Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a data processing method, apparatus, device, and storage medium. Background Technology

[0002] With the development of modern information, communication, computer, and control technologies, different devices can communicate, work collaboratively, and share resources, forming a device interconnection system. This system contains multiple electronic devices that can communicate with each other, including servers. In some cases, users can control other electronic devices within the device interconnection system through the server.

[0003] In interconnected device systems, information from each electronic device is typically stored using an encryption algorithm, either individually on the device itself or centrally encrypted on a server. When device information is stored separately on each device, decrypting each device allows access to its information; when stored on a server, decrypting the server allows access to the device information of all devices in the entire interconnected system. While interconnected device systems offer convenience and efficiency, they also pose significant risks to data security and user privacy. Summary of the Invention

Further, if a target number of times is less than a preset threshold, the server sends a fourth storage message to a fifth storage device, causing the fifth storage device to respond to the storage instruction, store the fourth data, and send a fifth storage message to the server; the fifth storage message includes a storage instruction and fifth data; the fifth data is data stored in the fifth storage device; the target number of times is the number of storage instructions received by the server; if the target number of times is equal to the preset threshold, the server responds to the storage instruction and stores the fourth data.

[0036] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0037] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0038] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" and "multiple" refer to two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0039] In existing technologies, information from various electronic devices in interconnected systems is typically stored using some form of encryption algorithm on each device or centrally encrypted on a server. This means that if an attacker wants to access the data stored on a particular electronic device, they can simply decrypt that device or server, posing a significant threat to data security and user privacy.

[0040] To address the aforementioned problems, this application provides a data processing method, apparatus, device, and storage medium. The data processing method is applied to a second storage device, which is not the first storage device among multiple storage devices to execute a data storage task. The multiple storage devices are used to execute the data storage task. The data processing method includes: the second storage device receiving a first storage message sent by a first storage device among the multiple storage devices; the first storage message includes a storage instruction, a task execution order of the first storage device, and first data, where the first data is data in the first storage device, and the task execution order is the order in which the storage devices execute the data storage task. Further, if the task execution order of the second storage device is less than a preset threshold, the second storage device, in response to the storage instruction, stores the first data and sends a second storage message to a third storage device among the multiple storage devices; the second storage message includes a storage instruction, the task execution order of the second storage device, and second data, where the second data is data in the second storage device. If the task execution order of the second storage device is equal to the preset threshold, the second storage device sends a second storage message to a server, causing the server, in response to the storage instruction, to store the second data.

[0041] In the data processing method provided in this application, the first data of the first storage device in a plurality of storage devices is stored in the second storage device, the second data of the second storage device is stored in the third storage device, and so on, until the last storage device in the plurality of storage devices, which sends part or all of its stored data to the server for storage. In this way, the data stored in each storage device is incomplete, and a codebreaker cannot obtain the complete data of the current device by only deciphering the current device.

[0042] Figure 1A communication system is illustrated, and the data processing method provided in the embodiments of this application can be applied to, for example, Figure 1 The communication system 10 shown is used to protect the security of the stored information of electronic devices, preventing the hacker from obtaining all the data of the electronic device after it has been deciphered. Figure 1 As shown, the communication system 10 includes storage device A11, storage device B12, storage device C13, storage device D14, and server 15.

[0043] Among them, storage devices A11, B12, C13, and D14 are used to represent different storage devices. These storage devices can be of the same model or different models of electronic devices with storage capabilities. Additionally, Figure 1 The example shows four storage devices, which does not constitute a limitation on the number of storage devices.

[0044] It needs to be explained that, Figure 1 The communication system 10 shown can be a multi-device interconnection system such as a smart grid, communication base station, and smart home, and the storage device is an electronic device with storage function within the interconnection system.

[0045] To protect the security of stored information on each storage device, the data processing method provided in this application can be applied to storage devices that are not the first to perform a data storage task. The data storage task involves a storage device sending local data to other storage devices for storage. For example, if the storage devices perform the data storage task in the order of storage device A11, storage device B12, storage device C13, and storage device D14, then the data processing method provided in this application can be applied to any one of storage devices B12, C13, or D14.

[0046] Figure 2 This is a flowchart illustrating a data processing method according to some exemplary embodiments. In some embodiments, the above-described data processing method can be applied to, for example... Figure 1 The communication system 10 shown is a storage device that is not the first to perform a data storage task. Hereinafter, this application embodiment uses the application of the data processing method to a second storage device as an example, where the second storage device is not the first among multiple storage devices to perform a data storage task, to describe the aforementioned data processing method.

[0047] like Figure 2 As shown, the data processing method provided in this application embodiment includes the following S201-S205.

[0048] S201, the second storage device receives a first storage message sent by the first storage device among a plurality of storage devices.

[0049] The first storage message includes a storage instruction, a task execution order of the first storage device, and first data. The first data is the data in the first storage device, and the task execution order is the order in which the storage device executes data storage tasks.

[0050] As one possible implementation, if the first storage device is the first storage device to perform the data storage task, the first storage device responds to the storage instruction to perform the data storage task sent by the server, or responds to the storage instruction to perform the data storage task directly generated by the user on the first storage device, determines part or all of the data from the stored data as the first data, generates a first storage message, and sends it to the second storage device.

[0051] Accordingly, the second storage device receives the first storage message sent by the first storage device and obtains the storage instruction, the task execution order of the first storage device, and the first data.

[0052] It should be noted that, in the case where the first storage device is the first storage device to perform the data storage task, the first storage device can be any one of multiple storage devices.

[0053] For example, if the first storage device is Figure 1 In the communication system 10 shown, storage device A11 is the first storage device, and storage device B12 is the second storage device. Storage device A11 receives a storage instruction from the user via server 15 or by directly operating storage device A11 to execute a data storage task. In response to the storage instruction, storage device A11 determines itself as the first storage device to execute the data storage task, that is, the task execution order of storage device A11 is 1. Further, storage device A11 determines the first data from the locally stored data and sends the first data, the storage instruction, and the task execution order of storage device A11 in a first storage message to storage device B12.

[0054] As another possible implementation, if the first storage device is not the first storage device to execute the data storage task, the first storage device, in response to a storage instruction received from the previous storage device, identifies some or all of the stored data as the first data, and determines the task execution order of the first storage device based on the task execution order of the previous storage device. Further, the first data, the storage instruction, and the task execution order of the first storage device are carried in a first storage message and sent to the second storage device.

[0055] Accordingly, the second storage device receives the first storage message sent by the first storage device and obtains the storage instruction, the task execution order of the first storage device, and the first data.

[0056] For example, if the first storage device is Figure 1 In the communication system 10 shown, storage device B12 is the first storage device, and storage device C13 is the second storage device. Storage device B12 determines its own task execution order as 2 based on the storage instruction previously sent by storage device A11 and the task execution order 1 of storage device A11, and determines the first data from its locally stored data. Further, it sends the first data, the storage instruction, and the task execution order 2 of storage device B12, along with a first storage message, to storage device C13.

[0057] It should be noted that each of the multiple storage devices stores multiple data segments at different addresses. Therefore, the first data in the first storage message includes at least one of the multiple data segments at different addresses in the first storage device.

[0058] When the first storage device determines the first data, it can determine the data segment included in the first data among multiple data segments at different addresses according to a preset probability.

[0059] For example, the first storage device includes data segments A, B, C, D, and E. If the first storage device selects data segments A and D according to a preset probability, then the first data includes data segment A and data segment D.

[0060] S202, the second storage device determines the task execution order of the second storage device based on the task execution order of the first storage device.

[0061] As one possible implementation, after determining the task execution order of the first storage device from the first storage message sent from the first storage device, the second storage device obtains the task execution order of the second storage device by incrementing the task execution order of the first storage device by one.

[0062] It should be noted that since the first storage device sends the storage instruction used to instruct the execution of the data storage task to the second storage device, that is, the second storage device is the next storage device to execute the data storage task of the first storage device, the task execution order of the first storage device plus one is the task execution order of the second storage device.

[0063] S203. If the task execution order of the second storage device is less than a preset threshold, the second storage device responds to the storage instruction and stores the first data.

[0064] The preset threshold can be the number of multiple storage devices, or it can be a value less than the number of multiple storage devices. This application embodiment does not specifically limit this.

[0065] As one possible implementation, the second storage device determines the relationship between the task execution order of the second storage device and a preset threshold. If the task execution order of the second storage device is less than the preset threshold, the second storage device stores the first data carried in the first storage message.

[0066] S204. After storing the first data, the second storage device sends a second storage message to the third storage device among the multiple storage devices.

[0067] The second storage message includes a storage instruction, a task execution sequence of the second storage device, and second data, where the second data is the data in the second storage device.

[0068] As one possible implementation, after storing the first data, the second storage device determines the second data from the data stored locally other than the first data, and sends the second data, storage instructions, and the task execution order of the second storage device in a second storage message to the third storage device.

[0069] It should be noted that the third storage device is any one of the multiple storage devices that has not yet performed data processing tasks.

[0070] For example, if the second storage device is as described above Figure 1 In the communication system 10 shown, storage device B12 and storage device A11 are the first storage devices that perform data processing tasks before storage device B12. After generating the second storage message, storage device B12 can select any one of storage devices C13 and D14 as the third storage device and send the second storage message to it so that the third storage device can perform data processing tasks.

[0071] In some embodiments, the second storage message further includes a replacement identifier, which is used to indicate whether the second data in the second storage message is empty.

[0072] It should be noted that the second storage device adds a replacement identifier to the flag bit of the generated second storage message, so that the storage device receiving the second storage message can determine whether the second data carried in the second storage message is empty based on the replacement identifier, that is, determine whether the second storage message carries second data for replacement storage.

[0073] For example, in the 10th bit of the generated second storage message, the second storage device uses a binary character "1" to indicate that the second data is not empty, and a binary character "0" to indicate that the second data is empty. The storage device receiving the second storage message can determine whether the second storage information carries the second data by checking the replacement identifier in the 10th bit. If the replacement identifier in the 10th bit is "1", the second data is stored locally. If the replacement identifier in the 10th bit is "0", the same process is performed to store empty data locally.

[0074] S205. If the task execution order of the second storage device is equal to a preset threshold, the second storage device sends a second storage message to the server.

[0075] As one possible implementation, if the second storage device determines that its task execution order is equal to a preset threshold, it indicates that it is the last storage device among multiple storage devices to execute the data storage task. Therefore, it sends a second storage message to the server so that the server responds to the storage instruction and stores the second data.

[0076] In some embodiments, after performing data storage tasks, each storage device encrypts the storage space using its own internally recorded encryption algorithm. As a result, multiple encryption algorithms exist in multiple storage devices, increasing the difficulty for decryptors to crack the storage devices.

[0077] Understandably, in the data processing method provided in this application, the first data of the first storage device in a plurality of storage devices is stored in the second storage device, the second data of the second storage device is stored in the third storage device, and so on, until the last storage device in the plurality of storage devices, which sends part or all of its stored data to the server for storage. In this way, the data stored in each storage device is incomplete, and a codebreaker cannot obtain the complete data of the current device by only deciphering the current device.

[0078] In one design, to enable maintenance personnel of the device interconnection system to retrieve data stored in a storage device normally, the data processing method provided in this application includes a first storage message that further comprises a device identifier of the first storage device and a first data address, wherein the first data address is the storage address of the first data in the first storage device. If the task execution order of the second storage device is less than a preset threshold, such as... Figure 3 As shown, the data processing method provided in this application embodiment also includes S301-S303.

[0079] S301, the second storage device receives the first recovery message sent by the third storage device.

[0080] The first recovery message includes a recovery instruction, second data, and a second data address; the second data address is the storage address of the second data in the second storage device.

[0081] In one possible implementation, in response to a recovery instruction sent by the previous storage device during the recovery process, the third storage device determines the target to which the first recovery message is to be sent from the device identifier of the internally stored second storage device. Further, the third storage device sends the received recovery instruction, along with the internally stored second data and its address, in the first recovery message to the second storage device.

[0082] Accordingly, the second storage device receives the first recovery message sent by the third storage device and obtains the recovery instruction, the second data, and the second data address.

[0083] It should be noted that the device identifier and the second data address of the second storage device are stored in the third storage device after the third storage device receives the second storage message.

[0084] In cases where the second data comprises multiple data segments with different addresses, the second data address includes a storage address used to indicate the storage address of each data segment in the second storage device.

[0085] S302, the second storage device responds to the recovery instruction and recovers the data of the second storage device according to the second data address and the second data.

[0086] As one possible implementation, after receiving the first recovery message, the second storage device responds to the recovery instruction in the first recovery message and stores the second data in the second storage device based on the second data address, so as to ensure that the second storage device stores complete data for operation and maintenance personnel to retrieve.

[0087] S303, the second storage device sends a second recovery message to the first storage device based on the device identifier of the first storage device.

[0088] The second recovery message includes a recovery instruction, first data, and a first data address. The device identifier and the first data address of the first storage device are stored by the second storage device after receiving the first storage message.

[0089] As one possible implementation, the second storage device queries the device identifier of the first storage device from its internal storage space to determine the recipient of the second recovery message. Further, the second storage device sends the received recovery instruction, along with the first data and the first data address stored internally, in the first recovery message to the first storage device. This allows the first storage device, upon receiving the first recovery message, to respond to the recovery instruction and recover the data in its own storage device based on the first data and the first data address.

[0090] Understandably, the data processing method provided in this application restores the stored data of multiple storage devices, except for the last storage device that performs the data storage task, so that maintenance personnel can retrieve the data normally when they need to use the data in the storage device.

[0091] In one design, to enable maintenance personnel of the device interconnection system to retrieve data stored in the storage device normally, the data processing method provided in this application includes a second storage message that further comprises a device identifier of the second storage device and a second data address, wherein the second data address is the storage address of the second data in the second storage device. When the task execution order of the second storage device equals a preset threshold, such as... Figure 4 As shown, the data processing method provided in this application embodiment also includes S401-S403.

[0092] S401, The second storage device receives the third recovery message sent by the server.

[0093] The third recovery message includes a recovery instruction, second data, and a second data address; the second data address is the storage address of the second data in the second storage device, and the device identifier of the second storage device and the second data address are stored by the server after receiving the second storage message.

[0094] In one possible implementation, in response to a recovery instruction issued by the operations and maintenance personnel, the server determines the recipient of the third recovery message from the device identifier of the internally stored second storage device. Further, the server includes the received recovery instruction, along with the internally stored second data and its address, in a first recovery message and sends it to the second storage device.

[0095] Correspondingly, the second storage device receives the first recovery message sent by the server and obtains the recovery instruction, the second data, and the second data address.

[0096] It should be noted that when the second data includes multiple data segments with different addresses, the second data address includes the storage address used to indicate the storage address of each data segment in the second storage device.

[0097] S402, the second storage device responds to the recovery instruction and recovers the data of the second storage device according to the second data address and the second data.

[0098] It should be noted that the specific implementation of step S402 can be referred to the implementation of step S302 in the above embodiments of this application, and will not be repeated here.

[0099] S403, the second storage device sends a second recovery message to the first storage device based on the device identifier of the first storage device.

[0100] The second recovery message includes a recovery instruction, first data, and a first data address. The device identifier and the first data address of the first storage device are stored by the second storage device after receiving the first storage message.

[0101] It should be noted that the specific implementation of step S403 can be referred to the implementation of step S303 in the above embodiments of this application, and will not be repeated here.

[0102] It is understood that the data processing method provided in this application embodiment restores the stored data of the last storage device that performs the data storage task among multiple storage devices, so that maintenance personnel can retrieve the data normally when they need to use the data in the storage device.

[0103] In one design, Figure 5 This is a flowchart illustrating a data processing method according to some exemplary embodiments. In some embodiments, the above-described data processing method can be applied to, for example... Figure 1 The communication system 10 shown includes a server 15. Hereinafter, embodiments of this application will describe the data processing method using an example of the data processing method applied to a server.

[0104] like Figure 5 As shown, the data processing method provided in this application embodiment includes the following S501-S505.

[0105] S501, The server receives the fourth storage message sent by the fourth storage device.

[0106] The fourth storage message includes a storage instruction and fourth data; the fourth data is the data in the fourth storage device.

[0107] As one possible implementation, the fourth storage device responds to a storage instruction generated directly on the fourth storage device by the user to perform a data storage task, determines some or all of the stored data as the fourth data, generates a first storage message, and sends it to the server.

[0108] Correspondingly, the server receives the fourth storage message sent by the fourth storage device.

[0109] For example, if the fourth storage device is Figure 1 The communication system 10 shown includes a storage device A11. Storage device A11 determines the storage instruction generated by the user to perform a data storage task, and in response to the storage instruction, storage device A11 determines the fourth data from locally stored data, and sends the fourth data and the storage instruction along with a first storage message to the server.

[0110] It should be noted that each of the multiple storage devices stores multiple data segments at different addresses. Therefore, the first data in the first storage message includes at least one of the multiple data segments at different addresses in the first storage device.

[0111] When determining the fourth data in the fourth storage device, the data segment included in the fourth data can be determined from multiple data segments at different addresses according to a preset probability.

[0112] For example, the fourth storage device includes data segments A, B, C, D, and E. If the fourth storage device selects data segments A and D according to a preset probability, then the fourth data includes data segment A and data segment D.

[0113] S502, The server determines the target number of times.

[0114] The target number is the number of times the server receives storage instructions.

[0115] As one possible implementation, after the server obtains the storage instruction sent by the fourth storage device from the fourth storage message, the counter in the server used to calculate the number of times the storage instruction has been received is incremented by one to obtain the number of times the server has received the storage instruction, i.e., the target number.

[0116] It should be noted that since storage devices send storage instructions to the server after performing data storage tasks, the number of storage instructions received by the server can represent the number of storage devices that have performed data storage tasks.

[0117] S503. If the target number of times is less than the preset threshold, the server sends a fourth storage message to the fifth storage device.

[0118] The preset threshold can be the number of multiple storage devices, or it can be a value less than the number of multiple storage devices. This application embodiment does not specifically limit this.

[0119] As one possible implementation, the server determines the size relationship between the target number and the preset threshold. If the target number is less than the preset threshold, the server forwards the fourth storage message to the fifth storage device, so that the fifth storage device responds to the storage instruction in the fourth storage message, stores the fourth data, and sends the fifth storage message to the server.

[0120] It should be noted that the fifth storage message includes a storage instruction and fifth data; the fifth data is the data in the fifth storage device; the target number is the number of storage instructions received by the server.

[0121] S504. When the target number of times equals the preset threshold, the server responds to the storage instruction and stores the fourth data.

[0122] As one possible implementation, if the server determines that the target number of times for the fourth storage device equals a preset threshold, it designates the fourth storage device as the last storage device among multiple storage devices to perform the data storage task. Furthermore, in response to the storage instruction, the server stores the fourth data.

[0123] Understandably, in the data processing method provided in this application, the first data of the first storage device in a plurality of storage devices is stored in the second storage device, the second data of the second storage device is stored in the third storage device, and so on, until the last storage device in the plurality of storage devices, which sends part or all of its stored data to the server for storage. In this way, the data stored in each storage device is incomplete, and a codebreaker cannot obtain the complete data of the current device by only deciphering the current device.

[0124] In one design, to enable maintenance personnel of the device interconnection system to retrieve data stored in the storage device normally, the data processing method provided in this application further includes a fourth storage message containing a device identifier of the fourth storage device and a fourth data address, where the fourth data address is the storage address of the fourth data in the fourth storage device. For example... Figure 6 As shown, the data processing method provided in this application embodiment also includes S601-S602.

[0125] S601, The server receives the fourth recovery message sent by the fifth storage device.

[0126] The fourth recovery message includes a recovery instruction, a device identifier of the fourth storage device, fourth data, and a fourth data address; the device identifier and the fourth data address of the fourth storage device are stored by the fifth storage device after receiving the fourth storage message.

[0127] In one possible implementation, in response to a recovery instruction sent by the server, the fifth storage device sends the received recovery instruction, along with the fourth data and its address stored internally, in a fourth recovery message to the server.

[0128] Correspondingly, the server receives the fourth recovery message sent by the fifth storage device. It then obtains the recovery instruction, the fourth data, and the address of the fourth data.

[0129] S602. In response to the recovery instruction, the server sends a fourth recovery message to the fourth storage device based on the device identifier of the fourth storage device.

[0130] In one possible implementation, the server responds to the recovery instruction in the fourth recovery message, identifies the fourth storage device based on the device identifier of the fourth storage device, and forwards the fourth recovery message to the fourth storage device, so that the fourth storage device responds to the recovery instruction, recovers the data of the fourth storage device based on the fourth data address and the fourth data, and sends a fifth recovery message to the server if the sixth data is stored in the fourth storage device.

[0131] It should be noted that the fifth recovery message includes a recovery instruction, the device identifier of the sixth storage device, the sixth data, and the sixth data address. The sixth data is the data in the sixth storage device, and the sixth data address is the storage address of the sixth data in the sixth storage device.

[0132] Understandably, the data processing method provided in this application restores the stored data in multiple storage devices, so that maintenance personnel can retrieve the data normally when they need to use the data in the storage devices.

[0133] In the data processing method provided in this application, the first data of the first storage device in a plurality of storage devices is stored in the second storage device, the second data of the second storage device is stored in the third storage device, and so on, until the last storage device in the plurality of storage devices, which sends part or all of its stored data to the server for storage. In this way, the data stored in each storage device is incomplete, and a codebreaker cannot obtain the complete data of the current device by only deciphering the current device.
