Specific embodiments of the present invention have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

For a clear understanding of the technical solutions of the present application, the prior art solutions will be described in detail first. With the continuous development of network technology, many traditional works are changed from offline to online. For enterprises, when working on line, a large amount of file data needs to be transmitted every day, and related data related to enterprise privacy may exist in the file data, in order to avoid leakage of the content of the file data, a plaintext password is usually set for the file data. Plaintext passwords, i.e., passwords commonly used by users, include the digits 0-9, english letter cases, special symbols, and so forth. Because the password composition is relatively simple and is easy to be cracked by other people, when the enterprise user uses the plaintext password, the plaintext password can be further encrypted, so that the plaintext password is prevented from being cracked by other people, and the security of file data transmission is improved. The conventional encryption methods include an AES encryption method and an MD5 encryption method, and the two encryption methods have relatively complex algorithms, but have relatively high popularity, and more people engage in related encryption algorithms, so that the plaintext password encrypted by the two encryption methods is more and more cracked by other people. Thus, the security of the two encryption modes of plaintext ciphers is low at present.

Therefore, aiming at the technical problem of lower security of the encryption mode of the plaintext cipher in the prior art, the inventor discovers in research that in order to solve the problem of lower security of the encryption mode of the plaintext cipher at present, a new encryption mode can be constructed, and the security of the encryption of the plaintext cipher is increased by a novel and complex encryption mode. Firstly, acquiring a plaintext password input by a user, and then determining the mapping relation between each character in the plaintext password and elements in an element periodic table stored in an encryption database through a preset encryption database and combining the plaintext password. Therefore, the plaintext password can be converted into the target password through the mapping relation, and meanwhile, as the target password corresponds to each element of the periodic table of elements, when other people crack the target password, the meaning of each character in the target password is difficult to crack, and compared with the current common plaintext password encryption mode, the safety is higher.

The inventor puts forward the technical scheme of the application based on the creative discovery.

The application scenario of the plaintext cipher encryption method provided by the embodiment of the present invention is described below. As shown in fig. 1, 1 is a first electronic device, 2 is a second electronic device, and 3 is a display device. The network architecture of the application scene corresponding to the plaintext cipher encryption method provided by the embodiment of the invention comprises the following steps: a first electronic device 1, a second electronic device 2 and a display device 3. The first electronic device 1 belongs to a user who transmits file data, and is used for encrypting a plaintext password input by the user. The second electronic device 2 belongs to a user receiving file data for decrypting an encrypted plaintext password. Wherein both the first electronic device 1 and the second electronic device 2 have an encryption database, i.e. both store the mapping relation between the individual characters in the plaintext password and the elements in the periodic table of elements. When a user who needs to send file data needs to set a password for the file data, firstly, a plaintext password is set for the file, and then the plaintext password input by the user is acquired through the first electronic device 1. The first electronic device 1 determines, by combining a preset encryption database with the plaintext password, a mapping relationship between each character in the plaintext password and an element in the periodic table of elements stored in the encryption database. So that the plaintext password can be converted into the target password through the mapping relation. After the target password is generated, the user can send the file data to the second electronic device 2 through the first electronic device 1, and the second electronic device 2 determines the mapping relationship between each character in the plaintext password and the elements in the target password according to the target password and a preset encryption database, so as to determine the plaintext password and output the plaintext password to the display device 3. At this time, the user who receives the file data may input a plaintext password displayed by the display device 3 to open the corresponding file data. When others prepare to crack the target password to obtain the plaintext password, as the target password corresponds to each element of the periodic table of elements, when others crack the target password, the meaning of each character in the target password is difficult to crack, and compared with the current common plaintext password encryption mode, the security is higher.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

Fig. 2 is a flow chart of a plaintext cipher encryption method according to a first embodiment of the present invention, as shown in fig. 2, in this embodiment, an execution body of the present invention is a plaintext cipher encryption apparatus, and the plaintext cipher encryption apparatus may be integrated in an electronic device. The plaintext cipher encryption method provided in this embodiment includes the following steps:

step S101, a plaintext password input by a user is acquired.

In this embodiment, the user input mode may be a keyboard input mode, a voice input mode, or the like of the electronic device, which is not limited in this embodiment.

In this embodiment, the plaintext password, i.e. the password commonly used by the user, includes digits 0-9, english letter case, special symbol, etc., and has a simpler structure.

Step S102, determining the mapping relation between each character in the plaintext password and the elements in the periodic table of the elements stored in the encryption database according to the plaintext password and the preset encryption database.

In this embodiment, the encryption database stores the mapping relationship between each character in the plaintext password and the element in the periodic table of elements stored in the encryption database. Meanwhile, each character of the plaintext password corresponds to each element, for example, when the plaintext password is 12345, the corresponding HHeLiBeB may be HHeLiBeB, that is, hydrogen helium lithium beryllium boron, and each number corresponds to an element. 1 corresponds to H,2 corresponds to He,3 corresponds to Li,4 corresponds to Be, and 5 corresponds to B. The mapping relationship between each character and each element of the plaintext password may be set according to actual requirements, which is not limited in this embodiment.

Step S103, determining a target password according to the mapping relation and the plaintext password.

In this embodiment, after determining the mapping relationship between each character and each element of the plaintext password, the target password may be determined according to the mapping relationship and the plaintext password.

Step S104, outputting the target password.

In this embodiment, the output of the target password may be output to an electronic device corresponding to the next process, for example, an electronic device corresponding to a decryption process of the target password.

The embodiment of the invention provides a plaintext cipher encryption method, which comprises the following steps: and acquiring a plaintext password input by a user. And determining the mapping relation between each character in the plaintext password and the elements in the periodic table of the elements stored in the encryption database according to the plaintext password and the preset encryption database. And determining the target password according to the mapping relation and the plaintext password. And outputting the target password. According to the plaintext password encryption method, firstly, the plaintext password input by a user is obtained, and then the mapping relation between each character in the plaintext password and the elements in the periodic table of the elements stored in the encryption database is determined by combining the preset encryption database with the plaintext password. Therefore, the plaintext password can be converted into the target password through the mapping relation, and meanwhile, as the target password corresponds to each element of the periodic table of elements, when other people crack the target password, the meaning of each character in the target password is difficult to crack, and compared with the current common plaintext password encryption mode, the safety is higher.

Fig. 3 is a flowchart of a plaintext cipher encryption method according to a second embodiment of the present invention, as shown in fig. 3, where each step of the plaintext cipher encryption method according to the present invention is further refined based on the plaintext cipher encryption method according to the previous embodiment of the present invention. The plaintext cipher encryption method provided in this embodiment includes the following steps.

Step S201, a plaintext password input by a user is acquired.

In this embodiment, the implementation manner of step 201 is similar to that of step 101 in the previous embodiment of the present invention, and will not be described in detail here.

It should be noted that, four mapping relations are stored in the encryption database according to four seasons of the year. The four mapping relations are the corresponding mapping relations between each character and elements in the plaintext password.

It should be noted that steps 202-203 are further refinements to step 102.

Step S202, the time of inputting the plaintext password by the user is obtained, and corresponding season information is determined according to the time.

In this embodiment, since four mapping relations are stored in the encryption database according to four seasons of a year, when a user inputs a plaintext password, the time when the user inputs the plaintext password can be obtained, so that corresponding season information is determined according to the time. For example, the time for inputting the plaintext password by the user is 1 month and 11 days, the time is winter, the determined season information is winter season, and meanwhile, the fourth mapping relation in the encrypted database is corresponding.

In this embodiment, the four mapping relationships may be the first spring-sequential mapping relationship, that is, the characters of the plaintext password correspond to the element sequences in the periodic table of elements according to the normal sequence of numbers, uppercase English, lowercase English, and special symbols. For example, 0 corresponds to H in the periodic table, 1 corresponds to He in the periodic table, and 2 corresponds to Li in the periodic table. The second summer is the up-down exchange sequence mapping relation. That is, the characters of the plaintext password correspond to the sequence of up-down interchange of elements in the periodic table of elements according to the normal sequence of numbers, uppercase English, lowercase English and special symbols. For example, 0 corresponds to He in the periodic table, 1 corresponds to H in the periodic table, 2 corresponds to Be in the periodic table, and 3 corresponds to Li in the periodic table. In the third autumn, the sequence mapping relation of the dislocation interchange is that the characters of the plaintext password correspond to the sequence of the dislocation interchange of the elements in the periodic table of the elements according to the normal sequence of numbers, english uppercase, english lowercase and special symbols. For example, 0 corresponds to Li in the periodic table, 1 corresponds to Be in the periodic table, 2 corresponds to H in the periodic table, and 3 corresponds to He in the periodic table. And in the third winter, the sequence mapping relation of head-to-tail exchange, namely, the characters of the plaintext password correspond to the sequence of head-to-tail exchange of elements in the periodic table of elements according to the normal sequence of numbers, english uppercase, english lowercase and special symbols. For example, 0 corresponds to Uuo of the last bit in the periodic table, 1 corresponds to Uus of the second to last bit in the periodic table, and 2 corresponds to Lv of the third to last bit in the periodic table. By adding four mapping relations corresponding to four seasons, the security of the plaintext password can be further improved.

Step S203, according to the corresponding season information, the mapping relation between each character in the corresponding kind of plaintext password and the elements in the periodic table of the elements stored in the encryption database is obtained from the preset encryption database.

In this embodiment, four mapping relations are stored in the encryption database according to four seasons of a year, and at the same time, the corresponding season information corresponds to the mapping relations, so that the corresponding mapping relations can be determined through the corresponding season information.

It should be noted that steps 204-206 are further refinements to step 103.

Step S204, determining the element password according to the mapping relation and the plaintext password.

In this embodiment, the element password refers to a password composed entirely of elements, such as HHeLiBeB.

Step S205, determining the season flag symbol according to the corresponding season information.

In this embodiment, the season flag symbol refers to a flag symbol corresponding to seasons, for example, the season flag symbol of four seasons may be 1 to 4.

Step S206, splicing the element password and the season mark symbol through a first preset splice symbol, and determining the spliced password as a target password.

In this embodiment, the first preset splice is used to separate the element password from the season flag symbol, and the first preset splice may be a special symbol. The target password for the final splice completion contains the element password, the first preset splice symbol and the season flag symbol, such as HHELiBeB-! 3, wherein HHELiBeB is the element cryptographic part, ++! And 3 is a season mark symbol, which corresponds to the third season, namely autumn.

Step S207, outputting the target password.

In this embodiment, the implementation of step 207 is similar to the implementation of step 104 in the previous embodiment of the present invention, and will not be described in detail here.

According to the plaintext cipher encryption method provided by the embodiment of the invention, the mapping relation between each character in four plaintext ciphers corresponding to four seasons and elements in the periodic table of elements stored in the encryption database is constructed. When the user inputs the plaintext password, the time of inputting the plaintext password by the user is correspondingly acquired, so that the corresponding season is judged according to the time, and the corresponding mapping relation is acquired. Therefore, the finally generated target password can change according to the time change of the plaintext password input by the user, and the same plaintext password can become different target passwords after being encrypted at different times, so that the success rate of cracking by other people is reduced, and the safety of the plaintext password is improved.

Fig. 4 is a flowchart of a plaintext cipher encryption method according to a third embodiment of the present invention. As shown in fig. 4, the plaintext cipher encryption method according to the present embodiment is further refined based on the plaintext cipher encryption method according to the previous embodiment of the present invention. The plaintext cipher encryption method provided in this embodiment includes the following steps.

Step S301, a plaintext password input by a user is acquired.

In this embodiment, the implementation manner of step 301 is similar to that of step 101 in the previous embodiment of the present invention, and will not be described in detail here.

It should be noted that, the encryption database is associated with the element type and the element type mark corresponding to the storage element.

Step S302, determining the mapping relation between each character in the plaintext password and the elements in the periodic table of the elements stored in the encryption database according to the plaintext password and the preset encryption database.

In this embodiment, the implementation manner of step 302 is similar to that of step 102 in the previous embodiment of the present invention, and will not be described in detail here.

Step S303, determining the element password according to the mapping relation and the plaintext password.

In this embodiment, the element password refers to a password composed entirely of elements, such as HHeLiBeN.

Step S304, determining the element type with the most elements in the element password according to the element password and the element type in the encryption database.

In this embodiment, since the element type and the element type flag corresponding to the element are stored in the encryption database in an associated manner, the element type and the element type flag corresponding to the element can be used to enhance the password security.

In this embodiment, the element type with the largest element in the element code, for example, the HHeLiBeN element code, where H belongs to a nonmetal, he belongs to an inert gas, li belongs to an alkali metal, be belongs to an alkaline earth metal, and N belongs to a nonmetal. The element type with the largest number of elements is nonmetallic and the corresponding element type label is a nonmetallic corresponding element type label.

Step S305, determining the corresponding element type mark in the encryption database according to the element type with the most elements.

In this embodiment, the element type marks and the element types are in one-to-one correspondence, and may be set according to actual requirements, which is not limited in this embodiment.

Step S306, the element password and the element type mark are spliced, and the spliced element password is determined to be a target password.

In this embodiment, the spliced target password includes an element password and an element type tag, such as HHeLiBeN7, where HHeLiBeN is an element password portion and 7 is an element type tag portion.

Optionally, in this embodiment, the splicing element password and the element type tag includes:

In this embodiment, the second preset splice is used to separate the element password from the element type tag. The spliced target password comprises an element password, a second preset splice and an element type mark, such as HHELiBeN@K7, wherein HHELiBeN is an element password part, @is the second preset splice, and K7 is an element type mark part.

Step S307, the target password is output.

In this embodiment, the implementation manner of step 307 is similar to that of step 104 in the previous embodiment of the present invention, and will not be described in detail here.

According to the encryption method for the plaintext password, the element type mark is added to the target password, so that the security of the target password is improved. When a user inputs a plaintext password, the element type with the most elements corresponding to the elements can be determined from the element password generated by mapping, the element type corresponds to the element type mark, and the element type mark is added in the formed target password, so that the success rate of cracking by other people is reduced, and the safety of the plaintext password is improved.

Fig. 5 is a detailed flowchart of step 306 of the plaintext cipher encryption method according to the third embodiment of the present invention. As shown in fig. 5, the plaintext cipher encryption method according to the present embodiment is further refined in step 306 based on the plaintext cipher encryption method according to the previous embodiment of the present invention. The plaintext cipher encryption method provided in this embodiment includes the following steps.

The encryption database is also used for storing the mapping relation between the element type mark and the chemical reaction formula and the mark corresponding to the chemical reaction formula in an associated mode.

Step S3061, the element password and the element type mark are spliced, and corresponding identifications in the encryption database are determined according to the element type mark.

In this embodiment, the mapping relationship between the element type mark and the chemical reaction formula and the identifier corresponding to the chemical reaction formula are also stored in the encryption database in an associated manner.

As shown in fig. 7, the method for decrypting the plaintext password according to the present embodiment further refines each step on the basis of the method for decrypting the plaintext password according to the previous embodiment of the present invention. The plaintext password decryption method provided by the embodiment comprises the following steps:

it should be noted that the encrypted identification information includes a first preset splice symbol and a season flag symbol.

The plaintext password decryption method provided in this embodiment may decrypt the target password in the method embodiment shown in fig. 2-3, and its implementation principle and technical effects are similar to those in the method embodiment shown in fig. 2-3, and will not be described in detail herein.

Meanwhile, in order to better understand the plaintext cipher encryption and decryption method of the present embodiment, the following describes in detail the construction of a database and the related flow of plaintext cipher encryption and decryption in the plaintext cipher encryption and decryption method. As shown in fig. 8 to 14, first, the mapping relation between each character of the plaintext password and each element in the periodic table of elements is constructed. As shown in fig. 8, the numbers 0-9 correspond to Li, be, na, mg, K, ca, rb, sr, cs, ba in sequence, and meanwhile, the mapping relationship can be increased by three mapping modes according to a seasonal mode, such as a mapping mode of up-down interchange of elements in the second quarter, a mapping mode of misplacement interchange of elements in the third quarter, and a mode of head-tail interchange of elements in the fourth quarter. The second summer is a sequential mapping relationship with up-down exchange. That is, the characters of the plaintext password correspond to the sequence of up-down interchange of elements in the periodic table of elements according to the normal sequence of numbers, uppercase English, lowercase English and special symbols. For example, 0 corresponds to He in the periodic table, 1 corresponds to H in the periodic table, 2 corresponds to Be in the periodic table, and 3 corresponds to Li in the periodic table. In the third autumn, the sequence mapping relation of the dislocation interchange is that the characters of the plaintext password correspond to the sequence of the dislocation interchange of the elements in the periodic table of the elements according to the normal sequence of numbers, english uppercase, english lowercase and special symbols. For example, 0 corresponds to Li in the periodic table, 1 corresponds to Be in the periodic table, 2 corresponds to H in the periodic table, and 3 corresponds to He in the periodic table. And in the third winter, the sequence mapping relation of head-to-tail exchange, namely, the characters of the plaintext password correspond to the sequence of head-to-tail exchange of elements in the periodic table of elements according to the normal sequence of numbers, english uppercase, english lowercase and special symbols. For example, 0 corresponds to Uuo of the last bit in the periodic table, 1 corresponds to Uus of the second to last bit in the periodic table, and 2 corresponds to Lv of the third to last bit in the periodic table. By adding four mapping relations corresponding to four seasons, the security of the plaintext password can be further improved.

Meanwhile, when the encrypted database is constructed, element categories and corresponding element category labels, that is, element categories and labels as shown in fig. 9, are also stored. Wherein the element category includes main group metals, metalloids, non-metals, halogens, inert gases, alkali metals, alkaline earth metals, lanthanides, actinides. The element class labels correspond to K1-K9, respectively.

After the mapping relation between each character of the plaintext password and each element in the periodic table of elements is constructed, the association between the element and the element category is completed, as shown in fig. 10. And then, continuing to construct the corresponding relation between the chemical reaction formula and the mark and the element type mark. As shown in fig. 11, id is the identification. Each label corresponds to a chemical reaction, and each label corresponds to an element type label. The reactant colors in the figures may be used later in order to continue to enhance the target password, which will not be described in detail in this example.

After the encryption database is built, the plaintext password input by the user can be acquired to carry out targeted encryption and decryption. As shown in fig. 12-14, three levels of encryption, respectively. Fig. 12 is a first level of encryption, i.e., enhanced encryption using mapping relationships of four seasons without using element categories and chemical equations. As shown in FIG. 12, test 1332-! The plaintext cipher @ T1 becomes PaFSePaMgBeBeBeLiTlPbPaMg-! 3, wherein PaFSePaMgBeBeBeLiTlPbPaMg is the element code part, |! For the first preset splice, 3 refers to a seasonal marker symbol. Fig. 13 is a second level of encryption, i.e., mapping relationships and element categories for four seasons are used, but no enhanced encryption using chemical equations is used. As shown in FIG. 13, test 1332-! The plaintext cipher @ T1 becomes PaFSePaMgBeBeBeLiTlPbPaMg-! 30K7, wherein PaFSePaMgBeBeBeLiTlPbPaMg is an element code part, |! For the first preset splice, 3 refers to a season flag symbol, 0 is a second preset splice, K7 is an element type flag representing alkaline earth metal, and fig. 14 shows a third-level encryption level, that is, enhanced encryption using mapping relationships of four seasons, element categories, and chemical formulas. As shown in FIG. 14, test 1332-! The plaintext cipher @ T1 becomes PaFSePaMgBeBeBeLiTlPbPaMg-! 30K7@O2K0KO2, wherein PaFSePaMgBeBeBeLiTlPbPaMg is the element code part, I! For the first preset splice, 3 refers to a seasonal tag symbol, 0 is a second preset splice, K7 is an element type tag representing alkaline earth metal, @ is a third preset splice, and O2K0KO2 is a chemical reaction formula.

Meanwhile, the encryption mode corresponding to the encryption level may be set according to the actual requirement, which is not limited in this embodiment. In decryption, the target password can be decrypted in a targeted manner according to the encrypted identification information, namely the first preset splicer, the second preset splicer and the third preset splicer, and the decryption result is shown in fig. 12-14. The password, namely the plaintext password, and the element main attribute and the chemical reaction formula can also be used for multiple times of verification when a user inputs the plaintext password to acquire file data, for example, the password is in a picture form, so that the user can perform multiple times of verification by clicking a correct picture, and the safety of the file data is improved.
