Abstract
The invention discloses a kind of decoding method of invisible character data circulation character visible data flow, to realize in being spaced according to every 6 binary digits by the binary number of invisible character data stream, then two bits that value added is 01 before every 6 binary digits of the invisible character data flow data, enable every 8 binary digits to form a character visible.Decoded major way is then that the binary number for needing decoded character visible data flow is spaced into one group of data according to every 8 binary digits, then removes the first two character visible mark binary digit of every 8 binary digits.The advantageous effects of the present invention by the circulation of invisible character data by turning to character visible data flow, it can realize the transmission that invisible character data stream is carried out in the scene that can not transmit invisible character, increase the data transmission applications scene of invisible character with this.
Description
Technical field
The present invention relates to a kind of data decoding method, more particularly to a kind of invisible character data circulation character visible number
According to the decoding method of stream.
Background technology
In computer systems, all data will be identified in storage and computing using binary number, in order to unite
Binary number and coded identification can be made to carry out unification, related standardization body of the U.S. has just put into effect ASCII codings, unified two into
The mapping relations of number and character code processed.
In ASCII codings, 32-126 is that character visible is shown, remaining is generally reserved characters or invisible word
Symbol.In some specific equipment or network, invisible character is often transmitted as forbidden character without allowing, wherein often
See such as Big Dipper short message channel, its significant character collection for allowing to transmit includes all printable ascii characters（HEX20 is arrived
HEX7F）.
In general, when being compressed encryption to data, invisible character is often carried in data, then in specified conditions
Under, some encryption policies will be subject to equipment and network on after invisible character filtering can not normal transmission influenced so that
Cause the encryption policy or data can not use or transmit in the present context.
The content of the invention
The problem of according to background technology, invented a kind of invisible character data circulation character visible data flow herein
Decoding method, complete to transmit the binary data stream containing invisible character under given conditions with this.
The binary number of invisible character data stream is being spaced into one group of data according to every 6 bits, so
Two bits that value added is 01 before every 6 bits of the invisible character data flow data afterwards, make position bit of every eight bits
A character visible can be formed, flowed to so as to fulfill invisible character data character visible data flow code conversion it is main
Flow.Decoded major way is then that will need the binary number of decoded character visible data flow according to position bit of every eight bits
One group of data is spaced into, then removes the first two bit of position bit of every eight bits, so that new character data stream is formed,
Wherein can there are invisible character data.
The method have the benefit that：, can by the way that the circulation of invisible character data is turned to character visible data flow
To realize the transmission that invisible character data stream is carried out in the scene that can not transmit invisible character, invisible word is increased with this
The data transmission applications scene of symbol.
Brief description of the drawings
Attached drawing described herein is used for providing a further understanding of the present invention, forms the part of the application, this hair
Bright illustrated embodiment and its explanation is used to explain the present invention, does not form inappropriate limitation of the present invention.
Attached drawing 1, a kind of coding flow chart of the decoding method of invisible character data circulation character visible data flow；
Attached drawing 2, a kind of embodiment cataloged procedure figure of the decoding method of invisible character data circulation character visible data flow；
Attached drawing 3, a kind of embodiment decoding process figure of the decoding method of invisible character data circulation character visible data flow.
Embodiment
The ascii character scope of character visible is HEX20 to HEX7F, is when being encoded using 8 bits
00100000 to 01111111.Therefore can draw when the first two binary digit in a byte be 01 when, behind 6
After any value of binary digit, the byte is still in the range of HEX20 to HEX7F.
According to above-mentioned characteristic, the present invention devises a set of with reference to the code identification position that have selected using 01 as character visible
Make the decoding method of invisible character data circulation character visible data flow.
A kind of coding flow chart such as institute of attached drawing 1 of the decoding method of invisible character data circulation character visible data flow
Show.Invisible character data stream N is spaced apart according to every 6 binary digits for one group, in the binary digit of last packet
Before supply the bit that M is 0, until length of the group for 6 binary digits, the character data stream are grouped into N2；M is converted to
The binary number of 6 binary digits, and by the binary number be added to N2 packet after, form new invisible character data flow point
Group N3；By packet two binary digits that above value added is 01 of 6 bit intervals in N3, the data flow after coding is S,
Character in S is just all character visible.The decoding process of the present invention is the reverse flow of above-mentioned cataloged procedure, therefore the present invention does not make
It is explained further, with reference to above-mentioned flow inverted order.
A kind of embodiment cataloged procedure figure of the decoding method of invisible character data circulation character visible data flow is such as
Shown in attached drawing 2, original invisible character data stream encryption is：0000000100000001000000100000001100000100
, it is 00,000,001 00,000,001 00,000,010 00,000,011 00000100 according to 8 one group of data encoding, by original word
It is 000,000 010,000 000,100 000,010 000,000 110000 that data flow, which is accorded with, according to 6 one group of data encoding
0100, in this group of data, last group is simultaneously 6 inadequate.Therefore, end packet is handled, is mended before its binary digit
0, until it is 6, which is encoded to 000,000 010,000 000,100 000,010 000,000 110000000100, the binary digit that its underscore is identified is added value.Since increased binary digit needs to show number, to solve
The coding of addition can be released when code, therefore the present invention adds 6 packets after the binary data stream, is used for
The number of above-mentioned increase by 0 is identified, has mended two 0 according to embodiment, then new binary data stream is encoded to 000,000 010000
000100 000010 000000 110000 000100 000010.As a result restructuring sequence, after the packet transaction of end, then by 01
The front two of above-mentioned each packet binary digit is put in as character visible flag, new binary data stream is formed and compiles
Code be01000000 01010000 01000100 01000010 01000000 01110000 01000100 01000010,
The character visible flag that the string data increases newly is protruded with underscore and identified, this data is just the character visible data after coding
Stream.
A kind of embodiment decoding process figure of the decoding method of invisible character data circulation character visible data flow is such as
Shown in attached drawing 3, character visible data flow to be decoded is 01,000,000 01010000 according to 8 one group of data encoding
01000100 01,000,010 01,000,000 01,110,000 01,000,100 01000010, its character visible flag is removed,
Remove 01 bit before each byte, and be 000000 according to 6 one group of data encoding by the character data stream of letter
010000 000100 000010 000000 110000 000100 000010, in this group of data last group band under draw
The data of line are used for representing the number that second from the bottom group of data mend 0, therefore original data stream is 000,000 010,000 000100
000010 000,000 110,000 0100, it is ordered as 00,000,001 00,000,001 00000010 according to byte packet
00000011 00000100, that is, complete decoding process.
