These drawings and the written description are not intended to restrict the scope of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0031] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0032] With the rapid progress of information technology, many transactions can now be efficiently completed through the network, which makes data security issues increasingly the focus of public attention and an important direction of research.

[0033] In the current technical background, in order to strengthen data security, the industry generally uses methods such as implementing white lists, black lists and other mechanisms to resist potential external security threats and attacks. However, this approach still has the possibility of data leakage.

[0034] To solve the above technical problems, the inventors propose the following technical concept: receiving request information sent by a user terminal, obtaining an IP address in the request information, obtaining question bank data according to the request information, determining an encryption public key corresponding to the IP address, encrypting the question bank data using the encryption public key, obtaining encrypted question bank data, sending the encrypted question bank data to the user terminal, and decrypting the encrypted question bank data by the user terminal to obtain the question bank data.

[0035] The present application is applied to the scenario of processing question bank data. It should be noted that the user information (including but not limited to user equipment information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards, and provide corresponding operation portal for user to choose authorization or refusal. In the embodiments of the present application, some industry existing solutions such as software, components, models, etc. may be mentioned, which should be considered as exemplary, and the purpose is only to illustrate the feasibility of the implementation of the technical solutions of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0036] Figure 1 The application scenario of the question bank data processing method provided by the embodiment of the present application is shown in the figure. As shown in the figure, Figure 1 In this scenario, it includes a user terminal 101 and a server 102.

[0037] In the specific implementation process, the user terminal 101 can include a computer, a server, a tablet, a mobile phone, a personal digital assistant (PDA), a notebook computer, etc., which can input data.

[0038] The server 102 can be implemented by using a server or a cluster composed of multiple servers with stronger processing capability and higher security, and in possible cases, a computer or a notebook computer with stronger computing capability can also be used for replacement. For example, a front-end server, a reverse proxy server, and a back-end server are composed.

[0039] The connection between the server 102 and the user terminal 101 can be wired connection or wireless connection.

[0040] The server 102 is configured to receive the request information sent by the user terminal 101, determine the encryption public key according to the IP address of the request information, encrypt the question bank data corresponding to the request information by using the encryption public key, obtain encrypted question bank data, and send the encrypted question bank data to the user terminal 101.

[0041] The user terminal 101 is configured to decrypt the received encrypted question bank data to obtain the question bank data.

[0042] It can be understood that the structure shown in the embodiment of the present application does not constitute a specific limitation on the question bank processing method. In other possible embodiments of the present application, the above-mentioned architecture can include more or fewer components than the figure, or combine certain components, or split certain components, or different component arrangement, which can be determined according to the actual application scene, and is not limited here. Figure 1 The components shown can be realized by hardware, software, or a combination of software and hardware.

[0043] The technical solutions of the present application and how the technical solutions of the present application solve the above-mentioned technical problems will be described in detail in the following specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0044] Figure 2 The flowchart of the question bank data processing method provided by the embodiment of the present application is shown in Figure 1 The execution subject of the embodiment of the present application can beFigure 1 The server in this example can be a computer or / or mobile phone, etc., and this embodiment does not impose any particular limitations on it. Figure 2 As shown, the method includes:

[0045] S201: Receive request information sent by the user terminal and obtain the Internet Protocol (IP) address from the request information.

[0046] In this step, request information can be received by receiving data packets or messages. The IP address in the request information can be obtained by reading the IP address field in the request information, or it can be read using a preset address acquisition program.

[0047] In one possible implementation, the server includes a front-end server, a server-side reverse proxy server, and a back-end server. The front-end server receives the request information and transmits it to the server-side reverse proxy server. The server-side reverse proxy server obtains the IP address of the request information, writes the IP address into the header of the request information, and sends the written request information to the back-end server. The back-end server reads the header of the request information to obtain the IP address.

[0048] S202: Obtain the question bank data based on the requested information.

[0049] This step may include searching for question bank data based on the request content of the request information; or it may include reading question bank data corresponding to the question type and number of questions in the question bank data based on the question type and number of questions in the request information.

[0050] S203: Determine the encryption public key based on the IP address.

[0051] This step may include inputting the IP address into a public key generation program to obtain an encrypted public key.

[0052] The public key generation program can be pre-written by staff. This program can perform calculations on the IP address using preset rules to obtain an encrypted public key; alternatively, it can also include obtaining a timestamp, performing calculations on the timestamp and IP address using preset rules to obtain the encrypted public key.

[0053] S204: Generate random numbers.

[0054] This step may include generating random numbers using preset programs, scripts, functions, or commands.

[0055] S205: Encrypt the question bank data using a public key and a random number to obtain the encrypted question bank data.

[0056] In this step, the encrypted public key and the random number can be combined to obtain a combined secret key.

[0057] S206: Combine the encrypted public key and the random number to obtain a combined secret key.

[0058] In this step, the encrypted public key and the random number can be combined according to a rule preset by a staff member to obtain a combined secret key.

[0059] For example, the random number can be inserted into the encrypted public key, or the data of each bit of the random number can be reversed in order and then inserted into the encrypted public key.

[0060] S207: Send the encrypted question bank data to the user terminal, so that the user terminal determines a decryption private key and decrypts the encrypted question bank using the decryption private key to obtain the question bank data.

[0061] In this step, the encrypted question bank data can be sent to the user terminal in the format of a data packet or a message.

[0062] If a timestamp is used in the calculation of the encrypted public key, the timestamp of the encrypted public key is sent together with the encrypted question bank data, so that the user terminal generates a decryption private key using a private key generation program.

[0063] As can be seen from the description of the above embodiments, the embodiments of the present application determine an encrypted public key by using the IP address of the user terminal, encrypt the obtained question bank data using the encrypted public key and a random number, combine the encrypted public key and the random number to obtain a combined secret key, and send the encrypted question bank data and the combined secret key to the user terminal, thereby achieving the effect of protecting the security of the question bank data and the secret key during transmission through multiple encryption.

[0064] In a possible implementation, in the step S203, the encrypted public key is determined according to the IP address, including:

[0065] S2031: According to the IP address, find a preset IP address and public key correspondence to obtain an encrypted public key.

[0066] In this step, the preset IP address and public key correspondence can be preset by a staff member and stored in the form of a table or a key-value pair.

[0067] As can be seen from the description of the above embodiments, the embodiments of the present application directly find the encrypted public key corresponding to the IP address according to the correspondence, which facilitates subsequent encryption of the question bank data using the public key agreed upon in advance with the terminal device and reduces the amount of calculation.

[0068] In a possible implementation, in the step S203, the encrypted public key is determined according to the IP address, including:

[0069] S2031: According to the IP address, the preset address and request number correspondence relationship is searched to obtain a target request number.

[0070] In this step, the address and request number correspondence relationship can be set according to the terminal device interaction corresponding to the IP address, and is stored in a table or key-value pair format.

[0071] S2032: Two target prime numbers are determined according to the target request number.

[0072] In this step, the request number and prime number correspondence relationship can be searched to obtain two target prime numbers.

[0073] The request number and prime number correspondence relationship can be set by a staff in advance and stored in a table or key-value pair format.

[0074] S2033: The target prime numbers are input into the Euler function to obtain a target Euler function value.

[0075] In this step, the Euler function is as follows:

[0076] φ = (p-1)(q-1)

[0077] In the formula, φ represents the target Euler function value, and p and q represent the target prime numbers. The target Euler function value can be obtained by inputting the two prime numbers into the Euler function p and q.

[0078] S2034: The product of the target prime numbers is calculated to obtain a prime number product.

[0079] In this step, the two target prime numbers are multiplied to obtain the prime number product.

[0080] For example, the two target prime numbers are 307 and 311, and the prime number product obtained by multiplying 307 and 311 is 95477. For another example, the target prime numbers are 883 and 887, and the prime number product obtained by multiplying 883 and 887 is 783221.

[0081] S2035: The public key index is determined according to the target Euler function value.

[0082] In this step, the target Euler function value can be divided by a preset value and rounded to obtain the public key index.

[0083] The preset value is greater than 0 and less than 1.

[0084] S2036: Combine the public key index and the prime product to obtain an encryption public key.

[0085] In this step, for example, the public key index is 31826, and the prime product is 95477, and the encryption public key is (95477, 31826); for another example, the public key index is 261074, and the prime product is 783221, and the encryption public key is (783221, 261074).

[0086] From the description of the above embodiments, it can be known that the embodiments of the application realize that the terminal device can obtain the public key without pre-allocating the public key by combining the request times to generate the encryption public key, reduce the possibility of leakage in the process of public key transmission, so that only the terminal device and the server can encrypt and decrypt the question bank data.

[0087] In a possible implementation, in the step S2032, two prime numbers are determined according to the target request number, including:

[0088] S321: Multiply the target request number by a preset value to obtain a target base.

[0089] In this step, the preset value can be set by the staff in advance.

[0090] For example, the target request number is 320, and the preset value is 100, and the target base is 32000; for another example, the target request number is 270, and the preset value is 200, and the target base is 54000.

[0091] S322A: Determine two unequal prime numbers greater than the target base and the smallest as target prime numbers.

[0092] In this step, for example, the target base is 35000, and the two unequal prime numbers greater than 35000 and the smallest are 35023 and 35027; for another example, the target base is 42000, and the two unequal prime numbers greater than 42000 and the smallest are 42013 and 42017.

[0093] S322B: Determine two unequal prime numbers less than the target base and the largest as target prime numbers.

[0094] In this step, for example, the target base is 38000, and the target prime numbers are 37933 and 37997; for another example, the target base is 423500, and the target prime numbers are 423481 and 423497.

[0095] In the steps S322A and S322B, the way of determining the target prime number can include searching a preset prime table, or inputting the target base into a prime calculation program written by the staff in advance.

[0096] From the description of the above embodiments, it can be known that the embodiments of the present application multiply the target request number by the preset value to obtain the target base, and find two prime numbers meeting the preset rule based on the target base, so that the same two prime numbers are found in the case that the server and the terminal device do not inform each other.

[0097] In a possible implementation, in the step S2035, the public key index is determined according to the target Euler function value, including:

[0098] S2036: determining the largest prime number less than the target Euler function value as the public key index.

[0099] This step is similar to the step S322B described above, and will not be described here.

[0100] From the description of the above embodiments, it can be known that the embodiments of the present application determine the largest prime number less than the target Euler function value as the public key index, so that the same public key index can be obtained on both sides without the interaction between the server and the terminal device, and the possibility of information leakage is reduced.

[0101] In a possible implementation, in the step S206, the encryption public key and the random number are combined to obtain the combined secret key, including:

[0102] S2061: inserting each number in the random number into the encryption public key in the order of front and back and with random intervals to obtain the combined secret key.

[0103] In this step, for example, if the random number is "12345678" and the encryption public key is inserted, the order of "12345678" is maintained. However, the values of 1, 2, 3 or more encryption public keys can be inserted as intervals, for example, if the random number is "8271" and the encryption public key is "7766991100", the combined secret key "78726697911010" can be obtained after insertion. The above random number in the combined secret key is marked with a single quotation mark "7 '8' 7 '2' 669 '7' 9110 '1' 0". It can be seen that the "8" and "2" of the random number are separated by one "7", the "2" and "7" of the random number are separated by three "669", and the "7" and "1" of the random number are separated by four "9110", but the order of the digits of the random number is maintained. For example, if the random number is "8956" and the encryption public key is "72341268", the combined secret key "872394152668" can be obtained after insertion. The above random number in the combined secret key is marked with a single quotation mark " '8' 723 '9' 41 '5' 2 '6' 68". It can be seen that the "8" and "9" of the random number are separated by three "723", the "9" and "5" of the random number are separated by two "41", and the "5" and "6" of the random number are separated by one "2", but the order of the digits of the random number is maintained.

[0104] As can be seen from the description of the above embodiments, the embodiments of the present application insert each digit of the random number into the encryption public key with random intervals to obtain a combined secret key, thereby achieving encryption of the encryption public key and the random number during transmission and reducing the possibility of data leakage.

[0105] In a possible implementation, the request information includes a question type.

[0106] Correspondingly, in S202, the question bank data is obtained according to the request information, including:

[0107] S2021: Determine whether the IP address is an IP address in the white list. If yes, obtain the corresponding question bank data according to the question type.

[0108] In this step, the IP address of the request information can be searched in the white list. If it can be found, the corresponding question bank data is obtained according to the question type. If it cannot be found, no processing is performed. Obtaining the corresponding question bank data according to the question type can include searching for the data corresponding to the question type in the question bank.

[0109] As can be seen from the description of the above embodiments, the embodiments of the present application set up a white list to screen the IP address of the request information, avoid access from external IP, and reduce data security threats.

[0110] Figure 3A flowchart illustrating the question bank data processing method provided in the embodiments of this application. Figure 2 The question bank data processing method provided in this application is applied to a user terminal. For example... Figure 3 As shown, the question bank data processing methods include:

[0111] S301: Send a request to the server so that the server can obtain the Internet Protocol IP address in the request information, obtain the question bank data according to the request information, determine the encryption public key according to the IP address, generate a random number, encrypt the question bank data using the encryption public key and the random number to obtain the encrypted question bank data, and combine the encryption public key and the random number to obtain the combined key.

[0112] In this step, the request information can be sent by sending data packets or messages.

[0113] S302: In response to receiving the encrypted question bank data and combined key sent by the server, determine the decryption private key.

[0114] This step can include directly reading the decryption private key after receiving the question bank data and the combined key, or generating the decryption private key based on its own IP address or the number of interactions with the server.

[0115] S303: Use the decryption private key and the combination key to decrypt the encrypted question bank data to obtain the question bank data.

[0116] This step may include restoring the combined key to obtain the random number in step S301 above, and using the decryption private key and the random number to decrypt the encrypted question bank data twice to obtain the question bank data.

[0117] As can be seen from the description of the above embodiments, the embodiments of this application send a request message to the server to receive encrypted question bank data sent by the server, and use the decryption private key to decrypt the encrypted question bank data to obtain the question bank data, thereby realizing encrypted transmission of question bank data and reducing the possibility of question bank data leakage.

[0118] In one possible implementation, step S302 above, determining the decryption private key, includes:

[0119] S3021: Get the target number of requests.

[0120] This step may include reading the pre-stored number of times request information is sent to the server, as the target number of requests.

[0121] The number of times a request message is sent can be recorded after each request message is sent.

[0122] S3022: Determine two target prime numbers based on the number of target requests.

[0123] S3023: input the target prime number into the Euler function to obtain a target Euler function value.

[0124] S3024: calculate the product of the target prime number to obtain a prime product.

[0125] S3025: determine a public key exponent according to the target Euler function value.

[0126] The steps S3022 to S2035 are similar to the steps S2032 to S2035, and will not be described here again.

[0127] S3026: input the public key exponent and the target Euler function value into a preset equation to obtain a to-be-solved equation.

[0128] In this step, the preset equation is as follows:

[0129] ax + by = 1

[0130] In the formula, a represents the public key exponent, b represents the target Euler function, x and y are variables, and the positive solution of the variables obtained by solving is taken as a private key exponent.

[0131] S3027: solve the to-be-solved equation to obtain the private key exponent.

[0132] In this step, the extended Euclidean algorithm can be used to solve the to-be-solved equation to obtain the private key exponent.

[0133] S3028: combine the private key exponent and the prime product to obtain a decryption private key.

[0134] This step is similar to the step S2036 described above, and will not be described here again. In a possible implementation, the encryption public key in the step S2036 described above and the decryption private key in this step are stored in ASN.1 format or other formats.

[0135] As can be seen from the description of the above embodiments, the decryption private key can be obtained without pre-communication with the server by calculating the decryption private key according to the request times stored by the user terminal, thereby increasing the security of data transmission.

[0136] In a possible implementation, in the step S303, the encrypted question bank data is decrypted according to the decryption private key and the combination secret key to obtain the question bank data, including:

[0137] S3031: combine the public key exponent and the prime product to obtain an encryption public key.

[0138] This step is similar to the step S3036 described above, and will not be described here again.

[0139] S3032: Determine the value of the first bit of the encryption public key as the target public key value.

[0140] In this step, for example, the encryption public key is "871098", the first "8" is determined as the target public key value; for example, the encryption public key is "73981393", the first "7" is determined as the target public key value.

[0141] S3033: Determine the value of the first bit of the combined secret key as the target secret key value.

[0142] This step is similar to the above step S3032, which will not be described here.

[0143] S3034: If the target public key value and the target secret key value are the same, determine the value of the next bit of the encryption public key as the new target public key value, and determine the value of the next bit of the target secret key value as the new target secret key value.

[0144] In this step, for example, the combined secret key is "72659012", the encryption public key is "76502", after the above steps S3033 and S3034, the original target secret key value and the target public key value are both 7, then the next bit "2" of the combined secret key is determined as the new target secret key value, and the next bit "6" of the encryption public key is determined as the target public key value. For example, the combined secret key is "74947135", the encryption public key is "74473", after the above steps S3033 and S3034, the original target secret key value and the target public key value are both 7, then the next bit "4" of the combined secret key is determined as the new target secret key value, and the next bit "4" of the encryption public key is determined as the target public key value.

[0145] S3035: If the target public key value and the target secret key value are different, determine the target secret key value as the target random number value, and determine the value of the next bit of the target secret key value as the new target secret key value.

[0146] In this step, referring to the first example of the above step S3034, the second bit of the combined secret key and the second bit of the encryption public key are different, then the second bit of the combined secret key is determined as the target random number value, and the value of the third bit of the combined secret key is determined as the new target secret key value.

[0147] S3036: Repeat the step of determining that the target public key value and the target secret key value are the same until the target public key value is the value of the last bit of the encryption public key, and the obtained target random number value is spliced to obtain the above random number.

[0148] In this step, continuing to refer to the first example of step S3034 described above, after repeating the steps S3034 and S3035 described above, all the target random number values obtained are "2", "9", and "1", and the random number "291" is obtained by concatenating them. Referring to the second example of step S3034 described above, after repeating the steps S3034 and S3035 described above, all the target random number values obtained are "9", "1", and "5", and the random number "915" is obtained by concatenating them.

[0149] S3037: decrypting the encrypted question bank data by using the decryption private key and the random number, to obtain the question bank data.

[0150] In this step, the order of decrypting the encrypted question bank data can be opposite to the order of encryption in step S205 described above. If the encryption is first encrypted by using the encryption public key and then encrypted by using the random number, the decryption is first decrypted by using the random number and then decrypted by using the decryption private key. If the encryption is first encrypted by using the random number and then encrypted by using the encryption public key, the decryption is first decrypted by using the decryption private key and then decrypted by using the random number.

[0151] As can be seen from the description of the above examples, the embodiments of the present application split the random number generated by the server from the combined secret key by comparing each bit of data of the encryption public key and the combined secret key, so that the decryption of data is realized without the encryption public key, the random number, and the decryption private key being disclosed to the outside.
