The invention provides an encryption method based on an energy key table, as shown in figure 1, comprising the following steps:
step S110, a plurality of to-be-encrypted energy data with a time sequence are obtained, wherein the to-be-encrypted energy data at least comprise to-be-encrypted energy information and to-be-encrypted energy marks. The energy data to be encrypted in the invention can be commercial power, solar energy, wind energy, nuclear energy, water energy, heat energy and the like, and can also be voltage, current, electric power and the like respectively included by commercial power, solar energy, wind energy, nuclear energy, water energy and heat energy, and the invention does not limit the form of the energy data to be encrypted. The energy information to be encrypted may be a quantity value, such as a quantity value, a voltage value, a current value, and the like of the commercial power. The energy source mark to be encrypted may be a name corresponding to a type of the energy source, for example, if the encrypted energy source information is the nuclear energy, the encrypted energy source mark corresponds to the name of the nuclear energy, and so on.
The time sequence in the present invention can be regarded as a time axis, the time axis can be synchronized with the natural time, the time sequence includes a plurality of moments, each moment may have different encrypted energy information, and the encrypted energy information may be the sum of corresponding energy usage amounts before the moment.
And S120, generating a time sequence table based on the time sequence and the energy mark to be encrypted, extracting the binary codes of the time sequence table, and calculating a first hash value of the binary codes of the time sequence table based on a hash algorithm. The hash algorithm in the present invention can map a binary value of any length to a shorter binary value of a fixed length, and this small binary value is referred to as the first hash value in the present application. The first hash value is a unique and extremely compact representation of a piece of data. By the method, the data size of the time sequence list can be compressed, so that the subsequently generated data size of the multi-dimensional key is small.
Step S130, calculating according to the data quantity value of the energy information to be encrypted to obtain a multi-dimensional key, calculating the multi-dimensional key of each energy data to be encrypted with a time sequence through the following formula,
wherein,Dis a multi-dimensional key, and is characterized in that,T 1is a quantized value of a starting time point of the time series,T 2is a quantized value of the end time point of the time series,His the first hash value of the first set of values,O d calculated for the previous momentdA multi-dimensional key of the energy data to be encrypted,K d calculated for the previous momentdThe weight of the multidimensional key of the energy data to be encrypted,Sin order to be a magnitude of the data,Lis a normalized value.
When the multi-dimensional key is calculated, the time sequence moment, the first hash value and the multi-dimensional key of each previous energy data to be encrypted are fully considered. According to the scheme, even if the energy data to be encrypted obtained at two moments are the same, the multi-dimensional key is different due to the change of the time dimension. I.e. at each moment
The values are all different. The data amount is the data amount, and the unit can be byte, kilobyte, megabyte, etc. The normalization value may be preset, for example, 100, 1000, etc., and is used to reduce the numerical value of the multi-dimensional key for facilitating subsequent calculations.
Step S140, encrypting the corresponding energy information to be encrypted based on the multi-dimensional keys to obtain encrypted energy information, generating an energy key table according to the multi-dimensional keys, generating energy data to be transmitted according to the encrypted energy information, and sending the energy key table and the energy data to be transmitted. Because the administrator may need energy data and encrypted energy information of multiple dimensions, the administrator can correspond to multiple multi-dimensional keys.
After the multi-dimensional key is obtained, the corresponding energy information to be encrypted is encrypted according to the multi-dimensional key, and each piece of energy information to be encrypted is arranged in one-to-one correspondence with the corresponding multi-dimensional key. And encrypting the energy information to be encrypted according to the multi-dimensional key to obtain corresponding encrypted energy information, wherein the encrypted energy information is encrypted at the moment. Because the multidimensional keys can be multiple, the energy key table can be obtained according to the multidimensional keys, multiple lost storages are realized through the energy key table, and the management of an administrator is facilitated. After the energy key table and the energy data to be transmitted are obtained, the energy key table and the energy data to be transmitted can be asynchronously transmitted, so that the condition that the energy key table and the energy data to be transmitted are simultaneously stolen by others to cause secret leakage is prevented.
In one possible embodiment, the present invention may calculate the previous time instant by the following formuladThe weight of the multidimensional key of the energy data to be encrypted comprises the following steps:
wherein,
is to calculateK d The time of the energy source information to be encrypted is taken as a reference, and the data quantity value of the energy source information to be encrypted at the previous first time is taken as a reference;
is to calculateK d The time of the energy source information to be encrypted is taken as a reference, and the data quantity value of the energy source information to be encrypted at the previous second time is taken as a reference;
is to calculateK d The time of the energy source information to be encrypted at the third previous time is taken as a reference, the data quantity value of the energy source information to be encrypted at the third previous time is taken as a reference,Athe weight value of the data quantity value of the energy source information to be encrypted at the previous first moment,Bthe weighted value of the data quantity value of the energy information to be encrypted at the previous second moment,Cfor the energy to be encrypted at the second previous momentA weight value of a data magnitude of the source information.
For example, calculateK d When the time of (1) is 9/10/11/00 seconds in 2020, the reference is 9/10/11/00/seconds in 2020. At this time, the first time (8/10/12/00/20 seconds in 2020), the second time (7/23/8/10/00 seconds in 2020), and the third time (15/6/17/15/40/30 seconds in 2020) are acquired, and the first time, the second time, and the third time are respectively the times at which the energy encryption information is generated after the energy data to be encrypted is acquired. The first time may be the time closest to the reference in the past, and the first time at this time may be regarded as the time of generating the most recent primary energy encryption information before the energy encryption information is generated this time; the second time may be the latest previous time of the first time, and the second time may be regarded as the latest generation time of the primary energy encryption information before the energy encryption information is generated at the first time, and so on, to obtain the corresponding third time and the data quantity value of the energy information to be encrypted corresponding to the third time.
The invention is in calculatingdThe weight of the multidimensional key of the energy data to be encrypted is obtaineddAnd the data quantity values of the energy source information to be encrypted at the previous three moments of the energy source data to be encrypted are used for obtaining the weight of the multi-dimensional key of each energy source data to be encrypted according to the data quantity values of the energy source information to be encrypted at the previous three moments. Through the calculation in the mode, the weight of the multi-dimensional key of each energy source data to be encrypted is different, so that the multi-dimensional key generated by the method has uniqueness in each dimension.
Furthermore, the weights of the data quantity values of the energy information to be encrypted at the previous three moments can be configured in advance, for exampleA1.1 percent of,BIs 1,CIs 0.9, the specific value is not limited in the present invention, but it is guaranteedA＞B＞CSo that
To pairK d Will have an influence greater than
To pairK d Is caused by the influence ofK d The data quantity value of the energy information to be encrypted in the past can be changed.
In one possible embodiment, step S110 includes:
step S1101, receiving selected information, wherein the selected information at least comprises target time period information and target energy information. According to the invention, the energy data is firstly selected when being transmitted, namely, the administrator selects the data at the data end for storing the energy data. The target time period information may be 00 min 00 s at 1 st 00 h/1 st 2020 to 59 min 59 s at 23 st at 12 st 31 st 2020. The target energy information may be voltage information, current information, nuclear energy information, and the like.
Step S1102, selecting corresponding energy data to be encrypted with a duration sequence from the energy data to be encrypted of multiple categories based on the target energy information. For example, if the target energy information is nuclear energy, the energy data to be encrypted of the corresponding duration sequence is selected, the duration sequence may be started from the initial acquisition time, for example, the initial acquisition time may be 2015 year 1 month 1 day 00 hour 00 minute 00 second, and the time axis of the acquisition time at this time is 2015 year 1 month 1 day 00 minute 00 second to the present. At this time, a time sequence and a time axis corresponding to the nuclear energy are obtained.
Step S1103, selecting a time series of energy data to be encrypted from the energy data to be encrypted based on the target time period information. According to the method, the energy data to be encrypted corresponding to the time period from 00 min 00 s at 1 month and 1 day in 2015 to 00 min 00 s at 1 month and 1 day in 2020 to 59 min 59 s at 23 months 31 and 31 days in 2020 is selected on the time axis, and the energy data to be encrypted is the data required by the administrator.
Through the steps S1101 to S1103, the present invention can rapidly extract the energy data to be encrypted.
In one possible embodiment, step S120 includes:
each time instant value in the time series is obtained. The time series in the present invention will have multiple time values.
The year, month and day information in the extracted time value is converted according to a first preset mode to become first quantity information. The first preset mode may be, for example, 12/31/2020, which may be converted to 6365, where 6 corresponds to 2020, and since the time axis starts from 2015, 2015 is considered as 1, and then 2020 is 6. Of these, 365 days of a year, 12 months 31 is the last day of the year, and it is deemed 365. In the above manner, the year, month and day can be quantified so that it can be compared in quantity.
And converting the time, minute and second information in the extracted time value according to a second preset mode to form second quantity information. The second predetermined manner may be that, for example, 23 hours 59 minutes 59 seconds can be quantified as 86400, 24 hours a day, 60 minutes each hour, and 60 seconds per minute, 86400 seconds a day, so the present invention quantifies the time, minute, and second information as a numerical value.
And generating a quantized time value based on the first quantity information and the second quantity information. For example, 59 minutes 59 seconds at 31/23/12/2020, the quantified value is 636586400.
Wherein the quantized value of the starting time point of the time sequenceT 1Quantized value of the end time point of the time seriesT 2Quantization may be performed in the manner of step S120, respectively.
And generating a time sequence table by the quantized time value and the corresponding energy source mark to be encrypted.
Through the technical scheme, all time values in the time sequence list can be quantized, so that the time sequence list is numerical values when being processed, and calculation and statistics are facilitated.
In one possible embodiment, the step of generating the time sequence table by the quantized time value and the corresponding energy source mark to be encrypted includes:
and quantizing the energy marker to be encrypted based on a preset corresponding relationship to obtain a quantized energy marker to be encrypted, wherein the preset corresponding relationship is the corresponding relationship between the energy marker to be encrypted and the quantized value of the energy marker to be encrypted. The energy source indicia to be encrypted may be the name of the energy source. In this step, the preset corresponding relationship may be set in advance, and includes a corresponding relationship between a plurality of energy markers to be encrypted and quantized values corresponding to the energy markers, and the energy markers to be encrypted are quantized according to the preset corresponding relationship, for example, the quantized value corresponding to the nuclear energy (energy marker to be encrypted) in advance is 100 (quantized value of energy marker to be encrypted), the quantized value corresponding to the wind energy in advance is 200, the quantized value corresponding to the voltage in advance is 300, and the quantized value corresponding to the current in advance is 400, and the energy markers to be encrypted are quantized in this way. Through the above manner, the quantization processing of the energy target to be encrypted is realized.
