The term "and/or" as used herein indicates that at least one of the items defined by the term, e.g., "a and/or B" may be implemented as "a", or as "B", or as "a and B".
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The technical solutions of the embodiments of the present application and technical effects produced by the technical solutions of the present application are described below by describing several exemplary embodiments. It should be noted that the following embodiments may be referred to, or combined with each other, and the description will not be repeated for the same terms, similar features, similar implementation steps, and the like in different embodiments.
First, several terms related to the embodiments of the present application are described and explained:
password (password): the tool corresponding to the user name and used for verifying whether the user name corresponds to the authority can be in various forms such as numbers, characters and figures. In daily life, the password is often called a password, but the password is strictly called a password. In the technical solution of the present application, if the password is encrypted, it is called "password".
Public-private key pair: the public-private key pair is a key pair obtained by an algorithm, and includes a public key and a private key. Wherein the secret key disclosed to the outside is called public key, and the secret key reserved by itself is called private key. The public and private key pairs obtained by this algorithm can be guaranteed to be unique worldwide. If one of the keys is used to encrypt a piece of data, then the other key must be used for decryption. For example, encrypting data using a public key must use a private key to decrypt the data, otherwise decryption will not succeed.
salt: in password protection technology, a salt is a random data string used to modify the password hash. At user enrollment, the random number generated by the system to be combined with the user password is referred to as the salt value, and is commonly referred to as the salified value. By adding the salt value to process the password, even if the original password set by the user is the same, the ciphertext corresponding to the original password is different. Adding a salt to the password hash also prevents an attacker from using dictionary words to verify the entire system, so that it is also possible to use a salt to implement a password hash matching policy to make it difficult for an attacker who attacks the system.
The embodiment of the application provides an unlocking method, as shown in fig. 1, which is applied to a first terminal and includes:

After receiving the remote unlocking request of the first terminal, the server acquires the first unlocking password from the second terminal and forwards the first unlocking password to the first terminal.
Specifically, the second terminal encrypts a pre-stored preset unlocking password of the first terminal according to a pre-stored preset public key and a first preset random number of the first terminal to obtain a first unlocking password, and forwards the first unlocking password to the first terminal through the server.
The preset public key is generated by the first terminal, the preset public key is prestored on the second terminal and used for encrypting the unlocking password, and the corresponding preset private key is prestored on the first terminal and used for decrypting the unlocking password.
The first preset random number can be a salt value, and the second terminal adds the first preset random number when encrypting the preset unlocking password by adopting the preset public key, so that the safety of the first unlocking password is improved, and repeated anti-cracking is ensured.
And step S103, decrypting the first unlocking password according to the preset private key and the second preset random number to obtain a first unlocking password.
After receiving the first unlocking password fed back by the server, the first terminal decrypts the first unlocking password according to the prestored preset private key and the second preset random number to obtain a first unlocking password.
The preset private key is matched with a preset public key prestored in the second terminal. The second predetermined random number is also a salt value.
It should be noted that, the process of decrypting the first unlock code is implemented inside the first device, and the whole decryption process is transparent to the user, without any operation by the user.
Step S104, unlocking processing is carried out according to the preset unlocking password and the first unlocking password.
The first terminal matches the decrypted first unlocking password with a pre-stored preset unlocking password, if the matching is successful, the first unlocking password is correct, and then the first terminal is unlocked.
