The present invention provides an encryption method based on an energy key table, as shown in Figure 1, comprising:

Step S110: Acquire a plurality of energy data to be encrypted in time series, the energy data to be encrypted at least include energy information to be encrypted and energy labels to be encrypted. The energy data to be encrypted in the present invention can be municipal electric energy, solar energy, wind energy, nuclear energy, water energy, thermal energy, etc., or can be the voltage, current, and electric power respectively included in municipal electric energy, solar energy, wind energy, nuclear energy, water energy, and thermal energy. etc., the present invention does not make any limitation on the form of the energy data to be encrypted. The energy information to be encrypted may be a quantitative value, for example, the quantitative value, voltage value, current value, etc. of the utility power. The energy label to be encrypted may correspond to the name of the energy type. For example, the encrypted energy information is nuclear energy, and the encrypted energy label corresponds to the name of nuclear energy, and so on.

The time series in the present invention can be regarded as a time axis, and the time axis can be synchronized with the natural time. The time series may include multiple moments, and each moment may have different encrypted energy information. The encrypted energy information Can be the sum of the corresponding energy usage up to that moment.

Step S120: Generate a time series table based on the time series and the energy mark to be encrypted, extract the binary code of the time series table, and calculate the first hash value of the binary code of the time series table based on a hash algorithm. Wherein, the hash algorithm in the present invention can map a binary value of any length into a shorter binary value of fixed length, and this small binary value is called the first hash value in this application. The first hash value is a unique and extremely compact numerical representation of a piece of data. In the above manner, the data volume of the time series table can be compressed, so that the subsequent generated multi-dimensional key data volume is small.

Step S130: Calculate according to the data volume value of the energy information to be encrypted to obtain a multi-dimensional key, and calculate the multi-dimensional key of each energy data to be encrypted with a time series by the following formula,

Among them, D is the multi-dimensional key, T ₁ is the quantized value at the start time point of the time series, T ₂ is the quantized value at the end time point of the time series, H is the first hash value, and O _d is the calculated value at the previous time. The multi-dimensional key of the d -th energy data to be encrypted, K _d is the weight of the multi-dimensional key of the d -th energy data to be encrypted calculated at the previous moment, S is the data volume value, and L is the normalized value.

值都是 不同的。数据量值即为数据量，单位可以是字节、千字节、兆字节等等。归一化值可以是预先 设置的，例如说100、1000等等，用于将多维密匙的数字值降低，方便后续的计算。 When calculating the multi-dimensional key, the present invention will fully consider the moment of the time series, the first hash value and the multi-dimensional key of each previous energy data to be encrypted. The above scheme makes the multi-dimensional keys different due to the change of the time dimension even if the energy data to be encrypted obtained at two times are the same. that every moment

The values are all different. The data volume value is the data volume, and the unit can be bytes, kilobytes, megabytes, and so on. The normalized value may be preset, such as 100, 1000, etc., for reducing the digital value of the multi-dimensional key to facilitate subsequent calculations.

Step S140, encrypting the corresponding energy information to be encrypted based on the multi-dimensional key to obtain encrypted energy information, generating an energy key table according to a plurality of multi-dimensional keys, generating energy data to be transmitted according to a plurality of encrypted energy information, The energy key table and the energy data to be transmitted are sent. Because the administrator may need energy data and encrypted energy information in multiple dimensions, it will correspond to multiple multi-dimensional keys. save.

After obtaining the multi-dimensional key, the present invention performs encryption processing on the corresponding energy information to be encrypted according to the multi-dimensional key, and each energy information to be encrypted is set in a one-to-one correspondence with the corresponding multi-dimensional key. Corresponding encrypted energy information is obtained after the encrypted energy information is encrypted according to the multi-dimensional key, and the encrypted energy information at this time has been encrypted. Since there may be multiple multi-dimensional keys, the present invention obtains the energy key table according to the plurality of multi-dimensional keys, and realizes the storage of multiple lost keys through the energy key table, which is convenient for administrators to manage. After obtaining the energy key table and the energy data to be transmitted, the invention can asynchronously send the energy key table and the energy data to be transmitted, so as to prevent the situation that the energy key table and the energy data to be transmitted are stolen by others at the same time and cause secret leakage .

In a possible embodiment, the present invention can calculate the weight of the multi-dimensional key of the d -th energy data to be encrypted at the previous moment by the following formula, including:

是以计算K _d 的时刻为基准，先前第一个时刻的待加密能源信息的数据量 值；

是以计算K _d 的时刻为基准，先前第二个时刻的待加密能源信息的数据量值；

是以 计算K _d 的时刻为基准，先前第三个时刻的待加密能源信息的数据量值，A为先前第一个时刻 的待加密能源信息的数据量值的权重值，B为先前第二个时刻的待加密能源信息的数据量 值的权重值，C为先前第二个时刻的待加密能源信息的数据量值的权重值。 in,

is the data volume value of the energy information to be encrypted at the first previous moment based on the moment when K _d is calculated;

is the data volume value of the energy information to be encrypted at the second previous moment based on the moment when K _d is calculated;

Based on the moment of calculating K _d , the data volume value of the energy information to be encrypted at the third previous moment, A is the weight value of the data volume value of the energy information to be encrypted at the previous first moment, B is the previous second The weight value of the data amount value of the energy information to be encrypted at one time, C is the weight value of the data amount value of the energy information to be encrypted at the second previous time.

For example, if the time for calculating K _d is 11:00:00 on September 10, 2020, the benchmark is 11:00:00 on September 10, 2020. At this time or get the previous first moment (12:00:20 on August 10, 2020), the second moment (8:10:00 on July 23, 2020) and the third moment (June 2020) 15:40:30 on the 17th), the first time, the second time and the third time are respectively the time when energy encryption information is generated after obtaining the energy data to be encrypted. The first moment can be the previous moment closest to the benchmark, and the first moment at this time can be regarded as the latest generation moment of energy encryption information before the current generation of energy encryption information; the second moment can be the previous generation moment of the first moment. The most recent moment, the second moment at this time can be regarded as the generation moment of the most recent energy encryption information before the energy encryption information is generated at the first moment, and so on, the corresponding third moment and the corresponding third moment are obtained. The data volume value of the energy information to be encrypted.

When calculating the weight of the multi-dimensional key of the d -th energy data to be encrypted, the present invention obtains the data volume value of the energy information to be encrypted at the previous three times of the d -th energy data to be encrypted. The data volume value of the energy information to be encrypted is used to obtain the weight of the multi-dimensional key of each energy data to be encrypted. Through the calculation in the above manner, the weights of the multi-dimensional keys of each energy data to be encrypted are different, so that the multi-dimensional keys generated by the present invention are unique in each dimension.

对K _d 的影响 会大于

对K _d 的影响，使得K _d 能够根据以往的待加密能源信息的数据量值进行改变。 In addition, the weights of the data values of the energy information to be encrypted in the previous three moments can be pre-configured, for example, A is 1.1, B is 1, and C is 0.9. The specific values are not limited in the present invention, but it is necessary to ensure that A > B > C so that

The effect on K _d will be greater than

The influence on K _d enables K _d to be changed according to the previous data amount of energy information to be encrypted.

In a possible implementation, step S110 includes:

Step S1101: Receive selected information, where the selected information at least includes target time period information and target energy information. In the present invention, the energy data will be selected first, that is, the administrator will select the data at the data terminal where the energy data is stored. The target time period information may be from 00:00:00 on December 1, 2020 to 23:59:59 on December 31, 2020. The target energy information may be voltage information, current information, nuclear energy information, and the like.

Step S1102 , selecting the energy data to be encrypted corresponding to the duration series in the energy data to be encrypted in multiple categories based on the target energy information. For example, if the target energy information is nuclear energy, then the corresponding duration time series of energy data to be encrypted will be selected. The duration time series may start from the initial collection time, for example, the initial collection time may be January 2015. At 00:00:00 on the 1st, the time axis of the collection time at this time is from 00:00:00 on January 1, 2015 to the present. At this time, the time series and time axis corresponding to nuclear energy will be obtained.

Step S1103: Select a time series of energy data to be encrypted in a time series of the energy data to be encrypted based on the target time period information. The present invention will select from 00:00:00 on January 1, 2015 to the current time series and time axis, from 00:00:00 on December 1, 2020 to 23:59:59 on December 31, 2020 The energy data to be encrypted corresponding to the time period of seconds, the energy data to be encrypted at this time is the data required by the management personnel.

Through steps S1101 to S1103, the present invention can quickly extract the energy data to be encrypted.

In a possible implementation, step S120 includes:

Get each moment value in the time series. The time series in the present invention may have multiple time values.

The year, month, and day information in the extracted time value is converted according to the first preset method, so that it becomes the first quantity information. The first preset method can be as follows. For example, on December 31, 2020, it can be converted into 6365, of which 6 corresponds to 2020. Because the time axis starts from 2015, it is considered that 2015 is 1, and then the year 2020 is 1. is 6. Among them, there are 365 days in a year, and if December 31 is the last day of the year, it is considered to be 365. In the above manner, the year, month and day can be quantified so that they can be compared quantitatively.

The hour, minute and second information in the extracted time value is converted according to the second preset method, so that it becomes the second quantity information. The second preset mode can be as follows, for example, 23:59:59 can be quantified as 86400, there are 24 hours in a day, each hour has 60 minutes, and each minute has 60 seconds, then a day has 86400 seconds, so the present invention Hours, minutes, and seconds are quantified into a single value.

A quantized time value is generated based on the first quantity information and the second quantity information. For example, at 23:59:59 on December 31, 2020, the quantized value is 636586400.

Wherein, the quantized value T ₁ at the start time point of the time series and the quantized value T ₂ at the end time point of the time series can be respectively quantized according to the method of step S120 .

A time series table is generated by combining the quantized time value and the corresponding energy mark to be encrypted.

Through the above technical solution, all the time values in the time series table can be quantified, so that the time series table is a numerical value when being processed, which is convenient for calculation and statistics.

In a possible implementation manner, generating a time series table from the quantized time value and the corresponding energy label to be encrypted includes:

The energy label to be encrypted is quantized based on a preset correspondence relationship to obtain a quantized energy label to be encrypted, wherein the preset correspondence relationship is a correspondence between the energy label to be encrypted and the quantized value of the energy label to be encrypted. The energy token to be encrypted can be the name of the energy. In this step, the preset corresponding relationship may be set in advance, including the corresponding relationship between a plurality of energy markers to be encrypted and their corresponding quantized values, and quantization processing is performed on the energy markers to be encrypted according to the preset preset corresponding relationship, for example, , the pre-corresponding quantized value of nuclear energy (energy tag to be encrypted) is 100 (the quantized value of the energy tag to be encrypted), the pre-corresponding quantized value of wind energy is 200, the pre-corresponding quantized value of voltage is 300, and the pre-corresponding quantized value of current is 400, quantify the energy token to be encrypted in the above manner. Through the above methods, the quantitative processing of the encrypted energy target is realized.

A time series table is generated by combining the quantized time value and the quantized energy label into a quantity value. After the present invention quantifies the time value and the energy mark respectively, all the information and data in the time series table are quantized values, which is convenient for subsequent storage and processing based on the hash algorithm, so that the processing speed of the technical solution of the present invention is faster. quick.

In a possible implementation manner, the encrypted energy information obtained by encrypting the corresponding energy information to be encrypted based on the multi-dimensional key includes:

Add the multi-dimensional key to the preset general compression path to generate an encrypted compression path. The present invention can obtain the encrypted compression path according to the preset compression path after obtaining the multi-dimensional key, and perform encryption and compression processing on the energy data and the energy information to be encrypted according to the encrypted compression path.

A reverse decryption and decompression path is generated according to the encrypted compression path, and the decryption and decompression path performs a decompression process in response to the multi-dimensional key. The invention generates a corresponding decryption and decompression path while obtaining the encryption and compression path, and the user can decrypt and pressurize the encrypted energy information and energy data according to the decryption and decompression path.

The encrypted energy information is obtained by encrypting the energy information to be encrypted based on the encryption compression path.

Through the above technical solutions, the present invention combines the general compression path and the multi-dimensional key to obtain the encryption path, and realizes the encryption processing of the energy information to be encrypted. While convenient and fast, it ensures that each encrypted energy information has a different multi-dimensional key.

In a possible implementation, it also includes:

Destruction logic is provided in the decryption and decompression path. In the actual use and operation process, the encrypted encrypted energy information may be transferred to other people through various channels, so the present invention needs to set a destruction logic, so that other people who do not have the multi-dimensional key cannot open the encrypted energy information. , and data corruption can be performed. For example, the destruction logic is to scramble the corresponding source code in the encrypted energy information, so that it cannot be recovered or restored. The specific implementation of the destruction logic can be the prior art, and the present invention will not elaborate.

When the number of multi-dimensional key errors received by the decryption and decompression path exceeds a preset value, the encrypted energy information is destroyed according to the preset destruction logic based on the destruction logic. The default value of the number of errors is 3. When the number of errors in the multi-dimensional key exceeds 3 times, it is determined that the person who wants to open the encrypted energy information does not have the corresponding authority, so it is destroyed according to the preset destruction logic at this time.

Through the above methods, the security of energy data is guaranteed. Even if the encrypted energy information is obtained by others, it cannot be opened by means of multiple attempts.
