Description
Technical Field
The present disclosure relates to the field of data security transmission technologies, and in particular, to a secure system switching method and apparatus, an electronic device, and a computer-readable storage medium.
Background
Under the existing mobile communication mechanism, electronic devices such as mobile terminals generally transmit information collected by information input devices to a communication opposite end in a plaintext form without any processing, so that plaintext data can be directly obtained when a third party steals or intercepts the information. Since it is impossible to prevent third parties from stealing or intercepting due to the characteristics of mobile communication technology, research has been conducted only on how to make the stolen or intercepted data meaningless.
Encryption is a simple and easy method with obvious effect, data transmitted under a mobile communication mechanism is encrypted in a certain mode before transmission, so that the data is transmitted under a mobile communication network in a form of ciphertext, and even if the data is stolen or intercepted by a third party, a stack of meaningless messy codes can be obtained due to the fact that a correct decryption mode is not available.
In the related art, an electronic device capable of transmitting data in a ciphertext form is usually obtained by a built-in encryption program or an additional encryption chip, and can select an encryption mode or an non-encryption mode according to actual conditions, but another problem to be faced by an electronic device having two data processing modes is how to safely switch between an encryption mode and a non-encryption mode. Once the switching mode is set badly or a bug exists, the encryption mode is easy to separate from the encryption mode in a mode that the user does not know the malicious program, and therefore an attacker can conveniently obtain plaintext data.
Therefore, how to separate the encryption mode from the non-encryption mode in a more secure and reliable scheme to ensure the secure transmission of data as much as possible is a problem to be solved by those skilled in the art.

Detailed Description
The core of the application is to provide a secure system switching method, a device, an electronic device and a computer readable storage medium, the system switching method is applied to an electronic device with dual systems, namely a secure system for transmitting information acquired by an information input device in a ciphertext mode and a general system for transmitting the information in a plaintext mode, and is different from the prior art.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Example one
Referring to fig. 1, fig. 1 is a flowchart of a system switching method applied to an electronic device according to an embodiment of the present disclosure, and it should be noted that the electronic device applied in the scheme provided in this embodiment is an electronic device having two systems, namely, a security system and a general system, specifically, the electronic device in the security system sends information acquired by an information input device to a correspondent node in a form of a ciphertext; the electronic equipment under the general system can send the information collected by the information input device to the opposite communication terminal in a plaintext form. Of course, the electronic device can be used not only as an information sending device, but also as an information receiving device, namely, the received ciphertext is decrypted by using the security system, and the received plaintext is directly transmitted to the user by using the general system. Namely, the electronic device can be flexibly switched between an encryption system and a non-encryption system in different application scenes, and the scheme is a method for switching between the two systems more safely, and comprises the following steps:
s101: respectively acquiring state information output by a virtual control switch and an entity control switch to obtain first state information and second state information;
the step aims to acquire state information respectively output by a virtual control switch and an entity control switch on the electronic equipment, wherein the state information output by the virtual control switch is represented by using first state information and the state information output by the entity control switch is represented by using second state information.
Wherein the virtual control switch is a control switch provided by an operating system installed in the electronic device and used for switching between the security system and the general system. Specifically, the virtual control switch may be provided by a pre-installed operating system itself, or may be provided by an application program, a plug-in, an executable script, and the like installed in the operating system at a later stage; the entity control switch is any one of an entity pressing control switch, a touch control switch, a sliding control switch and the like arranged on the electronic equipment, can be an accessory entity control switch which is developed by an interface (such as a Mini-USB, a Type-C, a 3.5mm earphone interface and the like) capable of establishing physical data connection with the electronic equipment and can be arranged at any position of the electronic equipment flexibly according to the requirements of actual application scenes.
The specific implementation forms of the virtual control switch and the virtual control switch are not particularly limited, whether the physical hardware is a defining condition for distinguishing the virtual control switch from the physical control switch or not is determined, the number of the virtual control switch and the physical control switch is not limited, and the most appropriate specific parameters can be selected according to the actual application scene.
The expression form of the state information is various, and may be at least one of various forms such as a character string, an electrical signal, and a control instruction, which can be used to represent different states.
S102: and simultaneously, determining whether to switch the system in which the information input device in the electronic equipment is positioned from the security system to the general system or not according to the first state information and the second state information.
On the basis of S101, in this step, it is determined whether a system in which the information input device is located needs to be switched from the security system to the general system according to the specific state parameters of the acquired first state information and the acquired second state information, so that the system can be switched only when the state information output by the two control switches both meets the corresponding preset requirements, and further encrypted transmission is realized under the security system, and plaintext transmission is realized under the general system.
The information input device is various devices used for collecting externally input information in the electronic device, and comprises a camera, a microphone and a keyboard, and correspondingly, the types of the information which can be respectively collected are image information, voice information and character information. The purpose of changing the system where the information input device is located is to change the subsequent processing mode of various output information, because the security system is additionally provided with an encryption step and other auxiliary steps related to encryption processing compared with a general system, namely, the system is switched to, the processing mode of which system is used to process the information acquired by the information input device and finally the information is transmitted to the opposite communication terminal.
Specifically, the judgment condition of whether the system in which the information input device is located can be switched from the security system to the general system can be preset, for example, the same preset requirement can be set for specific parameters of the state information output by the virtual control switch and the entity control switch, that is, when the first state information and the second state information are consistent with the unified preset requirement, the security system can be switched to the general system; different preset requirements can be set for specific parameters of the state information output by the virtual control switch and the entity control switch respectively, and the safety system can be switched to the general system only when the first state information and the second state information correspondingly meet the corresponding preset requirements at the same time. The specific selection is flexible according to the requirements in the actual application scenario, and is not specifically limited herein.
It should be noted that, in order to ensure that data of the user of the electronic device can be transmitted safely as much as possible, the electronic device is in the security system by default, that is, the information input device is connected to the security system by default, and encrypts the information acquired by the information input device by default, and transmits the information to the correspondent node in the form of a ciphertext. Therefore, this step will focus on how to break away from the security system to a general-purpose system that does not perform encryption processing with stricter requirements.
Further, if the condition of breaking away from the safety system to the general system is met through judgment, the judgment is continuously carried out, and if the condition of breaking away from the safety system is not met any more, the safety system is switched back in time to ensure the safety of data transmission.
Based on the above technical solution, the system switching method provided in this embodiment of the present application is applied to an electronic device with dual systems, which are a secure system for transmitting information acquired by an information input device in a ciphertext form and a general system for transmitting information in a plaintext form, and is different from the prior art, the present disclosure simultaneously adopts a plurality of parameters with different sources as determination conditions for determining whether to disengage from a secure system to the general system, specifically, state information output by a virtual control switch and state information output by an entity control switch, and if to disengage from the secure system, the state information output by the two types of switches must be tampered simultaneously, and the two types of switches are provided from software and hardware angles, and meanwhile, different tampering modes must be used for different types of control switches, and the purpose of disengaging from the secure system cannot be achieved only by a single tampering mode, so that data transmission is safer.
Example two
Referring to fig. 2, fig. 2 is a flowchart of another system switching method applied to an electronic device according to an embodiment of the present disclosure, and compared with the first embodiment, the present embodiment provides a specific way for determining whether inter-system switching can be performed, which specifically includes the following steps:
s201: respectively acquiring state information output by a virtual control switch and an entity control switch to obtain first state information and second state information;
the procedure S101 is the same and has no change, and the related description information can refer to S101, which is not described herein again.
S202: judging whether the first state information and the second state information simultaneously and correspondingly meet a first preset requirement and a second preset requirement;
that is, one of the two preconditions preset for judging whether the state information output by the virtual control switch satisfies the disengagement safety system is a first preset requirement, and the other one of the two preconditions preset for judging whether the state information output by the entity control switch satisfies the disengagement safety system is a second preset requirement. In other words, the first status information corresponds to a first predetermined requirement, the second status information corresponds to a second predetermined requirement, and the step is to determine whether the first status information satisfies the first predetermined requirement, whether the second status information satisfies the second predetermined requirement, and whether both of the first status information and the second status information satisfy the first predetermined requirement and the second predetermined requirement.
S203: switching the system in which the information input device is located from the security system to a general system;
this step is established on the basis that the two determinations are simultaneously satisfied as a result of the determination in S202, that is, the condition for switching the system in which the information input device is located from the security system to the general system is satisfied, which indicates that the user of the electronic device has undergone double authentication, and needs to change the data transmission method by himself or herself with a high probability, so that the operation of switching the system in which the information input device is located from the security system to the general system can be performed.
S204: keeping the system where the information input equipment is currently located as a safety system unchanged;
this step is established on the basis that the judgment result of S202 is that the two judgments are not simultaneously satisfied, and specifically includes the following possibilities: the first state information does not meet a first preset requirement, and the second state information meets a second preset requirement; the first state information meets a first preset requirement, and the second state information does not meet the second state information; the first state information does not meet the first preset requirement, and the second state information does not meet the second preset requirement. The condition that the system where the information input device is located is switched from the security system to the general system is not met, and the condition that the state information output by the virtual control switch is tampered after the electronic device is maliciously invaded or the state information output by the entity control switch is maliciously adjusted by other people, so that the scheme can fully defend the maliciously modifying the data processing mode of the electronic device in the existing stealing or intercepting mode.
S205: judging whether the first state information and the second state information simultaneously and correspondingly meet a first preset requirement and a second preset requirement;
in step S203, the present step monitors whether or not the condition for switching the security system to the general-purpose system is continuously satisfied (the condition is consistent with the judgment condition in step S202), and if not, switches back to the security system again.
S206: keeping the current system of the information input equipment as a general system unchanged;
this step is based on the result of the determination in S205 that both determinations are satisfied at the same time, that is, it is said that the condition for switching the security system to the general system is currently well maintained, and therefore the system where the information input device is currently located is kept unchanged.
S207: and switching the system where the information input device is located from the general system back to the security system.
This step is based on the result of the determination in S205 that the two determinations are not simultaneously satisfied, that is, it is described that the condition for switching the security system to the general system is not well maintained, and thus it is described that the condition for switching the security system to the general system is no longer satisfied, and it is necessary to switch the system where the information input device is located from the general system back to the security system, so as to ensure the secure transmission of data as much as possible.
The embodiment provides a mode for comprehensively judging whether the system where the information input device is located can be switched from the safety system to the general system by combining the virtual control switch and the entity control switch at the same time through the technical scheme, and timely switches the system where the information input device is located back to the safety system by monitoring whether the judgment condition after the information input device is switched to the general system is changed or not in real time, so that a safer system switching method is provided, and the safe transmission of data is more fully guaranteed.
EXAMPLE III
Referring to fig. 3 and fig. 4, fig. 3 is a schematic structural diagram of an or gate circuit for enabling an electronic device to safely switch between different systems according to an embodiment of the present disclosure; fig. 4 is a flowchart of a switching method based on an or gate circuit according to an embodiment of the present disclosure, and this embodiment is a specific implementation manner of the second embodiment, and achieves this purpose by means of a special characteristic of the or gate circuit, including the following steps:
s401: the first electric signal and the second electric signal are respectively used as an input signal of an OR gate circuit;
as shown in fig. 3, the state information output by the virtual control switch will serve as a first electrical signal when embodied as an electrical signal, the state information output by the physical control switch will serve as a second electrical signal when embodied as an electrical signal, and the first electrical signal and the second electrical signal are respectively used as one input signal of the or gate circuit.
The special characteristics of the or gate circuit to be used in the present embodiment will be described herein, the or gate circuit is a logic circuit in the form of the or gate circuit labeled in fig. 3, which exists as a specific gate circuit for implementing the or operation in the logic operation process, or when the or operation is applied to the representation of the electrical signal, the or gate circuit has the characteristics that, of two input terminals, as long as the electrical signal input at any one input terminal is at a high level (logic "1"), the or gate circuit has a unique output terminal which outputs an electrical signal at a high level (logic "1"); only when the electrical signals input at the two input terminals are all low (logic "0"), the electrical signal output at the output terminal is low (logic "0"), as shown in table 1:
TABLE 1 OR gate output correspondence table
| Virtual control switch output | Physically controlled switch output | Output of OR gate circuit |
| High level of voltage | High level | High level |
| High level of voltage | Low level of electricity | High level |
| Low level of electricity | High level | High level of voltage |
| Low level of electricity | Low level of electricity | Low level of electricity |
S402: judging whether the output signal of the OR gate circuit is at a low level;
on the basis of S401, in this embodiment, whether the electrical signal output by the or gate circuit is at a low level is used as a determination condition for determining whether the system in which the information input device is located can be switched from the security system to the general system, which can be obtained according to table 1, the or gate circuit outputs a low level and requires the virtual control switch and the physical control switch to output a low level, it should be noted that the electrical signals output by the virtual control switch and the physical control switch are both at a high level by default, that is, to switch the system to the general system, the virtual control switch and the physical control switch are required to simultaneously adjust the level states of the electrical signals output by the virtual control switch and the physical control switch to a low level, thereby implementing double verification and stricter system switching.
S403: switching the system in which the information input device is located from the security system to a general system;
this step is based on the determination result of S402 being that the electrical signal output by the or gate circuit is at a low level, and therefore satisfies the condition for switching the system in which the information input device is located from the security system to the general system.
S404: keeping the system where the information input equipment is currently located as a safety system unchanged;
this step is based on the determination result of S402 being that the electrical signal output by the or gate circuit is at a high level, and therefore the condition for switching the system in which the information input device is located from the security system to the general system is not satisfied, and the system in which the information input device is currently located will continue to be kept unchanged as the security system.
S405: judging whether the output signal of the OR gate circuit is at a low level;
this step is based on S403 and is intended to determine whether or not a condition that does not satisfy the hold under the general-purpose system has occurred, i.e., whether or not the output signal of the or gate circuit is low level is still determined.
S406: keeping the current system of the information input equipment as a general system unchanged;
this step is established on the basis that the determination result of S405 is that the electrical signal output by the or gate circuit is still at the low level, which indicates that the condition for continuing to be maintained in the general system is satisfied, and therefore the system in which the information input device is currently located will be maintained as the general system.
S407: and switching the system in which the information input device is positioned from the general system back to the safety system.
This step is based on the determination result in S405 that the electrical signal output by the or gate circuit is no longer at the low level but is changed to the high level, which indicates that the condition for continuing to remain in the general-purpose system is no longer satisfied, and therefore the step of switching the system in which the information input device is located from the general-purpose system back to the security system is performed.
The present embodiment provides a specific implementation manner in a lower embodiment of the second embodiment by means of the characteristics of the or gate circuit.
Example four
On the basis of any of the above embodiments, this embodiment will describe the above process in combination with the influence of the difference of the interface where the electronic device is located on the state information output by the virtual control switch, and it should be understood that, taking the intelligent mobile terminal as an example, the following interface scenarios are included: the screen locking state, the standby state, and the use state may be further subdivided according to the mode (for example, a silent mode, a ready mode, a ring mode, and the like), that is, the specific parameter of the state information output by the virtual control switch is related to the interface and the scene where the electronic device is located, and specifically, the specific parameter of the state information output by the virtual control switch may be adjusted according to the identification mark of the interface where the virtual control switch is located. Furthermore, in order to realize automatic switching, different identification marks can be preset for different interfaces and scenes in advance, the identification marks are used for reference conditions when the virtual control switch outputs state information, and a corresponding relation table comprising corresponding relations between each identification mark and corresponding state information output by the virtual control switch is established, so that the state information output by the virtual control switch can be automatically adjusted subsequently according to the corresponding relation table.
The following use scenarios may be specifically included: when a user does not use the mobile phone, the mobile phone is in a standby state and a screen locking state, dials a private phone or performs private service processing, the state information output by the virtual control switch is controlled to be a high-level electric signal, no matter what state information is output by the entity control switch, the high-level electric signal is always output under the action of an OR gate circuit, and at the moment, information input equipment such as a camera and a microphone of the mobile phone is taken over by a security system, the acquired information is encrypted under the security system, and the information is transmitted to a communication opposite end in a ciphertext mode. And the switch is switched to the general system only when the state information output by the manual adjustment virtual control switch is in a low level and the physical control switch outputs the low level through the manual adjustment.
Because the situation is complicated and cannot be illustrated by a list, a person skilled in the art can realize that many examples exist according to the basic method principle provided by the application and the practical situation, and the protection scope of the application should be protected without enough inventive work.
