一种嵌入式设备的自毁方法和存储设备

摘要：本发明涉及设备自毁领域，特别涉及一种嵌入式设备的自毁方法和存储设备。所述一种嵌入式设备的自毁方法，包括步骤S101：响应自毁模式指令；步骤S102：设备重启，启动引导程序读取引导程序通信块中的自毁信息；步骤S103：判断是否满足预设条件，若满足，则执行步骤S104，若不满足，则执行步骤S105或正常引导设备；步骤S104：执行第一预设操作；步骤S105：判断自毁模式是否为安静模式，若是，执行步骤S106，若否，执行步骤S107；步骤S106：执行第二预设操作，自毁完成；步骤S107：执行第三预设操作，自毁完成。通过以上步骤，能够将设备中flash存储介质的所有区域的用户数据(包括加密数据)和固件进行完全、彻底地销毁和破坏，保护用户数据和固件的安全。

Self-destruction method of embedded equipment and storage equipment

Abstract:The invention relates to the field of self-destruction of equipment, in particular to a self-destruction method of embedded equipment and storage equipment. The self-destruction method of the embedded device comprises the following steps of S101: responding to the self-destruction mode instruction; step S102: the equipment is restarted, and a bootstrap program is started to read self-destruction information in a communication block of the bootstrap program; step S103: judging whether a preset condition is met, if so, executing step S104, and if not, executing step S105 or normal booting equipment; step S104: executing a first preset operation; step S105: judging whether the self-destruction mode is a quiet mode, if so, executing step S106, and if not, executing step S107; step S106: executing a second preset operation, and completing self-destruction; step S107: and executing a third preset operation to finish self-destruction. Through the steps, the user data (including encrypted data) and the firmware in all areas of the flash storage medium in the device can be completely and thoroughly destroyed, and the safety of the user data and the firmware is protected.
