Description

Terminal encryption method, system and storage medium
Technical Field
The present invention relates to the field of terminal encryption technologies, and in particular, to a terminal encryption method, system and storage medium.
Background
Currently, for the sake of security, mobile terminal manufacturers generally do not allow SIM cards of other manufacturers to use the network after inserting into the mobile terminals of the manufacturers, and therefore, the SIM cards need to be encrypted. The existing encryption or locking modes are two types: firstly, reading the IMSI in the SIM card and then judging whether a plurality of IMSI numbers in the SIM card meet the use condition, if so, allowing the SIM card to be used; secondly, the SIM card user or provider and the operator agree, the network can be used only if the IMEI number of the mobile terminal is uniquely matched with the IMSI number of the SIM card, and the network can not be used if other cards are inserted into the mobile terminal.
However, the existing terminal encryption method may limit the use of the SIM card. For example, when all mobile terminals of a manufacturer can only use a customized card, and a customized SIM card can be replaced and used at will on different mobile terminals of the manufacturer, the existing encryption method cannot satisfy the above scenario, which is a very common situation. Therefore, an encryption method with higher flexibility and capable of enabling the SIM card to be suitable for different mobile terminals of corresponding manufacturers on the premise of ensuring the security of the SIM card is needed.

if the key is turned on, encrypting the unique identification code through the preset encryption algorithm to obtain the PIN code, and unlocking through the PIN code;
and if the SIM card is not unlocked, automatically inputting an original PIN code corresponding to the SIM card for unlocking, and updating the unlocking PIN code of the PIN code lock after the unlocking is successful.
3. A terminal encryption method according to claim 2, wherein before acquiring the unique identification code of the inserted SIM card, the method further comprises:
and setting the PIN code lock, wherein the PIN code lock corresponds to the unique identification code of the customized SIM card.
4. A terminal encryption method according to claim 1, characterized in that after the unlocking failure, the method further comprises:
encrypting the unique identification code again through the preset encryption algorithm to obtain a new PIN code, and unlocking through the new PIN code;
and if the continuous unlocking fails within the preset times, locking the SIM card.
5. A terminal encryption method according to claim 1, characterized in that: the unique identification code is ICCID data and/or IMSI data.
6. The terminal encryption method according to claim 1, wherein the unlocking the SIM card by the PIN code specifically comprises:
automatically sending the PIN code to the SIM card for unlocking; or
And displaying the PIN code, and sending the PIN code input by the user to the SIM card for unlocking.
7. A terminal encryption system, comprising:
the acquisition module is used for acquiring the unique identification code of the inserted SIM card;
the encryption module is connected with the acquisition module and used for encrypting the unique identification code through a preset encryption algorithm to acquire a corresponding PIN code;
and the unlocking module is connected with the encryption module and used for unlocking the SIM card through the PIN code, executing a network registration process if the unlocking is successful, and forbidding the network registration if the unlocking is failed.
8. The terminal encryption system according to claim 7, further comprising:
the judging module is used for judging whether the PIN code lock corresponding to the SIM card is opened or not;
if the unique identification code is started, the unique identification code is encrypted through the encryption module to obtain the PIN code, and the unlocking module is used for unlocking;
and if the SIM card is not unlocked, automatically inputting an original PIN code corresponding to the SIM card for unlocking, and updating the unlocking PIN code of the PIN code lock after the unlocking is successful.
9. The terminal encryption system according to claim 8, further comprising:
and the setting module is used for setting the PIN code lock, and the PIN code lock corresponds to the unique identification code of the customized SIM card.
10. A storage medium, characterized by: the storage medium has stored therein at least one instruction, which is loaded and executed by a processor to implement the operations performed by the terminal encryption method according to any one of claims 1 to 6.
