Referring to table 1, the following table is an example of a configuration information table:
| configuration item | Configuration value | Mode of operation |

Referring to fig. 2, as a modification of the above embodiment, the step S100 includes:
step S110, a Secure-Element (SE) of a terminal generates a group of RSA public and private key pairs, wherein the RSA public and private key pairs comprise private keys and public keys;
in one embodiment, the RSA public-private key pair is 2048 bits in length.
Step S120, the terminal stores the private key in the security chip and sends the public key to a terminal management platform;
wherein the private key is used for decryption; in an embodiment, the terminal sends the public key to the terminal management platform through a TLS secure communication protocol.
Step S130, after the terminal receives the encrypted configuration data sent by the terminal management platform, the terminal decrypts the encrypted configuration value by using a private key to obtain the decrypted configuration data; the encrypted configuration data is obtained by encrypting the terminal management platform according to a working mode set by a user, the user logs in the terminal management platform by adopting an authorized account, and the terminal management platform determines a terminal corresponding to the decrypted configuration data according to a product serial number;
step S140, the terminal analyzes the decrypted configuration data to obtain a configuration item and a configuration value of the configuration item.
In one embodiment, the configuration data includes configuration items and configuration values of the configuration items, after a user logs in the terminal management platform, the configuration values are set to the terminal management platform, and after the terminal management platform reads the configuration values for setting a working mode, the configuration values are encrypted by using a public key, and the encrypted configuration values are sent to the terminal; the configuration value obtained by the terminal decryption is plaintext data; and the terminal determines a working mode according to the configuration value, and switches to the working mode when executing the task of the configuration item.
It can be understood that the terminal and the terminal management platform in the embodiment are required to be normally networked; in this embodiment, only after the authorization of the terminal is obtained, the configuration information table of the configuration partition can be written, the working mode of the terminal is defaulted to be the product mode, and if the working mode is to be switched to the authentication mode or the development mode, the authorized account needs to be used to log in the terminal management platform for setting switching.
As a modification of the above embodiment, the preset configuration information table is obtained by:
step S210, setting a writing configuration item interface and a reading configuration item interface for reading and writing the configuration information table;
step S220, when the terminal acquires the configuration data, opening the configuration information table through a configuration item writing interface, and analyzing to obtain all configuration items contained in the configuration information table;
step S230, writing the configuration values in the configuration data into corresponding configuration items to obtain a preset configuration information table.
It should be noted that the configuration data may be default values configured in a unified manner when the terminal leaves a factory; or after the terminal leaves the factory, the personalized configuration value input by the user needs to be updated to the personalized configuration value input by the user, and when the configuration value is updated, the working mode is correspondingly switched.
In some embodiments, by designing the API interface for writing configuration items and the API interface for reading configuration items, reading and writing configuration items are facilitated. For example, the API interface for writing configuration items is defined as write _ configx (), and the API interface for reading configuration items is defined as read _ configx (), where x in configx is the number of the configuration item, such as config1, config2, config3, and the like.
As a modification of the above embodiment, the step S220 further includes:
step S221, when the terminal acquires the configuration data, determining whether the configuration data exists in the configuration information table;
step S222, when the configuration data does not exist in the configuration information table, updating the configuration information table, and adding the configuration data which does not exist in the configuration information table into the configuration information table;
it should be noted that, when the personalized customization data is input by the user, it is first determined whether both the configuration item and the configuration value in the configuration data exist in the configuration information table; when the personalized customization data input by the user contains configuration data which does not exist in the configuration information table, when the terminal acquires the configuration data (the personalized customization data input by the user), newly adding the configuration data which does not exist in the configuration information table into the configuration information table, and newly adding configuration items and/or configuration values; when a configuration value is added, a corresponding working mode is added.
In some embodiments, assuming that the original compiled system only supports 3 configuration items, and the configuration data includes a new configuration item and a corresponding configuration value, the system needs to be upgraded for the newly added configuration item and the corresponding configuration value, and if the original compiled system cannot perform corresponding processing on the newly added configuration item, the original system needs to be upgraded and updated, and the upgraded system can execute the newly added configuration item, and the new configuration item and the corresponding configuration value are meaningful; and executing a corresponding working mode on the configuration item according to the newly added configuration value.
As a modification of the above embodiment, the step S200 includes:
step S201, when the terminal receives the action of running the configuration item, reading the preset configuration information table from the configuration partition through a configuration item reading interface;
step S202, analyzing and obtaining all configuration items in the preset configuration information table and configuration values corresponding to the configuration items, and matching the configuration items in the configuration data from the preset configuration information table;
step S203, updating the existing configuration value of the configuration item to the configuration value in the configuration data, and determining the working mode of the configuration item according to the configuration value.
In this embodiment, the configuration values of the configuration partition may be read at the stages of starting and loading lk (littlekernel), entering a real-time operating system (Kernel), and running a system (system), so as to obtain the current working mode of the terminal, and perform corresponding processing on the system.
After the working mode is changed into a non-product mode, the working mode needs to be switched into the product mode again for the sake of safety, and the product mode can be recovered to the authentication mode by a plurality of methods; as a modification of the above embodiment, after step S300, the method further includes: the terminal responds to the mode recovery condition and recovers the working mode of the terminal into a product mode;
the mode recovery condition includes at least one of:
the terminal receives the recovery action that the recovery working mode set by the user is a product mode;
for example, after the terminal is successfully switched to the non-product mode, the terminal can be actively restored to the product mode through the setting of the terminal, and the mode is convenient for the user to restore.
The terminal receives recovery information which is sent by a terminal management platform and used for recovering the working mode to be the product mode; the recovery information is obtained by encrypting the terminal management platform according to a recovery action set by a user, the user logs in the terminal management platform by adopting an authorized account, and the terminal management platform determines a terminal corresponding to the recovery information according to a product serial number;
that is, after receiving a recovery action set by a user, the terminal management platform queries a corresponding terminal through a unique serial number, sends the recovery action to the terminal, and the terminal recovers a working mode to a product mode; this approach facilitates platform unified management.
And the terminal determines that the working time of the switched working mode reaches a set threshold value.
For example, when the application switching operation mode is the non-product mode, the application switching operation mode may be applied for the operation time of the switched operation mode, such as 1 week, half month, 1 month, and the like, and the operation time may be configured and set according to the actual product requirement. When the working time of the switched working mode reaches a set threshold value, switching the working mode of the terminal into a product mode;
