The application provides a high-efficiency covert channel attack and information leakage method based on multiple interrupt driving, which is called Compound-INT. Four stable and controllable interrupt types (rtc0, PMI (Performance Monitor Interrupts), MCP (Machine Check Polls), IWI (IRQ Work Interrupts), and TLB (TLB shootdowns)) are screened out by analyzing the / proc / interrupts interface in an operating system to construct an efficient covert channel. The method supports two transmission modes, single bit and multi-bit. Single bit realizes data coding by controlling the interrupt triggering frequency, and multi-bit combines synchronous and asynchronous transmission modes to improve bandwidth and anti-interference, and adapt to the complex conditions of a multi-core environment. In addition, the application realizes the leakage of the existence state of a target file in a restricted directory by using the PMI interrupt, and speculates the structure information of a deep neural network (DNN) model by using the TLB shootdowns interrupt mode, thereby expanding the application scenarios of the covert channel. Experimental results show that the method has high transmission rate, low error rate and strong robustness, and provides a new idea for the security research of the interrupt mechanism of an operating system.

This application relates to a control method, intelligent switching gateway, and medium based on cloud-based PLC and local PLC. The control method employs a dual-redundancy system composed of cloud-based and local PLCs. The intelligent switching gateway selects whether to output a first control instruction from the cloud-based PLC or a second control instruction from the local PLC to the field actuators based on network communication status. Furthermore, when the cloud-based PLC acts as the master controller, the first control instruction and first status data are synchronized to the local PLC. The local PLC can update the second status data during the standby control logic operation based on the first status data. When the network communication status does not meet preset requirements and the local PLC is switched to the master controller, a smooth switch can be achieved, ensuring the continuity and stability of system operation. While utilizing the performance advantages of cloud-based PLCs, this method avoids the risk of control interruption due to network problems and reduces the cost and complexity of traditional dual-local PLC redundancy.
