Correspondingly, the target terminal installs the application based on the application information when receiving the application information sent by the first terminal, and the method includes the following steps: and the target terminal decrypts the signature based on the first public key under the condition of receiving the application information to obtain application installation information, and installs the application based on the application installation information. Wherein the first public key corresponds to the first private key.

In the embodiment of the application, because the first private key is private to the first server, and the other servers do not have the first private key, the first server encrypts the application installation information based on the first private key to obtain a signature, and sends the application information including the signature, after the target terminal obtains the application information including the signature, once the first public key can unlock the signature, the application information is sent by the first server, so that the application information sent by the target terminal by an illegal server can be prevented from being installed, and the safety of application installation is improved.

In a possible implementation manner, the application information further includes a certificate, and the certificate is obtained by encrypting the first public key based on the second private key of the target terminal. Correspondingly, when the target terminal receives the application information, the signature is decrypted based on the first public key to obtain the application installation information, which includes: the target terminal decrypts the certificate based on a second public key corresponding to the second private key under the condition that the application information is received, and a first public key is obtained; and decrypting the signature based on the first public key to obtain the application installation information. The second private key and the second public key are a pair of keys, only the second public key can unlock information encrypted by the second private key, and only the second private key can unlock information encrypted by the second public key.

Optionally, in this embodiment of the application, the second public key and the second private key are generated by a second server, and after the second server generates the second public key and the second private key, the second server stores the second private key in the second server to improve the security of the second private key, and sends the second public key to the target terminal, so that the target terminal can verify the validity of the application information based on the second public key.

In one possible implementation manner, the application information includes a signature and application installation information, and the signature is obtained by encrypting a first hash value of the application installation information based on a first private key of the first server. Correspondingly, the target terminal installs the application based on the application information when receiving the application information sent by the first terminal, and the method includes the following steps: and the target terminal decrypts the signature based on the first public key under the condition of receiving the application information to obtain a first hash value of the application installation information. The target terminal performs hash processing on the application installation information to obtain a second hash value; in a case where the first hash value is the same as the second hash value, the application is installed based on the application installation information.

In the embodiment of the application, in consideration of the fact that the application information may be changed by an illegal server in the transmission process, the first hash value of the application installation information is encrypted to obtain a signature, and the application installation information and the signature are carried in the application information. Because the hash values generated by different application information are different, the target terminal only needs to perform hash processing on the application installation information, and compares the obtained second hash value with the first hash value in the signature, so that whether the application information is changed can be determined, thereby avoiding the installation of the application corresponding to the illegally changed application information in the target terminal, and improving the safety of application installation.

Optionally, after receiving the application information, the second terminal does not verify the application information, and directly forwards the application information to the second server, and the second server verifies the validity of the application information, and after receiving verification passing information returned by the second server, the first terminal installs the application based on the application information.

If the target terminal installs the application based on the application download link, the target terminal needs to determine whether the target terminal is currently in a connection state with the internet, and if the target terminal is in the connection state, the target terminal directly installs the application based on the application download link. Alternatively, the target terminal stores the application download link in a case where the target terminal is not connected to the internet, and waits until the target terminal is in a connected state with the internet, and then installs the application based on the application download link. Optionally, in a case where the target terminal installs the application based on the application download link, the target terminal uses an HTTPS (hypertext Transfer Protocol over Secure Socket Layer) to obtain information associated with the application download link.

The internet communication module is used for communicating with the first server and obtaining the application information from the first server.

In the embodiment of the application, multiple types of application information are provided, so that the first terminal can determine the type of the acquired application information according to actual conditions. Under the condition that the target terminal is connected with the Internet, the first terminal acquires the application information comprising the application download link and sends the application information to the target terminal, and the consumption of communication resources of the first terminal can be reduced due to the fact that the data size of the application download link is small. Under the condition that the target terminal is not connected with the Internet, the first terminal acquires application information comprising the application installation package and sends the application information to the target terminal, so that the target terminal can install the application under the condition that the target terminal is not connected with the Internet.

In the embodiment of the application, the certificate is generated based on the second private key of the target terminal, the second private key is private to the target terminal, and other terminals do not have the second private key, so that the first server carries the certificate in the application information, after the target terminal acquires the application information including the certificate, once the second public key can unlock the certificate, the certificate is generated by the first private key, and the first public key in the certificate is the public key of the legal server.

In the embodiment of the application, in consideration of the fact that the application information may be changed by an illegal server in the transmission process, the first hash value of the application installation information is encrypted to obtain a signature, and the application installation information and the signature are carried in the application information. Because the hash values generated by different application information are different, the target terminal only needs to perform hash processing on the application installation information, and compares the obtained second hash value with the first hash value in the signature, so that whether the application information is changed or not can be determined, thereby avoiding the installation of the application corresponding to the illegally changed application information in the target terminal and improving the safety of application installation.
