locking release component; a circumferential groove is formed on the valve clack drive rod; the locking release component is provided with a locking tab; a valve clack and the valve clack drive rod are fixedly connected; a valve clack spring is arranged between the valve clack and the valve body; and a valve port is formed below the valve clack; a pressure sensing skin membrane, a pressure presetting mechanism and a horizontal compression bar are arranged in the pressure sensing head; and the horizontal compression bar and the locking release component are fixedly connected. When unreasonable high pressure occurs in a pressure regulating system, the pressure sensing skin membrane is driven by the pressure, acts on the locking release mechanism through the horizontal compression bar, releases the valve clack drive rod, and allows the valve clack fixedly connected with the clack valve drive rod to drop down so as to seal the valve port. In the whole working process, delay time does not exist, gas is not diffused, pressure jump is avoided, the environment is protected, and safety effect is achieved.
