Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a data security transmission method based on industrial production, including:
s101: and determining the component parameters of the component to be produced according to the work order task.
A work order task is a production plan made up of one or more jobs, generated by a master device. The main control device is an entity device with data transceiving capacity and calculation processing capacity, and can generate work order tasks, acquire and distribute product information and the like.
After the staff sets the component parameters of the current component to be produced through the master control equipment, the server can determine the component parameters of the component to be produced according to the work order task generated by the master control equipment. The part parameters comprise application products, yield, production serial numbers and production sizes, for example, the part to be produced is steel, the part parameters are Yangtze river bridge cross beams, the yield is 1 piece, the serial numbers are 20220208-5, and the length is 10m, the width is 10cm, and the height is 30 m. It should be noted that, a parameter setting template exists in the main control device, and a worker can set component parameters through the parameter setting template, and finally, the generated component parameters exist in a character string form.
S102: and performing character splitting processing on the component parameters to obtain a plurality of characters contained in the component parameters, and performing analysis processing on the plurality of characters to respectively convert the plurality of characters into corresponding American Standard Code for Information Interchange (ASCII) values.
After obtaining the component parameters, the server needs to sequentially split the single characters included in the component parameters, so as to extract a plurality of characters. After the plurality of characters are extracted, each character is subjected to parsing processing (e.g., ord conversion) to convert each of the plurality of split characters into its corresponding ASCII value.
S103: and acquiring a preset first key and a preset second key, and encrypting ASCII values corresponding to the characters respectively according to the first key and the second key to obtain a plurality of encrypted ciphertext fragments.
After the conversion between the characters and the ASCII values is completed, the converted ASCII values are required to be encrypted, so that the safe transmission of data is realized. In the embodiment of the application, a double-key mechanism is adopted for encryption, a first key and a second key are a group of key pairs, wherein the first key corresponds to a binary conversion rule, and the second key is an encryption template which can be randomly generated. Only on the basis of determining the key pair described above can secure encryption of the component parameters be achieved.
In one embodiment, the server may generate the first key and the second key for encrypting the ASCII value through an encryption tool. Specifically, a binary conversion rule corresponding to the component parameter is determined, and a first key is generated according to the number of bits of the binary conversion rule. Taking the 52-ary transformation rule as an example, the first key may be represented as n-52. The system conversion rule can be adjusted according to the actual network throughput, for example, when the network throughput is high, the current data transmission efficiency is high, and a low-digit system conversion rule can be selected to encrypt the ASCII value; when the network throughput is low, a high-order binary conversion rule is usually adopted, so that the transmitted data volume is reduced, and the transmission speed is increased. Of course, the binary conversion rule can also be customized according to both communication parties.
Further, according to the selected binary conversion rule, a data format after the binary conversion is completed is determined, and according to the data format, a character string containing a plurality of characters is generated to serve as a second key base. The string length of the second key is not less than the number of binary digits n, and the second key contains a plurality of characters which are different, for example, the second key may be expressed as base ═ 0123456789 abcdefghijklmnnopqrstwvwxzabcdefghijklmnopqrstwxyz'. The second key is an encryption template, and the encrypted ciphertext exists in the form of the encryption template.
After generating the key pair and completing distribution thereof, the server determines a correspondent having the first key and the second key, and constructs a local area communication network for the correspondent. The local area communication network adopts a point-to-point communication mechanism, only a communication party holding a first secret key and a second secret key can enter the local area communication network, and the first secret key and the second secret key are only effective in the local area communication network. Therefore, even if the third party maliciously steals the key pair and does not belong to the local area communication network, the key pair cannot take effect, and the data security is further ensured.
In one embodiment, the server obtains a first key and a second key generated in advance after converting all of a plurality of characters contained in the component parameter into ASCII values, and encrypts the ASCII value corresponding to each character through the obtained first key and second key to obtain an encrypted ciphertext fragment. Each ciphertext segment corresponds to a character in the component parameter.
Specifically, the ASCII value is denoted as a, and a first quotient obtained by dividing a by the carry digit n is used as the first digit of the encrypted ciphertext fragment. And after the quotient is finished, comparing the first remainder obtained after the quotient is finished with the carry digit, if the first remainder is still larger than the carry digit, continuously dividing the first remainder by the carry digit, and adding the obtained second quotient value to the first quotient value. After the second quotient is performed, the magnitude relation between the second remainder obtained after the second quotient and the carry digit is compared again, if the second remainder is still larger than the carry digit, the second remainder is divided by the carry digit, and a third quotient value obtained by performing the quotient is added to the second quotient value. Thus, the quotient string obtained through multiple iterations of quotient forms the final ciphertext segment. It should be noted that, in the iterative quotient-making process, once the remainder obtained after quotient-making is smaller than the carry digit number, the operation is stopped, and the obtained quotient value string is a ciphertext segment.
In one embodiment, to simplify the encryption process, the server needs to unify the format of the ciphertext fragments. If the digit of the ciphertext segment is smaller than the preset value, bit complementing is carried out before the first bit of the ciphertext segment, so that the digit of the ciphertext segment after bit complementing can reach a uniform preset value. In addition, when performing bit padding, a "0" padding method is generally used. Taking the first key n as 52 as an example, it can ensure that the number of bits of the ciphertext fragment does not exceed three bits when encrypting the ASCII value, and the transmission speed is faster. And under the condition that the digit of the ciphertext segment does not exceed three digits, 0 can be complemented before the first digit of the ciphertext segment.
S104: and splicing the plurality of ciphertext sections to obtain a ciphertext corresponding to the component parameter.
One ciphertext segment corresponds to one character in the component parameter, so after a plurality of ciphertext segments are obtained, the ciphertext segments need to be spliced to obtain a complete ciphertext corresponding to the plurality of characters contained in the component parameter.
S105: and compressing the ciphertext, and sending the compressed designated ciphertext to a target production line area corresponding to the part to be produced so as to complete the production of the part to be produced according to the designated ciphertext.
In order to achieve lossless transmission of data, a preset compression algorithm (for example, a compression function zlib. compression ()) needs to be called to compress a ciphertext, so as to obtain a compressed designated ciphertext. And then sending the specified ciphertext to a target production line area in the local area communication network, decompressing the specified ciphertext by a decompression algorithm (such as zlib. uncompressions ()) after the specified ciphertext is received by the target production line area, splitting the decompressed ciphertext to obtain a plurality of ciphertext segments after decompression, decrypting the ciphertext segments sequentially by a second key and a first key, finally restoring the obtained ASCII value after decryption into corresponding characters, and splicing the characters according to the arrangement sequence, thereby obtaining the transmitted component parameters.
In the industrial production process, each part to be produced corresponds to a plurality of production line areas, and the production raw material amount of each production line area is different. Before ciphertext transmission, the server selects a production line area with sufficient raw materials as a target production line area according to the yield of the current part to be produced. After the target production line area is determined, the target production line area can receive and decrypt the component parameters, and accordingly, the corresponding component to be produced is produced.
After the target production line area finishes production, the production state information of the current produced part needs to be acquired, encrypted and returned to the main control equipment, and the main control equipment can update the work order task according to the returned production state information. It should be noted that the encryption and decryption process of the production state information is the same as the encryption and decryption process of the component parameter, and details thereof are not repeated. The production state information is used for reflecting the production condition of the component, including the produced quantity, the qualified product quantity and the like. If the raw materials of the current target production line area can not complete all production tasks, the master control equipment can update the work order task according to the fed-back incomplete production data, and simultaneously re-determine a new production line area from the plurality of production line areas so as to facilitate the production tasks of the incomplete parts. If defective products exist in the parts produced in the current target production line area, the main control equipment needs to add the production information of the defective products in the work order task after receiving the production state information, and secondary production of the defective products is carried out through the current target production line area again, so that the quality of the produced parts is ensured.
Fig. 2 is a diagram of an example of an encryption process according to an embodiment of the present application. As shown in FIG. 2, the part to be produced is steel, and the part parameters are 'Changjiang river bridge crossbeam, yield 1 piece, serial number 20220208-5, length 10m, width 10cm and height 30 m'. And carrying out character splitting processing on the component parameters to obtain a plurality of characters, and then carrying out analysis processing on different characters to convert the different characters into corresponding ASCII values. The converted ASCII values are encrypted (e.g., 52-ary conversion) according to the first and second keys, and the encrypted ciphertext fragments are complemented to obtain bit-aligned ciphertext fragments. And splicing the aligned ciphertext sections to obtain a complete transmission ciphertext, then compressing the complete ciphertext through a compression processing algorithm, and finally obtaining the designated ciphertext through compression processing, wherein the designated ciphertext is the data to be transmitted during data interaction.
The above is the method embodiment proposed by the present application. Based on the same idea, some embodiments of the present application further provide a device and a non-volatile computer storage medium corresponding to the above method.
