Description
Technical field
The present invention relates to the means of communication, and in particular to a kind of communication means based on block chain.
Background technique
Current numerous Internet chat tools are satisfied with people and are linked up simultaneously, also expose some serious problems, such as safe
Property；Traditional centralization communication pattern is easy to be attacked, and individual privacy is caused to be revealed, and the network of C/S framework exists centainly
Information risk of missing.
Block chain technology is brought into the visual field of people by the birth of bit coin；Block chain network based on p2p agreement provides nothing
Third party's credit underwriting, decentralization, distribution, the environment that can not be distorted are needed, using powerful cryptographic algorithm, is built for communication
Base oneself upon the basic condition of enough secure and trusted, anonymous, anti-monitoring.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of communication means based on block chain.
In order to solve the above-mentioned technical problem, first technical solution according to the present invention, a kind of communication based on block chain
Method, it is characterised in that: the means of communication carry out as follows:
Step 1: establishing several clients in block chain network, client is divided into full information client side and light passenger train family
End；Full information client side is the client for storing the whole network message；Light client is the related news for only storing this client
Client；
Step 2: distributing mailing address to each full information client side and light client, mailing address is to be calculated using encryption
The public private key pair that method generates, wherein private key is stored in local, and public key is externally announced as the address for receiving message.
Step 3: sending message local communication address corresponding private of the client to transmission of message when sending message
Key is signed, and using the corresponding public key encryption source body of mailing address of recipient, is converted to ciphertext, ciphertext is as friendship
Easy additional content is broadcasted to the full information client side of each of block chain network.
Step 4: after full information client side receives ciphertext, ciphertext is packaged into block data, then by block data broadcast to
Each of block chain network client.
Step 5: judging whether the block data is destined to local communication after each client receives block data
Address, if being destined to local communication address, six are entered step, if not being sent to local communication address, into
Enter step 7.
Step 6: after successful decryption, showing that message is simultaneously deposited using the corresponding private key decryption block data in local communication address
It puts into local message library, enters step eight.
Step 7: judge whether this client is full information client side, it, will if this client is full information client side
Block data storage, enters step eight；If this client is not full information client side, eight are entered step.
Step 8: terminating.
The preferred embodiment of a kind of communication means based on block chain according to the present invention, to each full information client side
N number of mailing address is distributed with light client, N is positive integer.
A kind of beneficial effect of communication means based on block chain of the present invention is: the present invention uses block chain skill
Art is established the communication means of credible, anonymous, the anti-monitoring of a set of safe enough, is not needed to take using powerful cryptographic algorithm
Business device, has decentralization, distributed nature, can effectively prevent information risk of missing, is a kind of novel communication means.

Fig. 2 is a kind of communication network composition schematic diagram based on block chain.
Fig. 3 is a kind of communication means schematic illustration based on block chain of the present invention.
Fig. 4 is elliptic curve encryption algorithm flow chart used by step 2 in embodiment.
Specific embodiment
Referring to Fig. 1 to Fig. 3, a kind of communication means based on block chain carries out as follows:
Step 1: establishing several clients in block chain network, client is divided into full information client side and light passenger train family
End.Full information client side is the client for storing the whole network message；Light client is the related news for only storing this client
Client.Information client side and light client are all identical to the processing of message and communication process entirely, and what is only stored disappears
It is different to cease type.Store entire message is full information client side, and only store own customers end related news is light client.
Step 2: distributing mailing address to each full information client side and light client, mailing address is to be calculated using encryption
The public private key pair that method generates, wherein private key is stored in local, and public key is externally announced as the address for receiving message；Wherein encryption is calculated
ECDSA-secp256 elliptic curve encryption algorithm can be used in method, and for details, reference can be made to Fig. 3.
Step 3: customer end A is sender, and customer end B is recipient when customer end A sends message to customer end B；Hair
It send the customer end A of message to sign the message of transmission with the corresponding private key in local communication address, and uses the logical of customer end B
Believe the corresponding public key encryption source body in address, be converted to ciphertext, ciphertext is broadcasted as transaction additional content OP_RETURN to area
The full information client side of each of block chain network.
Step 4: after full information client side receives ciphertext, ciphertext is packaged into block data block, then by block data
Block is broadcasted to each of block chain network client.
Step 5: judging whether the block data is destined to local after each client receives block data block
Mailing address, if being destined to local communication address, six are entered step, if not being sent to local communication address
, enter step seven.
Step 6: after successful decryption, showing that message is simultaneously deposited using the corresponding private key decryption block data in local communication address
It puts into local message library, enters step eight.
Step 7: judge whether this client is full information client side, it, will if this client is full information client side
Block data storage, enters step eight；If this client is not full information client side, eight are entered step.
Step 8: terminating.
In the present embodiment, only customer end B could decrypt block data.So far, customer end A is completed with customer end B
Once based on the communication of block chain encrypted safely, referring to fig. 4.
In a particular embodiment, N number of mailing address can be distributed to each full information client side and light client, N is positive
Integer.
Although an embodiment of the present invention has been shown and described, those skilled in the art can manage the present invention
Solution: without departing from the principle and spirit of the present invention can to these embodiments carry out it is a variety of variation, modification, replacement and
Modification, the scope of the present invention are defined by the claims and their equivalents.
