Fig. 1 is a schematic flowchart of a device encryption method in an embodiment of the present application, where an execution main body of the method may be a terminal device, and as shown in fig. 1, the device encryption method may include the following steps:
and S101, acquiring an encryption command and generating an encryption control signal according to the encryption command.
In this embodiment, after acquiring the encryption instruction, the control device in the terminal device generates a corresponding control signal, where the encryption control signal is a control signal generated by the control device for the terminal device that needs to be encrypted currently, so as to encrypt the terminal device according to the control signal.
Optionally, the control device may adopt an Embedded Controller (EC), and be integrated on a main board of the terminal device.
In one embodiment, before step S101, the method may include: the terminal equipment acquires a key signal generated by user operation, detects the key signal, and generates an encryption instruction when detecting that the key signal meets a preset encryption triggering condition so as to facilitate the control device to generate an encryption control signal. For example, when a user presses the encryption key, a key signal is generated, and if the position of the key signal is detected to be the position of the preset encryption key, the detected key signal meets the preset encryption triggering condition. The encryption key includes, but is not limited to, a switch key, at least one key at a preset position, and the like.
Further, the encryption key may be further conditioned to obtain the encryption trigger condition, where the key pressing manner for setting the encryption trigger condition according to the encryption key includes, but is not limited to, pressing the encryption key a preset number of times, pressing the encryption key a preset duration, pressing the encryption key sequentially or simultaneously when there are at least two encryption keys, and the like, and the setting of the encryption trigger condition may also be any combination of at least two of the above key pressing manners. For example, the encryption trigger condition is obtained by pressing the a key twice and then pressing the B key twice, and the encryption trigger condition is obtained by simultaneously pressing the Ctrl + M combination key of the keyboard.
In one embodiment, after detecting that the key signal meets the preset encryption triggering condition, the method includes: the method comprises the steps of acquiring input information, generating a decryption trigger condition according to the input information, namely, confirming the decryption trigger condition required by decryption while encrypting, so that when a signal acquired by a control device meets the decryption trigger condition, a related decryption operation can be executed, namely, a second switch device is started for identity verification.
In one embodiment, after the encryption instruction is obtained, the encryption instruction can be verified to judge whether the identity of the current operator has the authority, and an encryption control signal is generated according to the encryption instruction after the authority is determined, so that the security of encryption control is improved, and the identity information of the current operator can be detected through the identity detection device.
The specific example is not limited, the preset encryption triggering condition is that the start key is pressed twice, the identification mode is fingerprint identification, when encryption is needed, the user presses the start key twice, a prompt is popped up to input a fingerprint interface, after the user inputs a fingerprint through fingerprint input equipment, the control device obtains the input fingerprint through the fingerprint input equipment and performs identity verification, and after the identity verification is successful, an encryption control signal is generated according to an encryption instruction, so that the disabling of the interactive equipment is realized.
In one embodiment, whether the encryption triggering condition is met or not can be judged according to the key signal and the current state of the terminal equipment, and then the encryption control signal is generated according to the encryption instruction, so that the security of encryption control is improved.
Specifically, by way of example and not limitation, when the current state of the terminal device is set to be a normal use state, that is, in a non-screen-locked state, the combination key Ctrl + M of the keyboard is pressed simultaneously to obtain an encryption trigger condition, and the identification mode is a password detection identity.
Specifically, for example but not by way of limitation, when the current state of the terminal device is set to be a screen locking state, the key is pressed twice to obtain an encryption trigger condition, the identification manner is fingerprint identification, taking a computer notebook as an example, when a user is executing USB flash disk data transmission or network file downloading under the screen locking of the computer notebook, and encryption is required, the user presses the key twice to pop up a prompt to enter a fingerprint interface, after the user enters a fingerprint through fingerprint entry equipment, the control device obtains the entered fingerprint through the fingerprint entry equipment, performs identity authentication, and after the identity authentication is successful, an encryption control signal is generated according to an encryption instruction, so that the disabling of the interactive equipment is realized, namely the data transmission equipment required by the operation is disabled.
And S102, controlling a first switch device to be closed according to the encryption control signal, wherein the first switch device is used for controlling a power supply to supply power to the interactive equipment.
In this embodiment, the control device controls the first switch device to be turned off according to the generated encryption control signal, so as to cut off the power supply of the interactive device, and stop the operation of the interactive device. It can be understood that, in the embodiment, starting with pure firmware, the encryption is directly implemented by powering off the first switching device interaction device, so as to achieve the purpose of disabling the terminal device, and thus, the encryption of the terminal device is implemented by physically isolating the input/output of the terminal device, thereby improving the encryption reliability, reducing the instability of encryption through software, avoiding the situation of encryption failure caused by the influence of corresponding virus change software on the terminal device, and integrally improving the information security of the terminal device.
In one embodiment, the interaction device includes, but is not limited to, an input device, a data transmission device, and the like. The input device includes but is not limited to a keyboard, a mouse, a touch screen, etc.; the data transmission device includes, but is not limited to, a USB interface, a TypeC interface, a network interface (RJ45 interface), and the like.
In one embodiment, as shown in fig. 2, after step S102, the method includes:
step S201, acquiring a decryption instruction, and generating a decryption control signal according to the decryption instruction;
in this embodiment, after acquiring the decryption instruction, the control device in the terminal device generates a corresponding control signal, where the decryption control signal is a control signal generated by the control device for the terminal device that needs to be decrypted currently, so as to perform decryption according to the control signal.
In one embodiment, before step S201, it may include: the terminal equipment acquires the current state of the terminal equipment and a key signal generated by user operation, and generates a decryption instruction when detecting that the current state and the key signal meet a preset decryption triggering condition so that the control device can generate a decryption control signal. For example, when the current state is that the PC is not locked and the PC is in an encrypted state, a decryption key is preset, and when a user presses the decryption key, a key signal is generated, and when the position of the key signal is detected to be the position of the preset decryption key, it is indicated that the detected key signal meets a preset decryption trigger condition. The current state includes, but is not limited to, an encryption state, a decryption state, a screen locking state, a normal use state, and the like; the decryption key includes, but is not limited to, a switch key, at least one key of a preset position, and the like.
Further, the decryption key may be further conditionally set to obtain the decryption trigger condition, where the key ways for setting the decryption trigger condition according to the decryption key include, but are not limited to, pressing the decryption key a preset number of times, pressing the decryption key a preset duration, and pressing the decryption key sequentially or simultaneously when there are at least two decryption keys, and the setting of the decryption trigger condition may also be any combination of at least two of the above key ways. For example, the decryption trigger condition is obtained by pressing the a key twice and then pressing the B key twice, and the decryption trigger condition is obtained by simultaneously pressing the Ctrl + M combination key of the keyboard.
Step S202, controlling a second switch device to be turned on according to the decryption control signal, wherein the second switch device is used for controlling a power supply to supply power to the identity detection equipment;
in this embodiment, the control device controls the second switch device to be turned on according to the generated decryption control signal, that is, turns on the identity detection device for identity authentication, so as to determine whether the currently operating user is legal through identity authentication. It can be understood that, in the embodiment, starting with pure firmware, the identity detection device is directly turned on through the second switch device to realize the identity verification of the current operating user, so as to achieve the purpose of whether the terminal device can be started, thereby improving the reliability during decryption and improving the information security of the terminal device. The identity detection device includes, but is not limited to, a camera, a keyboard, a fingerprint input device, and the like. It can be understood that above-mentioned camera can be used to face identification and detects the identity, and above-mentioned keyboard can be used to the password and detect the identity, and above-mentioned fingerprint is typeeed equipment and can be used to the fingerprint and detect the identity.
The specific example is not limited, the preset decryption triggering condition is that the start key is pressed twice, the identification mode is fingerprint identification, when decryption is needed, a user presses the start key twice to generate a decryption control signal, then the second switch device is controlled to be started, a prompt input fingerprint interface is popped up, after the user inputs a fingerprint through the fingerprint input device, the control device obtains the input fingerprint through the fingerprint input device and carries out identification verification, and after the identification verification is successful, the first switch device is controlled to be started, so that the forbidden of the interactive device is realized.
And step S203, acquiring the identity information acquired by the identity detection equipment, and controlling the first switch device to be turned on when the identity information meets the preset decryption condition.
In this embodiment, when the identity authentication passes, it indicates that the currently operating user is legal, and the control device controls the first switch device to turn on, so as to recover the power supply of the related interactive device.
Specifically, for example and without limitation, when the current state of the terminal device is set to be a normal use state, that is, in a non-screen-locked state, the combination key Ctrl + M is pressed at the same time to obtain a decryption trigger condition, and the identification mode is a password detection identity, taking a PC as an example, when a user normally uses the PC and needs decryption, the user presses the combination key Ctrl + M at the same time, the control device generates a decryption control signal, pops up a prompt password input interface according to the decryption control signal, after the user inputs a password through the keyboard, the control device obtains an entered fingerprint through a fingerprint entry device and performs identity verification, and when the identity information meets a preset decryption condition, the first switch device is controlled to be turned on, so that the interactive device is enabled.
Specifically, for example but not by way of limitation, when the current state of the terminal device is set to be a screen locking state, the key on the computer is pressed twice to obtain a decryption trigger condition, the identification mode is fingerprint identification, taking a computer notebook as an example, when a user needs to transmit data through an interface by using the computer notebook and needs to decrypt, the user presses the key on the computer twice, the control device generates a decryption control signal, a prompt is popped up according to the decryption control signal to enter a fingerprint interface, after the user enters a fingerprint through the fingerprint entry device, the control device obtains the entered fingerprint through the fingerprint entry device and performs identity verification, and when the identity information meets a preset decryption condition, the first switch device is controlled to be turned on, so that the interactive device is enabled, and a corresponding data transmission interface is enabled.
In the embodiment of the application, the encryption instruction is obtained to know that encryption operation is required currently, so that an encryption control signal is generated according to the encryption instruction, and the first switch device is controlled to be turned off according to the encryption control signal, and the first switch device is used for controlling the power supply to supply power to the interactive device. The starting state of the interactive equipment which can interact with the terminal equipment is controlled, and encryption is carried out in a physically isolated mode, so that the information security of the terminal equipment is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
