[0002] At present, the URLs of the details pages of certain types of data of many companies contain plain text numbers, such as http: / / XXX.test.com / id=123. Some external crawler software will use the above rules of web page URLs to crawl the data of the entire website in ascending order of ID, which brings challenges to the data security and service pressure of corporate websites. In the prior art, in response to this situation, mature signature algorithms and symmetric encryption algorithms are generally used to achieve encryption and symmetric decryption. However, the use of symmetric encryption algorithms requires the maintenance of keys on the one hand, and decryption consumes a large amount of machine resources on the other hand, which greatly increases the cost of maintaining corporate data security. Therefore, there is an urgent need for a technology that can provide lightweight encryption obfuscation for internal enterprise data for page-level anti-scraping worms. Summary of the invention

[0130] Exemplary Method 1

[0131] Figure 1 FIG. 1 is a flow chart of a webpage URL encryption method provided by an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as Figure 1 As shown, the following steps are included:

[0132] Step 101, obtaining the plaintext number to be encrypted in the URL of the web page to be encrypted.

[0133] Usually, the plaintext number is located at the end of the webpage URL. For example, when the webpage URL is http: / / XXX.test.com / id=123 or http: / / XXX.test.com / 123.html, the plaintext number to be encrypted extracted from the webpage URL is 123.

[0134] Figure 2 FIG. 1 is a schematic diagram of a webpage URL encryption process provided by an exemplary embodiment of the present invention. Figure 2 As shown, for a known webpage URL: http: / / XXX.test.com / id=123, its plaintext number m=123, in this example, the plaintext number 123 will be lightly obfuscated and encrypted according to the set ciphertext format.

[0135] Step 102: Generate ciphertext of ciphertext bits using a preset mapping function according to the plaintext digits.

[0136] Preferably, according to the plaintext digit, a preset mapping function is used to generate the ciphertext of the ciphertext bit, including:

[0137] Extract the number of each digit in the plaintext number, wherein the number of each digit is any natural number from 0 to 9;

[0138] Using a preset mapping function to map the numbers of each digit to obtain a mapping result of the numbers of each digit, wherein the mapping function is a function that maps 0 to 9 to characters respectively, and the mapping result of the numbers of each digit is a character string with a fixed length;

[0139] The mapping results of each digit are combined to generate the ciphertext of the ciphertext bit.

[0140] In one embodiment, a mapping function f(x) is preset, wherein x is a natural number 0-9, and the mapping function f(x) maps 0-9 to strings of fixed length, respectively, and the characters may include [0-9, az, AZ, ~! @#￥%……&*()]. Figure 2 The plaintext number m=123 in the number is 3 digits, and the numbers on each digit are 1, 2, and 3. Then the mapping function f(x) is used to map the numbers 1, 2, and 3 respectively. After obtaining the mapping results, they are combined to generate the ciphertext v41vmz4a93 of the ciphertext bit, and fill it to the 0-9 digits of the ciphertext bit. At this time, through Figure 2 It can be seen that bits 10-21 in the ciphertext are missing.

[0141] Step 103, according to the plaintext number and the ciphertext of the ciphertext bit, a preset gene extraction function is used to obtain a random filling strategy.

[0142] Preferably, according to the plaintext number and the ciphertext of the ciphertext bit, a preset gene extraction function is used to obtain a random filling strategy, including:

[0143] Extracting the number of each digit in the plaintext number;

[0144] According to the number of each digit, determine the length of the mapping result of the number of each digit based on the mapping function;

[0145] Determine the ciphertext length of the plaintext number according to the length of the mapping result of each digit;

[0146] Determine the ciphertext bit length according to the ciphertext length of the plaintext number and the preset ciphertext bit length;

[0147] The preset gene extraction function determines the random filling strategy according to the ciphertext bit pseudo-filling length, wherein the gene extraction function is a function that determines the corresponding relationship between the ciphertext bit pseudo-filling length and the random filling strategy, and the random filling strategy includes the ciphertext bit pseudo-filling length and the gene factor value of the gene information bit corresponding to the ciphertext bit pseudo-filling length.

[0148] Step 104: Generate interference values ​​of ciphertext bits and gene factor values ​​of gene information bits according to the random filling strategy.

[0149] Preferably, generating the interference value of the ciphertext bit and the gene factor value of the gene information bit according to the random filling strategy includes:

[0150] Based on the ciphertext bit pseudo-padding length in the random padding strategy, generate a random number equal to the length value of the ciphertext bit pseudo-padding length as a random interference value of the ciphertext bit;

[0151] The gene factor value of the gene information bit corresponding to the proposed filling length of the ciphertext bit in the random filling strategy is filled into the gene information bit.

[0152] In one embodiment, after the mapping function f(x) is established for the plaintext, in order to make the ciphertext complete, it is necessary to fill the vacant positions outside the ciphertext, and at the same time, it is necessary to effectively distinguish the ciphertext and the filled values. Therefore, this embodiment sets a gene extraction function g(f(x)). Figure 2 As shown, after extracting the numbers 1, 2 and 3 of each digit in the plaintext number, the length of the mapping results of the numbers 1, 2 and 3 is determined based on the mapping results of the mapping function f(x) for the numbers 1, 2 and 3, and the sum of them determines that the ciphertext length of the plaintext number 123 is 10 bits. Since the preset ciphertext length is 22 bits, it can be determined that the length of the ciphertext to be filled is 12 bits. When the length of the ciphertext to be filled is determined to be 12 bits, the gene extraction function can determine the random filling strategy corresponding to the ciphertext bit to be filled length according to the predetermined correspondence between the ciphertext length to be filled and the random filling strategy, and determine the gene factor value of the gene information bit corresponding to the ciphertext bit to be filled length from the random filling strategy. According to Figure 2 It can be seen that the present embodiment includes three gene information bits, 22 bits, 25 bits and 30 bits respectively, and their gene factor values ​​are 1, I and e respectively. For the 12 bits to be filled in the ciphertext bit, a 12-bit random number 637cb35rbdfb is randomly generated as an interference value. By using the gene extraction function to generate the gene factor, the ciphertext bit generated according to the mapping function can be self-explanatory.

[0153] Step 105: randomly generate a padding value for the padding bit.

[0154] In one embodiment, Figure 2 As shown, for the padding bits 23-24 and 26 to 29, random numbers be and fdvf are generated as padding values, respectively.

[0155] Step 106: Generate a signature value of the check digit using a signature function according to the plaintext number.

[0156] For the plaintext numbers to be encrypted in the obtained URL, a signature function can be pre-generated for signing to obtain the signature value of the check digit. The signature function can generate a value for each digit in the plaintext number, and then perform a comprehensive operation on each generated value to determine the signature value, or it can be an exhaustive enumeration of the plaintext numbers, and then generate a signature value for each plaintext number. The signature is mainly used to detect forgery. For example, the original plaintext number is signed to obtain a unique signature value for the check digit. Then, when the signature is verified during decryption, if it is found that the obtained check value is inconsistent with the signature value of the check digit in the encrypted ciphertext, it can be said that there is a counterfeit encryption behavior. From Figure 2 It can be seen that in this embodiment, when the plaintext number is 123, the signature value of the check digit generated by the signature function is 7.

[0157] Step 107, combining the gene factor value, padding value and signature value, as well as the ciphertext and interference value of the ciphertext bit to generate an encrypted ciphertext.

[0158] Preferably, the gene factor value, the padding value and the signature value, as well as the ciphertext and the interference value of the ciphertext bit are combined to generate an encrypted ciphertext, including:

[0159] Using the ciphertext and the interference value of the ciphertext bit as the first field;

[0160] Arrange the gene factor value and the filling value alternately as a second field;

[0161] Use the signature value as the third field;

[0162] The first field, the second field, and the third field are combined in order to generate an encrypted ciphertext.

[0163] In one embodiment, from Figure 2 It can be seen that the ciphertext bits are 0 to 21, which are used as the first field, the gene information bits are 22, 25 and 30, and the 23-24 and 26-29 bits as the filling bits are arranged alternately as the second field, and the check bit 31 is used as the third field.

[0169] The webpage URL encryption method described in this embodiment protects the security of internal enterprise data and prevents web crawlers from sequentially traversing and crawling URLs.

At the same time, it can also prevent attacks through self-signatures, which has the same technical effect as the prior art while greatly saving encryption and decryption costs.

[0170] Exemplary Method 2

[0171] Figure 3 FIG. 1 is a flow chart of a webpage URL decryption method provided by an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as Figure 3 As shown, the following steps are included:

[0172] In step 201, the encrypted ciphertext in the encrypted webpage URL is obtained.

[0173] In step 202, according to the gene factor value of the gene information bit in the encrypted ciphertext, a gene reverse restoration function is used to extract the ciphertext of the ciphertext bit.

[0174] Preferably, according to the gene factor value of the gene information bit in the encrypted ciphertext, the ciphertext of the ciphertext bit is extracted using a gene reverse restoration function, including:

[0175] According to the gene factor value of the gene information bit in the encrypted ciphertext, the gene reverse restoration function determines the ciphertext bit length to be discarded of the encrypted ciphertext, wherein the gene reverse restoration function is a function that determines the corresponding relationship between the gene factor value of the gene information bit and the ciphertext bit length to be discarded;

[0176] According to the proposed discarded length of ciphertext bits of the encrypted ciphertext and the preset length of the ciphertext bits, the ciphertext of the ciphertext bits is extracted from the encrypted ciphertext.

[0177] In step 203, a first plaintext number is obtained using a reverse mapping function according to the ciphertext of the ciphertext bit.

[0178] Preferably, according to the ciphertext of the ciphertext bit, using a reverse mapping function to obtain the first plaintext number comprises:

[0179] Mapping the ciphertext of the ciphertext bit using a reverse mapping function to determine the number of each digit in the first plaintext number, wherein the reverse mapping function is a function that maps a string of fixed length to any natural number from 0 to 9;

[0180] The numbers of each digit are combined in an order corresponding to the ciphertext of the ciphertext digit to generate a first plaintext number.

[0181] In step 204, a check value is generated using a signature function according to the first plaintext number.

[0182] In step 205, the plaintext number corresponding to the encrypted ciphertext is determined based on the comparison result between the check value and the signature value of the check digit in the encrypted ciphertext.

[0183] Preferably, determining the plaintext number corresponding to the encrypted ciphertext according to the comparison result of the check value and the signature value of the check bit in the encrypted ciphertext includes:

[0184] When the check value is equal to the signature value of the check digit in the encrypted ciphertext, determining that the first plaintext number is the plaintext number corresponding to the encrypted ciphertext;

[0185] When the check value is not equal to the signature value of the check bit in the encrypted ciphertext, it is determined that the encrypted ciphertext is a forged ciphertext and the encrypted ciphertext is discarded.

[0186] In step 206, a decrypted webpage URL is generated according to the plaintext number corresponding to the encrypted ciphertext.

[0187] Preferably, generating a decrypted webpage URL according to the plaintext number corresponding to the encrypted ciphertext includes:

[0188] Replacing the encrypted ciphertext in the encrypted webpage URL with a plaintext number corresponding to the encrypted ciphertext;

[0189] The web page URL including the plain text number corresponding to the encrypted ciphertext is used as the decrypted web page URL.

[0190] In one embodiment, the encrypted webpage URL: http: / / XXX.test.com / id=v41vmz4a93637cb354befb1belfdvfe7 generated by the webpage URL encryption method of this embodiment is extracted to obtain the encrypted ciphertext v41vmz4a93637cb354befb1belfdvfe7. Since the gene information bit has been specified in the ciphertext format, according to the values ​​1, I and e of the gene factor in the gene information bit, the corresponding relationship between the gene factor in the gene information bit specified by the gene reverse reduction function and the ciphertext bit to be discarded length can be known that the ciphertext bit to be discarded length of the encrypted ciphertext is the same as the to-be-filled length in the gene extraction function, which is 12 bits, and the result of the ciphertext bit of the encrypted ciphertext after discarding the interference value is v41vmz4a93. Since there is a symmetric relationship between the reverse mapping function and the mapping function f(x), the reverse mapping function f'(x) is a function that maps a string with a fixed length to any natural number from 0 to 9. Therefore, it can be known from the reverse mapping function that the numbers corresponding to v41vmz4a93 are 1, 2, and 3 respectively. According to their arrangement order, the first plaintext number 123 can be obtained. In order to prevent tampering with the encrypted ciphertext, it is necessary to verify the result through the signature value of the check bit in the encrypted ciphertext. The specific method is to substitute the obtained first plaintext number into the signature function to generate the check value of the check bit. When the check value is the same as the signature value of the check bit in the obtained encrypted ciphertext, it means that the encrypted ciphertext has not been tampered with. At this time, the encrypted webpage URL can be obtained after decryption: http: / / XXX.test.com / id=123.
