摘　　要：密钥是加密设备的核心信息,全方位保证密钥的安全意义重大。密钥通常存储在加密设备内的FLASH中,当机箱盖板被打开后,容易被人取出其中的FLASH芯片进行读取以获取其中的密钥信息。针对加密设备在需要紧急撤离无法带走且设备断电情况下,如何保证设备中的密钥安全,本论文设计了一种支持断电情况下,机箱盖板一旦被非法打开,密钥信息自动进行销毁的方案。The key is the core information of the encryption device,and it is of great significance to ensure the security of the key in all aspects.The key is usually stored in the FLASH in the encryption device.When the chassis cover is opened,it is easy to take out the FLASH chip and read it to obtain the key information.In view of how to ensure the security of the key in the encryption device when the encryption device needs emergency evacuation and cannot be taken away and the device is powered off,this paper designs a scheme to support the automatic destruction of the key information once the chassis cover is unlawfully opened in the case of power failure.
