Referring to an application scenario diagram shown in fig. 1, fig. 1 includes an electronic device 10 that executes the encrypted communication method disclosed in the embodiment of the present invention, and the electronic device 10 is connected to a plurality of other electronic devices 20 (for example, a mobile phone, a smart television, a vehicle-mounted terminal, and the like) through a network and is capable of receiving password information transmitted by the plurality of other electronic devices 20.
Referring to a work flow diagram shown in fig. 2, an encrypted communication method disclosed in the embodiment of the present invention includes the following steps:
and step S11, acquiring one or more password information used in each preset time period.
In the encryption communication method disclosed by the embodiment of the invention, encryption is carried out on the received password information at intervals of a preset time period.
The specific duration of the preset time period may be set according to actual requirements, which is not limited in the embodiments of the present invention. For example, the preset time period may be one week. Generally, the higher the safety requirement, the shorter the specific duration of the preset time period.
Step S12, counting the occurrence frequency of each character included in the one or more password information, and obtaining the code value corresponding to each character according to the occurrence frequency of each character.
The electronic equipment executing the encryption communication method disclosed by the embodiment of the invention can acquire the password information of a plurality of electronic equipment connected with the electronic equipment through a network. Each password information is composed of characters, so that the times of the characters in each password information can be accumulated, and the total times of the characters can be obtained.
And step S13, determining the code value corresponding to each character appearing in the password information needing to be encrypted, splicing the code value corresponding to each character according to the appearance sequence of each character in the password information, and determining the encryption result according to the splicing result.
In this step, the coded value corresponding to each character is spliced according to the occurrence order of each character, that is, if a certain character is located at the nth bit in the password information, that is, the occurrence order of the character is N, in this case, during splicing, the coded value corresponding to the character is also located at the nth bit. Wherein N is a positive integer.
And step S14, storing the encryption result.
The embodiment of the invention discloses an encryption communication method, in the method disclosed by the embodiment of the invention, password information is encrypted once every a preset time period, in addition, in the encryption process, the code value corresponding to each character is determined according to the occurrence frequency of each character, and because the acquired password information is not fixed in each time period, the occurrence frequency of each character is not fixed, correspondingly, the code value corresponding to each character is also not fixed, therefore, the splicing result of splicing the code values is not fixed, and the acquired encryption result also changes along with the time period. That is to say, the method disclosed by the embodiment of the invention is used for encrypting the password information, and the obtained encryption result changes periodically, so that the password information is not easy to crack, and the problems of great risk and low safety of the encryption method adopted by the prior art are solved.
As a refinement of the method of fig. 2, in another embodiment of the present invention, as shown in fig. 3, the step S12 of counting the occurrence number of each character included in the one or more pieces of password information and obtaining the encoded value corresponding to each character according to the occurrence number of each character generally includes the following steps:
step S121, after counting the occurrence frequency of each character included in the one or more pieces of password information, sorting each character according to the occurrence frequency of each character.
For example, each character may be sorted by the number of times it occurs, from large to small.
And step S122, performing binary-heap coding on each character according to the sequencing result, and acquiring a coding value corresponding to each character according to the coding result.
By the scheme from step S121 to step S122, the encoding value corresponding to each character can be acquired according to the binary heap encoding mode.
Further, the binary-heap coding is performed on each character according to the sorting result, and a coding value corresponding to each character is obtained through the coding result, including the following steps:
firstly, according to the sorting result, maximum pile coding is carried out on each character.
Each node of the maximum heap formed by encoding is the character, the root node is the character with the most occurrence times, two child nodes of each father node are respectively the characters with the occurrence times which are only inferior to the two characters with the occurrence times of the father node, the characters with more occurrence times in the two child nodes are the children on the left side of the father node, the characters with less occurrence times in the two child nodes are the children on the right side of the father node, the key value of the root node is 1, the key value of each child node on the left side is 0, and the key value of each child node on the right side is 1.
And then, determining the code value corresponding to each character according to the maximum heap and the key value of the node corresponding to each character.
In the above scheme, the code value corresponding to each character can be obtained by maximum heap coding in the binary heap.
To elaborate how to obtain the encoding value corresponding to each character according to the maximum pile encoding, the following description is made by an example.
In this example, it is assumed that, after counting the number of occurrences of each character included in each password information by step S12, it is determined that a is 100 times in total, b is 80 times in total, C is 50 times in total, D is 20 times in total, f is 16 times in total, 8 is 12 times in total, and 3 is 10 times in total.
In this case, the maximum heap is constructed as shown in fig. 4, and since this character occurs the most frequently, a is the root node. Because two child nodes of each father node are respectively two characters with the occurrence frequency only second to the occurrence frequency of the father node, the character with more occurrence frequency in the two child nodes is the left child of the father node, the character with less occurrence frequency in the two child nodes is the right child of the father node, and a is taken as the father node, the two child nodes of a are respectively b and C, and because the occurrence frequency of b is more, the occurrence frequency of C is less, b is the left child of a, and C is the right child of a. Correspondingly, when b is taken as a parent node, two child nodes of b are respectively D and f, D is the left child of b, and f is the right child of b. Taking C as the parent, the two children nodes of C are 8 and 3, respectively, and 8 is the left child of C and 3 is the right child of C.
In addition, since the key value of the root node is 1, the key value of each left child node is 0, and the key value of each right child node is 1, the key value of the root node a is 1, the key value of b is 0, the key value of C is 1, the key value of D is 0, the key value of f is 1, the key value of 8 is 0, and the key value of 3 is 1.
According to the maximum heap and the key value of the node corresponding to each character, it can be determined that the code value corresponding to a is 1, the code value corresponding to b is 10, the code value corresponding to C is 11, the code value corresponding to D is 100, the code value corresponding to f is 101, the code value corresponding to 8 is 110, and the code value corresponding to 3 is 111.
In addition, in the encryption communication method disclosed in the embodiment of the present invention, a step of splicing the coded values corresponding to each character according to the occurrence order of each character in the password information and determining the encryption result according to the splicing result is also disclosed. In practical applications, the encryption result can be obtained in various ways.
In one mode, the determining an encryption result according to the splicing result includes:
after the splicing result is obtained, the splicing result is divided, wherein each divided group of codes comprises m numbers, 0 or 1 is supplemented in a group of codes which is less than the m numbers, m is a preset positive integer, and a character string formed by each divided group of codes containing the m numbers is determined as the encryption result.
For example, according to the above example, it is determined that a corresponds to a code value of 1, b corresponds to a code value of 10, C corresponds to a code value of 11, D corresponds to a code value of 100, f corresponds to a code value of 101, 8 corresponds to a code value of 110, and 3 corresponds to a code value of 111. In this case, if the password information to be encrypted is apdcbf 83, the concatenation result of the encoded value corresponding to each character in the password information after concatenation is 11001110101110111. Assuming that m is 4, a group of codes with less than m numbers is supplemented with 0, the splicing result is divided into 1,1001,1101,0111,0111, and since the number of the first group of codes is less than four, three 0 s are supplemented before the first group of codes, so that 0001,1001,1101,0111,0111 is obtained. 0001,1001,1101,0111,0111 is the encryption result.
Through the steps, the splicing result can be further processed to obtain an encryption result, the cracking difficulty is improved, and therefore the safety can be improved.
In another mode, the determining an encryption result according to the splicing result includes the following steps:
firstly, after a splicing result is obtained, the splicing result is divided, wherein each divided group of codes comprises 4 numbers, and 0 or 1 is supplemented in a group of codes with less than 4 numbers.
Then, each divided group of codes is converted into a 16-system code, the converted number of each group of codes is obtained, and a character string formed by the converted number of each group of codes is determined as the encryption result.
For example, in the above example, after obtaining 0001,1001,1101,0111,0111 groups of codes, each group may be converted into 16-ary code, so as to obtain 19b77, and the character string is the final encryption result.
Through the steps, the splicing result can be further processed to obtain an encryption result, the difficulty of cracking is improved, the safety can be improved, and in addition, each group of codes is respectively converted into a 16-system code, so the encryption result is simplified, and the occupation of a storage space is reduced.
