s101: the electronic device enters a boot mode based on the control instruction.
The electronic device is, but not limited to, a smart phone, a tablet computer, an electronic book, and the like.
Taking a smart phone with an android system as an example, the smart phone can be controlled to enter a guidance mode by sending an instruction (namely, a control instruction) to the smart phone, namely: fastboot mode.
In a specific example, an instruction may be sent to the smart phone through an external tool, such as a production tool used in producing the smart phone, so as to enable the smart phone to enter the fastboot mode.
S102: receiving an encryption instruction sent by a production tool, wherein the encryption instruction comprises identity information of the production tool, and the identity information is encrypted by the production tool in advance through a first encryption mode.

In a specific example, the encrypted instruction includes, but is not limited to, identity information of the production tool, the identity information being encrypted by the production tool in advance through a first encryption manner, where the identity information is used to identify the production tool, that is: through the identity information, it can be determined that only a production tool with a specific identity can encrypt the engineering mode of the electronic equipment. The identity information may be a serial number of the production tool, or the like, or may be a specific identifier agreed in advance.
In this example, the first encryption mode may be encryption by a private key of the production tool, and specifically, the identity information may be encrypted by the production tool in advance by the first private key of the production tool. In this case, the production tool may give the public key matching the first private key, i.e., the first public key, to the electronic device. Then, the electronic device can complete the decryption of the identity information through the first public key.
S103: and decrypting the identity information based on a first decryption mode agreed in advance, and encrypting the engineering mode of the electronic equipment based on the encryption instruction after the decryption is successful.

Specifically, the electronic device prestores a second public key of the decryption tool, so as to encrypt the authentication information through the second public key, and the decryption tool decrypts the authentication information through a second private key of the decryption tool matched with the second public key. Namely: the authorized decrypting tool informs the electronic device of the second public key of the authorized decrypting tool in advance, so that when the decrypting tool needs to decrypt the engineering mode of the electronic device, the electronic device sends authentication information to the decrypting work, and the authentication information is encrypted by the electronic device according to the second public key of the authorized decrypting tool, so that after the decrypting tool receives the authentication information, if the decrypting tool can decrypt through the second private key of the decrypting tool, the decrypting tool has the authority of decrypting the engineering mode of the electronic device.
