[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present application are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0026] To better understand the embodiments of the present application, some nouns or terms that appear in the description process of the embodiments of the present application are translated and explained as follows:

[0027] The principle of the lowest energy: That is, for a multi-electron atom in the ground state, when arranging the extranuclear electrons, they always occupy the orbit with the lowest energy as much as possible first, and then are distributed to the orbits with higher energy levels in turn according to the order of the approximate energy levels of the atomic orbits, so as to make the energy of the whole atom the lowest. Among them, the level of the energy of the atomic orbit (also called energy level) is mainly determined by the principal quantum number N and the angular quantum number L. When L is the same, the larger N is, the higher the energy of the atomic orbit. For example, E 1s <E 2s <E 3s ; when N is the same, the larger L is, the higher the energy of the atomic orbit. For example, E 1s <E 1p <E 1d; When N and L are both different, the attraction of the atomic nucleus for electrons and the repulsion between electrons must be considered simultaneously. Since the presence of other electrons often weakens the attraction of the atomic nucleus for outer electrons, the energy levels of multi-electron atoms are staggered. Therefore, an approximate energy level diagram of multi-electron atomic orbitals is proposed. Small circles are used to represent atomic orbitals, which are arranged in order of increasing energy. Orbitals with relatively close energies are placed in the same box to form an energy level group.

[0028] Example 1

[0029] The related information encryption method is based on a certain algorithm and uses a specific scheme to change the appearance of important data information during network transmission, and then the receiving party compares the data information before and after the change. This method sets the same encryption level for all contents in the data information and does not consider the data segment information with different degrees of importance / sensitivity in the data information. This method greatly reduces the security of user information.

[0030] To solve the above problems, the embodiments of the present application provide an information encryption method. This method can set different encryption levels for each segment of the sub-information to be encrypted according to the security levels of each segment of the sub-information to be encrypted in the information to be encrypted, and according to the position of each segment of the sub-information to be encrypted in the information to be encrypted and the encryption level, use the principle of the lowest energy to set the sorting identifier of each segment of the sub-information to be encrypted, and add the sorting identifier to the information to be encrypted for encoding to obtain the encrypted information, so that users can set different encryption levels for each segment of the encrypted information according to their needs during actual application, improving the security of user information.

[0031] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0032] Figure 1 is a schematic flowchart of an optional information encryption method according to an embodiment of the present application. As Figure 1 shown, the method at least includes steps S102 - S108, where:

[0033] Step S102, obtain the first information to be encrypted, and the first information to be encrypted includes multiple segments of the first sub-information to be encrypted.

[0034] Among them, the first information to be encrypted can be the information to be encrypted obtained from an information library, such as: ID number information, email address information, bank card number information, etc.

[0035] For example, the first information to be encrypted is the user's mobile phone number information, such as 1*0313*7223. Each digit in the mobile phone number is split to obtain multiple segments of the first sub-information to be encrypted. Subsequently, when encrypting the information, different encryption levels are set accordingly based on the digital segment information that the user wants to protect key points.

[0036] Step S104, determine the sorting identifier for each segment of the first sub-information to be encrypted. The sorting identifier is used to reflect the position information and encryption level information of each first sub-information to be encrypted in the first information to be encrypted.

[0037] Among them, the sorting identifier can be a prefix sorting identifier or a suffix sorting identifier.

[0038] Optionally, for each segment of the first sub-information to be encrypted, obtain the security level of the first sub-information to be encrypted, and determine the encryption level identifier of the first sub-information to be encrypted according to the security level; according to the position of the first sub-information to be encrypted in the first information to be encrypted and the encryption level identifier, use the principle of the lowest energy to determine the position identifier of the first sub-information to be encrypted, where the position identifier corresponds to the principal quantum number, and the encryption level identifier corresponds to the angular quantum number; determine the sorting identifier of the first sub-information to be encrypted according to the encryption level identifier and the position identifier.

[0039] As an alternative implementation, for multiple segments of the first sub-information to be encrypted with the same security level, sort the multiple segments of the first sub-information to be encrypted according to their positions in the first information to be encrypted to obtain the position identifiers of the multiple segments of the first sub-information to be encrypted.

[0040] Generally, for Figure 2 the shown lowest energy principle diagram, when the principal quantum numbers are the same, the larger the angular quantum number, the greater the atomic energy. For example, 3s < 3p < 3f; when the angular quantum numbers are the same, the larger the principal quantum number, the greater the atomic energy. For example, 1s < 2s < 3s.

[0041] For this application, for multiple segments of the first sub-information to be encrypted with the same security level, for example, for the same encryption level identifier p, sort them according to the positions of the numbers 0, 1, 7, 3 in the user's phone number to obtain the position identifiers corresponding to each digital information, where the position identifier of the number 0 is 2, the position identifier of the number 1 is 3, the position identifier of the number 7 is 4, and the position identifier of the number 3 is 5.

[0042] Specifically, taking the user's mobile phone number 1*0313*7223 as an example, since the user's mobile phone number contains sensitive information of different security levels, different encryption level identifiers need to be set for sensitive information of different levels when encrypting. When the security level of the user's mobile phone number is medium - low, according to the four security levels preset by the system, namely s, p, d, and f, the encryption level identifiers of each digit are set. Among them, the encryption level identifiers of the first digit 1, the second digit *, the fourth digit 3, the sixth digit 3, and the ninth digit 2 are s; the encryption level identifiers of the third digit 0, the fifth digit 1, the eighth digit 7, and the eleventh digit 3 are p; the encryption level identifiers of the seventh digit * and the tenth digit 2 are d.

[0043] Next, based on the position and encryption level identifier of each digit, use the lowest - energy schematic diagram as shown in Figure 2 to determine the position identifier of each digit.

[0044] Finally, determine the sorting identifier based on the encryption level identifier and position identifier of each digit. Figure 3 Fig. shows a schematic diagram of an optional sorting identifier. Among them, the sorting identifier corresponding to the first digit 1 is 1s, the sorting identifier corresponding to the second digit * is 2s, the sorting identifier corresponding to the third digit 0 is 2p, the sorting identifier corresponding to the fourth digit 3 is 3s, the sorting identifier corresponding to the fifth digit 1 is 3p, the sorting identifier corresponding to the sixth digit 3 is 4s, the sorting identifier corresponding to the seventh digit * is 3d, the sorting identifier corresponding to the eighth digit 7 is 4p, the sorting identifier corresponding to the ninth digit 2 is 5s, the sorting identifier corresponding to the tenth digit 2 is 4d, and the sorting identifier corresponding to the eleventh digit 3 is 5p.

[0045] Step S106, add the sorting identifier to the first information to be encrypted to obtain the second information to be encrypted.

[0046] Optionally, for each segment of the first sub - information to be encrypted, splice the sorting identifier of the first sub - information to be encrypted with the first sub - information to be encrypted to obtain the second sub - information to be encrypted; splice each segment of the second sub - information to be encrypted to obtain the second information to be encrypted.

[0047] Optionally, randomly sort each segment of the second sub - information to be encrypted, and splice the randomly sorted segments of the second sub - information to be encrypted to obtain the second information to be encrypted.

[0048] Optionally, add a preset segmentation identifier between each segment of the second sub - information to be encrypted; splice each segment of the second sub - information to be encrypted and the segmentation identifier to obtain the second information to be encrypted.

[0049] Specifically, to facilitate the identification of each segment of sub-information to be encrypted, the segmentation identifier should avoid any characters that may appear in the information to be encrypted, so as to ensure distinction from other parts of the encrypted information. Therefore, the segmentation identifier can be formed by a single character or a combination of multiple characters into other strings that will never appear, such as tab characters, line break characters, number symbols, etc.

[0050] For example, continuing with the user's phone number as an example, each digit is concatenated with its corresponding suffix sorting identifier to obtain 11s, *2s, 02p, 33s, 13p, 34s, *3d, 74p, 25s, 24d, 35p. Then, the above digits are randomly sorted, such as 11s, 74p, 33s, 25s, 24d, 13p, 34s, 35p, *3d, *2s, 02p, and a segmentation identifier is added between each segment of information. Among them, no segmentation identifier needs to be concatenated after the last segment of information. Finally, the segments of information are arranged in an order other than the original order, and a segmentation identifier is added between each segment of information to obtain the second piece of information to be encrypted. When the segmentation identifier is &%&, the second piece of information to be encrypted can be 11s&%&74p&%&33s&%&25s&%&24d&%&13p&%&34s&%&35p&%&*3d&%&*2s&%&02p.

[0051] Step S108, encode the second piece of information to be encrypted based on a preset encoding rule to obtain the target encrypted information.

[0052] Optionally, the preset encoding rule can be base64 encoding, ASCII code encoding, etc. In the embodiment of the present application, base64 encoding is preferably used. Among them, base64 is a method for identifying binary data based on 64 printable characters, and is often used in occasions for processing text data, representing, transmitting, and storing some binary data, including emails or some complex data.

[0053] When the preset encoding rule selects a reversible encoding method, the preset encoding rule can be a symmetric encoding rule or an asymmetric encoding rule. Among them, when the data volume is large, the symmetric encoding rule can be selected as the preset encoding rule, and the data encoding speed of this symmetric encoding rule is relatively fast; when the security requirements for encrypted data are high, the asymmetric encoding rule can be selected as the preset encoding rule.

[0054] It should be noted that the selection of the preset encoding rule is not restricted, and a suitable reversible encoding method is specifically selected according to the actual application scenario.

[0055] Specifically, in the embodiments of the present application, the re - spliced string "11s&%&74p&%&33s&%&25s&%&24d&%&13p&%&34s&%&35p&%&*3d&%&*2s&%&02p" is encoded by the base64 encoding method. For example, "11s" can be encoded to obtain "MTFz" through base64 encoding, and "&%&" can be encoded to obtain "JTI2JTI1JTI2" through base64 encoding. Therefore, the following encrypted information can be obtained after encoding the above string: "MTFzJTI2JTI1JTI2NzRwJTI2JTI1JTI2MzNzJTI2JTI1JTI2MjVzJTI2JTI1JTI2MjRkJTI2JT I1JTI2MTNwJTI2JTI1JTI2MzRzJTI2JTI1JTI2MzVwJTI2JTI1JTI2KjNkJTI2JTI1JTI2KjJz JTI2JTI1JTI2MDJw".

[0056] After the encryption operation on the first information to be encrypted is completed, the subsequent decryption operation can directly operate on the target encrypted information without using the first information to be encrypted for operation processing.

[0057] As an optional implementation manner, after storing the target encrypted information, the first information to be encrypted can be deleted. This can not only save the storage space of the information library but also prevent the leakage of the first information to be encrypted, thereby enhancing the security of user information storage.

[0058] In the embodiments of the present application, the first information to be encrypted is obtained, and the first information to be encrypted includes multiple segments of first sub - information to be encrypted; the sorting identifier of each segment of the first sub - information to be encrypted is determined, and the sorting identifier is used to reflect the position information and encryption level information of each first sub - information to be encrypted in the first information to be encrypted; the sorting identifier is added to the first information to be encrypted to obtain the second information to be encrypted; the second information to be encrypted is encoded based on a preset encoding rule to obtain the target encrypted information, thereby realizing custom - setting the encryption level to obtain the sorting identifier, and further solving the technical problem that the encryption level of the encrypted information cannot be custom - set in the related art and improving the security of user information.

[0059] Embodiment 2

[0060] The embodiments of the present application provide an information decryption method. After decrypting the encrypted information through a preset decoding rule, the final target decrypted information can be obtained according to the sorting identifier of each sub - information to be decrypted.

[0061] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0062] Figure 4 It is a schematic flowchart of an optional information encryption method according to an embodiment of the present application. As Figure 4 shown, the method at least includes steps S402 - S406, where:

[0063] Step S402, obtain encrypted information, where the encrypted information includes multiple segments of encrypted sub-information.

[0064] Step S404, for each segment of encrypted sub-information, decode the encrypted sub-information based on a preset decoding rule to obtain sub-information to be decrypted. Among them, the sub-information to be decrypted includes: target decryption sub-information and a sorting identifier, and the sorting identifier is used to reflect the position information and encryption level information of the target decryption sub-information in the target decryption information;

[0065] Step S406, sort each segment of target decryption sub-information according to the sorting identifier to obtain the target decryption information.

[0066] Optionally, the preset decoding rule can be base64 decoding, ASCII code decoding, etc. In the embodiment of the present application, base64 decoding is preferably used.

[0067] It should be noted that the selection of the preset decoding rule is not limited, and a suitable reversible decoding method is specifically selected according to the actual application scenario.

[0068] For example, first obtain the target encrypted information obtained by the information encryption method. The content of the encrypted information is MTFzJTI2JTI1JTI2NzRwJTI2JTI1JTI2MzNzJTI2JTI1JTI2MjVzJTI2JTI1JTI2MjRkJTI2JTI1JTI2MTNwJTI2JTI1JTI2MzRzJTI2JTI1JTI2MzVwJTI2JTI1JTI2KjNkJTI2JTI1JTI2KjJzJTI2JTI1JTI2MDJw. Among them, the encrypted information includes multiple segments of encrypted sub-information, such as MTFzJTI2JTI1JTI2, NzRwJTI2JTI1JTI2, MzNzJTI2JTI1JTI2, MjVzJTI2JTI1JTI2, MjRkJTI2JTI1JTI2, MTNwJTI2JTI1JTI2, MzRzJTI2JTI1JTI2, MzVwJTI2JTI1JTI2, KjNkJTI2JTI1JTI2, KjJzJTI2JTI1JTI2, MDJw; then decode each segment of the above information through base64 decoding to obtain the following data information: {"11s","74p","33s","25s","24d","13p","34s","35p","*3d","*2s","02p"}, where each segment of decoded data information includes: the target sub-information to be decrypted and the sorting identifier; finally, sort each segment of data information according to the sorting identifier to obtain the target decrypted information, that is, the user's mobile phone number 1*0313*7223.

The information encryption device at least includes an acquisition module 51, a determination module 52, an addition model 53, and an encoding module 54, where:

[0071] The acquisition module 51 is configured to acquire the first information to be encrypted, and the first information to be encrypted contains multiple segments of the first sub-information to be encrypted.
