[0041] Figure 1 is a system architecture schematic diagram of an embodiment of the present application.

[0042] Figure 2 is a method flowchart of an embodiment of the present application. DETAILED DESCRIPTION

[0043] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present application is not limited by the specific embodiments.

[0044] The data security capability in the current information transmission mechanism still needs to be strengthened. Through analysis, the weak points of the data security in the current information transmission mechanism can be summarized as follows: 1. In the initial configuration process, the server needs to send the sequence generation formula to the information terminal. If an unauthorized person listens to this information through sniffing attack, the security cannot be realized. In addition, if the sequence generation formula is pre-stored in the information terminal, if the information terminal is discarded and replaced, the factory will consume a lot of manpower and material resources to delete the sequence generation formula stored in the information terminal. It can be understood that even if a large amount of cost is consumed to delete the related data, there is currently a related technology to recover the deleted files. If the memory in the terminal is removed, the terminal generally needs to be disassembled destructively, so the terminal that can be depreciated and recycled cannot be recycled, which will also cause losses to the factory. 2. The current data encryption method generally generates a binary sequence through a random number and a sequence generation formula. However, once the random number and the sequence generation formula are known by an unauthorized person, in theory, as long as the unauthorized person uses the encrypted sequence (obtained by the random number and the sequence generation formula) to perform XOR operation on the listened information, the unauthorized person can know the information that should be kept secret. At this time, the system cannot use another method to increase the security. The method of the present application aims to solve the above technical problems.

[0045] Embodiment 1

[0046] Figure 1 is a system architecture diagram of an embodiment of the present application. As shown in the figure, the system of the present application includes a server, an information terminal, a first data security terminal and a second data security terminal. The information terminal can be a low-cost electronic terminal with communication capability (the communication mode can be optical fiber, 5G communication or WiFi communication) and can collect boiler production information. The data security terminal can be a conventional desktop computer. The server and the information terminal communicate through the conventional wide-area Internet, and the data security terminal and the information terminal communicate through the local area network.

[0047] Embodiment 2

[0048] Figure 2 is a method flowchart of an embodiment of the present application. As shown in the figure, the method of the present application includes the following steps:

[0049] Step 1: sending a sequence generation formula indicator from the server to the information terminal, wherein the sequence generation formula indicator indicates the sequence generation formula to be used by the information terminal; in an example, the sequence generation formula indicator can be a binary number;

[0050] Step 2: forwarding the sequence generation formula indicator by the information terminal to the first data security terminal through the local area network; those skilled in the art can understand that, since the information terminal communicates with the first data security terminal through the local area network, the security is higher than that of communication over the wide area network, and the number of communication nodes in the local area network is much smaller than that of communication over the wide area network, which also facilitates the factory to better monitor the security risks in the local area network, and the factory can take corresponding action in time once the local area network is found to be invaded;

[0051] Step 3: after receiving the sequence generation formula indicator at the first data security terminal, sending the sequence generation formula by the first data security terminal to the information terminal; those skilled in the art can understand that, according to the description of steps 2 and 3, since the information terminal can request the sequence generation formula from the first data security terminal, the information terminal does not need to store the sequence generation formula, thus avoiding the problem of spending a large amount of cost to delete the information stored in the information terminal when the information terminal is replaced or eliminated; of course, the first data security terminal still needs to store the sequence generation formula, but it needs to be understood that there can be thousands of information terminals in a factory, but a factory generally only needs one first data security terminal, so when the first data security terminal is eliminated or replaced, its hard disk can be removed and kept in the factory, and only the remaining computing device is sold, which does not significantly increase the cost of the factory.

[0052] Step 4: sending the sequence adjustment mode indicator by the server to the information terminal, wherein the sequence adjustment mode indicator indicates the sequence adjustment mode to be used by the information terminal;

[0053] Step 5: forwarding the sequence adjustment mode indicator by the information terminal to the second data security terminal through the local area network; in one example, if it is necessary to further improve the security performance, an independent local area network between the information terminal and the second data security terminal can be set, that is, the information terminal communicates with the first data security terminal through the first local area network, and at the same time, the information terminal communicates with the second data security terminal through the second local area network, and the first local area network and the second local area network are two independent local area networks.

[0054] Step 6: after receiving the sequence adjustment mode indicator at the second data security terminal, sending the sequence adjustment mode by the second data security terminal to the information terminal.

[0055] Embodiment 2

[0056] In embodiment 2, the method further comprises:

[0057] sending a random number by the server to the information terminal; in one example, it is assumed that the random number is 1000;

[0058] The information terminal converts the random number into an encryption sequence based on the sequence generation formula; in one example, it is assumed that the sequence generation formula currently used is as follows:

[0059]

[0060] In the formula, x is the random number, y is the result obtained, and after rounding down y, the value of y after rounding down is converted into a binary number, i.e., the encryption sequence can be obtained; in one example, continuing the example in which the preceding random number is 1000, the calculated y value is 11023.1, and after rounding down, it is 11023, which is converted into a binary number as "10101100001111", i.e., the encryption sequence is "10101100001111".

[0061] The information terminal adjusts the encryption sequence based on the sequence adjustment mode to obtain an adjusted encryption sequence, wherein the adjusted encryption sequence is used for exclusive-OR operation on the production information.

[0062] Embodiment 3

[0063] In Embodiment 3, the sequence generation formula indicator includes at least a first sequence generation formula indicator and a second sequence generation formula indicator, wherein the first sequence generation formula indicator indicates that the information terminal is to use the first sequence generation formula, and the second sequence generation formula indicator indicates that the information terminal is to use the second sequence generation formula, wherein the first sequence generation formula is different from the second sequence generation formula. In one example, the first data security terminal can store the following mapping table, so that after the first data security terminal receives the sequence generation formula indicator, it can determine the sequence generation formula corresponding to each indicator,

[0064]

[0065] It should be understood that the above table is only an example, and in an actual system, the sequence generation formula indicator may, for example, have 4, 5, 10, or even more, and the corresponding sequence generation formula may, for example, have 4, 5, 10, or even more. In one example, the public

[0066] Formula 1 can be

[0067]

[0068] Formula 2 can be

[0069]

[0070] Embodiment 4

[0071] In Embodiment 4, the sequence adjustment mode includes the following:

[0072] the interception manner of the encryption sequence; in an example, taking the encryption sequence "10101100001111" as an example, the interception manner of the encryption sequence can be to remove the binary number of the first bit and the binary number of the tail bit, and the result is "010110000111";

[0073] the order adjustment manner of the binary number in the encryption sequence; in an example, the order adjustment manner of the binary number can be to place the first three binary numbers of the binary sequence after interception at the end of the sequence, and if the binary sequence after interception is "010110000111", the binary number after order adjustment is "110000111010";

[0074] the truncation manner of the encryption sequence when the length of the encryption sequence after interception is greater than the length of the production information; in an example, for example, a certain production information is converted into a binary number "1101101" after interception, and then the length of the encryption sequence after interception is greater than the length of the production information, at this time, the truncation operation of the encryption sequence after interception can be to continuously truncate a number of binary numbers in the middle of the sequence from the fourth bit of the encryption sequence after interception, so that the length of the encryption sequence after truncation is equal to the length of the production information, in an example, the binary number after order adjustment is "110000111010", the encryption sequence after truncation is "1101010", and finally the encryption sequence after truncation is used to perform XOR operation with the binary sequence of the production information, and the result is "0000111";

[0075] the filling manner of the encryption sequence when the length of the encryption sequence is less than the length of the production information. In an example, for example, a certain production information is converted into a binary number "110110111111111100" after interception, and then the length of the encryption sequence after interception is less than the length of the production information, at this time, the filling operation of the encryption sequence after interception can be to continuously take a number of binary numbers in the middle of the sequence from the fourth bit of the encryption sequence after interception, and copy and connect them to the end of the encryption sequence after interception, so that the length of the encryption sequence after filling is equal to the length of the production information, in an example, the binary number after order adjustment is "110000111010", the encryption sequence after filling is "110000111010000111", and finally the encryption sequence after filling is used to perform XOR operation with the binary sequence of the production information, and the result is "000110000101111011". It should be understood that, according to the introduction of embodiment 4, in a real system, the interception, order adjustment, and truncation operation of the encryption sequence should be performed in sequence, or the interception, order adjustment, and filling operation of the encryption sequence should be performed in sequence.

[0076] In a preferred embodiment, the sequence adjustment mode indicator comprises at least a first sequence adjustment mode indicator and a second sequence adjustment mode indicator, wherein the first sequence adjustment mode indicator indicates that the information terminal is to use a first sequence adjustment mode, and the second sequence adjustment mode indicator indicates that the information terminal is to use a second sequence adjustment mode, wherein the first sequence adjustment mode comprises a first truncation mode, a first order adjustment mode, a first cut-off mode and a first padding mode, and the second sequence adjustment mode comprises a second truncation mode, a second order adjustment mode, a second cut-off mode and a second padding mode, wherein the first truncation mode is different from the second truncation mode, the first order adjustment mode is different from the second order adjustment mode, the first cut-off mode is different from the second cut-off mode, and the first padding mode is different from the second padding mode.
