Abstract

The invention discloses a device anti-dismantlement device and a device with an anti-dismantlement function, comprising: an anti-dismantlement detection circuit whose output terminal is connected to a controller in the device, and is used to detect in real time whether the device is damaged when the conventional power supply of the controller is powered. Disassembly, so that the controller no longer executes the normal operation sequence after receiving the detection result of the device being disassembled; the backup power circuit is used to supply power to the tamper detection circuit after the conventional power supply is cut off, so as to facilitate tamper detection The circuit continues to detect in real time; and provides the controller with the power it needs to receive the detection that the device has been disassembled. It can be seen that the device anti-dismantlement device of the present application can continue to detect even after the conventional power supply is cut off, thereby improving the confidentiality performance of functional information and application security performance of the device.

Description

technical field

[0001] The invention relates to the field of anti-disassembly detection, in particular to an equipment anti-disassembly device and equipment with anti-disassembly function. Background technique

[0002] At present, for some manufacturers of confidential equipment, the confidentiality of the functional information of the equipment is extremely important. If the equipment is disassembled by others, it may cause the leakage of functional information, and at the same time, the application security of the equipment cannot be guaranteed at this time. Therefore, in order To prevent equipment from being disassembled, equipment anti-disassembly devices have gradually developed. In the prior art, there are two kinds of equipment anti-dismantlement devices: the first one is a physical anti-dismantlement device, such as a high-strength structural lock to prevent the equipment from being disassembled by others, but the physical anti-dismantlement device cannot detect whet...
