Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
First, a method for generating a block chain ID according to an embodiment of the present invention is described below.
The block chain ID generation method provided by the embodiment of the invention can be applied to any electronic equipment in a block chain, such as a server, a computer, a mobile terminal and the like.
As shown in fig. 1, a method for generating a block chain ID according to an embodiment of the present invention may include:
s101: and receiving a blockchain ID creation request sent by a user, and generating a plurality of groups of public and private key pairs based on a preset hierarchical deterministic algorithm, wherein one group of public and private key pairs comprises a public key and a private key.
When a user wants to obtain a block chain ID of the user, a block chain ID creation request is sent, where the way for the user to send the block chain ID creation request may be: click on the blockchain ID creation button in the virtual wallet.
After receiving a blockchain ID creation request sent by a user, knowing that the user wants to create a blockchain ID, a plurality of sets of public and private key pairs may be generated based on a predetermined hierarchical deterministic algorithm, where a set of public and private key pairs includes a public key and a private key.
Referring to fig. 2, the generating a plurality of sets of public and private key pairs based on a predetermined hierarchical deterministic algorithm may include:
s1011: a random number is obtained.
In the predetermined hierarchical deterministic algorithm, a random number is used to generate the master private key, i.e. the root private key, which is not different from any private key generated by any bitcoin wallet.
In the embodiment of the invention, a preset random number generation algorithm can be adopted to generate the random number and obtain the random number.
S1012: a master private key is generated based on the random number.
After the random number is obtained, a master private key may be generated based on the random number, where the way of generating the master private key based on the random number may be: and generating a main private key based on the random number according to a BIP32 protocol, wherein the BIP is a Bitcin Improvement protocol.
S1013: and generating a plurality of groups of public and private key pairs based on the main private key and the plurality of generation paths, wherein different generation paths correspondingly generate different public and private key pairs.
After the master private key is generated, multiple sets of public and private key pairs may be generated according to multiple different generation paths, where each generation path generates a different public and private key pair, and the different generation paths may be determined based on currencies, for example, it may be set that each currency corresponds to one generation path.
For example: the bit currency corresponds to a bit currency public and private key generation path, and the ether house corresponds to an ether house public and private key generation path.
For example, the generating path may be determined by: according to the BIP44 protocol, a nonrepeating path is set for each currency, and the nonrepeating path is the generation path of the currency public and private keys.
Therefore, a plurality of groups of public and private key pairs are generated based on the preset layered deterministic algorithm.
S102: from the multiple sets of public and private key pairs, a target public and private key pair is selected.
Since the blockchain ID to be generated is the unique identifier of the user in the blockchain, there is only one blockchain ID for each user, and therefore, in order to generate the blockchain ID for the user, after generating a plurality of sets of public and private key pairs, it is necessary to select a target public and private key pair from the plurality of sets of public and private key pairs, that is, select a set of public and private key pairs from the plurality of sets of public and private key pairs.
In an implementation manner, a public and private key pair corresponding to a target generation path may be obtained from multiple sets of public and private key pairs as a target public and private key pair.
The target generation path may be a randomly selected generation path. The advantage of selecting the target public and private key pair is that the selected target public and private key pair has no regularity and is difficult to crack, and the safety of the target public and private key pair is ensured.
Alternatively, the target generation path may be one selected according to a preset rule.
Or, in another implementation, the target public-private key pair may also be directly selected from multiple sets of public-private key pairs, for example, a certain public-private key pair may be randomly selected, or a certain public-private key pair may be selected according to a preset rule.
S103: and encoding the public key in the target public and private key pair to generate the block chain ID of the user.
In order to generate the blockchain ID, after the target public and private key pair is selected, the public key in the target public and private key pair may be encoded to generate the user blockchain ID, and the private key in the target public and private key also corresponds to the generated blockchain ID, that is, the private key in the target public and private key may be used as the private key of the blockchain ID, and the two may be mutually verified. The encoding method for encoding the public key in the target public-private key pair may be any one, and is not limited herein.
In the embodiment of the invention, a block chain ID creation request sent by a user is received, a plurality of groups of public and private key pairs are generated based on a preset layered deterministic algorithm, wherein one group of public and private key pairs comprises a public key and a private key, a target public and private key pair is selected from the plurality of groups of public and private key pairs, and the public key in the target public and private key pair is encoded to generate the block chain ID of the user. In the invention, a plurality of groups of public and private key pairs are generated based on a preset layered deterministic algorithm, then a target public and private key pair is selected from the plurality of groups of public and private key pairs, and finally a block chain ID of a user is generated in a mode of coding a public key in the target public and private key pair, so that the block chain ID is used as an identifier of the user in a block chain to represent the user.
On the basis of the method shown in fig. 1, after step S103, referring to fig. 3, the method for generating a block chain ID according to the embodiment of the present invention may further include:
s106: and taking each public key in the remaining public and private key pairs except the target public and private key pair in the plurality of groups of public and private key pairs as the wallet address of the user.
Since a user may have multiple virtual wallets, each virtual wallet corresponds to a wallet address, and each user performs transactions based on the respective wallet addresses, in order to enable the user to correspond to a corresponding wallet address after the virtual wallet is created, public and private key pairs in multiple sets of public and private key pairs may be used, and each public key in the remaining public and private key pairs except the target public and private key pair is used as the wallet address of the user.
Of course, the public key in the target public-private key pair, i.e., the public key of the blockchain ID, may also be used as the user's wallet address.
S107: and establishing and storing the corresponding relation between the block chain ID and the wallet address.
Since each generated wallet address is owned by the same user, in order to facilitate management of virtual wallets and transfer of money, and in order to enable other users to know to which user each virtual wallet belongs, a correspondence between a block chain ID and a wallet address needs to be established, and after the correspondence between the block chain ID and the wallet address is established, the established correspondence needs to be stored.
Assuming that the blockchain ID of the user M is A, in the multiple groups of public and private key pairs, the public keys in the remaining public and private key pairs except the target public and private key pair are respectively: B. c and D, then: B. c and D as the wallet address of user M;
the established correspondence between the blockchain ID of the user M and the wallet address can be shown as the following table:
therefore, by taking each public key in the remaining public and private key pairs except the target public and private key pair in the multiple groups of public and private key pairs as the wallet address of the user, the corresponding relation between the block chain ID and the wallet address is established and stored, the block chain ID of the user is associated with the wallet address, the user to which each wallet address belongs is determined, and other users can know the user to which each virtual wallet belongs.
It is to be understood that a user may conduct transactions with other users in the blockchain, as well as communicate information with other users in the blockchain.
Generally, after receiving information, a receiving party cannot know which user the information is generated by, that is, cannot judge which user the information interaction is performed with, but according to the block chain ID generation method provided by the embodiment of the present invention, a block chain ID corresponds to a target public and private key pair, and each public and private key pair has a generation path corresponding thereto, that is, a block chain ID may indicate a generating party of the information.
In other words, if the receiving side can know the block chain ID of the received information, that is, which user the received information comes from, the embodiment of the present invention further provides a method for using the block chain ID, which can perform identity authentication on the generating side of the information.
Referring to fig. 4, a flow chart of a method for using a block chain ID according to an embodiment of the present invention is shown, where the method includes:
s401: and receiving the information to be authenticated and the block chain ID.
The information to be authenticated is information obtained by encrypting the information to be transmitted by the generator using a target private key corresponding to the blockchain ID of the generator, for example, the generator calculates by using a hash function to obtain a digest of the information to be transmitted, encrypts the digest of the information to be transmitted using a private key corresponding to the blockchain ID to obtain a generator signature, uses the information to be transmitted and the generator signature as information to be authenticated, and transmits the information to be authenticated and the blockchain ID.
The blockchain ID is obtained by encoding a public key of a target public and private key pair in the generated multiple groups of public and private key pairs according to a blockchain ID creation request of a certain user.
It can be understood that if the information to be authenticated is generated by the user corresponding to the blockchain ID, the information to be authenticated is the encrypted information of the target private key corresponding to the blockchain ID, and if the information to be authenticated is not generated by the user corresponding to the blockchain ID, the information to be authenticated is not the encrypted information of the target private key corresponding to the blockchain ID.
S402: and acquiring a corresponding target public key according to the block chain ID.
After the block chain ID is obtained, the corresponding target public key may be obtained according to the block chain ID.
For example, the corresponding relationship between each block chain ID and the target public key may be obtained in advance, so that after the block chain ID is obtained, the block chain ID may be searched in the obtained corresponding relationship between each block chain ID and the target public key to obtain the corresponding target public key.
Or, the encoding method when generating the block chain ID may be obtained in advance, so that after the block chain ID is obtained, the corresponding decoding method may be determined according to the encoding method obtained in advance, and the block chain ID may be decoded to obtain the target public key corresponding to the block chain ID.
S403: and authenticating the information to be authenticated by using the target public key corresponding to the block chain ID.
After the corresponding target public key is obtained, the target public key may be used to authenticate the information to be authenticated, for example, the target public key may be used to decrypt the signature of the generator to obtain an authentication digest, a hash function is used to calculate a digest of the information to be transmitted by the generator, and if the digest of the information to be transmitted by the generator is consistent with the authentication digest obtained by decryption, it is determined that the target public key may successfully decrypt the information to be authenticated, and the authentication is successful.
S404: and if the authentication is successful, judging that the information to be authenticated is the information encrypted by using a target private key corresponding to the block chain ID, and taking the block chain ID as the identity information of the information to be authenticated.
If the target public key can successfully decrypt the received information to be authenticated, the information to be authenticated is the encrypted information of the target private key corresponding to the block chain ID, in other words, the generator of the information to be authenticated is the user corresponding to the block chain ID. If the decryption fails, it is proved that the information to be authenticated is not the information encrypted by the target private key corresponding to the blockchain ID, that is, the information to be authenticated is not from the user corresponding to the blockchain ID.
Therefore, the purpose of carrying out identity authentication on the information to be authenticated based on the block chain ID is achieved.
As can be seen from the above, the block chain ID using method provided by the present invention is implemented by encrypting, by a generator, a private key corresponding to its own block chain ID, sending the encrypted information to be authenticated to a receiver, enabling the receiver to use the received block chain ID, determining a target public key corresponding to the received block chain ID, authenticating, by using the target public key, the identity of the generator of the information to be authenticated, and determining whether the generator of the information to be authenticated is a user corresponding to the received block chain ID.
Meanwhile, in the related art, if the identity of the generator of the information to be authenticated is required to be determined, the information to be authenticated needs to be decrypted, the decrypted information is analyzed, and the identity information of the generator of the information to be authenticated is extracted from the decrypted information.
