Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In the prior art, most of the factory restoration settings for the electronic device can be determined and executed by a user of the electronic device. Some electronic devices require a user to input authentication information such as password or fingerprint, and only when the authentication information is legal, the user can enter the system of the electronic device, but once the electronic device enters the system, the user can start the electronic device to restore the factory settings. In the prior art, the control terminal may also control the electronic device to restore factory settings through a corresponding network, but whether a user corresponding to the control terminal is a user of the electronic device or an owner of the electronic device cannot be confirmed.
Therefore, in some special cases, for example, when the electronic device is stolen, the thief can restore the electronic device to the factory setting without verifying the consent of the device owner, thereby causing the device owner to lose control over the electronic device. For another example, the owner of the electronic device leases the electronic device to other users, and the leased user may also directly restore the electronic device to the factory setting without the consent of the owner of the electronic device, but the owner of the electronic device loses the control right of the electronic device, which causes a certain loss. Therefore, how to guarantee the rights of the owner of the electronic device and improve the safety of the electronic device in restoring factory settings becomes an important technical problem.
Fig. 1 is a flowchart of a method for restoring factory settings according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
s101, the control terminal generates a production setting recovery request message and sends the factory setting recovery request message to corresponding target equipment.
Wherein, the factory reset request message at least comprises: and restoring the factory setting instruction, the equipment identity identification and the first confusion value. The first confusion value may be obtained by encrypting the factory reset instruction and the device identifier by the control terminal according to a preset algorithm and a preset first key.
For example, the factory reset Command is Command, the device ID is ID, and the first key is K1The predetermined algorithm is F1Then the first alias value C1＝F1(K1,Command||ID)。
The device identity is an identity of the target device and is used for uniquely identifying the target device. The device identity and the first key may be pre-stored in the control terminal, or may be input by the user to the control terminal, which is not limited in the embodiment of the present application.
The control terminal here refers to a terminal device used by an electronic device owner, and may be an electronic device with network communication capability, such as a smart phone and a tablet computer. The target device is an electronic device that performs factory reset.
S102, the target device determines the device identity in the factory reset request message, and the device identity is consistent with the identity of the target device.
The target device may first determine whether the device identity in the factory reset request message is consistent with the identity of the target device; in case of coincidence, the next step is executed again.
Through the scheme, the target device can determine the factory reset request message corresponding to the target device.
And S103, the target device verifies the first confusion value in the received factory setting restoration request message based on a preset rule.
In some embodiments of the present application, the verification of the first obfuscated value based on a preset rule may be implemented according to a method as shown in fig. 2:
and S201, the target device encrypts the factory resetting instruction and the device identity in the factory resetting request message according to a preset algorithm and a preset second secret key to obtain a second confusion value.
In this application, the second obfuscation value is obtained by encrypting, by the target device, the factory reset instruction and the device identifier in the factory reset request message based on the preset algorithm and the preset second key.
For example, the preset algorithm in the target device is F2The second secret key is K2If the factory reset Command in the factory reset request message is a Command and the device identifier is an ID, the second confusion function C is used2＝F2(K2,Command||ID)。
It should be noted that the second key and the preset algorithm in the target device may be stored in the target device in advance, and the second key and the preset algorithm may be fixed parameters and cannot be changed. Also, the preset algorithm mentioned here is an encryption algorithm.
S202, the target device determines whether the first obfuscated value and the second obfuscated value in the factory reset request message are consistent.
For example, where the first confusion function is C1The second confusion function is C2In the case of (1), judgment is made of1And C2Is the same.
S203, determining that the first obfuscated value passes verification under the condition that the first obfuscated value is consistent with the second obfuscated value; in the event that the first obfuscated value is not consistent with the second obfuscated value, it is determined that the first obfuscated value failed verification.
In the above scheme, the target device may encrypt the factory resetting restoration instruction and the device identity in the received factory resetting request message according to a preset algorithm and the second key, so as to obtain a second confusion value. That is to say, based on the preset algorithm and the second key in the target device and the preset algorithm and the first key in the control terminal, the factory reset request message is subjected to security verification, and compared with directly sending the first key, the encrypted first obfuscated value can effectively prevent other malicious users from intercepting the corresponding key, and the security of the key is enhanced.
In some embodiments of the present application, the verifying the first obfuscated value based on a preset rule may also be implemented according to a method as shown in fig. 3:
s301, based on a preset algorithm and a preset second secret key, decrypting the first confusion value in the factory setting restoration request message to obtain a corresponding equipment identity.
And after receiving the factory setting restoration request message, the target device calls a pre-stored preset algorithm and a preset second secret key. And decrypting the first confusion value through a pre-stored preset algorithm and a preset second key so as to obtain a corresponding equipment identity.
For example, the predetermined algorithm is D, and the second key is K2The first confusion value is C1Then, we can get: (Command ID) ═ D (K)2,C1) Wherein: the Command is a factory reset Command, and the ID is equipment identity.
S302, determining whether the decrypted equipment identity is consistent with the equipment identity in the factory reset request message.
And the target equipment determines the equipment identity in the factory-reset request message, compares the equipment identity with the equipment identity obtained after decryption, and determines whether the equipment identity and the equipment identity are the same.
S303, determining that the first confusion value is verified under the condition that the decrypted equipment identity is consistent with the equipment identity in the factory setting restoration request message; and under the condition that the equipment identity obtained after decryption is consistent with the equipment identity in the factory reset request message, determining that the first confusion value verification fails.
It should be noted that the device identity in the factory reset request message is consistent with the decrypted device identity, which may mean that the device identity in the factory reset request message is the same as the decrypted device identity. And, the preset algorithm mentioned here is a corresponding decryption algorithm.
In the above scheme, the target terminal decrypts the received first obfuscated value, compares the decrypted device identity with the device identity in the factory reset request message, and determines whether the two are consistent, so as to complete verification of the first obfuscated value.
And S104, executing a factory reset instruction under the condition that the first confusion value is verified.
It should be noted that, when the first confusion value is verified as passing, the target device may send a prompt message to the control terminal to prompt the user corresponding to the control terminal to have no authority to restore the factory settings of the target device. The target device may also send alarm information to a third-party principal (e.g., a special supervision department) to prompt that the third-party principal receives a malicious factory-reset instruction, which may threaten the security of the target device, and the third-party principal may perform tracking processing on the target device according to the alarm information to ensure the security of the target device.
In order to further improve the security of the target device when factory reset is performed, in an embodiment of the present application, the factory reset request message generated by the control terminal further includes a random number. And the first confusion value is obtained by encrypting the factory reset instruction, the equipment identity identifier and the random number by the control terminal based on a preset algorithm and a preset first key.
For example, the factory reset Command is Command, the device ID is ID, and the first key is K1The predetermined algorithm is F1R is the random number, then the first confusion value C1＝F1(K1,Command||ID||R)。
It should be noted that the random number mentioned here may be a number, a letter, a character string obtained by combining a number and a letter, or a character string obtained by combining characters in other forms or different forms, and is not limited in the embodiment of the present application. The random number mentioned here may be randomly generated by the control terminal, or randomly set by the user of the control terminal, and is not limited in the embodiment of the present application.
Through the scheme, the random number is added to the factory setting restoration request message generated by the control terminal, and the random number is also used in the generation process of the first confusion value, so that the problem that after the factory setting restoration request message sent by the control terminal is intercepted by a third party, the third party implements replay attack to obtain the control right of the electronic equipment can be effectively avoided.
When the factory reset request message includes the random number, the method for the target terminal to verify the first obfuscated value is as follows:
encrypting a factory resetting restoration instruction, an equipment identity identifier and a random number in a factory resetting restoration request message based on a preset algorithm and a preset second secret key to obtain a second confusion value;
determining whether the first confusion value and the second confusion value in the factory setting restoration request message are consistent;
determining that the first obfuscated value verifies if the first obfuscated value is identical to the second obfuscated value;
determining that the first obfuscated value fails verification if the first obfuscated value is not consistent with the second obfuscated value.
In addition to the above method, in the embodiment of the present application, the first obfuscated value may be verified by a method shown as follows:
decrypting the first confusion value in the factory setting restoration request message based on a preset algorithm and a preset second key to obtain a corresponding equipment identity and a random number;
determining whether the decrypted equipment identity is consistent with the equipment identity in the factory reset request message; determining whether the random number obtained after decryption is consistent with the random number in the factory reset request message;
in the case where both agree, it is determined that the first obfuscated value verifies.
In some embodiments of the present application, the random number may be a timestamp of the control terminal generating the factory reset request message, that is, the timestamp is used to indicate a time when the control terminal generates the factory reset request message. In the factory reset method provided in this embodiment of the application, in a case where the random number is a timestamp for generating a factory reset request message for the control terminal, before step S103, the method further includes:
determining whether the timestamp exceeds a preset threshold;
and under the condition that the time stamp does not exceed the preset threshold value, determining that the factory reset request message is an effective factory reset request message.
In the above scheme, the random number is set as a timestamp for generating the factory reset request message by the control terminal, and the timestamp is compared with a preset threshold value, so as to determine whether the received factory reset request message is valid, and further avoid a third party from obtaining the control right of the electronic device after intercepting the factory reset request message.
It should be noted that the preset algorithm mentioned in the present application may be an existing encryption algorithm, or may be an algorithm with a data mixing function, which is designed by a manufacturer of the electronic device, and is not limited in the embodiment of the present application.
According to the method for restoring factory settings, the control terminal can add a first confusion value for security verification when sending a factory setting restoring request message to the target device, wherein the first confusion value is obtained by encrypting information such as a factory setting restoring instruction, a device identity mark and the like according to a preset algorithm and a first secret key. The target device can verify the first confusion value through a preset rule after receiving a factory reset request message containing the first confusion value, and can execute a factory reset instruction under the condition that the first confusion value passes the verification. Through the scheme, the problem that electronic equipment in the prior art is not required to be approved by an owner, and other people can restore factory settings of the electronic equipment, so that the electronic equipment is separated from the control of the owner and the owner is lost can be effectively solved. Moreover, the safety of the electronic equipment can be effectively enhanced, and the user experience of the user is improved.
