And S102, initializing equipment hardware related to unlocking operation in the running of the kernel bootstrap program.
The method comprises the steps of realizing starting unlocking operation based on equipment hardware on the electronic equipment, wherein different unlocking modes are different corresponding to the equipment hardware needing to be used.
For example, if the unlocking operation is password unlocking, a touch unit and a display unit are needed, a password input interface is displayed through the display unit, and a password is input on the password input interface through the touch unit to unlock the password;
the unlocking operation is unlocking of the secret card and the secret bar, a communication unit, the secret card and the secret bar are needed to be used, data interaction is carried out between the secret card and the secret bar, an interaction result of the data interaction between the secret card and the secret bar is obtained through the communication unit, and unlocking is achieved according to the interaction result;

the unlocking operation is face unlocking, a camera unit is needed, and the face is collected through the camera unit to unlock.
In the kernel boot stage, each device hardware of the electronic device is not initialized yet and cannot work normally, and in order to realize the startup unlocking operation in the kernel boot stage, the device hardware which needs to be utilized in the startup unlocking process needs to be initialized first, so that the device hardware can work normally.
And S103, executing an unlocking operation based on the initialized equipment hardware to obtain an unlocking result.
The device hardware can normally work after the initialization is finished, and different unlocking operations are executed by using different device hardware to obtain an unlocking result.
S104, judging whether the unlocking result is successful or not;
if the unlocking result is judged to be successful, executing the step S105;

And S105, continuing to run the kernel bootstrap program and starting the operating system.
And after the unlocking operation is completed and the unlocking is determined to be successful in the kernel boot stage, continuing to run the kernel boot program and starting the operating system so as to normally start the computer.

Because the startup unlocking operation is completed in the kernel boot stage, and the operating system of the electronic equipment is not started to operate in the kernel boot stage, the condition that an illegal user acquires the root authority is avoided, and the startup unlocking safety of the electronic equipment is improved.
The unlocking method provided by the embodiment is described in the application scenario of password unlocking by using an unlocking operation, and as shown in fig. 2, the method includes the following steps:
s201, running a kernel bootstrap program after the electronic equipment is powered on.
The implementation manner of step S201 in this embodiment is similar to that of step S101 in the previous embodiment, and is not described here again.
S202, initializing an input unit and a display unit during the running of the kernel bootstrap program.
The password unlocking mode is that the received password input by the user on the password input interface is compared with a preset unlocking password, if the received password input by the user is the same as the unlocking password, the unlocking is successful, and if not, the unlocking is failed.
And initializing a display unit such as a liquid crystal display screen in the kernel boot stage for displaying a password input interface. The password input interface at least comprises a password input box, and the password input box is used for presenting a password input by a user.
The kernel boot phase also initializes the input unit for receiving user input. The input unit comprises a touch screen, a physical key, a keyboard and the like, and different electronic devices have different input units, so that the initialized input units are different for different electronic devices.
For example, an electronic device with a touch function initializes a liquid crystal display and a touch panel in a kernel boot phase. In addition to the password input frame and the virtual keys, the virtual keys may be numeric keys or character keys, for example, the virtual keys are presented by an input keyboard of an input method, and a user may switch the virtual keys according to actual needs. And the user directly touches the virtual key to realize the input of the unlocking password. As shown in fig. 3, a schematic view of a password input interface displayed on a liquid crystal display of the electronic device with a touch function in this embodiment is shown, where the password input interface includes a password input box, virtual number keys, and prompt information.
For another example, the electronic device without a touch function initializes the liquid crystal display and the physical key or the keyboard and other input units at the kernel boot stage, and only the password input box can be displayed in the liquid crystal display, so that the user can input the unlocking password through the physical key or the keyboard.
And S203, displaying a password input interface through the display unit.
In different types of electronic equipment, password input interfaces displayed by the display unit are different. The password input interface displayed by the electronic equipment with the touch function comprises a password input frame and virtual keys, and the password input interface displayed by the electronic equipment without the touch function only comprises the password input frame.
And S204, receiving the input operation of the user on the input unit.
If the input unit is a touch screen, the received input operation is touch operation; the input unit is an entity key or a keyboard, and the received input operation is a pressing operation of the entity key.
And S205, determining password information input by the user based on the input operation.
And if the input operation is a touch operation, respectively acquiring touch position information of each touch operation, and determining password information input by a user based on the touch position information.
The virtual keys corresponding to different touch positions are different, and the corresponding virtual keys can be determined according to the touch positions, so that the password input by the user can be determined.
It should be noted that the correspondence between the touch position and the virtual key may be fixed, that is, the position of the virtual key included in each password input interface is fixed.
After touch operations of a user are received, touch position information of each touch operation is obtained, virtual keys corresponding to each touch operation are determined according to the corresponding relation between the fixed touch positions and the virtual keys, and therefore passwords input by the user are determined.
The corresponding relationship between the touch position and the virtual key can also be changed, and the position of the virtual key included on the password input interface is changed each time. After touch operations of a user are received, touch position information of each touch operation is obtained, virtual keys corresponding to each touch operation are determined according to the corresponding relation between the current touch position and the virtual keys, and therefore the password input by the user is determined.
If the input operation is the pressing operation of the entity keys, key information of each pressed entity key is respectively obtained, and the key information is password information input by a user.
S206, judging whether the password information input by the user is the same as the unlocking password or not to obtain an unlocking result; if the password information input by the user is judged to be the same as the unlocking password, the unlocking result is successful; and if the password information input by the user is different from the unlocking password, the unlocking result is unlocking failure.
The unlocking password is a character string arranged according to a specific sequence, wherein the character string comprises numbers, letters, symbols and the like. And after the password information input by the user is determined, sequentially comparing whether each element in the character string is respectively the same as the element at the current position in the unlocking password. And if the password input by the user is the same as the unlocking password, determining that the unlocking is successful, otherwise, failing to unlock.
S207, judging whether the unlocking result is successful;
if the unlocking result is judged to be successful, executing step S208;
if the unlocking result is judged to be unlocking failure, the electronic equipment is shut down or dormant, and the electronic equipment cannot be normally started, so that the problem of important information leakage caused by acquiring the important information from the electronic equipment is avoided, and the safety of the electronic equipment is improved.
And S208, continuing to run the kernel bootstrap program and starting the operating system of the electronic equipment.
In other embodiments, after receiving an input operation of the user at the input unit, the method may further include:
judging whether input operation of a user for executing preset times on the input unit is received within preset time; the preset number of times may be the same as the total number of elements constituting the character string of the unlock password, or may be set in consideration of the number of times that the user can complete the input operation within a certain time.
If the unlock code is "8457", the predetermined time is set to 2 minutes and the preset number of times is 4. The setting mode can save the subsequent judging steps for judging the password input by the user and the unlocking password, and if the number of times of receiving the input operation of the user in 2 minutes is not equal to 4, the password input by the user is determined to be different from the unlocking password, so that the unlocking failure can be directly determined.
And only if the number of times of receiving the input operation of the user is equal to 2 within the confirmed 2 minutes, determining the password information input by the user according to the input operation, and judging whether the password information input by the user is the same as the preset unlocking password or not. If the password information input by the user is judged to be the same as the preset unlocking password, the kernel bootstrap program is continuously run and the operating system of the electronic equipment is started to realize normal startup by executing the step S208. And if the password information input by the user is different from the preset unlocking password, adding 1 to the error number of the input password, if the error number of the input password after adding 1 does not exceed the error threshold (for example, 5), returning to the step S204 and the subsequent steps, and if the error number of the input password after adding 1 exceeds the error threshold, shutting down the computer.
For example, the unlock password is "8457", and the preset time is 10 seconds and the preset number is 3, considering that the number of touch operations or physical key pressing operations that the user can complete within 10 seconds is generally 3. Considering that if the user is not the user of the electronic device but other users want to use the electronic device, there is a means for cracking the password when inputting the password, which inevitably results in that the input operation is not executed smoothly, so that the time for completing the input operation is long.
The unlocking method provided by the embodiment is described in the application scene of unlocking the secret card and the secret bar, and as shown in fig. 4, the unlocking method comprises the following steps:
s401, the electronic equipment runs a kernel bootstrap program after being powered on.

The polling command is typically sent to the communications unit by the Application Processor (AP) after a set interval of 11 seconds.
Optionally, in this embodiment, the communication unit is a satellite module.
