Embodiment
Fig. 1 is the implementation method flow chart of block chain node provided in an embodiment of the present invention.The embodiments of the invention provide
The implementation method of block chain node, it is as follows that the method comprising the steps of：
Step S101, service end receives random number, very first time stamp and the first cryptographic Hash that client is sent.
In the present embodiment, user equipment is for example provided with the client of block chain on intelligent mobile terminal, and network side is set
The standby service end that consistently online is for example provided with server, client and service end can communicate.
Network side equipment such as server carries out the initialization of service end, and after the initialization, service end has following function：
1) peer-to-peer network (Peer to Peer, abbreviation P2P) is accessed.
2) transmission to be broadcast the message receives and processing.
3) acquisition of book keeping operation power is calculated and grabbed, and obtains corresponding reward (for example, the reward of ore deposit is dug in the absence from work without reason of bit coin).
4) account book is stored.
5) public key of memory block chain node.
Intelligent mobile terminal is downloaded and installs the client of block chain, after installing, starts the client, generates area
The public key and private key of block chain node.In the present embodiment, intelligent mobile terminal can be used as a block chain node.Intelligent mobile
The client for the block chain installed in terminal has following function：
1) initiation and confirmation of some transaction.
2) signature of electronic contract.
3) private key of memory block chain node.
The client of intelligent mobile terminal carries out interconnection first with the service end of network side equipment such as server and operated, visitor
Family end sets initialization entry password in service end, and uploads the public key of block chain node simultaneously to service end.Service end is received
To after entry password and public key, service end stores the entry password and public key, then replys successful information to client, represents
" shaking hands " success.
Client carries out Hash operation to entry password, random number, very first time stamp, obtains the first cryptographic Hash HASH1, so
Random number, very first time stamp and the first cryptographic Hash are sent to service end afterwards.
Step S102, the password that logs in that described service end was stabbed and prestored to the random number, the very first time enters
Row Hash operation, obtain the second cryptographic Hash.
Service end is verified to random number, very first time stamp and the first cryptographic Hash, specifically, during to random number, first
Between stab and prestore log in password carry out Hash operation, obtain the second cryptographic Hash HASH2.
If step S103, described first cryptographic Hash and second cryptographic Hash are equal, stepped on described in the service end determination
Land password is correct.
If HASH1=HASH2, prove the client to log in password correct, perform step S104, otherwise it is assumed that
The client is assault, records the MAC Address of other side, and discard processing is done in the message cut-off for the MAC Address later.
Step S104, described service end receives the encryption information that client is sent, and the encryption information is the client
The information obtained after the first information and the second information are encrypted using session key, the first information are included：Transaction letter
Breath, the second timestamp and the 3rd cryptographic Hash, second information are that the client utilizes the private key of block chain node to described
The information that the first information obtains after being signed, the 3rd cryptographic Hash are that the Transaction Information and second timestamp are entered
The cryptographic Hash that row Hash operation obtains.
When client actively initiates some transaction, client is required connect in network, and client is to the transaction
Physical contents signed with the private key of block chain node, specifically, using the private key of block chain node to Transaction Information,
Two timestamps and the 3rd cryptographic Hash are signed, and in the present embodiment, Transaction Information, the second timestamp and the 3rd cryptographic Hash are remembered
For the first information, Transaction Information, the second timestamp and the 3rd cryptographic Hash will sign using the private key of block chain node
To signing messages be designated as the second information, wherein, the 3rd cryptographic Hash is to the Transaction Information and second timestamp
Carry out the cryptographic Hash that Hash operation obtains.The first information and the second information are encrypted using session key for the client, are obtained
Service end is sent to encryption information, and by the encryption information.
Step S105, the encryption information is decrypted using the session key to obtain described first for described service end
Information and second information.
The first information and second information are sent in peer-to-peer network by step S106, described service end.
After service end receives encryption information, the encryption information is decrypted to obtain using the session key described
The first information and second information, that is, Transaction Information, the second timestamp and the 3rd cryptographic Hash are obtained, and utilize block chain link
The signing messages that the private key of point is signed to obtain to Transaction Information, the second timestamp and the 3rd cryptographic Hash.Service end will merchandise
Information, the second timestamp and the 3rd cryptographic Hash, and using block chain node private key to Transaction Information, the second timestamp and the
The signing messages that three cryptographic Hash are signed to obtain is sent in P2P networks, can be specifically broadcast in P2P networks.
In addition, when client need not initiate transaction, client and intelligent mobile terminal can keep offline
State, saves the battery and surfing flow of intelligent mobile terminal, and avoid simultaneously it is always in the state of easily by hacker
The safety problems such as attack.
Service end is always maintained at presence, grabs book keeping operation power in real time in a network, and obtains reward, and stores account
This etc..
The embodiment of the present invention is signed Transaction Information by client, and the information after Transaction Information and signature is entered
Row encryption, and encryption information is sent to service end, service end is decrypted to encryption information using session key and merchandised
Information, and send transaction information in peer-to-peer network, improve the security of client so that intelligent mobile terminal can be made
For block chain node, and improve personal information in intelligent mobile terminal and pay the security of category information.
