Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
With the development of electronic technology, mobile terminals have been commonly used. The core of the mobile terminal is an operating system on top of which a user can install various applications. If the mobile terminal is used for a long time and too many applications are installed, the mobile terminal may have problems of low processing speed, too much memory occupation and the like. At this point, the user may select a flush. The function of the mobile terminal can be more complete by flashing, and the mobile terminal can be restored to the original state. Sometimes, the damage of an operating system of the mobile terminal causes function failure or cannot be started, and the problem can be solved through flashing.
In the related technology, the flashing process does not need to verify whether a person who conducts the flashing operation is the user, so that if the mobile terminal is stolen by other people, various passwords set by the original user can be deleted through flashing, and the safety of the mobile terminal is affected. Therefore, how to improve the security of the flash is an urgent problem to be solved.
In the present disclosure, a first level bootstrap program is run; detecting whether the value of a first flag bit in a primary bootstrap program is a first value; the first flag bit indicates whether the flash is allowed or not, and the first value indicates that the flash is allowed; the first flag bit is stored in a separate storage area; when the value of the first flag bit is a first value, a secondary bootstrap program is operated; performing security authentication through a secondary bootstrap program; and when the security authentication is passed, running a flashing bootstrap program. The bootstrap program in this disclosure refers to a short program executed by the system itself after the mobile terminal is started, and the bootstrap process is completed by the system, and after the terminal is started, the bootstrap program is used to input a small amount of instructions and data, and then the instructions and data are input into other programs, and this process is called bootstrap. By adopting the scheme provided by the disclosure, the flashing bootstrap program is started to run when the value of the first flag bit in the primary bootstrap program is the first value and the security authentication is passed, namely the flashing bootstrap program can be run after the mobile terminal passes the double verification, so that the safety of flashing is improved by improving the bootstrap program.
Fig. 1 is a flowchart illustrating a method of controlling a flash according to an exemplary embodiment, which may be implemented by a mobile terminal, as shown in fig. 1, and includes the steps of:
in step S101, a primary boot program is executed;
in step S102, detecting whether a value of a first flag bit in a primary boot program is a first value; the first flag bit is stored in a separate storage area;
in step S103, when the value of the first flag bit is the first value, the secondary boot program is executed;
in step S104, security authentication is performed by the secondary boot program;
in step S105, when the security authentication is passed, the flush boot program is executed.
In this embodiment, when the user is flashing, the mobile terminal first runs the primary bootstrap program, and detects whether a value of the first flag bit in the primary bootstrap program is a first value.
Wherein, the first flag bit indicates whether the flash is allowed or not; the first flag bit has two values, the first value is used for indicating that the flash is allowed, the second value is used for indicating that the flash is not allowed, for example, the first value is true, and the second value is false; or the first value is 0 and the second value is 1. In the related art, the first flag bit indicating whether the flush is allowed is not included in the primary boot program.
The value of the first flag bit in the primary bootstrap program is defaulted to be the second value, so that if the user of the flash is a local user, the value of the first flag bit needs to be modified to be the first value through the operating system. In addition, the first flag bit is stored in a separate storage area, which may be a secure chip separate from the memory chip, and the configuration file storing the flag bit may be encrypted.
When the value of the first flag bit is a first value, a secondary bootstrap program is run, and the secondary bootstrap program is used for performing security verification, wherein the specific verification process is as follows:
before security verification, the mobile terminal is bound in advance with a specific account number, which may be registered by the user or provided by the manufacturer of the mobile terminal. The username for the particular account is saved in the first bootstrap after binding. When the specific account is provided by the mobile terminal manufacturer, the mobile terminal manufacturer provides the user name and the initial verification code of the specific account at the same time, and the user can modify the initial verification code.
The secondary bootstrap program provides a function of connecting a wireless network, after the secondary bootstrap program is operated, an input box of a verification code is popped up, the input box of the verification code is used for inputting the verification code corresponding to a pre-bound account, wherein, during security verification, a user name corresponding to the account can not be displayed, so when other users want to update the mobile terminal, as the user name of the account bound by the mobile terminal can not be obtained, the password corresponding to the user name can not be found through other channels, therefore, the security of the mobile terminal can be further improved without displaying the user name, and the secondary bootstrap program obtains a specific account pre-bound by the user through the primary bootstrap program. In the verification process, the verification code input by the user is sent to the server through the function of the wireless network, and the verification result fed back by the server is received.
And when the verification code input by the user is correct, the safety certification is passed. And when the security authentication is passed, normal flashing operation can be carried out, and the mobile terminal starts to run a flashing bootstrap program.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: when the value of the first flag bit in the first-level bootstrap program is the first value and the security authentication passes, the flashing bootstrap program is started to run, namely the flashing bootstrap program can be run after the mobile terminal passes the double verification, so that the safety of flashing is improved by improving the bootstrap program.
In one embodiment, as shown in fig. 2, after the above step S102, the method may further be implemented as the following step S201:
in step S201, when the value of the first flag bit is the second value, the operating system is run; wherein the second value indicates that a flush is not allowed.
And when the value of the first flag bit is a second value which does not allow the flash, operating the operating system, namely not entering a second bootstrap program, and not performing the flash operation but performing the normal boot operation. When the user sets the screen locking password, the mobile terminal can be operated only by inputting the screen locking password after the mobile terminal is started, so that the user who does not know the screen locking password cannot modify the value of the first zone bit. And because the value of the first flag bit in the primary bootstrap program is defaulted to the second value, and a user who does not know the screen locking password cannot modify the value of the first flag bit, the user who does not know the screen locking password cannot modify the value of the first flag bit from the default second value to the first value, and only can perform the on-off operation.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: when the flag bit is the second value which does not allow the machine refreshing, the operating system is operated, so that a user who does not know the screen locking password can not refresh the machine by changing the value of the first flag bit, and the safety of the machine refreshing is improved.
In one embodiment, as shown in fig. 3, before the above step S101, the method may further be implemented as the following step S301:
in step S301, receiving, by an operating system, an input setting operation on a first flag bit; the setting operation includes setting a value of the first flag bit to a first value.
Since the value of the first flag bit in the primary boot program defaults to the second value that is not allowed to be refreshed, in the present embodiment, a modification function of the first flag bit in the primary boot program for indicating whether to allow the flashing is provided. Therefore, if the user who wants to swipe the phone is the local user, after the screen locking password is input for unlocking, the value of the first flag bit can be modified to the first value through the operating system. If the user who wants to power on the mobile terminal is other users, the user cannot enter the operating system of the mobile terminal for operation because the user does not know the screen locking password, so that the value of the first flag bit cannot be modified from the default second value to the first value, and only the power on/off operation can be performed.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: the setting operation of the first flag bit can be received through the operating system, so that the user of the computer knowing the first value can perform the flashing operation.
In one embodiment, as shown in fig. 4, after the above step S104, the method may further be implemented as the following step S401:
in step S401, when the security authentication fails, the value of the first flag is set to a second value by the secondary boot program.
If the user does not set the screen locking password for the mobile terminal or the screen locking password of the mobile terminal is cracked by other users, and if other users want to flush the mobile terminal, the mobile terminal can enter the security authentication stage through the verification of the primary bootstrap program. Sometimes, a user who cannot pass the security authentication attempts to pass the security authentication by repeatedly attempting the security authentication, and according to the scheme provided by this embodiment, the user who cannot pass the security authentication needs to reset the value of the first flag bit every time the user attempts to pass the security authentication, which increases the difficulty in deciphering the security authentication.
Or, when the security authentication is not passed for a plurality of times (for example, 3 times), the value of the first flag bit is set to the second value by the secondary boot program. The user may not input the verification code correctly due to hand mistake, and the security authentication fails, so that the user is allowed to try the security authentication for multiple times, and when the multiple attempts fail, the value of the first flag bit is set to be the second value. However, the number of allowed attempts is not necessarily excessive.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: when the security authentication fails, the value of the first flag bit is set to be the second value through the secondary bootstrap program, so that the condition that the machine is refreshed by other users when the value of the first flag bit is defaulted to be the first value is avoided, and the security of the machine refreshing is improved.
In one embodiment, as shown in FIG. 5, the above step S104 can be implemented as the following steps S501-S503:
in step S501, an input verification code is received, and a user name corresponding to the verification code is not displayed in the interface;
in step S502, matching the received verification code with the verification code corresponding to the pre-bound user name; the pre-bound user name is obtained from a primary bootstrap program;
in step S503, when the verification codes match, it is confirmed that the security authentication is passed.
Before step S501, an input box of the verification code may be output without displaying the user name; in step S501, the input authentication code is received through the input box.
Before security verification, the mobile terminal is bound with a specific account in advance, and the specific account can be registered by the user or provided by the manufacturer of the mobile terminal. When the specific account is provided by the mobile terminal manufacturer, the mobile terminal manufacturer provides the user name and the initial verification code of the specific account at the same time, and the user can modify the initial verification code.
After the secondary bootstrap program is run, popping up an input box of a verification code, wherein the input box of the verification code is used for inputting the verification code corresponding to the pre-bound account, and the user name corresponding to the account can not be displayed during security verification.
After receiving the verification code input by the user through the popped-up input box, matching the received verification code with the verification code corresponding to the user name of the pre-bound account. The secondary bootstrap program provides the function of connecting the wireless network, so the verification code can be sent to a server of a mobile terminal manufacturer, the server matches the verification code with the verification code corresponding to the user name bound in advance by the mobile terminal manufacturer, and when the verification code is always matched, the security authentication is passed.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: when the security authentication is carried out, only the verification code input box is displayed, but the user name is not displayed, so that the condition that after other people know the user name, the passwords corresponding to the user name are obtained through other channels is avoided, and the security of the machine-refreshing is further improved.
In one embodiment, the method further comprises:
and encrypting the first flag bit, so that the first flag bit can be accessed only by the primary bootstrap program, the secondary bootstrap program or the appointed application program of the operating system, and can be changed only by the secondary bootstrap program or the appointed application program of the operating system. For example, the configuration file where the first flag bit is located is encrypted and stored in a separate secure chip. The Encryption process can also be realized by a security chip in a hardware Encryption mode, and the Encryption method can adopt a known Data Encryption mode such as DES (Data Encryption Standard) Encryption. The first flag bit is encrypted at the time of shipment. Before detecting whether the value of the first flag bit is the first value in step S102, the first flag bit is decrypted. If the value of the first flag bit is modified, encryption needs to be performed again after the modification. To improve safety.
The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: through the encryption of the first zone bit, the safety of the first zone bit can be improved, the first zone bit is not easy to modify, and the safety of the flash is further improved.
