Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
The embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Example 1:
as shown in fig. 1, an embodiment of the present disclosure provides a method for encrypting grid-connected test data, including the following steps:
s01, acquiring test data of the new energy remote grid connection;
s02, compressing the test data;
s03, encrypting the compressed test data;
and S04, transmitting the encrypted test data by using the security authentication algorithm of the VPN private channel.
By adopting the method for encrypting the data in the grid-connected test, which is provided by the embodiment of the disclosure, aiming at the problem of safety, namely privacy protection of various data in the process of the new energy remote grid-connected test, the data is compressed, coded and decoded to finish high-efficiency transmission, so that the method has good confidentiality and accuracy, and can meet the requirement of encrypting the big data in the new energy remote grid-connected test.
In some embodiments, encrypting the compressed test data comprises:
and carrying out sectional encryption on the compressed test data, wherein the sectional encryption is to select key frame data from the compressed test data and encrypt the key frame data.
Optionally, the selecting key frame data from the compressed test data includes: selecting an intra-frame prediction strip in the compressed test data; selecting an intra prediction block from an intra prediction slice; and selecting sub-blocks with the number of non-zero transformation coefficients not being 0 from the intra-frame prediction blocks, wherein the selected sub-blocks with the number of non-zero transformation coefficients not being 0 are the key frame data.
Optionally, the selecting key frame data from the compressed test data includes: selecting a forward prediction band, a bidirectional prediction band and an intra-frame prediction band in the compressed test data; selecting an intra-frame prediction block from the selected forward prediction strip, the bidirectional prediction strip and the intra-frame prediction strip; and selecting sub-blocks with the number of non-zero transformation coefficients not being 0 from the intra-frame prediction blocks, wherein the selected sub-blocks with the number of non-zero transformation coefficients not being 0 are the key frame data.
Comparing the two methods for selecting key frame data from the compressed test data, the first method can not meet the requirement of visual invisibility well because the inter-frame prediction band still contains the intra-frame prediction block, but the first method is simple to operate and can be used in occasions with lower safety requirements; the second approach is relatively complex, but visual invisibility may be better satisfied.
As shown in FIG. 2, in some embodiments, the compressed test data is encrypted, including:
encrypting the compressed test data by adopting a packet hybrid encryption algorithm, wherein the packet hybrid encryption algorithm comprises the following steps:

and placing and combining the 16 key primitives according to the positions of the arranged index numbers to obtain a 64-bit original key.
It is understood that secrecy is manifested in the plaintext sensitivity and key sensitivity of the encryption algorithm. Plaintext sensitivity and key sensitivity are important judgment criteria for the quality of an encryption algorithm. The plaintext sensitivity of the block hybrid encryption algorithm depends on the position of the block where the changed plaintext is located, that is, once the plaintext changes, the encrypted ciphertext corresponding to the segment containing the changed plaintext will change accordingly.
