Abstract: A device for monitoring underwater surface overflow seepage of a landslide includes an underwater seepage monitor arranged on an underwater sliding mass, the underwater seepage monitor includes a bearing housing, a flow guide pipe, a silt discharging cover plate and a silt discharging mechanism, the silt discharging mechanism driving the silt discharging cover plate to be switched between a blocking position and an opening position. Considering complex environmental factors, a multifunctional flow monitor is embedded into a sliding mass and surrounds an outlet of the underwater landslide seepage. A silt discharging hole is provided in the bearing housing, the silt discharging mechanism is configured to drive the silt discharging cover plate to be located at the opening position, and silt in the bearing housing may be discharged from the silt discharging hole, such that the problem of silt deposition caused by overflow seepage of an underwater landslide is solved.

Abstract: The present disclosure relates to a device for laying out a prefabricated magnetic field and a method for responding state of a slip mass in the prefabricated magnetic field. The device may include a traction mechanism, a control mechanism and a layout probe. The layout probe may include a shell, a circuit board and at least one set of layout mechanism equipped in the shell. The layout mechanism may include a cartridge, a screw pole, an electromagnet, a driving mechanism and a pressing mechanism. The traction mechanism may lay down the layout probe to a default location of a drill hole. The control mechanism may control the driving mechanism to transmit an uppermost permanent-magnet in the layout probe to the cartridge nozzle and be attracted by the electromagnet. The pressing mechanism may move the electromagnet which presses the permanent-magnet in the inner wall of the drill hole.

Abstract: The present disclosure discloses a mask S-box, a block ciphers algorithm unit, a device and a corresponding construction method. The mask S-box includes an input module, an address mapping processing module, and an output module. The input module receives a random number and an input data which is masked by the random number and uses the random number and the input data as two inputs of the mask S-box. The address mapping processing module performs one-to-one mapping on the two inputs and the corresponding memory address of the mask S-box. The output module linearly processes the random number by using a linear function to obtain the linearly converted random number, which is used as one output of the mask S-box. The memory address obtained by using the linearly converted random number to mask the output of the original S-box is used as the other output of the mask S-box.

Abstract: The present invention discloses a bus monitor for enhancing SOC system security and a realization method thereof. The bus monitor disposed between a system bus and a system control unit includes a configuration unit, a condition judgment unit, an effective data selection unit, a hardware algorithm unit and a comparative output unit. Without affecting the bus access efficiency, the present invention provides the method capable of immediately monitoring the bus behavior, and the detection system notices whether a particular bus access serial behavior is changed due to an accidental fault or intentional attacking fault. If the particular bus access serial behavior is changed, the present invention warns the system to adopt a suitable security measure to prevent the security hidden trouble and leakage of classified information due to the incorrect system security process.
