[0041] Figure 1The system 100 can be configured and operated in various ways to enable the application of the various methods and apparatus described in this disclosure.

[0042] Figure 2 A flowchart of a data transmission method 200 according to an exemplary embodiment of the present disclosure is shown. Figure 2 As shown, method 200 includes:

[0043] Step S201: Obtain the raw data to be sent, wherein the raw data includes multiple raw keys and the value corresponding to each of the multiple raw keys;

[0044] Step S202: Obtain encoding information for the original data, the encoding information including order information for the plurality of original keys, wherein the order information includes the permutation number of each of the plurality of original keys in a random sequence composed of the plurality of original keys;

[0045] Step S203: Based on the order information, determine the sequence consisting of the values ​​corresponding to each of the plurality of original keys to obtain the target data; and

[0046] Step S204: Send the target data to the data receiving device so that the data receiving device can determine the original data based on the decoding information and the target data, wherein the decoding information includes the plurality of original keys and the order information.

[0047] By arranging multiple values ​​in the original key-value pair data based on random key order information, target data consisting of multiple randomly disordered values ​​can be obtained and sent. In this case, only the data receiving device can reconstruct the original key-value pair data based on the decoded information containing the original keys and key order information. It is impossible to directly reconstruct the complete original data from the transmitted target data, which reduces the risk of original data leakage and improves the security of data transmission.

[0048] In some examples, the original data can be data containing multiple key-value pairs, such as JSON data.

[0049] In some examples, the encoded and decoded information can be generated using encoding tools that incorporate random algorithms. For instance, this can be achieved by randomly permuting multiple raw keys to obtain a random sequence of raw keys, and then recording the permutation number of each raw key to obtain the encoding and decoding tables. By storing the encoded and decoded information separately at the data sender and receiver, security can be improved, and the risk of the target data being cracked and leaked can be reduced.

[0050] In some examples, the encoded and decoded information can be determined using algorithms deployed on the data sender and receiver respectively, which implement specific random mapping rules. Thus, the encoded and decoded information can be obtained by executing the random mapping algorithm, as long as the order information applied by the data sender and receiver is consistent. This avoids storing plaintext encoding and decoding information and further enhances security.

[0051] According to some embodiments, the original data formats of the values ​​corresponding to each of the plurality of original keys are not all the same. Determining the sequence of values ​​corresponding to each of the plurality of original keys based on the order information to obtain target data includes: converting the value corresponding to each of the plurality of original keys into a data item with a preset data format; and concatenating the data items corresponding to each of the plurality of original keys based on the order information to obtain the target data. The decoding information further includes data format information indicating the original data format of the values ​​corresponding to each of the plurality of original keys, so that the data receiving device can determine the corresponding value of each data item based on the data format information. Therefore, the values ​​in the original data can be converted into data items with a preset data format, avoiding the exposure of plaintext data and further improving the security of data transmission.

[0052] In some examples, each plaintext value can be converted into a binary data item of fixed byte length, and the corresponding data items of multiple values ​​can be concatenated into a binary sequence to improve the efficiency and security of data transmission. Furthermore, in some examples, compression encryption algorithms can be applied to compress and encrypt the original binary sequence data to output compressed and encrypted binary data. For example, data can be compressed using a compression algorithm, and during the compression process, a digest algorithm can be used to calculate the digest information, while simultaneously using a symmetric encryption algorithm to encrypt the data. A random symmetric encryption key can be generated and encrypted using the public key of an asymmetric encryption algorithm. The final output is compressed binary data integrating the encryption algorithms, effectively improving the efficiency and security of data transmission.

[0053] In this situation, when the original data formats of the values ​​in the original data are not all the same, it is necessary to further restore the target data to the original data based on the data format information. In this case, encoding tools can be used to generate encoding and decoding information containing order information and data format information based on the data format description file of the original data, so that the data receiver can restore the original data based on the data format information, thereby further improving the security of data transmission.

[0054] In some examples, the original data format of the values ​​corresponding to multiple original keys in the original data can include integer, floating-point, string, boolean, etc.

[0055] In the example above, the binary sequence data contained in the target data is composed of multiple data items corresponding to multiple values. Understandably, these multiple data items need to have the same preset length to achieve data format alignment between the data sender and receiver. However, the following possibility exists: the lengths of the values ​​in the original data are not all the same. When the length of the value in the original data is less than the preset length of the data item, it will cause redundancy in the size of the target data, affecting data transmission efficiency. Furthermore, the security of target data composed of multiple fixed-length data items is insufficient.

[0056] Based on this, according to some embodiments, when the lengths of the values ​​corresponding to each of the plurality of original keys are not all the same, the step of converting the value corresponding to each of the plurality of original keys into a data item with a preset data format includes: for each of the plurality of original keys, determining a first sub-element based on the length of the value corresponding to the original key; determining a second sub-element based on the value corresponding to the original key; and determining the data item corresponding to the original key based on the first sub-element and the second sub-element. Thus, even when the original lengths of the original data values ​​are not all the same, the first sub-element can be used to indicate the length of each value, and second sub-elements with different lengths can be used to represent the data content of each value. This forces the data receiving device to read the second sub-element based on the length information indicated by the first sub-element, improving the efficiency and security of data transmission.

[0057] In some examples, the first sub-element can be determined based on bit identifiers to indicate the byte length of the data item corresponding to each value.

[0058] According to some embodiments, the encoded information further includes an identifier corresponding to each of the plurality of original keys. The value in the original data is modified using the following process: in response to receiving a data modification request for a target identifier, a target original key corresponding to the target identifier is determined based on the encoded information; and the value corresponding to the target original key is modified based on the data modification request. Therefore, a data modification entry point containing only the identifier corresponding to the original key can be set up at the data sender. By modifying the value of the original data through the identifier, the plaintext information of the original key can be avoided, thus improving data security.

[0059] According to some embodiments, the encoded information further includes at least one virtual key, and the order information includes the permutation number of each of the plurality of original keys in a random sequence composed of the plurality of original keys and at least one virtual key. The method further includes: randomly generating a value corresponding to each of the at least one virtual key, and wherein determining the sequence composed of the values ​​corresponding to each of the plurality of original keys to obtain target data based on the order information includes: determining the sequence composed of the values ​​corresponding to each of the plurality of original keys and the values ​​corresponding to each of the at least one virtual key to obtain the target data based on the order information. Therefore, by inserting virtual invalid data into the original data, the complexity of the target data can be increased, original data leakage can be avoided, and security can be further improved.

[0060] In some examples, for multiple original keys, a random algorithm is first used to generate a random ordinal number corresponding to each original key. When the multiple random ordinal numbers corresponding to multiple original keys cannot form a continuous natural number sequence, a dummy key can be used to fill the blank ordinal numbers in the natural number sequence to obtain a sequence consisting of multiple original keys and at least one dummy key.

[0061] For example, when the original data contains four real original keys A, B, C, and D, a random algorithm can be used to generate a random ordinal number corresponding to each original key. When the random ordinal numbers corresponding to the four original keys A, B, C, and D are 5, 3, 7, and 2 respectively, virtual keys e, f, and g can be filled into the blank ordinal numbers 1, 4, and 6 in the natural number sequence 1-7 respectively, so as to obtain a sequence composed of e, D, B, f, A, g, and C. Based on this, encoding and decoding information is generated, and virtual value data corresponding to the virtual keys is inserted into the target data, which increases the complexity of the encoding and decoding information and the target data, and improves the security of data transmission.

[0062] According to some embodiments, the encoded information and the decoded information are updated synchronously according to a preset time period. This allows for the synchronous updating of encoded and decoded information according to a preset period, ensuring consistency between the encoded and decoded information on both sides and improving the security of data transmission.

[0063] According to one aspect of this disclosure, a data receiving method is also provided. Figure 3 A flowchart of a data receiving method 300 according to an exemplary embodiment of the present disclosure is shown. Figure 3 As shown, method 300 includes:

[0064] Step S301: Receive target data, wherein the target data includes multiple values ​​arranged in sequence;

[0065] Step S302: Obtain decoding information for the target data, wherein the decoding information includes multiple raw keys and order information for the multiple raw keys;

[0066] Step S303: Based on the ordinal numbers of the multiple values ​​in the sequence composed of the multiple values ​​and the order information, determine the one-to-one mapping relationship between the multiple values ​​and the multiple original keys; and

[0067] Step S304: Based on the one-to-one mapping relationship between the plurality of values ​​and the plurality of original keys, determine the original data corresponding to the target data. The original data includes the plurality of original keys and the value corresponding to each of the plurality of original keys.

[0068] After receiving multiple values ​​arranged in sequence, the data receiving device must reconstruct the original data containing multiple key-value pairs based on the decoded information containing the original key and key order information. It cannot directly reconstruct the complete original data from the transmitted target data, which can reduce the risk of leakage of the original data and improve the security of data transmission.

[0069] According to some embodiments, each of the plurality of values ​​is represented using a data item with a preset data format. The decoding information further includes data format information, which indicates the original data format of the value corresponding to each of the plurality of original keys. Furthermore, determining the original data corresponding to the target data based on the one-to-one mapping relationship between the plurality of values ​​and the plurality of original keys includes: for each of the plurality of original keys, converting the data item corresponding to the preset data format of that original key into the original data format to obtain the original data. Therefore, when the value in the target data is represented in the form of data items, the data receiving device needs to further restore the data items in the target data to the values ​​in the original data based on the data format information, further improving the security of data transmission.

[0070] According to some embodiments, the data item includes a first sub-element representing the length of the value corresponding to the data item and a second sub-element representing the value corresponding to the data item. The step of converting a data item with a preset data format corresponding to each of the plurality of original keys into an original data format includes: determining a first length of the value corresponding to the data item based on the first sub-element; determining a second length of the second sub-element based on the first length; reading the second sub-element based on the second length; and converting the second sub-element into the original data format. Therefore, when the original lengths of the values ​​in the original data are not all the same, multiple values ​​can be represented using data items of different lengths. The data receiving device must read the second sub-element from the concatenated target data based on the length information indicated by the first sub-element, and parse the corresponding value of each data item accordingly, further improving the security of data transmission.

[0071] In one example, the raw data could be JSON data like this: {"name":"xiaoming","age":21,"weight":60}. Based on this, the corresponding raw data format description information can be determined as: {"name":"string","age":"int","weight":"int"}. Understandably, the raw data format can use a more readable string as an identifier, or it can use an integer as an identifier, as long as it can be used to distinguish the data type.

[0072] Based on this, the identifiers corresponding to the multiple original keys shown in Table 1 and the order information of the multiple original keys shown in Table 2 can be randomly generated.

[0073] Table 1:

[0074] name 3 age 1 weight 2

[0075] Table 2:

[0076] name 2 age 3 weight 1

[0077] Based on the above identifier and order information, the encoding table shown in Table 3 and the decoding table shown in Table 4 can be generated.

[0078] Table 3:

[0079] 3 2 1 3 2 1

[0080] Table 4:

[0081] 1 weight int 2 name string 3 age int

[0082] In some examples, the encoding table can use data structures such as multi-level linked lists, multi-level HashMaps, and trees to store data. The decoding table can use a multi-level linked list data structure to store data.

[0083] In some examples, the data receiver can store the mapping relationship between the above multiple identifiers and the original keys of the plaintext at the same time. When the original data is input or modified, the mapping relationship can be removed to avoid exposing the original key information of the plaintext during data transmission.

[0084] According to one aspect of this disclosure, a data transmission apparatus is also provided. Figure 4 A structural block diagram of a data transmission apparatus 400 according to an exemplary embodiment of the present disclosure is shown. Figure 4 As shown, the device 400 includes:
