Description
Technical Field

These important operations can only be performed when the user has entered the correct password or performed the correct combination operation (successful unlock).
Existing passwords typically include fixed passwords and passwords that can be manually modified. The fixed password (such as '111') is fixed and unchangeable, so the password of the type has the defects of easy cracking and easy embezzlement, and the password which can be modified manually means that a user needs to update the password manually, and if the password is modified infrequently, the password is also at risk of cracking. If the password is modified too frequently, the memory burden of the user is caused, and the situation that the user forgets the password is easy to occur. If a certain electrical system contains a plurality of identical electrical devices, the uncertainty of manually modifying the password may cause the password of each electrical device to be different, which also causes trouble in managing the electrical system.

Fig. 1 shows a schematic implementation flow diagram of a password generation method for an electrical device provided by this embodiment.
As shown in fig. 1, the password generation method provided by the present embodiment preferably obtains real-time data of preset natural variables related to the electrical device in step S101. Specifically, in this embodiment, the preset natural variables preferably include device internal characteristic variables and device environment characteristic variables. The internal characteristic variable of the equipment is a variable representing physical characteristics of the electrical equipment and/or internal devices, and the environmental characteristic variable of the equipment is a variable representing environmental information of the electrical equipment.
In this embodiment, the environment characteristic variable of the device may preferably be a commonly used variable that can represent environment information and is in daily contact with the device. For example, the device environment feature variables may include: year, month, date, hour, minute, second, week, temperature, and humidity. The device internal feature variables may include: brightness, volume, voltage, current, weight, and volume. The internal characteristic variable of the device may be an existing characteristic parameter inside the device, or may be a characteristic parameter obtained by a specific detection device or external communication.
For example, if the processor used by the electrical device has a built-in real-time clock RTC, the method may directly acquire clock data such as year data, month data, and hour data of the current time from the built-in RTC of the processor as real-time data of the preset natural variable in step S101.
For another example, if the electrical device includes an input-side voltage sensor, the method may acquire the input-side voltage at the current time by connecting to the voltage sensor in step S101, and use the voltage value of the input-side voltage as real-time data of the preset natural variable.
For another example, if the electrical device can acquire temperature data and humidity data by communicating with the environment detector, in step S101, the method may use the data values of the temperature data and humidity data acquired at the current time as real-time data of the preset natural variables.
It should be noted that, in different embodiments of the present invention, the feature parameters included in the device environment feature variables and/or the device internal feature variables may include only one or some of the above listed items, or may include other reasonable items not listed.
Of course, in other embodiments of the present invention, the preset natural variables may only include the device internal characteristic variables or the device environment characteristic variables, or may include other reasonable variables not listed, according to actual needs, and the present invention is not limited thereto.
As shown in fig. 1, after obtaining the real-time data of the preset natural variable, the method preferably performs data processing on the real-time data of the preset natural variable in step S102, so as to extract the password source data for generating the dynamic password from the real-time data.
Specifically, in this embodiment, the method preferably extracts the password source data from the real-time data according to a preset password source data generation model in step S102. Wherein, the preset cipher source data generation model preferably includes: a numerical extraction model, a character extraction model and a data conversion model.
In this embodiment, in the numerical extraction model, the method preferably performs numerical extraction on the data value of the real-time data of the preset natural variable acquired in step S101 to obtain an effective numerical value, and then uses the effective numerical value as the password source data.
For example, if the temperature data acquired by the method in step S101 is 21 ℃, the humidity data is 56%, and the current time is 12:09:45, then the method may extract the ones bit value "1" of "21", the ones bit value "6" of "56", and the ones bit value "2" of "12" as the password source data based on the value extraction model in step S102.
In the character extraction model, in this embodiment, the method preferably obtains the english conversion data of the real-time data of the preset natural variables obtained in step S101, then extracts valid characters from the english conversion data, and then uses the valid characters as password source data.
For example, if the month at the current time is "12" acquired in step S101, the method first converts to obtain the corresponding english character "December", then extracts the english abbreviation "Dec" from the english character "December", and uses the english abbreviation "Dec" as the password source data.
In the data conversion model, in this embodiment, the method preferably converts the real-time data of the preset natural variables obtained in step S101 into the password source data based on the preset password conversion rule. It should be noted that the preset cipher conversion rule may be preset, and represents the relevant conversion relationship between different characters or data.
For example, if the current value of the electrical device acquired by the method in step S101 is 50A and the character corresponding to "50" in the preset password conversion rule is "&", then the method may obtain the password source data "&" from the current value "50A" in step S102.
Of course, in other embodiments of the present invention, the preset cryptographic source data generation model may include only one or some of the above listed items, or may include other reasonable items not listed according to actual needs.
For example, in one embodiment of the invention, the method may combine at least two of a numerical extraction model, a character extraction model, and a data conversion model simultaneously to generate the cryptographic source data. As shown in fig. 2, in this embodiment, the method preferably extracts a valid numeric value and/or a valid character from the real-time data according to a numeric extraction model and/or a character extraction model in step S201, and then converts the valid numeric value and/or the valid character based on a data conversion model in step S202 to obtain the password source data.
Specifically, for example, the current voltage value of the electrical device acquired in step S101 by the method is 380V, the month at the current time is "12", the valid value "8" can be extracted according to the value extraction model, the valid character "Dec" can be extracted according to the character extraction model, the data corresponding to the valid value "8" is "@" based on the data conversion model, and then the password source data finally obtained by the method is "@" and "Dec".
Of course, in other embodiments of the present invention, the method may also determine the password source data according to the real-time data of the preset natural variables based on other reasonable combinations of the numerical extraction model, the character extraction model and the data conversion model.
As shown in fig. 1 again, in this embodiment, after obtaining the password source data, the method preferably generates a dynamic password for the electrical device according to the password source data in step S103. Specifically, in this embodiment, the method preferably performs numerical calculation and/or combination on the above-mentioned password source data in step S103, so as to generate a dynamic password for the electrical device.
For example, in the method, the cipher source data extracted in step S102 are "1", "2", and "6", and in step S103, the dynamic cipher "9" can be obtained by adding the cipher source data.
For another example, the password source data obtained by the method in step S102 are "1", "2", and "6", and the method may combine the password source data to combine "1", "2", and "6" in the current order in step S103, so as to obtain the dynamic password "126".
For another example, the cipher source data obtained by the method in step S102 are "1", "2", and "6", and the method in step S103 may first perform an operation on part of the data (e.g., perform an operation on "1" and "6" to obtain "6"), and then combine the obtained data (e.g., "6") and the remaining data (e.g., "2") according to a preset order (e.g., a reverse order or a forward order), so as to obtain the dynamic cipher "26".
For another example, the password source data obtained in step S102 is "Dec", and the method may combine the password source data with a predetermined symbol (e.g., "%") in step S103, so as to obtain a dynamic password of "Dec%".
As another example, the method may obtain the password source data of "8" and "&" in step S102, and the method may combine the password source data with a preset constant (e.g., "4") to obtain the dynamic password of "8 & 4" in step S103.
It should be noted that, in different embodiments of the present invention, the specific data of the preset symbol and the preset constant used in the process of generating the dynamic password may be configured into different reasonable value data according to actual needs, and the present invention is not limited to this specific data.
The invention also provides a password generation device for the electrical equipment. Fig. 3 shows a schematic mechanism diagram of the password generation apparatus in the present embodiment.
As shown in fig. 3, the password generation apparatus provided in this embodiment preferably includes: a real-time data acquisition module 301, a password source data extraction module 302 and a dynamic password generation module 303. The real-time data acquiring module 301 is configured to acquire real-time data of preset natural variables related to the electrical device.
The password source data extraction module 302 is connected to the real-time data acquisition module 301, and is capable of performing data processing on the real-time data of the preset natural variable transmitted by the real-time data acquisition module 301, so as to extract the password source data from the real-time data, and send the password source data to the dynamic password generation module 303 connected thereto.
The dynamic password generation module 303 may generate a dynamic password for the current electrical device according to the password source data transmitted by the password source data extraction module 302.
In this embodiment, the principle and the process of the real-time data obtaining module 301, the password source data extracting module 302 and the dynamic password generating module 303 for implementing their respective functions are similar to those described in the above steps S101 to S103, and therefore detailed descriptions of the real-time data obtaining module 301, the password source data extracting module 302 and the dynamic password generating module 303 are omitted here.
As can be seen from the above description, the method and apparatus for generating a password for an electrical device according to the present invention enable the password to change naturally by introducing real-time data of preset natural variables related to the electrical device, which does not require manual intervention as in the prior art. Meanwhile, the method and the device carry out simple processing and subsequent simple calculation or combination through the real-time data of the preset natural variables, so that the complexity of the finally obtained dynamic password is improved, and the anti-cracking capability of the dynamic password is improved.

The method and the device can reduce the risk of password cracking and can also ensure that the password change does not depend on manual modification, which has uncertainty and randomness.
