The target application may be applicable to Android, IOS, applet or H5 page.

It should be noted that the target application is the unique decryption application corresponding to the terminal device dynamically generated by the server background according to the verification information of the terminal device when the user authenticates the terminal device.

Specifically, when the user needs to know the original parameter information of the terminal device, the encrypted parameter information of the terminal device can be obtained by calling the downloaded target application to scan the information code on the terminal device.

S204, the calling target application uses the asymmetric encryption private key to decrypt the encrypted parameter information to obtain the original parameter information of the terminal device.

Specifically, when encrypting the original parameter information, the encrypted data can be obtained by encrypting the original parameter information with a symmetric encryption key, the encryption key can be obtained by encrypting the symmetric encryption key with an asymmetric encryption public key, and then the encrypted data can be obtained by encrypting the original parameter information with a symmetric encryption key.

Further, when the encrypted data and the encryption key are combined and spliced, the encrypted data and the encryption key can be spliced through special characters, for example, encrypted data.encrypted key. Among them, special characters are characters that are different from encrypted data and encrypted key characters. For example, if the encrypted data and the encryption key are both hexadecimal characters, the special characters are characters other than hexadecimal characters.

It can also be done by splitting the strings of encrypted data and encryption keys, then alternately combining each string. For example, the encrypted data are 1, 2, and 3; the encryption keys are A, B, and C; they can be alternately spliced into 1A2B3C. It is also possible to split the encrypted data and the encrypted character string into groups according to the same or different preset splitting rules, and split the encrypted data into the grouped string and the encryption key into the grouped characters.

The key is decrypted to obtain a symmetric key, and the encrypted data is decrypted using the symmetric key to obtain the original parameter information. For example, if the string of encryption key and encrypted data is spliced and combined by special characters, the special characters in the encryption parameter information can be searched, and the corresponding encryption key and encrypted data can be determined in the order of combination. data and encryption keys. Then use the asymmetric private key to decrypt the encrypted key to obtain the symmetric key, and then use the symmetric key to decrypt the encrypted data to obtain the original parameter information.

The public key is used to decrypt the encrypted data using the asymmetric private key corresponding to the asymmetric encryption public key to obtain the original parameter information. For example, if the string of encryption key and encrypted data is spliced and combined by special characters, the special characters in the encryption parameter information can be searched, and the corresponding encryption key and encrypted data can be determined in the order of combination. data and encryption keys. Then use the asymmetric private key to decrypt the encrypted key to obtain the symmetric key, and then use the symmetric key to decrypt the encrypted data to obtain the original parameter information.
