Specifically, the encryption table is mainly implemented by using character block chainIs the most recent block of (c)As a reference, transcoding each bit code in the code string according to different encryption modes; in practical use, although the encryption table is fixed and the encryption scheme is limited, since the reference of the encryption scheme is a character blockCharacter blocks in a character block chainIs variable, and correspondingly, the transcoded data is also variable, which can realize a relatively dynamic transcoding effect.
In particular, the embodiment of the invention is based onThe built predefined corresponding rule is specifically expressed byCharacter block as anchor pointSelection rules, particularly due to character blocksIs 0 or 1, theoretically, character blockchainA plurality of character blocks with character information of 0 and a plurality of character blocks with character information of 1 exist in the memory; character blockThe selection rule is understood as a selection manner of selecting a specific one of a plurality of character blocks of the same character information.
For example, the correspondence rule may be to select a distance character blockThe most recent character block having the same character information is used as the corresponding block, for example, the 1 st bit in the code string is encoded as 0, referring to the character block chain shown in fig. 2, if the character blockIs a distance character blockThe nearest block with character information of 0 is then used as the character block under the corresponding ruleAs a corresponding block corresponding to the 1 st bit code.

Specifically, according to the description of the two corresponding rules, the corresponding rules can be basically analogized to a known line segment, and a means for selecting an intermediate point in the line segment according to a specific mode based on the end points of the line segment; the method can be a function means, an additional condition means and the like, can be selected according to the requirement in the prior art in the implementation, and can be realized by only meeting the basic definition of the function, namely, giving a specific input to the function and having only corresponding output.
With this embodiment, each bit code is processed by the corresponding rule, and then the character block chain is processedHas a corresponding character block.
S103: based on presetAccording to the mapping relation of the key characterForm location of (c)Selecting corresponding number information in the encryption tableAnd according to the number informationSelect the corresponding firstThe seed encryption scheme is used as the target encryption scheme, wherein,；
specifically, form locationAnd numbering informationThe two data formats are the same, and the two data formats can be converted by adopting a proper mapping mode in the prior art, further, in view of the fact that the data format is similar to two-dimensional coordinates, the related two-dimensional coordinate mapping means in the prior art can also be applied to the embodiment of the invention. In particular, according to the general application scenario, the table position is theoreticallyThe number of (2) is several orders of magnitude greater than the number of encryption modes, so that the mapping relation can be understood as a coordinate compression mode or a coordinate system mapping mode, and the method can be realized by referring to the related prior art in practical implementation.
Specifically, according to the mapping relation, according to the key charactersForm location of (c)The corresponding target encryption scheme can be selected.
