Abstract: Disclosed are a protection method and a protection system of system partition key data and a terminal. The protection method includes: obtaining a verification table corresponding to key data carried in a system partition file when a bootloader is started, and decrypting a digital signature by using a preset public key or a private key to obtain a first verification value; generating a second verification value according to a block address and a hash value, and comparing the first verification value with the second verification value; and starting a system if the first verification value is consistent with the second verification value.
