The first embodiment of the present invention, an encryption transmission method for reduced codec according to an embodiment of the present invention, as shown in fig. 1, includes the following specific steps:
step S1, acquiring a plaintext to be transmitted;
s2, coding the plaintext to be transmitted by using the configured template data to obtain a corresponding ciphertext;
s3, transmitting the ciphertext;
and S4, after the transmission is completed, decoding the ciphertext by using the configured template data.
The method provided by the invention will be described in more detail below in connection with fig. 1.
Step S1, obtaining a plaintext to be transmitted.
In this embodiment, the plaintext to be transmitted is usually a text segment in text form, which includes words, letters, symbols, and numerals, which is not limited herein.
And S2, coding the plaintext to be transmitted by using the configured template data to obtain a corresponding ciphertext.
In this embodiment, the template data includes a ciphertext template, a plurality of basic data tables, and a comparison table.
Referring to fig. 3, wherein the basic data table includes names arranged in a preset order and corresponding in-table codes; the comparison table generates a corresponding relation with the table type of the basic data table according to the name corresponding to the table internal code, and generates a comparison code according to the serial number of the internal code in the preset sequence of the basic data table; the ciphertext template may be used to characterize the format of the ciphertext.
Illustratively, the ciphertext template may be "A at B at C D", with corresponding ciphertext encoding. A, B, C, D characterizes the table type of the basic data table, specifically, a is basic data table a, B, C, D, and so on. Further, for example, the a contains names arranged according to a preset sequence, for example, "Zhang san, li Si, wang Wu", in one possible embodiment, the names may be arranged according to the sequence of 1-Zhang san, 2-Li Si, 3-Wang Wu, where the sequence number of the sequence ranking is the comparison code, and each name is configured with a corresponding in-table code.
In order to facilitate the inquiry, the comparison table can be configured with data comparison information of table type, name, comparison code and in-table code forming corresponding relation.
In this embodiment, the encoding process specifically includes:
step S201, determining the format of ciphertext matched with plaintext to be transmitted in a ciphertext template, and determining the corresponding ciphertext code of the matched ciphertext template as the first field of the ciphertext;
step S202, sequentially determining text segments matched with names in a basic data table in a plaintext to be transmitted according to the sequence of the basic data table in the ciphertext template, and obtaining corresponding in-table codes;
step S203, determining a comparison code corresponding to the text segment according to the corresponding information of the in-table code of the text segment in the comparison table;
step S204, determining the comparison code as a field of the ciphertext;
step S205, setting separators among various fields of the ciphertext.
In one possible implementation, when the in-table code of the text segment does not exist in the comparison table, a difference value between the in-table code and the reference value is determined as a field of the ciphertext based on the reference value of the base data table in which the in-table code exists.
Further, the reduced encoding may take the following three ways:
1) The method is suitable for data (incremental data) with regularity, a preset value of basic table data is set, when the data is a default value, the data is empty, the data is directly decoded into the preset value after being received, and when the data value is not empty, the difference value between the data value and the preset value of the data is filled;
2) The data type classification is simplified, such as a time field, a time character string is converted into 4 bytes, fixed time is taken as an anchor point, and the time is converted into integer numbers in seconds.
3) The data comparison method is suitable for data values with unobvious rules, a comparison table is designed, and the corresponding data values are converted into 1-4 bytes (associated values).
And step S3, transmitting the ciphertext.
In this embodiment, the transmission process avoids transmission in a plaintext form, which improves security, and the transmitted ciphertext is subjected to the above-mentioned reduction processing, so that system performance and efficiency can be effectively improved.
And S4, after the transmission is completed, decoding the ciphertext by using the configured template data.
In this embodiment, the decoding process specifically includes:
step S401, removing the separator of the ciphertext;
step S402, determining a corresponding ciphertext template according to the first field of the ciphertext;
step S403, according to the sequence of each basic data table in the ciphertext template, determining the basic data table corresponding to each field except the first field in the ciphertext;
step S404, inquiring the corresponding plaintext in the basic data table according to the numerical value represented by each field in the plaintext.
That is, the reduced data is first decomposed according to the separator, then the corresponding template is searched through the data template table according to the first value, and then the corresponding basic table is searched according to the data item in the template, so that the plaintext information is resolved. The reduced decoding is a reverse operation of reduced encoding, comprising:
1) And when receiving the reduced data, acquiring a preset value through a corresponding basic table, adding the preset value to the reduced data to obtain an internal code value of the basic table, and inquiring a corresponding name through the internal code value to obtain a plaintext name.
2) And (3) reverse data type classification decoding, namely, taking the fixed time as an anchor point for receiving a time field, and converting the obtained integer number into a time format of YYYY-MM-DD hh: MM: ss format.
3) The reverse data comparison method is used for receiving the simplified data, inquiring the real internal code through the table type and the comparison value of the comparison table, and inquiring the name corresponding to the basic data table according to the real internal code, namely the name of the plaintext.
Compared with the prior art, the embodiment has at least the following advantages:
1) The size of transmission data is greatly reduced through simplifying the ciphertext;
2) And a ciphertext transmission mode is adopted, so that plaintext data transmission is avoided, and the safety is improved.
