Burning file encryption and decryption method and system based on address remapping

The invention discloses a burning file encryption and decryption method and system based on address remapping, and the method comprises the steps: carrying out remapping encryption of an address of aconventional sequence address of a burning file based on an encryption key and an encryption algorithm; wherein the instruction data is stored in the remapped and encrypted second address instead of the conventional sequence address, and the encryption and decryption method enables the input address and the output address of the burning file to uniquely correspond to each other in the encryption and decryption process. Encryption operation is carried out on the address, so that compared with conventional encryption operation processing on the instruction data, operation amount required by encryption is reduced, and chip operation efficiency and safety are improved. 本发明公开一种基于地址重映射的烧录文件的加解密方法及其系统，所述基于地址重映射的烧录文件的加解密方法是通过对烧录文件的常规顺序地址基于加密密钥和加密算法进行地址的重映射加密，指令数据由存储于常规顺序地址转而存储于重映射加密后的第二地址，该加解密方法使得烧录文件在加解密过程中输入的地址和输出的地址唯一对
