[0106] reference Figure 5 This is a specific implementation of a method for secure loading of a solid-state hard disk controller of the present invention, which is specifically as follows:
[0107] The firmware encryption process is explained as follows:
[0108] 1. The packaging tool randomly generates a 128bit random number as the random key KEY4.
[0109] 2. Join the 128-bit fixed key KEY3 and the random key KEY4 generated in process 1 to form a 256-bit complete key KEY5.
[0110] 3. Use the fixed key KEY3 to encrypt the header with AES128 to generate the ciphertext header.
[0111] 4. Use the complete key KEY5 in process 2 to encrypt the Bootloader with AES256 to generate the cipher text Bootloader.
[0112] 5. Join the ciphertext header in process 3 and the ciphertext Bootloader in process 4 to form a complete Bootloader firmware.
[0113] 6. Burn the Bootloader firmware into Flash.
[0114] The firmware decryption process is explained as follows:
[0115] 1. The chip is powered on and t
