Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) security, and more specifically, to a method and apparatus for protecting device information, and a computer-readable storage medium. Background Technology

[0002] Currently, the number of IoT smart devices is increasing rapidly. While IoT smart devices can achieve effective communication between devices, automation, and save time and costs, user privacy and security issues still exist. As the number of IoT smart device users grows, manufacturers are focusing on increasing production without giving sufficient attention to security. This makes these smart devices highly vulnerable to attack when hackers discover bugs or security vulnerabilities.

[0003] For example, many IoT companies provide consumers with default credentials, such as administrator usernames, when selling devices. Hackers only need the username and password to attack the device; once they know the username, they can launch a brute-force attack to compromise it. The Mirai botnet attack is an example; the attacked devices all used the default credentials. Consumers should change the default credentials immediately after receiving the device, but most manufacturers do not include this in their user guides. Without updating these user guides, all devices are potentially vulnerable to attack.

[0004] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] Example 1

[0032] According to an embodiment of the present invention, a method embodiment for protecting device information is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 1 This is a flowchart of a device information protection method according to an embodiment of the present invention, such as... Figure 1 As shown, the method for protecting device information includes the following steps:

[0034] Step S102: Send a first instruction to the target device to trigger the target device to detect the first verification information and generate a detection result. The first instruction is used to trigger the target device to detect the first verification information, which is the current default verification information of the target device.

[0035] Optionally, in the above steps, sending the first instruction to the target device can trigger the target device to perform a self-check to check whether its own authentication information, identity credentials, or device account name and password (i.e., the first verification information) are in the current default state.

[0036] Step S104: Obtain the detection result, and if the detection result indicates that the first verification information is the original default verification information, generate and send a second instruction to the target device. The second instruction is used to trigger the target device to modify the first verification information to obtain the second verification information.

[0037] As can be seen from the above, in this embodiment of the invention, a first instruction can first be sent to the target device to trigger the target device to detect the first verification information and generate a detection result. The first instruction is used to trigger the target device to detect the first verification information, which is the target device's current default verification information. Next, the detection result can be obtained, and if the detection result indicates that the first verification information is the original default verification information, a second instruction is generated and sent to the target device. The second instruction is used to trigger the target device to modify the first verification information to obtain the second verification information. Through the device information protection method of this embodiment of the invention, the purpose of sending an instruction that can trigger the target device to perform a self-check to the target device and obtaining the detection result, and then sending an instruction that can trigger the target device to modify its own verification information if the detection result indicates that the target device's credentials are the original default verification information, is achieved. This improves the technical effect of enhancing device security in the Internet of Things and solves the technical problem in related technologies where malicious third parties can easily launch intrusion attacks on devices when they know the device's authentication information.

[0038] As an optional embodiment, before sending the first instruction to the target device, the method for protecting the device information further includes: receiving login information of the target account and verifying the login information to obtain a verification result; if the verification result indicates that the login information has been successfully verified, establishing an association relationship with the target account.

[0039] In the above optional embodiments, before sending the first instruction, the login information of the target account is received, and then the login information is verified. If the verification is successful, the login information is bound to the target account. This allows the user to use the login information of the target account to find the terminal and then control the target device.

[0040] As an optional embodiment, the method for protecting device information further includes: obtaining account information of the target account; sending the account information and terminal device information to the target device, wherein the target device, after receiving the account information and terminal device information, stores the account information and terminal device information in a local storage medium.

[0041] In the above optional embodiments, the account information of the target account is obtained and sent to the target device along with the credential information of the terminal device. After receiving the account information and the credential information of the terminal device, the target device stores them in a local storage medium (e.g., a storage medium such as a hard disk with storage function).

[0042] As an optional embodiment, after sending a second instruction to the target device based on the detection result, the method for protecting the device information further includes: receiving second verification information; and storing the second verification information to a predetermined storage medium.

[0043] Example 2

[0044] According to another aspect of the present invention, a method for protecting device information is also provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0045] Figure 2 This is a flowchart of an optional device information protection method according to an embodiment of the present invention, such as... Figure 2 As shown, the method for protecting device information includes the following steps:

[0046] Step S202: Receive and respond to the first instruction to detect the first verification information and obtain the detection result, wherein the first instruction is an instruction generated by the target terminal and used to trigger the target device to detect the first verification information, and the first verification information is the current default verification information of the target device.

[0047] In the above steps, after receiving the first instruction from the target terminal, the device initiates a self-test of the first verification information and generates a test result.

[0048] Step S204: Send the detection result to the target terminal, wherein the target terminal generates and sends a second instruction if it determines that the first verification information is the original default verification information based on the detection result.

[0049] Step S206: Receive the second instruction.

[0050] In the above steps, the second instruction is sent by the target terminal to trigger the device to dynamically modify the first verification information. The first verification information includes, but is not limited to: the device's own credentials, the device's username and password, and the device's identity verification information.

[0051] Step S208: Based on the second instruction, the first verification information is dynamically modified to obtain the second verification information.

[0052] As can be seen from the above, in this embodiment of the invention, a first instruction can be received and responded to to detect the first verification information and obtain the detection result. The first instruction is generated by the target terminal and used to trigger the target device to detect the first verification information, which is the target device's current default verification information. Then, the detection result is sent to the target terminal. If the target terminal determines that the first verification information is the original default verification information based on the detection result, it generates and sends a second instruction. Then, the second instruction is received. Finally, based on the second instruction, the first verification information is dynamically modified to obtain the second verification information. Through the device information protection method of this embodiment of the invention, the purpose of sending an instruction that can trigger the target device's self-test to the target device and obtaining the detection result is achieved. If the detection result indicates that the target device's credentials are the original default verification information, an instruction that can trigger the target device to modify its own verification information is then sent. This achieves the technical effect of improving device security in the Internet of Things, and solves the technical problem in related technologies where malicious third parties can easily launch intrusion attacks on devices when they know the device's authentication information.

[0053] As an optional implementation, dynamic modification involves dynamically generating second verification information based on the current time and the number of times it has been used as parameters.

[0054] In the above optional embodiments, the method for dynamically modifying the first verification information in the target device is to dynamically and automatically generate the device's username and password based on the continuous changes in time or usage frequency as parameters.

[0055] As an optional embodiment, after obtaining the second verification information, the method for protecting the device information further includes: sending the second verification information to the target terminal, wherein the target terminal stores the second verification information to a predetermined storage medium after receiving the second verification information.

[0056] Figure 3 This is a sequence diagram of user acquisition of dynamic credentials according to an embodiment of the present invention, such as... Figure 3As shown, the user enters their username and password (i.e., the login information of the target account) to log in to the application. This user account is then bound to the application (i.e., the target terminal). Next, network configuration is performed to connect to the IoT device (i.e., the target device). During this process, the application authenticates with the device, transmitting application-related information such as the device ID and the user's account. The device receives this information and stores it in its local data table (i.e., storage medium). The application scans for IoT devices on the network, checking whether the device's default credentials (i.e., the current default verification information) have been modified, specifically whether its password has been changed, or whether the device is in factory reset mode.

[0057] Upon receiving a request to check the default device information, the device queries its own data table to see if the credentials (such as the device username and password) are still in their default state. However, when the device is connected for the first time, the default credentials in the data table (such as the administrator username) are the data initially set by the manufacturer and have not been modified. Therefore, the device will inform the application that the default credentials have not been modified. Upon receiving the device's response indicating no modification (i.e., the detection result), the application determines that the device's default credentials are unchanged. To prevent hackers from knowing the default credentials and using them for intrusion, such as launching a DDoS attack (Distributed Denial of Service attack) that could prevent the device from providing normal service to users, the application will send a request to modify the credentials (i.e., dynamically modify the initial authentication information), allowing the device to modify the credentials automatically.

[0058] After changing the device's username and password (i.e., secondary authentication information), if the user wants to know the device's modified credentials (i.e., secondary authentication information), they will send a message request to the device, which includes authentication information. The device compares the authentication information in the request with the information in its local database. If the authentication information matches, the device will send its modified credentials to the application, and the user will receive new, time-synchronized, dynamic credentials.

[0059] Therefore, in this situation, even if a hacker (i.e., a non-benign third party) knows the current device administrator username, the username and password will change dynamically, so the hacker cannot use the username to launch a brute-force attack to intrude into the device.

[0060] As can be seen from the above, in the embodiments of the present invention, the present invention enables a non-bona fide third party to know the default credentials of the device, such as the administrator username. Since the default credentials are dynamically generated based on time, it is impossible to attack the device based on the existing default credentials, thereby improving the security of IoT devices.

[0061] Example 3

[0062] According to another aspect of the present invention, a device for protecting device information is also provided. Figure 4 This is a schematic diagram of a device for protecting device information according to an embodiment of the present invention, such as... Figure 4 As shown, the device information protection device includes a sending module 41 and an acquisition module 43. The device information protection device will be described below.

[0063] The sending module 41 is used to send a first instruction to the target device to trigger the target device to detect the first verification information and generate a detection result. The first instruction is used to trigger the target device to detect the first verification information, which is the current default verification information of the target device.

[0064] The acquisition module 43 is used to acquire the detection result, and when the detection result indicates that the first verification information is the original default verification information, it generates and sends a second instruction to the target device. The second instruction is used to trigger the target device to modify the first verification information to obtain the second verification information.

[0065] It should be noted that the sending module 41 and the acquiring module 43 mentioned above correspond to steps S102 to S104 in Embodiment 1.

The first instruction is used to trigger the target device to detect the first verification information, which is the target device's current default verification information. Then, the acquisition module 43 acquires the detection result. If the detection result indicates that the first verification information is the original default verification information, a second instruction is generated and sent to the target device. This second instruction triggers the target device to modify the first verification information to obtain the second verification information. Through the device information protection device of this embodiment, the purpose of sending an instruction that can trigger the target device to perform a self-check and acquiring the detection result is achieved. If the detection result indicates that the target device's credentials are the original default verification information, an instruction that can trigger the target device to modify its own verification information is then sent. This achieves the technical effect of improving device security in the Internet of Things, and solves the technical problem in related technologies where malicious third parties can easily launch intrusion attacks on devices when they know the device's authentication information.

[0068] Optionally, the device for protecting device information further includes: an acquisition unit for acquiring account information of the target account; and a sending unit for sending the account information and terminal device information to the target device, wherein the target device stores the account information and terminal device information in a local storage medium after receiving the account information and terminal device information.

[0069] Optionally, the device for protecting the device information further includes: a receiving unit, used to receive second verification information after sending a second instruction to the target device based on the detection result; and a storage unit, used to store the second verification information to a predetermined storage medium.

The first verification information is the current default verification information of the target device.

[0073] The sending module 53 is used to send the detection result to the target terminal, wherein the target terminal generates and sends a second instruction when it determines that the first verification information is the original default verification information based on the detection result.
