In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Fig. 1 is a flowchart illustrating an automatic importing method of an account private key of a blockchain wallet according to an embodiment of the present invention, as shown in fig. 1, the automatic importing method of an account private key of a blockchain wallet includes the following steps:
s101, when any user terminal runs a block chain wallet program, a connection relation between the user terminal and any node in a block chain system is established.
That is, when a user of the blockchain system runs the blockchain system wallet program through any user terminal, the connection relationship between the user terminal and any node in the blockchain system is established, so as to link the user terminal into the blockchain system.
Wherein, the user side includes: cell-phone, computer, panel computer and other intelligent terminal equipment.
S102, receiving the private key of the wallet through the user side, signing the query task according to the private key of the wallet, obtaining the public key of the wallet according to the private key of the wallet, and sending the signed query task and the public key of the wallet to the block chain system through the connection relation between the user side and any one node.
That is to say, the blockchain system obtains the private wallet key through the user side, signs the query task according to the received private wallet key, obtains the public wallet key according to the private wallet key, and sends the signed query task and the public wallet key to the blockchain system through the connection relationship between the user side and any one node.
As an example, firstly, a user runs a blockchain wallet program on a new mobile phone, that is, a connection between the new mobile phone and any one node in a blockchain system is established, and then, after the blockchain system is connected with the new mobile phone, the blockchain system receives a wallet private key input by the user through the new mobile phone and signs a query task through the wallet private key so as to encrypt the query task; and calculating a wallet public key corresponding to the wallet private key according to the wallet private key input by the user, and sending the signed inquiry task and the wallet public key to the blockchain system through the connection with any node in the blockchain system.
And S103, when the signed inquiry task is analyzed by adopting the wallet public key to know that the inquiry task is a wallet searching task, acquiring a wallet address according to the wallet public key, and searching an account encryption private key table stored in the block chain system according to the wallet address to obtain all account encryption private keys corresponding to the wallet address, wherein each account encryption private key is obtained by encrypting each account private key by the wallet private key.
That is, after receiving a signed query task and a wallet public key sent by a user side, the block chain system analyzes the signed query task by using the wallet public key to acquire that the task is a wallet searching task, acquires a wallet address according to the wallet public key, namely calculates according to the wallet public key to acquire the wallet address corresponding to the wallet public key, and searches an account encryption private key table stored in the block chain system according to the acquired wallet address to acquire all account encryption private keys corresponding to the wallet address; wherein, each account encryption private key is obtained by encrypting each account private key by the wallet private key.
For example, a query identifier is configured for the query task, and before the query task is signed by using a private key, the query identifier and the query task are packaged together to form a request packet, so that the block chain system can judge the type of the task after analyzing the request packet.
For example, when a wallet creating instruction of a user is obtained, a storage item corresponding to the wallet public key is established in the account encryption private key table, when a subsequent user creates an account, the account private key is encrypted through the wallet private key to form an account encryption private key, the account encryption private key is associated with the wallet public key, and the wallet public key and the account encryption private key are stored in the account encryption private key table, so that the subsequent user can import the private key through the account encryption private key table.
There are various ways to encrypt the account private key with the wallet private key. For example, the DES symmetric key algorithm converts a 64-bit plaintext input block into a 64-bit ciphertext output block, wherein 8 bits are parity bits and 56 bits are the length of the cipher. Or, the RC4 symmetric key algorithm, the principle of the RC4 algorithm is "scrambling", which includes two major parts, namely an initialization algorithm and a pseudo-random sub-cipher generation algorithm, in the initialization process, the key has the main function of randomly scrambling an initial 256-byte cluster, different sub-key sequences can be obtained after different clusters are processed by the pseudo-random sub-cipher generation algorithm, and the obtained sub-key sequences and a plaintext are subjected to exclusive-or (XOR) operation to obtain a ciphertext.
And S104, broadcasting all account encryption private keys corresponding to the wallet addresses in the blockchain system so as to send all account encryption private keys corresponding to the wallet addresses to the user side through the connection relationship between the user side and any one node.
That is, after obtaining all the account encryption private keys corresponding to the wallet address, the blockchain system broadcasts all the account encryption private keys corresponding to the wallet address within the blockchain system, so that a user sending a query request can obtain all the account encryption private keys corresponding to the wallet address through the broadcast.
And S105, at the user side, decrypting each account encryption private key by using the wallet private key to obtain all account private keys, and storing all account private keys to realize that all account private keys are imported from the initial user side to the user side.
That is to say, after receiving all the account encryption private keys corresponding to the wallet addresses broadcasted by the blockchain system through the user side, the users of the blockchain system decrypt each account encryption private key through the wallet private key to obtain all the account private keys, and store all the decrypted account private keys, so as to import all the account private keys from the originating user side to the user side.
In summary, according to the method for automatically importing the account private key of the blockchain wallet of the embodiment of the present invention, first, when any user runs a blockchain wallet program, a connection relationship between the user and any node in the blockchain system is established; then, receiving the wallet private key through the user side, signing the inquiry task according to the wallet private key, acquiring the wallet public key according to the wallet private key, and sending the signed inquiry task and the wallet public key to the block chain system through the connection relation between the user side and any one node; then, when the signed inquiry task is analyzed by adopting the wallet public key to know that the inquiry task is a wallet searching task, acquiring a wallet address according to the wallet public key, and searching an account encryption private key table stored in the block chain system according to the wallet address to obtain all account encryption private keys corresponding to the wallet address, wherein each account encryption private key is obtained by encrypting each account private key by the wallet private key; then, broadcasting all account encryption private keys corresponding to the wallet addresses in the block chain system so as to send all account encryption private keys corresponding to the wallet addresses to the user side through the connection relationship between the user side and any one node; then, at the user side, decrypting each account encryption private key by adopting a wallet private key to obtain all account private keys, and storing all account private keys to realize that all account private keys are led into the user side from the initial user side; therefore, the private key of the user of the block chain system is automatically imported, and the convenience of using the block chain system by the user of the block chain system is improved; meanwhile, information leakage caused by private key storage of a user of the block chain system is avoided.
As shown in fig. 2, in the method for automatically importing an account private key of a blockchain wallet provided by the embodiment of the present invention, when a wallet of a user in a blockchain system is initially created, the method for storing the account private key in the creation process of the initial wallet and an account includes the following steps:
