[0029] Embodiment 1

[0030] Figure 1 A flowchart of a data encryption and decryption transmission method is provided for the first embodiment of the present invention. This embodiment can be applied to encrypt the target transmission data by a preset data encryption algorithm, and transmit the encrypted data to a second terminal, so that the second terminal decrypts the target encrypted data by a preset data decryption algorithm to obtain the target transmission data. The method can be executed by a data encryption and decryption transmission device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0031] S110: Acquire target transmission data of the first terminal, and determine an initial data frame set corresponding to the target transmission data based on a pre-constructed data frame construction algorithm.

[0032] The first terminal may be an embedded device in the power Internet of Things, such as a smart meter. The first terminal may be used to monitor and collect power data in the power Internet of Things in real time, and process and encrypt the collected power data. The power data may include voltage data, current data, and the collection time of voltage and current data.

[0033] The target transmission data may be target transmission data corresponding to the power data obtained by cleaning, denoising, and normalizing the collected power data through the first terminal.

[0034] The data frame construction algorithm may be a pre-constructed algorithm for encapsulating the target transmission data to be transmitted into a data frame according to a preset data format and a preset processing rule in network communication. The initial data frame set may be a set of multiple data frames into which the target transmission data of the first terminal is encapsulated by the data frame construction algorithm.

[0035] Optionally, before acquiring the target transmission data of the first terminal, the method may further include: acquiring target power data, and preprocessing the target power data through a normalization algorithm to obtain the target transmission data of the first terminal.

[0036] The target power data may be data related to power obtained through the first terminal in the power system. The target power data may be collected from various links such as power production, transmission, distribution, and power supply load, and is used to reflect the operating status, load conditions, energy efficiency, and other information of the power system. The target power data may include current data and voltage data. The normalization algorithm may be a minimum-maximum normalization algorithm.

[0037] Exemplarily, the target power data can be preprocessed by a normalization algorithm to obtain the target transmission data of the first terminal by the following formula:

[0038] Voltage data:

[0039]

[0040] Among them, X 1 is the normalized value of voltage data, X V is the original value of voltage data, X Vmax Indicates the maximum value of voltage data, X vmin Indicates the minimum value of voltage data;

[0041] Current data:

[0042]

[0043] Among them, X 2 is the normalized value of the current data, X A is the original value of current data, X Amax Indicates the maximum current data, X Amin Indicates the minimum value of current data.

[0044] Optionally, an initial data frame set corresponding to the target transmission data is determined based on a pre-constructed data frame construction algorithm, including: processing the target transmission data through the data frame construction algorithm to obtain a binary sequence data frame corresponding to the target transmission data; dividing the binary sequence data frame into multiple data subsequences according to a preset grouping length, and determining an initial data frame set corresponding to the target transmission data based on the multiple data subsequences.

[0045] The data frame construction algorithm may be a pre-constructed algorithm for converting and encapsulating the target transmission data into a data frame. The binary sequence data frame may be a sequence in binary form corresponding to the target transmission data obtained after being processed by the data frame construction algorithm and encapsulated into a data frame. The preset packet length may be a pre-set length of each data subsequence. The data subsequence may be a binary sequence data frame divided into a plurality of fixed-length data units according to the preset packet length by the data frame construction algorithm, and each data subsequence contains a portion of the original data.

[0046] Specifically, the target transmission data can be converted into a binary sequence data frame based on a pre-constructed data frame construction algorithm, and divided into multiple data subsequences according to a preset group length, and then the initial data frame set corresponding to the target transmission data is determined, which can further improve the efficiency of processing and transmission of power data.

[0047] S120. Determine an encrypted data sequence corresponding to the initial data frame set based on a preset data encryption algorithm, and determine target encrypted data corresponding to the target transmission data according to the initial data frame set and the encrypted data sequence.

[0048] The preset data encryption algorithm may be a predefined algorithm for encrypting data. The preset data encryption algorithm may encrypt each data subsequence in the initial data frame set to ensure the security of the data during transmission. The encrypted data sequence may be an encrypted data sequence obtained after encrypting multiple data subsequences corresponding to the initial data frame set by the preset data encryption algorithm. The target encrypted data may be encrypted data determined according to the initial data frame set and the encrypted data sequence and used to be sent to the data recipient.

[0049] Optionally, determining an encrypted data sequence corresponding to an initial data frame set based on a preset data encryption algorithm includes: obtaining a preset binary sequence, performing a cyclic shift process on each data subsequence through a preset data encryption algorithm to obtain a shifted subsequence corresponding to each data subsequence; and determining an encrypted data sequence corresponding to the initial data frame set based on multiple shifted subsequences and the preset binary sequence.

[0050] Among them, the preset binary sequence can be a predefined binary sequence for encrypting data. For example, an XOR operation can be performed on the preset binary sequence and the data subsequence after cyclic shift processing to generate an encrypted subsequence. The binary sequence can be a fixed sequence set in advance, or a sequence generated according to a certain encryption algorithm rule. The preset binary sequence is used for. The cyclic shift processing can be to cyclically shift the elements in the data sequence in a fixed direction (such as left shift or right shift), and by performing cyclic shift processing on each data subsequence, a shift subsequence corresponding to each data subsequence can be obtained. By performing cyclic shift processing on each data subsequence, the original arrangement order of the data subsequence can be changed, thereby increasing the complexity and randomness of encryption. The shift subsequence can be a data subsequence after cyclic shift processing. The shift subsequence can be used to perform an XOR operation with the preset binary sequence to generate an encrypted subsequence.

[0051] Optionally, determining an encrypted data sequence corresponding to the initial data frame set based on multiple shifted subsequences and a preset binary sequence includes: performing an XOR operation on each shifted subsequence and a preset binary sequence to obtain an encrypted subsequence corresponding to each shifted subsequence; and determining the encrypted data sequence corresponding to the initial data frame set based on multiple encrypted subsequences.

[0052] Specifically, a circular left shift operation can be performed on each data subsequence, and each element in the data subsequence is sequentially shifted to the left by a preset number of positions, and the preset number of elements at the leftmost side of the sequence are sequentially moved to the rightmost side of the sequence position, thereby obtaining a shift subsequence corresponding to each data subsequence. Then, a comparison operation is performed on the shift subsequence with a predefined preset binary sequence, and the numbers at the same position of the two sequences are compared. If the numbers are the same, the XOR operation output is 0, and if the numbers are different, the XOR operation output is 1. The XOR operation is performed on each shift subsequence in turn to obtain an encrypted subsequence corresponding to each shift subsequence, and finally, the encrypted data sequence corresponding to the initial data frame set is determined based on the multiple encrypted subsequences corresponding to the multiple data subsequences.

[0053] Exemplarily, the initial data frame set is 11001010101100100111010, the preset group length is 8, the preset number is 3, and the preset binary sequence is 10101101, then the initial data frame set can be divided into multiple data subsequences 01100101, 01011001 and 00111010. When the encryption operation is performed on the first group sequence 01100101, the sequence 01100101 can be cyclically shifted left by 3 bits to obtain the shifted subsequence 00101011, and the shifted subsequence 00101011 is subjected to a bit-by-bit XOR operation with the preset binary sequence 10101101 to obtain the encrypted sequence 10000110 corresponding to the data subsequence. In the same way, the data subsequences 01011001 and 00111010 are cyclically shifted and XORed to obtain multiple encrypted subsequences corresponding to the multiple data subsequences, and the encrypted data sequence corresponding to the initial data frame set is determined based on the multiple encrypted subsequences.

[0054] Optionally, target encrypted data corresponding to the target transmission data is determined based on the initial data frame set and the encrypted data sequence, including: obtaining a preset encryption sequence, first terminal identification information, second terminal identification information and data collection time of the target power data; splicing the binary sequence data frame, the first terminal identification information, the second terminal identification information, the data collection time, the preset encryption sequence, the initial data frame set and the encrypted data sequence through a preset splicing algorithm to obtain the target encrypted data corresponding to the target transmission data.

[0055] The preset encryption sequence can be a pre-set encryption element used to increase complexity and security in the data encryption process. The preset encryption sequence can be a pre-defined fixed encryption sequence; or it can be dynamically generated based on a certain algorithm or rule. When encrypting data, this preset encryption sequence can be embedded in the encrypted data to increase the security of data transmission.

[0056] The preset splicing algorithm may be a pre-set algorithm for splicing binary sequence data frames, first terminal identification information, second terminal identification information, data collection time, preset encryption sequence, initial data frame set and encrypted data sequence. By setting the splicing algorithm to splice the binary sequence data frames, first terminal identification information, second terminal identification information, data collection time, preset encryption sequence, initial data frame set and encrypted data sequence, target encrypted data corresponding to the target transmission data can be obtained.

[0057] Among them, the first terminal identification information can be a unique identifier of the first terminal sending data, which is used to identify the identity information of the first terminal. The first terminal identification information may include identification information such as the device number, area code, and sequence number of the first terminal. The second terminal identification information may be a unique identifier of the second terminal receiving data, which is used to identify the identity information of the second terminal. The second terminal identification information may include. The data collection time of the target power data may be a specific time point or time period for data recording and acquisition for specific power data in the power system. The authenticity and availability of the power system status can be reflected through the target power data and the data collection time of the target power data.

[0058] Optionally, the binary sequence data frame, the first terminal identification information, the second terminal identification information, the data collection time, the preset encryption sequence, the initial data frame set and the encrypted data sequence are spliced ​​through a preset splicing algorithm to obtain target encrypted data corresponding to the target transmission data.

[0059] Optionally, the first terminal identification information, the second terminal identification information and the data collection time may be spliced, and the spliced ​​data information may be added to the data frame header of the target encrypted data; the preset encryption sequence, the initial data frame set and the encrypted data sequence may be spliced ​​to obtain the main body data of the target encrypted data, and the target encrypted data may be obtained by splicing the data frame header data and the main body data.

[0060] Optionally, the first terminal identification information, the second terminal identification information and the data collection time can also be spliced, and the spliced ​​data information is added to the data frame header of the target encrypted data; multiple data subsequences in the initial data frame set and the encryption subsequences corresponding to the multiple data subsequences in the preset encryption sequence are obtained, and then the spliced ​​encryption subsequence corresponding to each data subsequence is obtained according to each data subsequence, the encryption subsequence corresponding to each data subsequence and the encrypted data sequence, and then the multiple spliced ​​encryption subsequences are spliced ​​to obtain the main body data of the target encrypted data, and the target encrypted data is obtained by splicing the data frame header data and the main body data. Among them, each spliced ​​encryption subsequence is spliced ​​by the corresponding data subsequence, the encryption subsequence corresponding to the data subsequence and the encrypted data sequence.

[0061] S130. Transmit the target encrypted data to the second terminal through the data transmission network, so that the second terminal decrypts the target encrypted data through a preset data decryption algorithm to obtain the target transmission data.

[0062] The data transmission network may be a network for transmitting target encrypted data. The data transmission network may transmit the encrypted target encrypted data from the first terminal to the second terminal securely and reliably. The data transmission network may be composed of various physical and logical components, such as routers, switches, optical fibers, copper cables and other components.

[0063] Among them, the second terminal can be a device for receiving target encrypted data, which can be used to receive and decrypt the target encrypted data sent by the first terminal through the data transmission network. The second terminal can be any electronic device capable of processing and decrypting data, such as a computer, a tablet computer, a smart phone and other devices. The second terminal is equipped with a decryption algorithm that is the same as or compatible with the first terminal, and can correctly decrypt the received target encrypted data. The preset data decryption algorithm can be a decryption algorithm corresponding to the preset encryption algorithm. The preset data decryption algorithm can be used to decrypt the target encrypted data sent by the first terminal through the data transmission network. The algorithm usually corresponds to the algorithm used for encryption, but the operation direction is opposite. Through the preset data decryption algorithm, the second terminal can verify the identity of the sender of the data and ensure the integrity and confidentiality of the data.

[0064] The technical solution of the embodiment of the present invention obtains the target transmission data of the first terminal, determines the initial data frame set corresponding to the target transmission data based on the pre-constructed data frame construction algorithm; determines the encrypted data sequence corresponding to the initial data frame set based on the preset data encryption algorithm, and determines the target encrypted data corresponding to the target transmission data according to the initial data frame set and the encrypted data sequence, which can encapsulate the data into encrypted data with lower energy consumption, thereby improving the security of the data. The target encrypted data is transmitted to the second terminal through the data transmission network, so that the second terminal decrypts the target encrypted data through the preset data decryption algorithm to obtain the target transmission data. It can improve the security of data transmission and improve the efficiency of data transmission.

[0065] Embodiment 2

[0066] Figure 2 This is a flowchart of another data encryption and decryption transmission method provided in the second embodiment of the present invention. Based on the above embodiment, this embodiment refines the method of transmitting target encrypted data to a second terminal through a data transmission network so that the second terminal decrypts the target encrypted data through a preset data decryption algorithm to obtain the target transmission data. The same terms as those in the above embodiment are not repeated here. Figure 2 As shown, the method includes:

[0067] S210: Acquire target transmission data of the first terminal, and determine an initial data frame set corresponding to the target transmission data based on a pre-constructed data frame construction algorithm.

[0068] S220. Determine an encrypted data sequence corresponding to the initial data frame set based on a preset data encryption algorithm, and determine target encrypted data corresponding to the target transmission data according to the initial data frame set and the encrypted data sequence.

[0069] S230. Transmit the target encrypted data to the second terminal through the data transmission network. The second terminal decompresses the target encrypted data through a preset decompression algorithm to obtain the first terminal identification information, the second terminal identification information, the data collection time of the target power data, the initial data frame set and the encrypted data sequence.

[0070] Among them, the preset disassembly algorithm can be a pre-built algorithm for disassembling the target encrypted data into multiple components.

[0071] The target encrypted data is transmitted to the second terminal through the data transmission network. The first terminal IP address (IP address, i.e. Internet Protocol Address) and the second terminal IP address may be pre-set according to the network layer protocol, wherein the first terminal IP address may be determined by conversion based on the first terminal identification information; after the transport layer protocol is selected according to the application scenario, the data frame is sent, and the data frame is routed and forwarded through switches and routers in the network according to the second terminal IP address; when the network management platform of the second terminal receives the data frame, it sends a confirmation message to the first terminal. If the first terminal does not receive it within the specified time, it retransmits it according to the retransmission mechanism.

[0072] Specifically, after the target encrypted data is transmitted to the second terminal through the data transmission network, the second terminal can disassemble the target encrypted data through a preset disassembly algorithm to obtain data frame header data and body data. Among them, the data frame header data may include the identification information of the first terminal, the identification information of the second terminal and the data acquisition time of the target power data. The body data is the power data actually transmitted, and the body data may include an initial data frame set, a preset encryption sequence and an encrypted data sequence. By disassembling the target encrypted data through a preset disassembly algorithm, the target encrypted data can be quickly disassembled into multiple parts, thereby improving the efficiency of subsequent processing and analysis. The disassembly process itself can be used as a security mechanism to ensure that only devices with the correct disassembly algorithm can correctly parse the data, which can further ensure data security. And the disassembled data frame header data and body data can be verified separately. For example, the data frame header data can be used to verify the identity of the sender and the receiver and the timeliness of the data; while the body data can be verified by decrypting and comparing with the initial data frame set to verify the integrity and accuracy of the data.

[0073] Optionally, when the target encrypted data is transmitted to the second terminal through the data transmission network, the second terminal disassembles the target encrypted data through a preset disassembly algorithm to obtain data frame header data and main body data. The identification information of the first terminal and the identification information of the second terminal in the disassembled data frame header data can be verified by the second terminal. When the identification information of the first terminal and the identification information of the second terminal in the data frame header data meet the preset decryption conditions, the main body data can be decrypted through the decryption algorithm. When the identification information of the first terminal and the identification information of the second terminal in the data frame header data do not meet the preset decryption conditions, the main body data will not be decrypted, thereby reducing energy loss while ensuring data security.

[0074] S240. When the first terminal identification information and the second terminal identification information meet a preset decryption condition, the encrypted data sequence is decrypted using a preset data decryption algorithm to obtain a decrypted data frame set corresponding to the encrypted data sequence.

[0075] Among them, the preset decryption condition can be a pre-set condition that the disassembled data needs to meet before decrypting the encrypted data sequence in the target encrypted data. For example, the decryption operation is allowed only when the identification information of the two terminals matches or satisfies a certain specific relationship. By setting the preset decryption condition, the security and confidentiality of the data can be ensured to prevent unauthorized access and tampering. The decrypted data frame set can be a data set corresponding to the initial data frame set obtained by decrypting the encrypted data sequence through a preset data decryption algorithm.

[0076] Exemplarily, when the first terminal identification information and the second terminal identification information meet the preset decryption condition, the data frame body part can be divided into groups according to the specific splicing form between the data frame body part and the encrypted data sequence in the received target encrypted data and the preset group length during encryption to obtain multiple encrypted subsequences. The encrypted subsequences are decrypted by performing bit-by-bit XOR operations and reverse cyclic shift processing with a predefined preset binary sequence to obtain a decrypted data frame set corresponding to the encrypted data sequence.

[0077] S250: verify the target encrypted data according to the decrypted data frame set and the initial data frame set, and if the target encrypted data passes the verification, determine the target transmission data corresponding to the initial data frame set.

[0078] Specifically, after decrypting the encrypted data sequence by a preset data decryption algorithm to obtain a decrypted data frame set corresponding to the encrypted data sequence, the decrypted data frame set can be compared with the initial data frame set. If the decrypted data frame set is consistent with the initial data frame set, it means that there is no error or tampering in the data frame during the data transmission process. When the target encrypted data passes the verification, the target transmission data corresponding to the initial data frame set can be determined by a data recovery algorithm based on the decrypted data frame set and the initial data frame set. The data recovery algorithm can be an algorithm for determining the target transmission data corresponding to the initial data frame set based on the decrypted data frame set and the initial data frame set.

[0079] Optionally, after the second terminal decrypts the target encrypted data using a preset data decryption algorithm, it also includes: when the target encrypted data fails to pass verification, the second terminal sends a data retransmission request to the first terminal; the first terminal regenerates the target encrypted data corresponding to the target transmission data according to the data retransmission request, and transmits the target encrypted data to the second terminal through the data transmission network.

[0080] The data retransmission request may be a data retransmission request sent to the first terminal when the second terminal decrypts the target encrypted data and finds that the decrypted data frame set is inconsistent with the original data frame set before encryption.

[0081] Exemplarily, after decrypting the target encrypted data, the second terminal can compare the decrypted data frame set obtained by decryption with the initial data frame set before encryption. If the decrypted data frame set obtained by decryption is inconsistent with the initial data frame set before encryption, a data retransmission request is sent to the first terminal. When the first terminal receives the data retransmission request, it can determine based on the data retransmission request that the encrypted data previously transmitted to the second terminal has not been correctly restored to the original data after decryption, and there may be a transmission error or data tampering. At this time, the first terminal can regenerate the target encrypted data corresponding to the target transmission data based on the data retransmission request, and retransmit the target encrypted data to the second terminal through the data transmission network, so that the second terminal can obtain the target transmission data by re-decrypting the received target encrypted data.

[0082] The technical solution of the embodiment of the present invention obtains the target transmission data of the first terminal, determines the initial data frame set corresponding to the target transmission data based on the pre-constructed data frame construction algorithm; determines the encrypted data sequence corresponding to the initial data frame set based on the preset data encryption algorithm, and determines the target encrypted data corresponding to the target transmission data according to the initial data frame set and the encrypted data sequence, which can encapsulate the data into encrypted data with lower energy consumption, thereby improving the security of the data. The target encrypted data is transmitted to the second terminal through the data transmission network, so that the second terminal decrypts the target encrypted data through the preset data decryption algorithm to obtain the target transmission data. It can improve the security of data transmission and improve the efficiency of data transmission.
