Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
the present application relates to a Block Chain technology, and for ease of understanding, a Block Chain (Block Chain) in the embodiment of the present invention will be briefly described below, and is a data structure of distributed storage disclosed for all Block Chain nodes of an access server, and includes several blocks (blocks). The user terminal containing the client can be registered as a block chain node, and forms a Peer-to-Peer network (Peer-to-Peer, P2P) with other block chain nodes accessed into the block chain server, block chain data can be stored in the P2P network, and any one or more block chain nodes of the P2P network are broken down, which can not cause the loss of the block chain data, so that the block chain data has strong security, and the permanent storage and the non-falsification of the data are ensured. In the block chain world, the account can be unlocked as long as the private key is reserved, but generally the private key is composed of a very long character string of 64 bits, if the user wants to create 100 accounts, 100 private keys are recorded, the recording and storage cost is very high, moreover, in the process of recording a large number of private keys, the problem that the address and the private key cannot be matched can also occur, or the problem that letters are wrongly written carelessly and carelessly during recording can also occur, and the probability of errors is very high, and in conclusion, due to the characteristic of 'only confirming the private key without a person' of digital currency, the assets cannot be found back due to small errors.
to solve the above problem, a Bip39 protocol (bitchoice protocol) has been proposed, which determines a user account by 12 mnemonics, and since the 12 mnemonics generate a large seed, a number is selected from the power of 256 of 2, and since the randomly generated number is large, there is no fear that the generated 12 mnemonics will be repeated. The process of generating the mnemonic words mainly comprises the following steps: first, a 128-bit random number is generated, and then a 4-bit check number for checking the random number is added to obtain a 132-bit number, then a segmentation is performed every 11 bits, so that 12 binary numbers are provided, and then each number is used to look up a word list defined by BIP39, so that 12 mnemonics are obtained. It is understood that in other embodiments of the present invention, when the number of the random numbers is different, the number of the mnemonic words may also be 15, 18, 21, or 24, which is set according to the actual use requirement, and is not limited herein.
The hardware wallet recovery method provided by the invention comprises the following steps: acquiring a plurality of dictionary codes sequentially input by a user, wherein the dictionary codes are unique codes of mnemonics in a dictionary; acquiring a plurality of corresponding mnemonics according to the dictionary codes; and restoring the hardware wallet according to the corresponding plurality of mnemonics. The method of the invention can realize the input of the mnemonic words by respectively corresponding all the mnemonic words with the dictionary codes and inputting the dictionary codes corresponding to the mnemonic words by the user when restoring the hardware wallet, so that the user only needs to input the dictionary codes corresponding to the mnemonic words on the existing input method keyboard, the hardware wallet can be restored according to a plurality of dictionary codes input by the user without inputting the mnemonic words, the problem that the existing keyboard can not input the mnemonic words of the required language is avoided, and the problem that the existing mnemonic words are inconvenient to input is solved.
In order to illustrate the technical solution of the present invention, the following is illustrated by specific examples:
example one
Fig. 1 is a flowchart illustrating a hardware wallet recovering method according to an embodiment of the present invention.
The hardware wallet recovery method provided by the embodiment of the invention comprises the following steps:
step S101, acquiring a plurality of dictionary codes sequentially input by a user;
The method is mainly applied to hardware wallets which are used for managing keys, addresses, tracking balance, creating transactions and the like. Wherein the hardware wallet may proceed to create a wallet private key and the new hardware wallet recovers the private key of the lost hardware wallet.
the main process of creating and generating the private key in the hardware wallet is as follows:
one, randomly generating a random number (entropy) of 128 to 258 bits;
Secondly, generating mnemonic words by the entropy through a certain processing method;
Thirdly, the mnemonic words pass through a key extension function PBKDF2 to generate seeds;
Fourthly, generating a mother key by the seed through an HMAC-SHA512 algorithm;
And fifthly, generating a plurality of sub keys by the parent key through a CKD (child key derivation) function.
in an embodiment of the present invention, a 128-bit random number is specifically generated, and at this time, a 4-bit check number for checking the random number is added to the 128-bit random number to obtain a 132-bit number, which is divided into 11 bits each to obtain 12 mnemonics, where it is to be noted that, in other embodiments of the present invention, the number of the mnemonics may also be any one of 15/18/21/24 by setting the number of the random numbers differently, and the number of the mnemonics may be set according to actual use requirements, which is not limited herein, and does not constitute a limitation to the present invention.
In this embodiment, 2048 mnemonics without grammar structure in a certain sequence are in one-to-one correspondence with dictionary codes through a preset rule, and a mnemonic dictionary in which the dictionary codes correspond to the mnemonics is determined.
when the hardware wallet is created, the hardware wallet randomly generates 12 mnemonics, generates a seed according to the 12 mnemonics, and further generates a sub private key subsequently. At this time, when the user recovers the hardware wallet, the user can recover the hardware wallet by inputting 12 mnemonics randomly generated at the time of creation in the hardware wallet.
Further, when the hardware wallet performs a recovery operation, the hardware wallet acquires a dictionary code input by a user through an input method keyboard, wherein the dictionary code is a unique code of a mnemonic word in the dictionary, and the dictionary code is mainly the number of the hardware wallet, for example, when the user inputs '1234' through the input method keyboard, the hardware wallet determines that the acquired dictionary code is '1234'.
Step S102, a plurality of corresponding mnemonic words are obtained according to the dictionary codes;
It should be noted that the mnemonics may be represented by a plurality of different languages, each language includes 2048 mnemonics corresponding to the language, and the existing languages include, but are not limited to, "simplified chinese," traditional chinese, "" english, "" french, "" japanese, "" korean, "" spanish, "and" italian.
the mnemonic word dictionary records the corresponding relation between each mnemonic word and the dictionary code thereof, and in the corresponding mnemonic words determined by the simplified Chinese through the preset rules, if the corresponding mnemonic word is 'one' when the dictionary serial number is '1', the corresponding mnemonic word is 'one' when the dictionary serial number is '2', and the corresponding mnemonic word is 'intermittent' when the dictionary serial number is '2048'. In each corresponding mnemonic word determined by the english through the preset rule, for example, the corresponding mnemonic word is "abandon" when the dictionary serial number is "1", the corresponding mnemonic word is "ability" when the dictionary serial number is "2", and the corresponding mnemonic word is "zoo" when the dictionary serial number is "2048".
at the moment, because the corresponding relation between each dictionary code and the mnemonic word is correspondingly formed through the preset rule, the mnemonic word required to be input by the user can be determined through dictionary inquiry of the mnemonic word according to the acquired dictionary code input by the user. Furthermore, when the user inputs the mnemonic words, the user needs to know the dictionary codes corresponding to the mnemonic words to be input in the mnemonic word dictionary in advance, and at the moment, the user can obtain and determine the corresponding mnemonic words by inputting the dictionary codes.
Step S103, restoring the hardware wallet according to the corresponding plurality of mnemonics;
in an embodiment of the present invention, the number of the mnemonics required to be generated is 12, so that the user sequentially inputs 12 dictionary codes, the hardware wallet acquires each mnemonic corresponding to each dictionary code according to each input dictionary code, and after acquiring the required number of mnemonics input by the user, the hardware wallet restores the hardware wallet according to each mnemonic, specifically, the hardware wallet generates seeds according to the acquired plurality of mnemonics and generates a sub-private key according to the seeds, so as to realize the restoration of the hardware wallet.
According to the hardware wallet recovery method provided by the embodiment of the invention, all the mnemonics are respectively corresponding to the dictionary codes, and when the hardware wallet is recovered, the entry of the mnemonics can be realized by inputting the dictionary codes corresponding to the mnemonics by a user, so that the user only needs to input the dictionary codes corresponding to the mnemonics on the existing input method keyboard, the recovery of the hardware wallet is realized according to a plurality of acquired dictionary codes input by the user without inputting the mnemonics, the problem that the existing keyboard cannot input the mnemonics of a required language is avoided, and the problem that the existing mnemonics are inconvenient to input is solved.
example two
Fig. 2 is a flowchart of a hardware wallet recovering method according to a preferred embodiment of the present invention.
the hardware wallet recovery method provided by the embodiment of the invention comprises the following steps:
step S201, sequentially acquiring numbers input by a user;
the hardware wallet inputs the mnemonic words through the input method keyboard, and at the moment, the hardware wallet can acquire keyboard numbers input by a user, for example, the user needs to input Chinese mnemonic word 'yarn', but the user cannot input the mnemonic words due to the limitation of the input method keyboard, at the moment, the user can search dictionary codes corresponding to the mnemonic words, the dictionary codes are determined to be '1234', at the moment, the user can sequentially press numbers '1', '2', '3' and '4' on the keyboard, and at the moment, the hardware wallet can acquire the numbers input by the user sequentially.
wherein, it should be noted that, before sequentially acquiring the numbers input by the user, it further includes:
acquiring a language code input by a user;
Determining the type of the mnemonic word language according to the language code;
and determining the mnemonic words corresponding to the dictionary codes according to the language type of the mnemonic words.
The user can select the type of the mnemonic word language generated by the required input, and corresponding mnemonic words and corresponding dictionary codes are obtained according to the type of the mnemonic word language selected by the user. For example, in this embodiment, the language includes "simplified chinese", "traditional chinese", "english", "french", "japanese", "korean", "spanish", and "italian", and each language also corresponds to a language code, for example, the language code corresponding to "simplified chinese" is "1", and the language code corresponding to "italian" is "8", at this time, the hardware wallet needs to confirm the language that the user needs to input before the user inputs the dictionary code corresponding to the mnemonic word, when the user inputs the language code "1" according to the prompt of the hardware wallet, the hardware wallet prompts the user whether to input the mnemonic word in "simplified chinese" corresponding to the language code "1", when the user presses the confirmation key, the dictionary code corresponding to the mnemonic word type that the user inputs is determined at this time, and acquiring the mnemonic words corresponding to each dictionary code in the mnemonic word language type.
Step S202, determining the dictionary code according to the acquired plurality of numbers which are input in sequence;
In the embodiment of the present invention, the number of the digits required for inputting the dictionary code is specifically 4-digit number, and the dictionary code required for inputting the dictionary code by the user can be determined according to the four digits input by the user, for example, when four digits "1", "2", "3" and "4" are sequentially input by the user, the dictionary code required for inputting by the user can be determined as "1234".
It should be noted that, in other embodiments of the present invention, a user may further input numbers less than 4 digits and determine the dictionary code corresponding to each number through a confirmation instruction, for example, when the dictionary code that the user needs to input is "0123", the user may input "0", "1", "2", "3", and confirm through the confirmation key, at this time, the hardware wallet determines that the dictionary code is "0123" according to the number of the first preset digit input by the user, the user may further input "1", "2", "3", and confirm through the confirmation key, at this time, the hardware wallet determines that the dictionary code is "0123" according to the number less than 4 digits input by the user.
the step of determining the dictionary code according to the obtained plurality of sequentially input numbers has a plurality of implementation manners, and in this embodiment, the following two implementation manners are provided:
the first method is as follows: when a deleting instruction for the currently input number is acquired, deleting the currently input number;
and when a confirmation instruction for a plurality of numbers input in sequence is acquired, determining the dictionary code according to the acquired plurality of numbers.
the second method comprises the following steps: when a deleting instruction for the number of the target digit is acquired, deleting the number input by the target digit;
When the number input by the user is obtained again, adding the input number to the position of the target digit or the tail end position of the target digit;
and when a confirmation instruction for a plurality of numbers input in sequence is acquired, determining the dictionary code according to the acquired plurality of numbers.
in the first mode, when a user has an error in currently input digits, the user can press a clear key on a keyboard, at this time, when the hardware wallet acquires a deletion instruction of the digits, the hardware wallet deletes the currently input digits and continues to acquire the digits input by the user until the user sequentially inputs the digits with 4 digits, at this time, each digit is displayed on the hardware wallet, when the user confirms that each digit has no problem, the user can press a confirmation key on the hardware wallet, and at this time, the hardware wallet determines a dictionary code according to the acquired confirmation instruction.
in the second mode, when the user inputs a plurality of numbers and has numbers input by mistake, the user can move to the current wrong input position by the moving key, when the user moves to delete the numbers of the target digit on the target digit, the numbers of the target digit can be deleted at this time, for example, when the user inputs "1", "3" and "4" in sequence, the user can move to the "1" of the second digit and delete the numbers by the deleting key when finding that the input numbers of the second digit are input by mistake, wherein it needs to be pointed out that the user can input the needed input numbers again after deleting the numbers of the target digit, in the embodiment, the input numbers can be added to the position of the target digit, for example, after the user inputs the needed "2", the "2" is added to the second digit so as to determine that the input dictionary code is "1234", or the number it enters may also be added to the end positions entered in turn. The specific positions of the added numbers can be set according to the actual use requirements, and are not limited herein, and the added numbers do not limit the invention.
Furthermore, after the user inputs a plurality of numbers and determines the dictionary code according to the input numbers, the hardware wallet judges whether the dictionary code determined according to the numbers input in sequence exceeds a preset code range;
if the dictionary code determined according to the plurality of sequentially input digits exceeds the preset coding range, sending an error prompt, and modifying the dictionary code to prompt a user that the currently input dictionary code is incorrect; otherwise, determining the dictionary code according to the acquired multiple numbers input in sequence.
for example, the preset rule determines that 2048 Chinese mnemonics correspond to each dictionary code and the corresponding code is 0001-2048, and at this time, it needs to determine whether the dictionary code input by the user exceeds the range of 0001-2048, for example, when the user inputs "3456", the hardware wallet cannot determine the corresponding mnemonics according to the input dictionary code, and at this time, when it is determined that the dictionary code input by the user exceeds the preset code range, an error prompt is issued to prompt the user to input the correct dictionary code and modify the currently input dictionary code. Specifically, the dictionary code may be modified in a manner that each number exceeding the preset code range is deleted, so that the user re-inputs four digits to determine a new modified dictionary code; or each digit can be displayed to ensure that a user determines the digit required to be modified, and after the corresponding digit is modified correspondingly, when the dictionary code is determined not to exceed the preset coding range according to the four modified digits, a new dictionary code is determined according to the current modification. It should be noted that when the dictionary code determined according to the numbers input by the user exceeds the preset coding range, the dictionary code will send an error prompt and no longer receive new numbers input by the user, and at this time, when the dictionary code exceeding the preset coding range is modified by the user and does not exceed the preset coding range, the dictionary code newly input by the user can be continuously received and obtained, and the corresponding dictionary code is sequentially determined according to a plurality of subsequently input numbers.
step S203, acquiring each dictionary code in sequence;
in this embodiment, the required number of mnemonics is 12, so that the user needs to input 12 dictionary codes in sequence, and it can be understood that in other embodiments of the present invention, other mnemonics meeting the number of rules can be input, which is not limited herein, and at this time, the hardware wallet sequentially obtains each dictionary code input by the user.
step S204, a plurality of corresponding mnemonic words are obtained according to the dictionary codes;
the hardware wallet searches the mnemonic word corresponding to the dictionary code according to the dictionary code input by the user, for example, when the dictionary code input by the user is 1234, the hardware wallet searches the corresponding mnemonic word as yarn through the mnemonic dictionary, and at the moment, the hardware wallet obtains the corresponding mnemonic word as yarn according to the dictionary code input by the user.
When the dictionary code input by the user exceeds the range of the dictionary code set by the preset rule, an error prompt is sent to the user, so that the user can re-input the dictionary code corresponding to the mnemonic word according to the error prompt.
step S205, displaying a plurality of dictionary codes sequentially input by a user and corresponding mnemonics determined according to the dictionary codes;
It should be noted that, a display device may be further disposed on the hardware wallet for displaying information input by the user. At the moment, when a user inputs dictionary codes through an input method keyboard, a display device of the hardware wallet can display the numbers input by the user in real time, the dictionary codes determined according to a plurality of numbers input by the user and the corresponding mnemonics determined according to the dictionary codes, so that the user can determine whether the input dictionary codes and the determined mnemonics are correct or not according to displayed information.
when the user determines that the input mnemonic word is wrong, the method further includes a step of modifying the mnemonic word, wherein the method for modifying the mnemonic word includes multiple methods, and in the embodiment, the following three embodiments are specifically provided:
The first method is as follows: when a deleting instruction of the currently input mnemonic word is acquired, the currently input mnemonic word is deleted, and the dictionary code input by the user is acquired again to determine the currently input mnemonic word.
the second method comprises the following steps: when a deleting instruction of the mnemonic words of the target digit is obtained, deleting the mnemonic words input by the target digit;
and when the mnemonic words determined by the dictionary code input by the user are acquired, adding the input mnemonic words to the positions of the target digits or the sequentially input tail end positions.
the third method comprises the following steps: when a first modification instruction of a target mnemonic word is acquired, displaying each number corresponding to a dictionary code of the target mnemonic word;
When a second modification instruction for the target number is acquired, replacing the target number according to the acquired number input by the user;
when a confirmation instruction for a plurality of numbers is acquired, determining a modified dictionary code according to the acquired numbers, and acquiring a corresponding modified mnemonic word according to the modified dictionary code;
the target mnemonic words are mnemonic words located in the target digit, and the target digits are digits of the target modification position.
in the second mode, after the user deletes the mnemonic word with the target digit, the position where the mnemonic word input again is added can be set according to the actual use requirement, and the position is not limited herein, and does not form the limitation of the invention.
