A kind of block chain private key recovery mnemonic word System Design, it is related to block chain Floor layer Technology field.It is comprised the steps of：A, the character string of block chain account private key is generated into multiple Chinese mnemonic words at random, and using the spread pattern of multiple lines and multiple rows；B, user inputs self-defined mnemonic word；C, the character string of the mnemonic word and block chain account private key of the multiple Chinese mnemonic words and User Defined input that generate at random is uniquely mapped；The Chinese mnemonic word and self-defined mnemonic word that user while submission generate at random are needed when d, giving block chain account private key cryptographic for change.After adopting the above technical scheme, the present invention has the beneficial effect that：It uses main mnemonic word of the Chinese mnemonic word as block chain private key, effective memory of Chinese user can be facilitated, the pattern being combined with Chinese mnemonic word using User Defined mnemonic word, effective memory that Chinese uses crowd can be greatly improved, and the better securely held private key of energy, improve the safety of block chain account.
Description
Technical field
The present invention relates to block chain Floor layer Technology fields, and in particular to a kind of block chain private key restores mnemonic word system and sets
Meter.
Background technology
Block chain is the novel of the computer technologies such as Distributed Storage, point-to-point transmission, common recognition mechanism, Encryption Algorithm
Application model.So-called common recognition mechanism is that the mathematics calculation for trusting, obtaining equity is established between realizing different nodes in block catenary system
Method.Block chain is a key concept of bit coin, it is substantially the database of a decentralization, while as bit coin
Floor layer Technology.Block chain is a string of data blocks using the associated generation of cryptography method, is contained in each data block
The information of bit coin network trading, the validity for verifying its information and the next block of generation.
Mnemonic word is another form of expression of private key in block chain, and mnemonic word has function same with private key, leading
When entering wallet, as soon as it inputs mnemonic word and resets a password, wallet can be entered and possess the control power of this wallet, and can
The token in wallet is moved away.If once having revealed your mnemonic word, that is equal to run nakedly, therefore mnemonic word is important
Property is very high.
Existing bit coin private key can carry out private key backup by English mnemonic word, can pass through English when private key is lost
Literary mnemonic word carries out private key and gives for change.English mnemonic word and Chinese mnemonic word are defined in bit coin agreement Bip-0039.In but
The function of the mnemonic word assisted memory of text is good not as good as the effect of English mnemonic word.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of block chain private keys to restore mnemonic word
System Design, it can solve existing block chain mnemonic word using the assisted memory function of Chinese mnemonic word not as good as English mnemonic word
The good defect of effect.
To achieve the above object, the present invention is using following technical scheme：It is comprised the steps of：
A, the character string of block chain account private key is generated into multiple Chinese mnemonic words at random, and using the arrangement of multiple lines and multiple rows
Form；
B, user inputs self-defined mnemonic word；
C, by the mnemonic word and block chain account private key of the multiple Chinese mnemonic words and User Defined input that generate at random
Character string uniquely map；
The Chinese mnemonic word and make by oneself that user while submission generate at random are needed when d, giving block chain account private key cryptographic for change
Adopted mnemonic word.
Further, in the step a generation of block chain account private key need according to the random number of a 128bit and
It is carried out the number for being cut into 12 groups of 11bit by the number of the 132bit of the check digit composition of 4bit by 11bit for unit,
The number of each group of 11bit corresponds 2048 all between decimal system 0-2047, by 2048 numbers between 0-2047
A Chinese vocabulary generates multiple Chinese mnemonic words at random to be searched.
Further, Chinese mnemonic word is Chinese word in the step a.
Further, the spread pattern that multiple Chinese mnemonic words arrange for four rows three in the step a.
Further, self-defined mnemonic word is Chinese mnemonic word or English mnemonic word in the step b.
After adopting the above technical scheme, the present invention has the beneficial effect that：It is using Chinese mnemonic word as block chain private key
Main mnemonic word can facilitate effective memory of Chinese user, while using User Defined mnemonic word and Chinese mnemonic word phase
In conjunction with pattern, can greatly improve Chinese use crowd effective memory, and can preferably securely held private key, improve block
The safety of chain account.
Specific implementation mode
Present embodiment the technical solution adopted is that：It is comprised the steps of：
A, the character string of block chain account private key is generated into multiple Chinese mnemonic words at random, multiple Chinese mnemonic words are 2048
A middle word is optionally combined arrangement and generates, and Chinese mnemonic word is the random combine of Chinese word, the multiple Chinese mnemonic(al)s generated at random
Word uses the spread pattern of multiple lines and multiple rows, the spread pattern of preferably four rows three row；
B, user can carry out the defeated of self-defined mnemonic word after inputting block chain account password by client interactive interface
Enter, the form of word, Chinese word, English word is as self-defined mnemonic word during self-defined mnemonic word can input；
C, by User Defined inputs in the multiple Chinese mnemonic words and step b that are generated at random in step a mnemonic word with
The character string of block chain account private key is uniquely mapped, and block chain account private key is helped by Chinese mnemonic word and User Defined
The form of note word is backed up；
User is needed when d, giving block chain account private key cryptographic for change while submitting the Chinese mnemonic word generated at random in step a
With user-defined mnemonic word in step b.
Having 2048 Chinese words, these Chinese words in the dictionary of design is generated by 11bit；Stochastic production mnemonic word is adopted
With following process：
1, Chinese mnemonic word random number length can 128,160,256 correspond to 12,16,24 words, word respectively
Number is n/11, and 128 aliquant 11 so want cover, 32+1/11 just aliquots, so the corresponding mnemonic word number of length
Amount is (128+128/32)/11=12, and 128/32 is verification bit length.
2, SHA256 is unidirectional irreversible certainty HASH, generates the number that content is 256, foremost 128/32bit is taken to make
For check bit, similarly the corresponding increase length of 160,256 random seeds is 5,8.
3, random number and check bit are combined and generate a new word bit array.
4, divide 132/11=12 mnemonic word by 11 etc. the byte arrays of 128+4, similarly (160+5)/11=16 are helped
Remember word.
5, the corresponding index of the character of every 11 bit takes 2048 mnemonic word dictionary enquirings, because 2 11 powers are just
2048。
6, mnemonic word is generated according to corresponding dictionary word.
7, identical probability is 12 mnemonic words at random：1000*1000*10001000*1000*10001000*1000*
1,000,000,000 * of 1000*1000*1000*1000*1000*4=10 hundred million *, 1,000,000,000 *, 1,000,000,000 * 1000*4 Fen ー, probability is very low, substantially
It is difficult to repeat, it is safe.
The memory that Chinese uses crowd is substantially increased by Chinese mnemonic word, the self-defined mnemonic word word of extension can pacify
All risk insurance deposits private key, improves the safety of block chain account.
The above is merely illustrative of the technical solution of the present invention and unrestricted, and those of ordinary skill in the art are to this hair
The other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention,
It is intended to be within the scope of the claims of the invention.
