[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In today's information age, internet technology is no longer unfamiliar. However, as user information is increasingly used online, the risk of information leakage is also increasing. If a user accidentally discloses their password during registration, it can have significant negative consequences, such as account theft leading to financial losses. Therefore, how to encrypt passwords has become a problem that those skilled in the art need to overcome. However, in practical applications, most existing password encryption methods use common methods, which are susceptible to cracking. This invention provides an encrypted data generation method, an encrypted data generation device, an electronic device, and a computer-readable storage medium. By combining byte streams and timestamps, and based on the hyperboloid formula in quadratic surfaces, the password is split and encrypted to improve the security of the data to be encrypted.

[0045] Reference Figure 1 The diagram illustrates a flowchart of an encrypted data generation method provided in an embodiment of the present invention, which may specifically include the following steps:

[0046] Step 101: Obtain the data to be encrypted, the first time information, and the second time information;

[0047] Step 102: Split the data to be encrypted according to a preset ratio to generate a first sub-data to be encrypted and a second sub-data to be encrypted;

[0048] Step 103: Generate first sub-encrypted data using the first sub-data to be encrypted and the first time information;

[0049] Step 104: Generate second sub-encrypted data using the second sub-data to be encrypted and the second time information;

[0050] Step 105: Generate third sub-encrypted data using the data to be encrypted;

[0051] Step 106: Generate encrypted data based on the formula for a single-leaf hyperboloid in a quadratic surface using the first sub-encrypted data, the second sub-encrypted data, and the third sub-encrypted data.

[0052] In a specific implementation, the data to be encrypted in this embodiment of the invention can be a user password.

[0053] In practical applications, a user password can be a string of characters. For example, the string "abc123." can be used as a user password.

[0054] In practical applications, to improve the immediacy of encryption, real-time information can be used. Therefore, in an optional embodiment of the present invention, the first time information and the second time information can be time information at the time of acquiring the data to be encrypted, and the first time information and the second time information can be different time information. For example, when acquiring the data to be encrypted, an instant timestamp for the data to be encrypted can be generated. This instant timestamp can express the time when the data to be encrypted was acquired, and then the instant timestamp can be used as time information. Specifically, the instant timestamp can be a millisecond-level timestamp containing millisecond values ​​or a timestamp containing dates, etc. That is, the first time information can be a microsecond value or a millisecond value. The first time information can be expressed in units of time such as centiseconds, minutes, seconds, minutes, hours, days, weeks, months, and years. Similarly, the second time information can also be expressed in units of time such as microseconds, milliseconds, centiseconds, minutes, seconds, minutes, hours, days, weeks, months, and years. However, the first time information is different from the second time information. For example, in a timestamp, if the first time information is the timestamp millisecond value, then the second timestamp is the day value. Of course, the above examples are only examples, and those skilled in the art can use any unit of time as the first or second time information. In this regard, the embodiments of the present invention do not limit this.

[0055] Of course, the first time information and the second time information can also be any other time information. For example, when acquiring data to be encrypted, a timestamp for the data to be encrypted can be generated. This timestamp can represent any time, and then the timestamp is used as time information. Specifically, the timestamp can be a millisecond-level timestamp containing a millisecond value or a timestamp containing a date, etc. This embodiment of the invention does not limit this.

[0056] In a specific implementation, the embodiments of the present invention can split the data to be encrypted according to a preset ratio. For example, the user password can be a string "abc123." composed of characters. Then, "abc123." can be split into two parts according to a percentage. The first part is 60% of the percentage, and the second part is 40% of the percentage. That is, the first part is "abc1" and the second part is "23." Then, the first part "abc1" can be used as the first sub-data to be encrypted, and the second part "23." can be used as the second sub-data to be encrypted.

[0057] Of course, the above examples are merely illustrative. Those skilled in the art can use any other percentage value to split the data to be encrypted, thereby generating the first sub-data to be encrypted and the second sub-data to be encrypted. In this regard, the embodiments of the present invention do not impose any limitations.

[0058] After obtaining the first time information and generating the first sub-data to be encrypted, embodiments of the present invention can use the first sub-data to be encrypted and the first time information to generate the first sub-encrypted data.

[0059] In a specific implementation, the embodiments of the present invention can extract the time value of the first time information, for example, extract the millisecond value of the instant timestamp, assuming that the millisecond value is 11658120633856, and use this as the first time information. The first sub-data to be encrypted is "abc1". Therefore, the embodiments of the present invention can concatenate the first sub-data to be encrypted and the first time information to generate the first sub-encrypted data abc11658120633856.

[0060] After obtaining the second time information and generating the second sub-data to be encrypted, embodiments of the present invention can use the second sub-data to be encrypted and the second time information to generate the second sub-encrypted data.

[0061] In a specific implementation, the embodiments of the present invention can extract the time value of the second time information, for example, extract the number of days of the instant timestamp, assuming that the number of days is 319853, and use this as the second time information. The second sub-data to be encrypted is "23." Therefore, the embodiments of the present invention can concatenate the second sub-data to be encrypted and the second time information to generate the second sub-encrypted data 23.319853.

[0062] In this embodiment of the invention, a third sub-encrypted data can be generated from the data to be encrypted. Specifically, the third sub-encrypted data can be encrypted data that is different from the first and second sub-encrypted data. For example, if the data to be encrypted is "abc123.", "abc123." can be directly used as the third sub-encrypted data, or "abc123." can be converted into other strings through any algorithm. These strings can be different from both the first and second sub-encrypted data.

[0063] After generating the first sub-encrypted data, the second sub-encrypted data, and the third sub-encrypted data, embodiments of the present invention can use the first sub-encrypted data, the second sub-encrypted data, and the third sub-encrypted data to generate encrypted data based on the formula for a single-leaf hyperboloid in a quadratic surface.

[0064] In practical implementation, the formula for a hyperboloid with one sheet in a quadratic surface is as follows:

[0065]

[0066] Where a, b, and c can be constants. In this embodiment of the invention, the first sub-encrypted data can be used as the x value, the second sub-encrypted data as the y value, and the third sub-encrypted data as the z value, and then the encrypted data H can be calculated.

[0067] In this embodiment of the invention, the security of the data to be encrypted is improved during the encryption process by acquiring the data to be encrypted, first time information, and second time information; splitting the data to be encrypted according to a preset ratio to generate first sub-data to be encrypted and second sub-data to be encrypted; generating first sub-encrypted data using the first sub-data to be encrypted and the first time information; generating second sub-encrypted data using the second sub-data to be encrypted and the second time information; generating third sub-encrypted data using the data to be encrypted; and generating encrypted data based on the formula for a hyperboloid in a quadratic surface using the first sub-encrypted data, the second sub-encrypted data, and the third sub-encrypted data.

[0068] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0069] In an optional embodiment of the present invention, the first time information is a timestamp in milliseconds, and the step of generating the first sub-encrypted data using the first sub-data to be encrypted and the first time information includes:

[0070] The first sub-data to be encrypted and the timestamp millisecond value are concatenated to generate the first sub-encrypted data.

[0071] In practical applications, the stronger the randomness of the generated encrypted data, the stronger the security of the data to be encrypted. Shorter time units tend to correspond to higher randomness in time information. For example, if two different pieces of data to be encrypted are obtained on the same day, and the timestamp is in days, then the time information corresponding to these two pieces of data to be encrypted will be the same. If the timestamp is in seconds, even if two different pieces of data to be encrypted are obtained on the same day, the time information of these two pieces of data to be encrypted will most likely not be the same.

[0072] As can be seen from the above, millisecond-level time values ​​often have high randomness. In specific implementations, the first time information in this embodiment of the invention can be a timestamp millisecond value. This embodiment of the invention can concatenate the first sub-data to be encrypted and the timestamp millisecond value to generate the first sub-encrypted data. For example, the first sub-data to be encrypted is "abc1", and the timestamp millisecond value is 11658120633856. Therefore, this embodiment of the invention can concatenate the first sub-data to be encrypted and the first time information to generate the first sub-encrypted data abc11658120633856.

[0073] This invention improves the randomness of the first sub-encrypted data and further enhances the security of the data to be encrypted by concatenating the first sub-encrypted data with the timestamp millisecond value.

[0074] In an optional embodiment of the present invention, the second time information is a timestamp in days, and the step of generating the second sub-encrypted data using the second sub-data to be encrypted and the second time information includes:

[0075] The second sub-data to be encrypted is concatenated with the timestamp day value to generate the second sub-encrypted data.

[0076] In practical applications, to enhance the randomness of encrypted data, different time information can be used to generate encrypted data. In actual production, data is usually archived and saved using days as the time unit. Therefore, in this embodiment of the invention, when acquiring data to be encrypted, a timestamp for the data to be encrypted is generated, and the number of days of the timestamp is taken as the second time information. Then, the second sub-data to be encrypted and the number of days of the timestamp are concatenated to generate the second sub-encrypted data. For example, if the number of days of the timestamp is 319853 and the second sub-data to be encrypted is "23.", then this embodiment of the invention can concatenate the second sub-data to be encrypted and the second time information to generate the second sub-encrypted data 23.319853.

[0077] In this embodiment of the invention, the security of the data to be encrypted is further improved by concatenating the second sub-data to be encrypted and the timestamp day value to generate the second sub-encrypted data.

[0078] In an optional embodiment of the present invention, the data to be encrypted is a string, and the step of generating third sub-encrypted data from the data to be encrypted includes:

[0079] The string is converted into a byte stream, and the byte stream is used as the third sub-encrypted data.

[0080] In practical applications, generating encrypted data with a fixed number of bits may pose a risk of reverse engineering. Therefore, this embodiment of the invention can convert the string into a byte stream and use the byte stream as the third sub-encrypted data. For example, the obtained data to be encrypted, “abc123.”, can be converted into the byte stream “dfdfa35afas21asadas9dskjasfas0w236faasas2355z2asdaas2df94sdasd2123123asda1szc... (the following part is omitted)”, and this byte stream can be used as the third sub-encrypted data.

[0081] For example, embodiments of the present invention can convert a string into a byte stream using the following code:

[0082]

[0083]

[0084]

[0085]

[0086]

[0087] Of course, the above examples are merely illustrative. Those skilled in the art can use other methods to convert strings into byte streams according to actual needs. In this regard, the embodiments of the present invention do not impose any limitations.

[0088] In this embodiment of the invention, by converting the string into a byte stream and using the byte stream as the third sub-encrypted data, the third sub-encrypted data becomes an infinite-length non-cyclic character stream, thus preventing the encrypted data from being reverse-engineered and further improving the security of the data to be encrypted.

[0089] To enable those skilled in the art to better understand the embodiments of the present invention, a complete example is provided below to illustrate the embodiments of the present invention.

[0090] refer to Figure 2 , Figure 2This is a flowchart of another encrypted data generation method provided in this embodiment of the invention. When the user enters a password (the password consists of letters, numbers, and underscores), the password is obtained. This password is in string form, for example: "abc123.". The obtained password is split into two parts according to a percentage: the first part is 60% and the second part is 40%. For example, the password "abc123." 60% = "abc1", 40% = "23.". The first part of the string is concatenated with the current timestamp in milliseconds to obtain a new string. This new string is used as A in the formula for a hyperboloid of one leaf in quadratic surfaces. For example, the password for 60% is: abc1 + the current timestamp in milliseconds: 11658120633856, resulting in: abc11658120633856. The second part of the string is concatenated with the current timestamp in days to obtain a new string. This new string is used as B in the formula for a hyperboloid of one leaf in quadratic surfaces. For example: 40% of the password: 23. + the current timestamp of days: 319853. The result is: 23.319853. The obtained password string ("abc123.") is converted into a byte stream (dfdfa35afas21asadas9dskjasfas0w236faasas2355z2asdaas2df94sdasd2123123asda1szc.........(the following is omitted)). The byte stream is used as C in the formula for a hyperboloid of one leaf in quadratic surface. A is used as X, B as Y, and C as Z in the formula. The formula is called to obtain H, which is the final encrypted password result.

[0091] Formula for a hyperboloid with one sheet in a quadratic surface:

[0092]

[0093] Compared to existing encryption technologies, the encryption technology in this invention is irreversible, thus providing greater security and ensuring the safety of user identity information, thereby greatly improving data security and user privacy.

[0094] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions.

Besides touch panel 4071, user input unit 407 may also include other input devices 4072. Specifically, other input devices 4072 may include, but are not limited to, physical keyboards, function keys (such as volume control buttons, power buttons, etc.), trackballs, mice, joysticks, etc., which will not be described in detail here.

[0121] Furthermore, the touch panel 4071 can cover the display panel 4061. When the touch panel 4071 detects a touch operation on or near it, it transmits the information to the processor 410 to determine the type of touch event. Subsequently, the processor 410 provides corresponding visual output on the display panel 4061 based on the type of touch event. Although in Figure 4 In this embodiment, the touch panel 4071 and the display panel 4061 are two independent components to realize the input and output functions of the electronic device. However, in some embodiments, the touch panel 4071 and the display panel 4061 can be integrated to realize the input and output functions of the electronic device. The specific implementation is not limited here.

The processor 410 may include one or more processing units; preferably, the processor 410 may integrate an application processor and a modem processor. The application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 410.

[0125] The electronic device 400 may also include a power supply 411 (such as a battery) for supplying power to various components. Preferably, the power supply 411 can be logically connected to the processor 410 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system.

[0126] In addition, the electronic device 400 includes some functional modules not shown, which will not be described in detail here.
