[0057] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] In practical applications, encrypting data during data transmission and data storage is the simplest and most effective method. However, after the concept of encryption emerged, technicians in this field have been studying new encryption algorithms, from Morse code, which uses different combinations of long and short signals to encrypt all numerical values ​​in fixed algorithms such as the data summary MD5 encryption algorithm, to encryption algorithms such as the DES symmetric encryption algorithm that require users to add keys or offset vectors. Although the logic of the encryption algorithm is becoming more and more complex, no matter how many rounds of XOR, permutation, substitution, and shift operations are used, the order of operations is constantly changed, or the user is allowed to participate in the encryption process to the maximum extent, the one-to-one correspondence between plaintext and ciphertext will not change. After a certain amount of plaintext and ciphertext are collected, through big data analysis and comparison, it is highly likely that this one-to-one correspondence can be found, thereby increasing the risk of leakage of encrypted data.

[0059] Reference Figure 1 , shows a flow chart of the steps of a data encryption method provided in an embodiment of the present invention, which may specifically include the following steps:

[0060] Step 101, obtaining data to be encrypted, and splitting the data to be encrypted into unit data;

[0061] Step 102, using the unit data to determine the number of data bits of the data to be encrypted;

[0062] Step 103, using the number of data bits to divide the circle, generating a plurality of sectors; the sectors have corresponding angle interval values; the number of sectors is equal to the number of data bits;

[0063] Step 104, randomly assigning the unit data to the sectors, so that a plurality of the unit data correspond to a plurality of the angle interval values ​​one by one;

[0064] Step 105, obtaining time information, and using the time information to determine a first encryption value for the unit data in the angle interval value based on a first time algorithm;

[0065] Step 106: Generate first encrypted data for the data to be encrypted using the first encryption value.

[0066] In a specific implementation, the data to be encrypted in the implementation rules of the present invention can be any characters, for example, English letters, Latin letters, Chinese pinyin, Chinese phonetic symbols, Chinese characters, etc., or numbers or other symbols. In order to enable those skilled in the art to better understand the embodiments of the present invention, lowercase English letters and numbers will be used as examples to illustrate the encryption process for the data to be encrypted. Of course, those skilled in the art can encrypt other types of data in the following manner, and the embodiments of the present invention are not limited to this.

[0067] After obtaining the data to be encrypted, the embodiment of the present invention can split the data to be encrypted into unit data in equal or unequal divisions. For example, 26 lowercase English letters "AZ" and Arabic numerals "0-9" can be used as the data to be encrypted, that is, the data to be encrypted can be a string of "abcdefghijklmnopqrstuvwxyz0123456789". After obtaining the data to be encrypted, it can be split into three unit data of "abcdefgh", "ijklmnopqrstuvwxyz", and "0123456789", or it can be split into 13 unit data of "ab", "cd", "ef", "gh", "ij", "kl", "mn", "op", "qr", "st", "uv", "wx", "yz", "01", "23", "45", "67", and "89".

[0068] Optionally, the unit data in the embodiment of the present invention may be minimum unit data, for example, each letter and number in the string of characters "abcdefghijklmnopqrstuvwxyz0123456789" is regarded as a unit data.

[0069] After completing the splitting of the data to be encrypted, the embodiment of the present invention can use unit data to determine the number of data bits of the data to be encrypted. For example, the data to be encrypted "abcdefghijklmnopqrstuvwxyz0123456789" is divided into three unit data of "abcdefgh", "ijklmnopqrstuvwxyz", and "0123456789", and the number of data bits of the data to be encrypted is 3 bits; the data to be encrypted "abcdefghijklmnopqrstuvwxyz0123456789" is divided into "ab", "cd", "ef", "gh", "ij", "kl", "mn", "op", "qr", "st", "uv", "wx", "yz", "01", "23", "45", "67", and "89", and the number of data bits of the data to be encrypted is 13 bits.

[0070] In a specific implementation, the embodiment of the present invention may use the number of data bits to divide the circle to generate multiple sectors, and the sectors have internal angles, so the sectors may have corresponding angle interval values, and the number of sectors may be equal to the number of data bits.

[0071] Optionally, in the embodiment of the present invention, the original image may be divided into equal parts or unequal parts.

[0072] After the sector is generated, the embodiment of the present invention can randomly distribute the unit data to the sector so that the multiple unit data correspond to the multiple angle interval values ​​one by one.

[0073] refer to Figure 2 , Figure 2 1 is a schematic diagram of the relationship between sectors and unit data provided by an embodiment of the present invention. If the data to be encrypted, "abcdefghijklmnopqrstuvwxyz0123456789", is divided into four unit data, namely, unit data 201 "abcdefgh", unit data 202 "0123456789", unit data 203 "stuvwxyz", and unit data 204 "ijklmnopqr", the number of bits of the data to be encrypted is 4 bits, and a circle can be divided into four sectors, namely, sector 205, sector 206, sector 207, and sector 208. The angle interval value of sector 205 can be 0° to 30°. The angle interval value of sector 206 can be 30° to 180°, the angle interval value of sector 207 can be 180° to 210°, and the angle interval value of sector 208 can be 210° to 360°. Among them, the angle interval value corresponding to unit data 201 "abcdefgh" can be 0° to 30°, the angle interval value corresponding to unit data 202 "0123456789" can be 30° to 180°, the angle interval value corresponding to unit data 203 "stuvwxyz" can be 180° to 210°, and the angle interval value corresponding to unit data 204 "ijklmnopqr" can be 210° to 360°.

[0074] After completing the allocation of the unit data, the embodiment of the present invention can obtain time information, and can use the time information to determine a first encryption value for the unit data in the angle interval value based on the first time algorithm.

[0075] For example, the data to be encrypted "abcdefghijklmnopqrstuvwxyz0123456789" is split into the smallest unit data, that is, the number of bits of the data to be encrypted is 36, the circle is divided into 36 sectors, and the unit data is randomly assigned to the sectors, so that multiple unit data correspond to multiple angle interval values ​​one by one, and the following correspondence table can be obtained:

[0076] Center Angle Corresponding content Center Angle Corresponding content 0～10 7 181～190 f 11～20 q 191～200 4 21～30 w 201～210 g 31～40 e 211～220 h 41～50 5 221～230 j 51～60 r 231～240 k 61～70 t 241～250 0 71～80 y 251～260 9 81～90 8 261～270 l 91～100 u 271～280 z 101～110 i 281～290 x 111～120 o 291～300 2 121～130 6 301～310 c 131～140 p 311～320 v 141～150 a 321～330 b 151～160 1 331～340 3 161～170 s 341～350 n 171～180 d 351～360 m

[0077] Among them, each unit data corresponds to an angle interval value.

[0078] For example, assuming that the time information of the day to be encrypted for the encrypted data is March 30, 2022, this time information can be obtained and recorded as 20220330. The date digit of the time information can be divided by 3 and the remainder is used to determine the number of decimal places to be retained. If the remainder is 0, an integer is taken; if the remainder is 1, 1 decimal place is taken; if the remainder is 2, 2 decimal places are taken; 30÷3=10, if the remainder is 0, an integer is taken, then the first encrypted value of the unit data "e" can be a random integer between 31-40, such as 36 or 39, which can be recorded as "036" and "039" respectively, that is, any integer between 31-40 can represent the unit data "e", and the first encrypted value of the unit data "5" can be 50 or 47 can be recorded as "050" or "047" respectively, that is, any integer between 41 and 50 can represent the unit data "5". Similarly, if the date on which the encrypted data is encrypted is April 1, 2022, this date can be obtained, and the time information is recorded as 20220401. The last two digits of 0220401 are divided by three and the remainder is used to determine the number of decimal places. Then, the first encrypted value of the unit data "5" can be any number with two decimal places between 41 and 50, such as 42 degrees 9 minutes or 44 degrees 7 minutes, which can be recorded as "4209" or "4407" respectively. That is, any number with two decimal places between 41 and 50 can represent the unit data "5".

[0079] In the embodiment of the present invention, after determining the first encryption values ​​corresponding to all the unit data, a plurality of first encryption values ​​may be combined to generate first encrypted data for the data to be encrypted.

[0080] Optionally, the first encrypted value above 360 ​​degrees may correspond to unit data expressing a space to separate words and numbers.

[0081] According to an embodiment of the present invention, data to be encrypted is obtained, and the data to be encrypted is split into unit data; the unit data is used to determine the number of data bits of the data to be encrypted; the number of data bits is used to divide a circle to generate multiple sectors; the sectors have corresponding angle interval values; the number of sectors is equal to the number of data bits; the unit data is randomly distributed to the sectors so that multiple unit data correspond to multiple angle interval values ​​one by one; time information is obtained, and the time information is used to determine a first encryption value for the unit data in the angle interval value based on a first time algorithm; first encrypted data for the data to be encrypted is generated through the first encryption value, thereby avoiding the simplification of encryption results between plaintext and ciphertext, and also avoiding the simplification of the correspondence between plaintext and ciphertext, thereby improving the security of confidential data.

[0082] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0083] In an optional embodiment of the present invention, it also includes:

[0084] Generate a first binary number sequence using the first encrypted value;

[0085] Reversing the first binary number sequence bit by bit to generate a second binary number sequence;

[0086] Generate a second encrypted value using the second binary number sequence;

[0087] Second encrypted data is generated using the second encrypted value.

[0088] In a specific implementation, the embodiment of the present invention may use the first encrypted value to generate a first binary number sequence, and perform bit-by-bit inversion on the first binary number sequence to generate a second binary number sequence, and then use the second binary number sequence to generate a second encrypted value.

[0089] For example, the first encryption value of the letter c is 304. 304 is converted into binary to generate the first binary sequence "100110000", and then "100110000" is reversed bit by bit to generate the second binary sequence "011001111". After the second binary sequence is generated, the second binary sequence "011001111" can be converted into decimal to generate the second encryption value 207.

[0090] After all the first encrypted data are converted into the second encrypted values, the embodiment of the present invention can generate the second encrypted data through the second encrypted values.

[0091] The embodiment of the present invention generates a first binary number sequence by using the first encryption value; generates a second binary number sequence by bit-by-bit inversion of the first binary number sequence; generates a second encryption value by using the second binary number sequence; and generates second encrypted data by using the second encryption value, thereby further improving the security of confidential data.

[0092] In an optional embodiment of the present invention, it also includes:

[0093] Using the second encrypted value, calculate an arc length corresponding to the second encrypted value;

[0094] Using the arc length and the time information, a third encrypted value is calculated based on a second time algorithm;

[0095] The third encrypted data is generated by the third encrypted value.

[0096] In a specific implementation, the second encrypted value of the embodiment of the present invention can still represent the inner angle of the sector, so the second encrypted value can be used to calculate the arc length corresponding to the second encrypted value.

[0097] For example, the arc length L can be calculated by the following formula: (r / 180)*π*n, where L is the arc length, r is the radius, which can be 1; π is the pi, which can be 3; and n is the center angle, which can be the second encrypted value.

[0098] After calculating the arc length corresponding to the second encrypted value, the arc length and time information may be used to calculate a third encrypted value based on the second time algorithm.

[0099] For example, assuming that the time information of the day on which the encrypted data is encrypted is March 30, 2022, this time information can be obtained and recorded as 20220330. The date digit of the time information can be divided by 2 and the remainder can be used to determine the number of decimal places to be retained. Suppose the remainder is 0, and 2 decimal places are taken; the remainder is 1, and 3 decimal places are taken; 30÷2=15, the remainder is 0, and 2 decimal places are taken. The second encryption value is 207, and the arc length of the sector with a central angle of 207° is 3.45, recorded as 345, and the third encryption value is 345.

[0100] After all the second encrypted data are converted into the third encrypted value, the embodiment of the present invention can generate the third encrypted data through the third encrypted value.

[0101] In an embodiment of the present invention, the arc length corresponding to the second encryption value is calculated by using the second encryption value; the third encryption value is calculated based on a second time algorithm using the arc length and the time information; and third encrypted data is generated by the third encryption value, thereby further improving the security of confidential data.

[0102] In an optional embodiment of the present invention, it also includes:

[0103] Generate a fourth encrypted value by performing an XOR operation on the time information and the third encrypted value;

[0104] Fourth encrypted data is generated using the fourth encrypted value.

[0105] In a specific implementation, the embodiment of the present invention can generate the fourth encrypted value by performing an XOR operation on the time information and the third encrypted value.

[0106] For example, 345 is converted into a binary number sequence 101011001. Assuming that the time information of the encrypted data is March 30, 2022, the time information can be obtained and recorded as 20220330. 20220330 is converted into a binary number sequence 1001101001000100110101010. By performing an XOR operation on the time information and the third encrypted value, 345 (binary 101011001) is obtained. 20220330 (binary 1001101001000100110101010)=20220147 (binary 1001101001000100011110011), that is, the fourth encrypted value is 20220147 (binary 1001101001000100011110011).

[0107] After all the third encrypted data are converted into fourth encrypted values, the embodiment of the present invention can generate fourth encrypted data through the fourth encrypted values.

[0108] The embodiment of the present invention generates a fourth encrypted value by performing an XOR operation on the time information and the third encrypted value; and generates fourth encrypted data by using the fourth encrypted value, thereby further improving the security of confidential data.

[0109] In an optional embodiment of the present invention, the time information is a key.

[0110] In practical applications, using time information as a key can ensure the timeliness of the key, thereby further improving the security of confidential data. At the same time, the key of the embodiment of the present invention can also be used for decryption to restore the ciphertext to plaintext, that is, to restore the encrypted data.

[0111] For example, assuming that the time information of the day on which the encrypted data is encrypted is March 30, 2022, this time information can be obtained, and the key is 20220330. The fourth encrypted value in the fourth encrypted data is 20220147. By performing bitwise XOR calculation on the fourth encrypted value 20220147 and the key 20220330, the third encrypted value can be calculated to be 345. The remainder of the date digit 30 divided by 2 is 0, so the third encrypted value 345 can be obtained. The arc length should be 3.45. Using the arc length formula L = (r / 180)*π*n (L is the arc length, r is 1, π is 3, and n is the degree of the center angle), the second encrypted value is calculated to be 207. The second encrypted value 207 is bitwise inverted to calculate the first encrypted value to be 304. The remainder of the date digit 30 divided by 2 is 0, so 304 corresponds to 304 degrees. 304 degrees is in the range of 301 to 310 degrees. In the fourth encrypted data, the result corresponding to the fourth encrypted value is c.

[0112] In an optional embodiment of the present invention, the unit data includes actual unit data used to actually express the data to be encrypted, and virtual unit data not used to actually express the data to be encrypted.

[0113] In practical applications, embodiments of the present invention may split the data to be encrypted into unit data in a multi-partition manner. Specifically, the data to be encrypted may be split into actual unit data that actually expresses the data to be encrypted and virtual unit data that is not used to actually express the data to be encrypted.

[0114] For example, when the data to be encrypted is a string of characters "0123456789", the data to be encrypted can be changed to a sequence of "0_1_2_3_4_5_6_7_8_9", where "1", "2", "3", "4", "5", "6", "7", "8", and "9" actually express the actual unit data of the data to be encrypted, and the other 9 "_" can be virtual unit data that is not used to actually express the data to be encrypted. If the sequence of "0_1_2_3_4_5_6_7_8_9" is split into the smallest unit data, the number of bits of the data to be encrypted is 19, which means that the circle can be It is divided into 19 sectors. After the unit data are randomly assigned to the sectors, the inner angles of 9 sectors will correspond to "_". However, in actual applications, if virtual unit data appears, that is, "_" appears during the decoding process, it can be regarded as a third party trying to crack the encryption algorithm, or the encrypted data is attacked by junk data. Therefore, the embodiment of the present invention can form unit data by adopting actual unit data for actually expressing the data to be encrypted and virtual unit data that is not used to actually express the data to be encrypted. When virtual unit data appears during decoding, a security warning is issued, thereby further improving the security of confidential data.

[0115] Furthermore, the embodiment of the present invention encrypts data by utilizing the center angle of a circle, thereby converting the encryption relationship into one-to-many, thereby achieving the same original data, being encrypted at the same time, and having multiple ciphertext results; the complexity of the algorithm is increased by combining the sector arc length formula, bitwise inversion, and bitwise XOR; the number of decimal places to be retained is determined by time information, so that the possibility of the encryption result of the same original text within a unit time is different from that at the previous time; and the timeliness is guaranteed by utilizing the date as the key.

[0116] In order to enable those skilled in the art to better understand the embodiments of the present invention, a complete example is used below to illustrate the embodiments of the present invention.

[0117] Step 1: Divide the circle into equal parts as needed. For example, if you need to encrypt 26 lowercase English letters and Arabic numerals 0-9, divide the circle into 36 equal parts.

[0118] Step 2: Randomly assign the minimum atomic data source to the split sectors to obtain the following table.

[0119]

[0120]

[0121] Step 3: The center angle of the sector is the encrypted value range of English letters or Arabic numerals. The number of decimal places to be retained is determined by dividing the last two digits of the date by three using data transmission (storage) and taking the remainder (if the remainder is 0, take an integer; if the remainder is 1, take 1 decimal place; if the remainder is 2, take 2 decimal places). For example, when data is stored on March 30, 2022 (20220330), 30 divided by 3 has a remainder of 0, and the integer is taken. 36 degrees (036) corresponds to the English letter e, 39 degrees (039) also corresponds to the English letter e, and 50 degrees (050) corresponds to the Arabic numeral 5; when data is stored on April 1, 2022 (20220401), 01 is divided by 3, and the remainder is 1. One decimal place is retained, 36 degrees 3 minutes (0363) corresponds to the English letter e, 39 degrees 0 minutes (0390) also corresponds to the English letter e, and 50 degrees 9 minutes (0509) corresponds to the Arabic numeral 5. Spaces above 360 ​​degrees are used to split words and numbers.

[0122] Step 4: Replace the English words or Arabic numerals with the corresponding center angles according to the corresponding relationship, and then perform bitwise inversion. For example, the English letter c corresponds to 304 (binary 100110000), and the bitwise inversion result is 207 (binary 011001111).

[0123] Step 5: Take the arc length of the sector corresponding to the central angle of the circle within the unit circle (keep two decimal places) L = (r / 180) * π * n (L is the arc length, r is 1, π is 3, and n is the degree of the central angle of the circle). Use data transmission (storage) to divide the date and month of the day by two and take the remainder to determine the number of decimal places to be retained (remainder is 0, take 2 decimal places; remainder is 1, take 3 decimal places). For example, March 30, 2022 (20220330) is used to store data, 30 divided by 2, the remainder is 0, take 2 decimal places, and the arc length of the sector corresponding to the central angle of 207 degrees is 3.45, which is recorded as 345. Furthermore, the encryption and decryption parties can agree on the decimal places to be retained for π in the formula for the arc length of the sector, or they can agree on the order of bitwise inversion and bitwise XOR in the entire algorithm.

[0124] Step 6: Use the date of transmission (storage) as the key. During transmission, the "timestamp" parameter is added to distinguish the key. When storing, the "save time" is used to distinguish the key. For example, March 30, 2022 is recorded as 20220330. The central angle of the circle corresponds to the arc length of the sector. Perform bitwise XOR, such as 345 (binary 101011001) xor 20220330 (binary 1001101001000100110101010) = 20220147 (binary 1001101001000100011110011).

[0125] Step 7: Decryption

[0126] Decryption is the reverse processing of the encryption result.

[0127] For example, on March 30, 2022, the encryption result of c (the central angle is 304) is 20220147. The decryption process is as follows: (the sixth step is reverse processing) 20220147 is bitwise XORed, the key is 20220330, and the result is 345; (the fifth step is reverse processing) 30 is divided by 2, and the remainder is 0, so the arc length corresponding to 345 is 3.45. Using the arc length formula L = (r / 180)*π*n (L is the arc length, r is 1, π is 3 , n is the degree of the center angle), calculate the center angle, the result is 207; (the fourth step is reverse processing) 207 is bitwise inverted, the result is 304; (the third step is reverse processing) 30 is divided by 3, the remainder is 0, and 304 corresponds to 304 degrees. 304 degrees is in the range of 301 degrees to 310 degrees, and the corresponding result is c, that is, encryption: c→304→207→345→20220147; decryption: 20220147→345→207→304→c.

In the embodiments of the present invention, the electronic device includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted terminal, a wearable device, and a pedometer.

[0155] It should be understood that in the embodiment of the present invention, the radio frequency unit 401 can be used for receiving and sending signals during information transmission or communication. Specifically, after receiving downlink data from the base station, it is sent to the processor 410 for processing; in addition, uplink data is sent to the base station. Generally, the radio frequency unit 401 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 401 can also communicate with the network and other devices through a wireless communication system.

[0157] The audio output unit 403 can convert the audio data received by the RF unit 401 or the network module 402 or stored in the memory 409 into an audio signal and output it as sound. Moreover, the audio output unit 403 can also provide audio output related to a specific function performed by the electronic device 400 (for example, a call signal reception sound, a message reception sound, etc.). The audio output unit 403 includes a speaker, a buzzer, a receiver, etc.

[0158] The input unit 404 is used to receive audio or video signals. The input unit 404 may include a graphics processor (GPU) 4041 and a microphone 4042, and the graphics processor 4041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode.

The image frame processed by the graphics processor 4041 can be stored in the memory 409 (or other storage medium) or sent via the radio frequency unit 401 or the network module 402. The microphone 4042 can receive sound and can process such sound into audio data. The processed audio data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 401 in the case of a telephone call mode.

[0159] The electronic device 400 also includes at least one sensor 405, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor includes an ambient light sensor and a proximity sensor, wherein the ambient light sensor can adjust the brightness of the display panel 4061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 4061 and / or the backlight when the electronic device 400 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary, which can be used to identify the posture of the electronic device (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; the sensor 405 can also include a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, etc., which will not be repeated here.

Specifically, the user input unit 407 includes a touch panel 4071 and other input devices 4072. The touch panel 4071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 4071 or near the touch panel 4071 using any suitable object or accessory such as a finger, stylus, etc.). The touch panel 4071 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the contact point coordinates, and then sends it to the processor 410, receives the command sent by the processor 410 and executes it.

[0162] Furthermore, the touch panel 4071 may be overlaid on the display panel 4061. When the touch panel 4071 detects a touch operation on or near it, it is transmitted to the processor 410 to determine the type of the touch event. Then, the processor 410 provides a corresponding visual output on the display panel 4061 according to the type of the touch event. Figure 4 In the figure, the touch panel 4071 and the display panel 4061 are two independent components to realize the input and output functions of the electronic device.

It executes various functions of the electronic device and processes data by running or executing software programs and / or modules stored in the memory 409, and calling data stored in the memory 409, so as to monitor the electronic device as a whole. The processor 410 may include one or more processing units; preferably, the processor 410 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 410.

[0166] The electronic device 400 may also include a power supply 411 (such as a battery) for supplying power to each component. Preferably, the power supply 411 may be logically connected to the processor 410 through a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.
