Firmware encryption method, firmware decryption method and related devices

The invention provides a firmware encryption method, a firmware decryption method and related devices, and relates to the technical field of equipment management. The firmware encryption method comprises the following steps: firstly, encrypting a compressed original executable file to obtain reference firmware; and then, performing verification information addition processing on the reference firmware to obtain the target firmware to be sent to the firmware receiving end, thereby avoiding the risk that the original executable file is directly used as the firmware to be cracked and identified. 本发明提供的一种固件加密方法、固件解密方法及相关装置，涉及设备管理技术领域。所述固件加密方法：首先，对经压缩处理后的原始可执行文件进行加密处理，得到基准固件；然后，对基准固件进行校验信息添加处理，得到待发送给固件接收端的目标固件，从而避免了直接将原始可执行文件作为固件而存在的被破解和识别的风险。
