Problems solved by technology
The current security control methods usually use various security software, encryption systems, protection codes and other measures to prevent thieves from stealing data from the external interface of the device, but such methods cannot prevent the thieves from accessing the internal data after the device is opened. The storage medium is directly physically cracked to steal important information

The invention discloses a device safety control system and method based on self-destruction after opening the cover, wherein the system includes a trigger mechanism and a self-destruction unit; wherein the self-destruction unit includes a DC / DC module, a high-performance battery, a voltage stabilization module, FPGA, power-on and power-off control circuit, anti-short circuit detection circuit and encryption and decryption module; when the external cover is disassembled maliciously, the trigger mechanism will work, and the high-performance battery will be converted into 3.3v voltage, 2.5v voltage, 1.5v voltage, and output to FPGA; at the same time, FPGA detects the self-destruct detection information, and FPGA sends the destruction command to the encryption and decryption module; the encryption and decryption module clears the stored information after receiving the destruction command; after the FPGA sends the destruction command, clears its self-stored information. When the device is maliciously disassembled, the present invention can start a self-destruction program to destroy the key content and key information stored inside the device, preventing secret thieves from obtaining the information stored in the device by directly cracking the internal storage chip.
Description
technical field [0001] The invention belongs to the technical field of aerospace electronic systems, and in particular relates to a device safety control system and method based on self-destruction after opening the cover. Background technique [0002] Important information is generally stored on security-related devices. Once obtained by others, there is a risk of obtaining important information. Therefore, security control methods for such devices are very important. The current security control methods usually use various security software, encryption systems, protection codes and other measures to prevent thieves from stealing data from the external interface of the device, but such methods cannot prevent the thieves from accessing the internal data after the device is opened. The storage medium is directly cracked physically, thereby stealing important information. Contents of the invention [0003] The technical problem solved by the present invention is to overcome...
