Energy usually refers to coal, oil, natural gas, biomass energy, electricity, heat, and other resources that obtain useful energy directly or through processing and conversion; a large amount of energy data will be generated in the process of energy measurement, and these energy data need to be stored. In the current energy data storage process, it is generally stored directly in the database. Due to the huge amount of data, it is difficult to encrypt and store it through conventional encryption methods. Therefore, a secure energy data storage method with higher security is urgently needed.

The present invention randomly acquires pictures and uses the pictures as the basis for encrypting energy data, thereby performing multi-layer segmentation of the data to be encrypted, and then reorganizing the divided data to be encrypted in a specific order. Since the content of the pictures is random, therefore The recombined data obtained based on the picture as the encryption basis is also random, which effectively guarantees the encryption security of the data.

In this step, the header data is intercepted from the data to be encrypted. First, the header data is intercepted. When intercepting, the proportion of the interception is determined according to the random encrypted data image set. Then the proportion of the obtained header data is also random, and then the interception Afterwards, the data to be encrypted is divided into N groups of data to be processed, that is, divided into 8 groups of data to be processed. If the header data is intercepted by a%, then the proportion of data to be processed is (1- a%)/N, and then treated The processed data is evenly divided. For example, the 8 groups of data to be processed are a, b, c, d, e, f, g, and h respectively, and the data to be processed by a is divided into M data blocks, and the number of each data block is are a ₁ , a ₂ ..., a _M ; the proportion of the header data does not exceed 1% of the data to be encrypted.

In this step, N groups of data block groups are reassembled according to N groups of encrypted data sources, and converted into hexadecimal according to the specific length data in N groups of encrypted data sources, and three-digit binary data can represent 8 numbers. Therefore, a set of data of a specific length in each group of encrypted data sources can be converted into a hexadecimal number, and the range is 0-7, then the data of a specific length corresponding to the same number in N groups of encrypted data sources corresponds to 8 hexadecimal numbers For example, the specific length data corresponding to the same number in N groups of encrypted data sources are converted into hexadecimal numbers of 2, 3, 5, 1, 7, 6, 2 and 0, and the encrypted data sources of N groups are related to N One-to-one correspondence between groups of data blocks, then according to 2, 3, 5, 1, 7, 6, 2 and 0 to determine the arrangement position of the data blocks corresponding to the same number in N groups of data block groups, for example, in N groups of encrypted data sources The data of a specific length corresponding to the same number in hexadecimal are 2, 3, 5, 1, 7, 6, 2, and 0 respectively, and the data blocks corresponding to the same number in N groups of data blocks are a1, b1, c1 respectively , d1, e1, f1, g1, and h1, after reorganization, the data blocks corresponding to the same number in N groups of data block groups are exchanged according to 2, 3, 5, 1, 7, 6, 2, and 0, that is, a1 is the second , b1 No. 3, c1 No. 5, d1 No. 1, e1 No. 7, f1 No. 6, g1 No. 2, h1 No. 0, for repeated numbers, arrange the corresponding data blocks to the end, and the order of arrangement is h1, d1, a1, b1, c1, f1, e1, and g1, it can be seen at this time that the data blocks between different data block groups have been reorganized, and the reorganized data will be published on the blockchain, header data and random encrypted data The image set is distributed and stored on the local server. At this time, the reorganized data is public content. Even if it is downloaded, the content cannot be directly obtained.
