Description
Technical Field
The application relates to the technical field of block chains, in particular to a symbol mnemonic word generating method, a symbol mnemonic word converting device and electronic equipment.
Background
Blockchain techniques are based on decentralization and achieve trust through different participant interactions; ownership of its account is determined by a digital key, bitcoin address and digital signature. The digital key is not actually stored in the network but is instead stored in a file called a wallet or simply a database after being generated by the user. The digital key stored in the user's wallet is completely independent of the bitcoin protocol and can be generated and managed by the user's wallet software without reference to the blockchain or access to the network. The key enables many interesting features of bitcoin, including decentralized trust and control ownership authentication and a cryptographically proof-based security model.
The block chain wallet generating method includes generating mnemonic words, generating a private key of a deterministic wallet according to the mnemonic words, generating a public key by the private key, and generating a wallet address by the public key. Once the mnemonic is determined, control is given over the generated wallet. When a wallet is created, mnemonics are required to be recorded; when the wallet needs to be recovered according to the mnemonic words, the mnemonic words need to be input through a keyboard.
The corresponding mnemonic words of the wallets with different security levels are different in number, and the number of the mnemonic words is as much as 24 in some wallets, so that the recording and inputting operation is quite inconvenient. Therefore, in the whole wallet creating or recovering process, the convenience of mnemonic word recording or mnemonic word input plays a very important role in the user experience.
At present, in the BIP (Bitcoin Improvement suggestions) 39 standard, conventional mnemonics are all implemented by 2048 english words, which is advantageous for being used on blockchain wallet devices or APPs (applications) of different manufacturers. However, the conventional mnemonics are realized by English words, users need to input letters of each mnemonic one by one, and many users are often unfamiliar with the words, so that the user input is easy to be mistaken.
Disclosure of Invention
An object of the embodiments of the present application is to provide a symbol mnemonic word generating method, a symbol mnemonic word converting device, and an electronic device, so as to solve the problem that the conventional mnemonic word input is complicated and the user input is easy to be mistaken.

In the implementation process, the index sequence number of the mnemonic word is converted into a binary number of a preset binary system, and the binary number is used as a symbol mnemonic word and is distributed to the user. Therefore, the user needs to memorize the number elements of the common system number, and then only needs to input the corresponding common number elements when using the mnemonic word, compared with the traditional mnemonic word, the user has higher familiarity with the number elements and is easier to memorize, and the user is less prone to mistake input.
Further, the number of characters in the symbol mnemonic word is n; the nth power of the number of elements in the preset system number is more than or equal to the maximum number of the mnemonic words represented by the mnemonic word index sequence number.
In the implementation process, the symbol mnemonic word always has n characters, so that the user only needs to memorize the symbol mnemonic word according to the n characters when memorizing, and the user can memorize the symbol mnemonic word conveniently. Meanwhile, when the user uses the symbol mnemonic words in the later period, the system can also realize the preliminary verification of the symbol mnemonic words input by the user based on the number of the characters of the symbol mnemonic words, and eliminate the condition of obvious input errors, thereby solving the problems of different numbers of the characters of the existing mnemonic words and difficult memory.
Further, the preset scale is a 13 scale.
In the BIP39 standard, conventional mnemonics are implemented using 2048 unified english words. And 3-bit 13-ary number can represent 2197 numbers between 0 and 2196, so that the index sequence numbers of 2048 mnemonics in BIP39 can be completely covered without leaving too many invalid values. Meanwhile, the 13-system number can represent the index sequence number of the corresponding mnemonic word only by 3 characters at most, and the memory of a user is facilitated.
The embodiment of the application also provides a mnemonic word conversion method, which comprises the following steps: receiving an externally input symbol mnemonic word; the symbol mnemonic words are binary numbers of a preset binary system; converting the symbol mnemonic words into mnemonic word index serial numbers; and looking up a table to obtain a corresponding mnemonic word according to the mnemonic word index serial number.
In the implementation process, the symbol mnemonic words can be converted back to the corresponding mnemonic word index serial numbers, and then the corresponding mnemonic word (namely the traditional mnemonic word) is obtained based on a table look-up method, so that the symbol mnemonic word is convenient for a user to use in other traditional equipment.
Further, when receiving an externally input symbol mnemonic word, the method further comprises: checking whether the input symbol mnemonic word is in a preset legal range; and when the symbol mnemonic word is not in a preset legal range, prompting that the symbol mnemonic word is illegal.
In the implementation process, the value range of the symbol mnemonic words is checked, so that the symbol mnemonic words which are obviously not obtained by converting the index sequence numbers of the mnemonic words can be quickly eliminated, the modification by a user is facilitated, and the input reliability of the symbol mnemonic words is improved.
Further, the number of characters in the corresponding mnemonic word is n; the nth power of the number of elements in the preset system number is more than or equal to the maximum number of the mnemonic words represented by the mnemonic word index sequence number.
In the implementation process, the symbol mnemonic word always has n characters, so that the user only needs to memorize the symbol mnemonic word according to the n characters when memorizing, and the user can memorize the symbol mnemonic word conveniently. Meanwhile, when the user uses the symbol mnemonic words in the later period, the system can also realize the preliminary verification of the symbol mnemonic words input by the user based on the number of the characters of the symbol mnemonic words, and eliminate the condition of obvious input errors, thereby solving the problems of different numbers of the characters of the existing mnemonic words and difficult memory.
Further, when receiving an externally input symbol mnemonic word, the method further comprises: checking whether the number of characters in the input symbol mnemonic words is n; and when the number of the characters in the symbol mnemonic word is not n, prompting that the symbol mnemonic word is illegal.
In the implementation process, because the number of the characters in the symbol mnemonic words is fixed, the initial verification of the symbol mnemonic words input by the user can be realized based on the number of the characters in the symbol mnemonic words, and the condition of obvious input errors is eliminated, so that the input experience of the user is improved.
Further, the preset scale is a 13 scale, and n is 3.
The embodiment of the application also provides a wallet recovery or backup method, which comprises the following steps: receiving an externally input symbol mnemonic word; the symbol mnemonic words are binary numbers of a preset binary system; converting the symbol mnemonic words into mnemonic word index serial numbers; looking up a table to obtain a corresponding mnemonic word according to the mnemonic word index serial number; and generating a wallet secret key according to the mnemonic word.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The first embodiment is as follows:
referring to fig. 1, an embodiment of the present application provides a method for generating a symbol mnemonic word, including:
s101: and when a wallet creating instruction is received, acquiring a mnemonic word index sequence number.
It should be understood that, in the existing related protocol, the conventional mnemonic words are predefined, and each mnemonic word is assigned with a corresponding mnemonic index number. In general, during wallet generation, the device or system will derive the mnemonic index sequence number from the randomly generated entropy.
It should be understood that the mnemonic words are assigned to the user when the wallet is created, and the user can use the mnemonic words to perform wallet restoration or backup and other operations later, and the mnemonic words are not assigned to the user again.
S102: and converting the index sequence number of the mnemonic word into a preset system number.
S103: the system number is distributed to the user as a symbol mnemonic.
In the embodiment of the application, in order to facilitate the memory of the user, the number of characters in the system number corresponding to the maximum index number in the index numbers of the mnemonic words should not be too large, so as to prevent the user from difficultly memorizing.
For this reason, in the embodiment of the present application, a carry number of 5 or more and 5 or more may be selected for implementation. Taking the BIP39 standard as an example, as shown in fig. 2, 2048 english words in the BIP39 standard have mnemonic word index numbers ranging from 0 to 2047 (for convenience of description, the mnemonic word index numbers are described in 10-ary system, but in the actual application process, the corresponding relationship between 11-bit binary numbers and each mnemonic word is recorded in the device, and fig. 2 is a binary number), so that 2048 mnemonic word index numbers can be completely covered by 5-bit 5-ary numbers.
For example, in the embodiment of the present application, the preset-carry number may be set to be a 13-carry number. Because the 3-bit 13-system number can represent the 2197 number, the adoption of the 13-system number only needs 3 characters at most to completely cover 2048 mnemonic word index serial numbers, and because one symbol mnemonic word only needs 3 characters at most by a user, the mnemonic word is convenient for the user to memorize.
It should be noted that, in the embodiment of the present application, in order to facilitate the user to memorize and to perform input verification when the user uses the symbol mnemonic word later, the number of characters in the converted binary number (i.e., the symbol mnemonic word) may be set to be n.
It should be noted that the value of n should be greater than or equal to the number of characters required when the preset number of the system number represents the largest index number of the mnemonic word. That is, the nth power of the number of elements in the preset system is greater than or equal to the maximum number of the mnemonic words represented by the index sequence numbers of the mnemonic words. Taking 13-ary number as an example, if the BIP39 standard is adopted, since there are 13 digits in 13-ary, n should be greater than or equal to 3.
Generally, for the convenience of memory of the user, the value of n is equal to the number of characters required when the maximum index number of the mnemonic word is represented by the preset number. For example, when the preset number is a 5-ary number or a 6-ary number, the value of n may be 5; when the preset system number is a 7 system number to a 12 system number, the value of n can be 4; when the preset number is a 13-ary number to an 18-ary number, the value of n may be 3.
It should be noted that the number element is the most basic element constituting the binary number. For example, for binary numbers, 0 and 1 are binary digits. And 0 to 9 for decimal are the decimal number elements. And for the thirteen system, 0 to 9, a, b and c are the number elements of the thirteen system.
It should be noted that, for the number of the mnemonic index that can be expressed without n-bit binary numbers, the symbolic mnemonic can be made to have n characters by complementing 0. Exemplarily, taking a 13-ary number as an example, the 13-ary number has three elements, i.e., a, b, and c, in addition to 10 basic elements, i.e., 0 to 9, where a represents a number 10, b represents a number 11, and c represents a number 12; for the number 10 of the mnemonic word index, the corresponding 13-system number is a, and in order to make the symbol mnemonic word have 3 characters, 0 may be added before a to obtain a symbol mnemonic word 00 a.
It should be understood that, although the embodiment of the present application is described in terms of the BIP39 standard, in practical applications, the solutions provided in the embodiment of the present application may be used for other standards. For example, in the case of the menou coin, the number of mnemonics in the standard used is 1626, and the scheme proposed by the embodiment of the present application can also be used to provide the user with the generated symbolic mnemonics instead of the conventional mnemonic words.
It should be noted that, in the embodiment of the present application, in order to avoid a memory error of the user, when the system number is assigned to the user as a symbol mnemonic word, a confirmation key may be provided for the user to select and confirm whether the memory is completed.
In addition, in order to ensure that the memory of the user is correct, a symbol mnemonic word input interface can be provided after the confirmation information sent by the user is received, so that the user can input the symbol mnemonic word. In the embodiment of the application, the system compares the symbol mnemonic words input by the user with the symbol mnemonic words allocated to the user before, and the user is considered to have memorized the symbol mnemonic words after the comparison result is that the symbol mnemonic words are consistent with the symbol mnemonic words; otherwise, the symbolic mnemonic word can be provided for the user to memorize.
It should be understood that, in order to improve the generality of the symbol mnemonic word in the embodiment of the present application, an embodiment of the present application further provides a mnemonic word conversion method, which is shown in fig. 3 and includes:
s301: an externally input symbol mnemonic word is received.
In the embodiments of the present application, a dedicated device or software may be provided for the mnemonic conversion. The user may enter the assigned symbolic mnemonic using the scheme of the present application on a provided device or software.
S302: and converting the symbol mnemonic words into mnemonic word index serial numbers.
Since the symbolic mnemonics provided in the embodiment of the present application are obtained after the binary number conversion of the preset binary system, the symbolic mnemonics can be converted into the mnemonic index sequence number by the corresponding binary system conversion rule.
S303: and looking up a table to obtain a corresponding mnemonic word according to the mnemonic word index serial number.
According to the corresponding relation between the mnemonic words and the index sequence numbers of the mnemonic words recorded in the equipment or the system. And looking up a table through the index sequence number of the mnemonic word to obtain the corresponding mnemonic word.
In the embodiment of the present application, after obtaining the mnemonic word, the mnemonic word may be displayed to the user or directly imported into the corresponding wallet restoring or backup device, so that in a device that does not support inputting the symbolic mnemonic word provided in the embodiment of the present application, the wallet restoring or backup device may also be implemented based on the symbolic mnemonic word provided in the embodiment of the present application.
In an embodiment of the present application, there is further provided a method for recovering or backing up a wallet, as shown in fig. 4, including:
s401: an externally input symbol mnemonic word is received.
S402: converting the symbol mnemonic words into mnemonic word index serial numbers;
s403: looking up a table to obtain a corresponding mnemonic word according to the mnemonic word index serial number;
s404: and generating a wallet secret key according to the mnemonic word.
It should be understood that in the embodiment of the present application, the symbolic mnemonic word may be input through a keyboard having all the elements of the corresponding system number. Specifically, the apparatus or system may display a keyboard having digit input keys for a user to input a symbol mnemonic word through the digit input keys and receive the symbol mnemonic word input by the user through the digit input keys, before receiving an externally input symbol mnemonic word. The number input key is a key for inputting a certain character. For example, for a 10-system number, the keys corresponding to the numbers 0 to 9 are the number input keys. Meanwhile, the keyboard can be provided with some functional keys, such as a determination key, a cancel key and the like, besides the number element input key.
And in order to ensure the reliability and the effectiveness of input, the keyboard can be set to be matched with the corresponding carry number.
Illustratively, referring to fig. 5, taking 13-ary as an example, the number input keys of the keyboard are composed of ten number keys from 0 to 9 and three symbol number keys (three keys corresponding to characters a, b, c) for representing numbers 10, 11 and 12. In addition to the 13-digit input keys, the drawing may also have a confirm key "OK" and a Cancel key "Cancel".
It should be understood that, in addition to using the corresponding virtual keyboard, the embodiment of the present application may also be implemented by setting or connecting a corresponding physical keyboard on the device.
In the embodiment of the application, after the input symbol mnemonic word is received, whether the input symbol mnemonic word is in the preset legal range or not can be checked, and when the symbol mnemonic word is not in the preset legal range, the symbol mnemonic word is prompted to be illegal. For example, for the BIP39 standard, the preset legal range is 0 to 2047, and if the input symbolic mnemonic word is greater than 2047, it is obvious that the input symbolic mnemonic word is wrong, and the user may be prompted that the symbolic mnemonic word is illegal to re-input.
In addition, if the generated symbol mnemonic word is set to have n characters, in the embodiment of the application, whether the number of the characters in the input symbol mnemonic word is n or not can be checked, so that when the number of the characters in the symbol mnemonic word is not n, the symbol mnemonic word is prompted to be illegal. For example, for a 13-system number symbol mnemonic word, the set n is 3, and if the number of characters of the symbol mnemonic word input by the user is not n, it is obvious that the input symbol mnemonic word is wrong, and the user can be prompted that the symbol mnemonic word is illegal to input again.
In the method for generating the symbol mnemonic words provided in the embodiment of the application, the index serial numbers of the mnemonic words are converted into the binary numbers of the preset binary system, and the binary numbers are further used as the symbol mnemonic words to be distributed to users. Therefore, the user needs to memorize the number elements of the common system number, and then only needs to input the corresponding common number elements when using the mnemonic word, compared with the traditional mnemonic word, the user has higher familiarity with the number elements and is easier to memorize, and the user is less prone to mistake input.
Meanwhile, the mnemonic word conversion method provided by the embodiment of the application can convert the symbol mnemonic words back to the corresponding index serial numbers of the mnemonic words, and further obtain the corresponding mnemonic words based on a table look-up method, so that the method is convenient for users to use in other traditional equipment, and the scheme of the application has universality.
In addition, by the wallet recovery or backup method provided by the embodiment of the application, recovery or backup of the wallet based on the symbolic mnemonic words can be effectively realized. And because the user inputs simple symbol mnemonic words, compared with the driving mnemonic words, the input is simpler and more convenient.
Example two:
the present embodiment is based on the first embodiment, and the scheme of the present application is illustrated by a generation process of a specific 13-ary symbolic mnemonic word matching the BIP39 standard, and a recovery or wallet backup process of the 13-ary symbolic mnemonic word.
The generation process of the symbol mnemonic words comprises the following steps:
firstly, after the device receives a creation instruction of a user for a wallet, entropy is generated, the generated entropy is processed to obtain a binary sequence, each 11 bits of the binary sequence are used as a part, and each part corresponds to a mnemonic word (namely, each 11-bit binary sequence can be used as an mnemonic word index sequence number).
In the embodiment of the present application, each 11-bit binary sequence in the previous step may be converted into a mnemonic index number in 10, so as to perform conversion of a 13-system number.
Then, the index serial number of the mnemonic word in the 10-system scale is recorded as M, the index serial number of the mnemonic word is divided by 169 at first, the quotient is recorded as N, the remainder is O, and N is the highest bit of the symbol mnemonic word; then dividing O by 13 to be marked as P, and then P is the middle bit of the symbol mnemonic word; the remainder of dividing O by 13 is denoted as Q, which is the lowest bit of the signed mnemonic.
The correspondence between the 13-ary number symbol mnemonic word and the 10-ary mnemonic word index number can be seen in fig. 6.
And finally, displaying the obtained symbol mnemonic words to a user for recording.
The symbolic mnemonic displayed to the user is a 3-digit 13-system number. The user can basically judge whether the recorded symbol mnemonic words are correct or not according to the digits of the recorded symbol mnemonic words.
Wallet recovery or backup process:
a keyboard is provided as shown in fig. 5, in which a user can enter symbolic mnemonics.
When the user inputs a symbol mnemonic word, the user can click an OK key to indicate that the input of the symbol mnemonic word is finished. Meanwhile, if the symbol mnemonic word is input incorrectly, the user can click the "Cancel" key to input again.
And converting the symbolic mnemonic words into 10-system mnemonic word index serial numbers.
The process of converting to obtain the sequence number of the mnemonic index may be the reverse process of the foregoing process. The most significant bit N of the symbol mnemonic word may be multiplied by the square of the number of the system, the middle bit P of the symbol mnemonic word may be multiplied by the selected system, and the least significant bit Q of the symbol mnemonic word may be multiplied by the selected system, and added in sequence to obtain the mnemonic word index sequence M.
It should be noted that after the user inputs the symbol mnemonic word, the device may detect whether the symbol mnemonic word input by the user is converted into a decimal value greater than 2047, and if so, it is obvious that the user has input an error, and the user may be prompted to re-input.
In addition, after the user inputs the symbol mnemonic words, the device can detect the number of characters of the symbol mnemonic words input by the user, and if the number of the input characters is not 3, the user can be prompted to input errors and input again.
After the mnemonic word index sequence is obtained through conversion, the mnemonic word can be obtained through table lookup, and then the corresponding private key and the public key are generated according to the mnemonic word, so that the recovery or backup of the wallet is realized.
It should be noted that, in the conventional mnemonic words (i.e. mnemonic words), the keyboard provided by the system needs 26 number input keys, so each key is relatively small, and the user is inconvenient to input and is easy to input by mistake. Even if some systems are provided with an alphabet retrieval function, the rest of the alphabets can be automatically retrieved according to the alphabets input by a user, useless alphabet input is prevented, the alphabet input accuracy is improved, but the problems of consumption of computing resources and low keyboard response speed exist, and the sizes of keys are small. When the keyboard and the symbol mnemonic words provided by the embodiment of the application are adopted, under the same keyboard size, a single key is larger, and the user can input more easily. And meanwhile, retrieval and waiting are not needed. The advantages and disadvantages of using traditional mnemonics and using symbolic mnemonics are shown in the following table one:
The symbol mnemonic words in the embodiment of the application are considered from the aspects of research personnel and users, simple numbers and symbols are used for replacing the word form of the traditional mnemonic words, and the efficiency of recording the mnemonic words and inputting the mnemonic words is greatly improved no matter the user records the mnemonic words when a wallet is created or inputs the mnemonic words when the wallet is recovered, so that the user experience is improved. The 13-system symbol mnemonic words are simple, understandable and easy to convert, can be converted with the traditional mnemonic words at will, and can be used with wallet equipment of other manufacturers. Compared with the number of characters of a single symbol mnemonic word and the traditional mnemonic word, the symbol mnemonic words are all 3 characters, are relatively simple and unified, and are convenient to record and input, while the traditional mnemonic words are different in number of letters, and cannot be identified once the records are wrong or tampered by others.
