Equipment safety control system and method based on uncapping self-destruction

Abstract

The invention discloses an equipment safety control system and method based on uncapping self-destruction. The system comprises a trigger mechanism and a self-destruction unit, wherein the self-destruction unit comprises a DC / DC module, a high-performance battery, a voltage-stabilizing module, a field programmable gate array (FPGA), a power-on / power-off control circuit, a short-circuit preventiondetection circuit and an encryption / decryption module; when an external cover plate is disassembled maliciously, the trigger mechanism works, and the high-performance battery converts to 3.3v voltage,2.5v voltage and 1.5v voltage through the voltage-stabilizing module, and outputs the voltages to the FPGA; meanwhile, the FPGA detects self-destruction detection information, and sends a destructioncommand to the encryption / decryption module; the encryption / decryption module clears stored information after receiving the destruction command; and the FPGA clears the self-stored information aftersending the destruction command. When equipment is disassembled maliciously, a self-destruction program can be enabled, and key content and key information stored inside the equipment are destructed,so that a stealer is prevented from getting information stored in the equipment by directly cracking an 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...
