Description
Technical Field
The invention discloses a computer data compression and encryption technology, and particularly relates to a network data coding and encryption algorithm thereof.
Background
Data compression technology, that is, technology for representing signals by using minimum numbers; the basic process of the encryption algorithm is to process the original plaintext file or data according to a certain algorithm to make the original plaintext file or data become an unreadable segment of code, which is generally called as "ciphertext", so that the original content can be displayed only after a corresponding key is input, and the purpose of protecting the data from being stolen and read by an illegal person is achieved through the way. Current data compression and encryption algorithms are well-established, but have a number of problems, such as: most of the current algorithms are complex in calculation and have high requirements on the performance of hardware; the data volume increases after encryption; currently, the compression algorithm and the encryption algorithm are independent, so that the operation cost is increased, and based on the problems, the existing compression and encryption algorithms are difficult to operate on a low-end processor or operate at high efficiency, so that the response capability of the embedded component is greatly influenced.
In addition, the technical scheme in the current market pursues multiple application scenes and multi-language access, so that the corresponding algorithm is increasingly bloated and the calculation is increasingly complex, the format of the current data is mostly sent by JSON, XM L and other protocols, the content is sent in a Key-Value form, the readability is enhanced, but the data size and the complexity of a processing program are greatly increased.
Therefore, in view of the defects of the prior art, those skilled in the art are devoted to developing a network data encoding and its encryption algorithm to achieve simultaneous data compression and encryption, and reduce the amount of transmitted data, so that the network data encoding and its encryption algorithm can be applied to high-end processor devices and low-end processor devices.

step 2: during transmission, compressing original data to be transmitted, and reserving effective data in the transmitted data;
step 3: mapping the effective data in Step2 to the private coding table created in Step1, and partitioning the effective data through the partition codes of the private coding table;
step 4: the data receiving end receives the data re-encoded in Step3, decodes the data, and re-maps the data to the original data.
Further, in Step1, a private code sheet was created using the same eight bit bits to express 128 characters, with reference to the standard ASC LL (american standard code for information exchange, a computer code system based on latin letters, mainly used to display modern english and other western european languages, being the most common standard for information exchange, and being equivalent to the international standard ISO/IEC 646).
Further, in the private coding table, the last seven bits (bit 1-7 bits) of the eight bits represent data characters, and the first bit (bit0 bit) divides the code to express the continuity of the data.
Furthermore, the number and the types of the characters of the private coding table are the same as those of the ASC LL table of the original data referred by the private coding table, and in order to increase the difficulty of data cracking, the same set of corresponding tables of the scrambled characters and the indexes are used for encrypting the communication data at the data sending end and the data receiving end of program communication.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A network data coding and encrypting method at least comprises the following steps:
step 1: a data sending end creates a private coding table and determines data bits and segmentation codes of the coding table;
step 2: during transmission, compressing original data to be transmitted, and reserving effective data in the transmitted data;
step 3: mapping the effective data in Step2 to the private coding table created in Step1, and partitioning the effective data through the partition codes of the private coding table;
step 4: the data receiving end receives the data re-encoded in Step3, decodes the data, and re-maps the data to the original data.
Based on the above steps, the following examples are used for specific explanation.
Fig. 1 is a current general standard ASC LL table, and the general standard ASC LL table expresses 128 characters by eight bits, wherein, the first 7 bits (bit0-6 bits) express data, and the last bit (bit 7 bits) is used as parity bits, in this embodiment, the technical solution of the present embodiment is adjusted by taking the standard ASC LL table in fig. 1 as reference, the last seven bits (bit 1-7 bits) express ASC LL characters, and the first bit (bit0 bit) partition code expresses data continuity, as shown in fig. 2.
The number and type of characters of the new private coding table are the same as those of ASC LL of original data referred by the new private coding table, so as to increase the difficulty of data cracking, the same set of corresponding tables of scrambled characters and indexes are used at the data sending end and the data receiving end of program communication to encrypt communication data.
As shown in fig. 3, when the format of the current data is mostly sent in the JSON, XM L, etc., the content is sent in the form of Key-Value, in the data transmission, because both ends of the communication protocol are defined, the "Key" data in the data belongs to the data known by both ends of the communication protocol, and there is no need to repeat the transmission, and the "Value" data unknown by both ends of the communication protocol is encoded as the effective data for data transmission.
As shown in fig. 4, the Byte (Byte, a unit of measurement used in computer information technology to measure storage capacity, and 1Byte ═ 8bit) of the same data is represented by the same data, and the Byte of the next data is the inverse of the previous data.
And the data receiving end decodes the recoded data after receiving the recoded data and remaps the recoded data into original data.
In order to enable the private code table in the present technical solution to be efficiently applied to the current mature technical framework, the private code table in the present technical solution is designed to be compatible with the ASC LL code table, that is, the data in the ASC LL table of the original data is shifted to the new private code table by one bit to the left, such as:
byte date＝0b01010101；
date＝date<<1；
transcoding can be done for 32 bits of data by:
byte[]bs＝new byte[4]；
byte a＝(byte)(number>>24)；
byte b＝(byte)((number&0xff0000)>>16)；
byte c＝(byte)((number&0xff00)>>8)；
byte d＝(byte)(number&0xff)；
bs[0]＝a；bs[1]＝b；bs[2]＝c；bs[3]＝d；
for(int i in bs)
{
Bs[i]＝Bs[i]<<1；
