a method for encrypting and hiding information based on language grammar includes following steps:

step 1, designing a grammar rule dictionary of the language, summarizing rules of the language to obtain a total rule and a sub-rule, recording a set of the total rule and the sub-rule as M, and recording each rule M in the set_iCan be expressed as M ═ M_iI 1.. n, where the rules include both the transformation relation of the syntax and the terminator as a leaf of the syntax tree, and each overall rule corresponds to one block of the binary string to be encrypted.

And 2, designing Hash mapping based on the key. The length of the key M is consistent with the number of the total rules, and the rule number j of the total rules in the initial state directly corresponds to the binary string S_jThe number n being converted into a decimal number, i.e. a binary string S_jMapping on rule j, the ASCII code value x of j-th bit character of key M represents the number of backward-shifted bits of rule j, if the position is mapped, the backward shift is continued in turn until an unmapped position is found, and the process is recorded to shift d bits backward, at which time the binary string S_jIt is mapped onto rule j + n + d.

And 3, converting the file to be encrypted into a binary string to be encrypted, recording the binary string to be encrypted as B, decomposing the binary string to be encrypted into m groups, wherein m is the length/l of B, and the set of groups with scores being C. Traversing the set C through the Hash mapping obtained in the step 2, and finding out the rule M corresponding to each group of binary strings_xThen according to rule M_xA sentence is generated.

Detailed Description

The present invention is further illustrated by the following description in conjunction with the accompanying drawings and the specific embodiments, it is to be understood that these examples are given solely for the purpose of illustration and are not intended as a definition of the limits of the invention, since various equivalent modifications will occur to those skilled in the art upon reading the present invention and fall within the limits of the appended claims.

Step 3, converting the file to be encrypted into a binary string to be encrypted, marking the binary string to be encrypted as B, and decomposing the binary string to be encrypted into m groups, wherein m is the length/l of B, or m is the length/l of B

Is grouped for one group, and the set of groups scored is C. Traversing the set C through the Hash mapping obtained in the step 2, and finding out the rule M corresponding to each group of binary strings_xThen according to rule M_xA sentence is generated.

And traversing the set C, using each binary string in the set C to obtain a corresponding rule according to Hash mapping to generate sentences, and splicing the sentences together, wherein the spliced sentences are encrypted ciphertexts. Concatenation is the addition of periods or exclamation marks or question marks between sentences as delimiters for the sentences.

The method for generating the statement by the rule is as follows: extending backward from the starting sentence of the grammar, taking any one by random method if the relation is 'OR', and adding the character string generated by the generating formula to the rear of the character string generated in the last stage if the relation is 'AND'.

The rule is H: x | Y + Z, where H represents the starting sentence, X, Y, Z are production formulas, and' represents or has a priority greater than and, where X: "x", Y: "y", Z: "z", the string acts as a terminator and the sentence generated by this rule may be either "ac" or "bc".

The ciphertext generation algorithm is mathematically explained as follows: first we will design a formal language grammar without ambiguity, and let the language described by grammar G ═ N, (Σ, P, S) be as follows:

N＝{S，A，B，C，D}；

∑＝{a，b，c}；

P：(1)S->A|B|C|D

(2)A->aAc|ac

(3)B->bBa|ba

(4)C->cCd|cd

(5)D->dDa|da

of course we can only design the starting sentence S of this grammar to be of the form S- > a | B | C | …, where a, B, C represent different arguments.

Here we do several conventions, we call all the arguments that appear after the start sentence S a rule dictionary, and we call one rule for each argument. The following is the specific content of the encryption algorithm:

inputting: rule dictionary, binary stream of content to be encrypted

And (3) outputting: encrypted ciphertext

Description of algorithm content:

a. dividing each n bits of the plaintext data stream into a group, wherein n satisfies an expression 2^ n ═ X, and X is the number of rules in the rule dictionary. Let i be 0 and note that the number of groups into which the plaintext is divided is N.

b. Calculating the decimal number m corresponding to the n bits of the ith group

c. And taking out the (m + 1) th rule according to the rule sequence in the rule dictionary, and randomly generating a non-empty character string S according to the rule.

d. The string S is added to the ciphertext last.

e. If i is equal to N, outputting the ciphertext, otherwise, i is i +1 and returns to b

A simple demonstration will be given below of how plaintext is encrypted to ciphertext. Assuming the plaintext is a binary string 00011011, encryption is performed using grammar G described above.

1. Divide the binary string into 4 groups, 00, 01, 10, 11 respectively

2. Calculate the first set of values as 0, corresponding to rule A1, and randomly generate the string "aacc"

3. The second set of numbers is calculated as 1, corresponding to rule B2, and the string "ba" is randomly generated "

4. Calculate the number of the third group as 2, corresponding to rule C3, and randomly generate the string "cccdd"

5. Calculate the number of the fourth group as 3, corresponding to the 4 th rule D, and randomly generate the string "ddddaaa"

6. The ciphertext aaccbaccddddddaaa is output.

Inputting: rule dictionary, ciphertext content

And (3) outputting: plaintext before encryption

Description of algorithm content:

a. inputting ciphertext character string S

b. Finding a continuous substring from S initial character to match a rule, and recording the order of the matchable rule in the rule dictionary as m

c. Converting m-1 into binary string, adding to plaintext

d. Removing the matchable substrings from S, returning to b if the length of S is not 0, otherwise, outputting the plaintext

A simple demonstration is given below of how to change from ciphertext to plaintext. Assuming that the ciphertext is aaccbaccc ddddddaaaa, decryption is performed using the above-described grammar G.

1. Let S be aaccbaccdddddddaaaaa

2. Using automaton grammar analysis to obtain aacc matching rule A, and obtaining the order m of A as 1

3. Converting m-1 to binary string of 00, and removing the matching string from S to obtain bacccddddddaaaa

4. Using automaton analysis to obtain ba matching rule B, obtaining the order m of B as 2, converting m-1 into binary string as 01, and obtaining cccdddddddaaa after removing matching string from S

5. Using automaton to analyze to obtain cccddd matching rule C, obtaining the order m of C as 3, converting m-1 into binary string as 10, and removing the matching string from S to obtain dddaaa

6. Using automaton analysis to obtain dddaaa matching rule D, obtaining the order m of D as 4, converting m-1 into binary string as 11, and removing the matching string from S to be null

7. The output plaintext is 00011011

Algorithmic encryption performance analysis

According to the kerckoffs theorem, the security of a cryptographic algorithm should not depend on the algorithm but on the key, which is publicly available. The algorithm conforms to the theorem, because the grammar analysis is the content of the automaton and is already public, and the key in the algorithm is the rule dictionary established by the user.

When the algorithm is used for encryption, the length of an input binary string is assumed to be n, the number of groups is assumed to be m, the number of rules is assumed to be C1, each rule randomly generates a character string, and the character string is subjected to argument conversion of C2 times, so that m is n/log₂C1, time complexity of encryption is 0(C2 x n/log)₂C1) C1 and C2 may be considered as constants with respect to n, so the temporal complexity of encryption is 0 (n).

When the algorithm is used for decryption, the input ciphertext is assumed to contain n rules, the automaton is used for analyzing by a backtracking method, when the rules are properly set, the heuristic can be terminated for an incorrect rule heuristic constant C1 times, the average consumed time for matching a correct rule is m (m is the average argument number from a rule to a character string), and the total number of the rules in the rule dictionary is assumed to be C2. The worst time complexity for completing decryption is therefore 0(n (C1 (C2-1) + m)), while C1, C2, m are all constants with respect to n, so the time complexity for decryption can also be approximated to 0 (n).

When the algorithm is attacked, although the ciphertext generated by the algorithm is a Chinese text, the attacker cannot obtain the replacement rule by using frequency analysis, because the content of the terminal symbols can be obtained only by using the frequency analysis, and the terminal symbols can appear in each rule in a staggered mode. If brute force cracking is adopted, under the condition that the number of the rules is 256, the complexity of the rule sorting of the grammar is 256! The probability of a character string that can be generated for a grammar with a recursive structure can also be a very large value, which tends to be infinite theoretically regardless of other factors, and the product of the two values is far greater than the processing power of modern computers.

Examples of the invention

1. Both communication parties exchange and confirm in advance to use the same rule dictionary.

2. And transmitting the information to be encrypted and the secret key into an encryption program to generate a ciphertext.

3. And transmitting the ciphertext to the other party through a network or other forms.

4. And after receiving the information, the opposite side transmits the key and the ciphertext into a decryption program to obtain the ciphertext.

Compared with the white language, the language has the advantages of being short and difficult to understand. Like a greeting sentence, the white language may be as long as more than 10 characters, but two or three characters of the language sentence are completed, so that the information embedding rate can be effectively improved. Meanwhile, the language has the characteristic of difficult understanding, and the defect of poor logicality among paragraphs can be covered by utilizing the advantages of the language. Designing a language grammar rule dictionary, summarizing rules of the language texts flowing to the present by a method of combining manual division and machine division, and finally obtaining 256 total rules and 838 sub-rules, wherein the selection of the total rules and the sub-rules is related to the complexity of encryption: 500 bibliographic rules are extracted from the famous literature of the literature such as the poetry, the stethography, the compendium of herbs, the Zhouyi and the like, and 256 rules are selected from the 500 rules and optimized.

As shown in FIG. 1, the file to be encrypted is first converted into a binary string, which is denoted as B, andinputting a rule set D used for encryption, wherein the rule D is a preset dialect rule set, and inputting an encryption key M. The key M is used to calculate the mapping relationship between each element in the rule set D and the binary string to be encrypted, and the specific calculation method is illustrated in FIG. 3, where it is assumed that each rule D in the rule set D is_iAll and binary string S_jCorrespond to each S_jTheir binary strings are always equal in length, and are recorded as l (here, it is ensured that the rule can cover all binary strings of length l, i.e. any binary string of length l can always find a rule to map with. And decomposing the binary string B into m groups, wherein m is the length/l of B, and the set of the scored groups is C. Traversing the set C, generating sentences by using the rule corresponding to each binary string in the set C, and splicing the sentences together (the splicing is to add a sentence mark or an exclamation mark or a question mark between the sentences as a separator of the sentences), wherein the spliced sentences are encrypted ciphertext. The method for generating the statement by the rule is as follows: extending backward from the starting sentence of the grammar, taking any one by random if it is "or" relation, adding the character string generated by this generating formula to the rear of the character string generated in the previous stage if it is "and" relation, for example, there is a rule of S: a | B + C (where S is specified to represent the starting sentence, A, B, C are production formulas, and' represents or has a priority greater than AND, where A: "a", B: "B", C: "C", the string acts as a terminator), so the sentence generated by this rule may be "ac" or "bc".

As shown in fig. 2, we first input a binary string E of ciphertext, a key K, and a rule dictionary D. And calculating the mapping relation between each element in the rule set D and the binary string to be encrypted by using K, wherein a specific calculation method is illustrated in the attached figure 3. The ciphertext is divided into single sentences according to the separators, the rules corresponding to each sentence are analyzed through a push-down automaton, the corresponding binary mapping is found, the binary strings are spliced in sequence and written into a file, and the plaintext before encryption is obtained.

As shown in FIG. 3, a rule dictionary D and a binary are calculated by a secret keyAnd (5) making a flow chart of the corresponding rule. Firstly, inputting a key K and a rule set D, ensuring that the element number of the rule set D is the same as the length of the key K, and recording as m. First we apply to each rule D in the rule set D_iCorresponding to a binary string of decimal value i (e.g. D)₂Corresponding to binary string "10"), and then traverse each element of rule D, the ith newly mapped binary string B_iThe following conditions are satisfied: b is_iHas a decimal value of i + K_iIn which K is_iThe ACSII code for the ith character in the key is incremented by 1 if the decimal number has already been mapped until it is mapped to an unmapped number.

The hiding algorithm is used for hiding, and the ciphertext text generated when the information To be encrypted is "To be, or not To be-that is a request," is shown in fig. 4 (where the line wrapping is manually added for the convenience of viewing). It can be seen that the result encrypted using the language conforms to the normal language grammar, is difficult to recognize as a machine-generated statement, and is very confusing. Meanwhile, the field to be encrypted is 39 bytes, and the encrypted text is only 251 bytes (containing no line feed), and the embedding rate is as high as 15.53%.

As shown in FIG. 5, using both NiceText and T-lex concealment "To be, or not To be-that is a query.", we find that the embedding rate of NiceText is around 1.8%, and T-lex is only 0.52%, while our grammatical concealment embedding rate is around 15.5%. Fig. 5 is a graph comparing embedding rates. Therefore, the invention has the following beneficial effects:

1. compared with the traditional information hiding method, such as a T-lex system and a Nicetext system, the method hides through text styles, improves the information embedding rate to about 15%, and only 1.8% and only 0.52% of T-lex are adopted in the Nicetext method.

2. In the case of 256 rules, the computation complexity of the algorithm encrypted ciphertext through brute force cracking is more than 8 x 10^507, and the AES encrypted brute force cracking complexity of the 256-bit length key is about 10^ 75.

3. Compared with the traditional information hiding method, the method has the advantages that the characteristics that the Chinese language is difficult to understand and the context jumping property is large are utilized, the defect that the meaning difference between the generated text information hiding sentences is large is overcome, and the method has better hiding property compared with the traditional information hiding method.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.

Claims

1. A method for encrypting and hiding information based on language grammar is characterized by comprising the following steps:

step 1, designing a grammar rule dictionary of the language, summarizing rules of the language to obtain a total rule and a sub-rule, recording a set of the total rule and the sub-rule as M, and recording each rule M in the set_iExpressed as M ═ M_iN, wherein the rules include both the transformation relation of the syntax and the terminator as the leaves of the syntax tree, and each overall rule corresponds to a block of the binary string to be encrypted;

step 2, designing Hash mapping based on a secret key; the length of the key M' is consistent with the number of the total rules, and the rule number j of the total rules in the initial state directly corresponds to the binary string S_jThe number n being converted into a decimal number, i.e. a binary string S_jMapping to rule j, the ASCII code value x of the j-th character of key M' represents the number of backward-shifted bits of rule j, if the position is mapped, the backward shift is continued in turn until an unmapped position is found, and the process is recorded as a backward shift by d bits, at which time the binary string S is_jIt is mapped to rule j + n + d;

step 3, converting the file to be encrypted into a binary string to be encrypted, recording the binary string to be encrypted as B, decomposing the binary string to be encrypted into m groups, wherein m is the length/l of B, and the set of groups with scores being C; traversing the set C through the Hash mapping obtained in the step 2, and finding out the rule M corresponding to each group of binary strings_xThen according to rule M_xGenerating a sentence;

traversing the set C, using each binary string in the set C to obtain a corresponding rule generation statement according to Hash mapping, and splicing the statements together, wherein the spliced statement is an encrypted ciphertext; the splicing is that periods or exclamation marks or question marks are added between sentences to be used as separators of the sentences;

the method for generating the statement by the rule is as follows: extending backward from the starting sentence of the grammar, taking any one of the relations by random method if the relation is 'OR', and adding the character string generated by the generating formula to the rear of the character string generated in the last stage if the relation is 'AND';

the rule is H X Y + Z, wherein H represents the starting sentence, X, Y, Z are the generating formulas, and the priority of the generating formulas is greater than AND, wherein X: "X", Y: "Y", Z: "Z", and the character string serves as the terminator;

the language described by grammar G ═ N, Σ, P, S) is specifically as follows:

N＝{S,A,B,C,D}；

∑＝{a,b,c,d}；

P:(1)S->A|B|C|D

(2)A->aAc|ac

(3)B->bBa|ba

(4)C->cCd|cd

(5)D->dDa|da

the starting sentence S can only be of the form S- > a | B | C | …, a, B, C representing different arguments.
