In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing the present invention is made into
One step it is described in detail, it is clear that described embodiment is only embodiment of the invention a part of, rather than whole implementation
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belongs to the scope of protection of the invention.
The technical scheme that the embodiment of the present invention is provided is applied to most block catenary systems, and block catenary system is a kind of
Acentric network system, most common is bit coin network system.Fig. 1 is a kind of bit coin provided in an embodiment of the present invention
The simple system architecture for showing bit coin network, bit coin net in actual applications in network system architecture schematic diagram, Fig. 1
Network system architecture can be more much more complex than shown in Fig. 1.As shown in figure 1, bit coin network system is made up of multiple terminals, in the system
In and in the absence of central server or the equipment with similar functions, each terminal in system is " equality ", all may be used
To build, send and receive Transaction Information.If terminal bit coin network to be added, need to install specific in the terminal
Bit coin software, when bit coin running software, the terminal just adds bit coin network.Terminal is in bit coin network system
In the presence of a unique address, this address can be voluntarily inputted by user by bit coin Software Create after a string of characters,
It is portable with transacting targeted address information in Transaction Information when the transaction of bit coin is carried out between terminal.According to transacting targeted
Address information, bit coin network system takes midsequent forward mode to transmit Transaction Information, i.e., when a system node receives one
After individual Transaction Information, the transacting targeted address information in Transaction Information judges whether it is the address information of oneself, if not
It is then to broadcast the Transaction Information to neighbouring system node.Bit coin network system is a kind of relatively conventional block linkwork
System, in addition to bit coin network system, such as the other digital coin systems in ether mill also all have similar principle and feature,
It should be included among the embodiment of the present invention.
Based on the above-mentioned block catenary system framework by taking bit coin network system as an example, the embodiment of the present invention provides a kind of information
Sending method.Fig. 2 is a kind of method for sending information schematic flow sheet provided in an embodiment of the present invention, as shown in Fig. 2 including following
Step：
S201：Receive the information to be transmitted and transmission objectives of user's input.
S202：The encryption key of transmission objectives is obtained, and information to be transmitted is encrypted using encryption key.
S203：Using the information to be transmitted after encryption as the first Transaction Information additional information parameter；First Transaction Information
It is transacting targeted different from transmission objectives；The service charge parameter of first Transaction Information is set to the first particular value, the first particular value
For indicating that the accounting nodes in block catenary system do not record the first Transaction Information.
S204：First Transaction Information is sent by block catenary system.
In specific implementation process, block catenary system can be bit coin network system or ether mill network system,
Can also be block catenary system for specially being built for anonymous transmission, etc., the embodiment of the present invention is not construed as limiting to this.It is optional
, block catenary system is bit coin network system, bit coin network system is that current coverage is most wide, it is the most ripe to develop,
The block catenary system that operation is stablized the most, technical scheme provided in an embodiment of the present invention may be directly applied to bit coin network system
In, the above-mentioned advantage of bit coin network system can be made full use of, what the performance embodiment of the present invention was brought to the full extent carries
The technique effect of high anonymous communication anonymity.When Transaction Information is transmitted in block catenary system, generate the Transaction Information is
System node is sender, and the system node of any one non-sent side can serve as the transmission node of the Transaction Information, and pass
Defeated target is then one in numerous transmission nodes of the Transaction Information.
In S201, information to be transmitted is that user is intended to the anonymous information for being transferred to transmission objectives.For example, user A is intended to
User B " 4 park entrances will be shown in tomorrow afternoon " is informed, then, the system node corresponding to user A is sender, information to be transmitted
It is " 4 park entrances will be shown in tomorrow afternoon ", and the system node corresponding to user B needs to receive the information to be transmitted
Transmission objectives.
In S202, the encryption key of transmission objectives can sender by under line or other avenues of communication are obtained,
It should ensure that encryption key can not be known by third party in objective.Encryption key can sender and transmission objectives arrange in advance
The key pair that private key, encryption and decryption are all carried out using this private key or sender arranges with transmission objectives
In encryption key or transmission objectives public key address, wherein, public key address is in block catenary system equivalent to system section
Dot address, is the identity of user in block catenary system, system node is by block chain software (in such as bit coin network system
Bit coin software) generation public key address and private key corresponding with the public key address, the public private key pair is one in block catenary system
As be used for the purposes such as authentication, digital signature.
In S203, additional information parameter can be provided with the Transaction Information of block catenary system, is commonly used in record and hands over
The information to be transmitted after encryption is regard as the attached of the first Transaction Information in the information such as easy time, transaction reason, the embodiment of the present invention
Plus information parameter.For example, in bit coin network system, additional information parameter is OP_RETURN parameters, transaction is being built
During information, just need the information record to be transmitted after encryption among OP_RETURN parameters.It is noted that Transaction Information
Transacting targeted different from transmission objectives, for example, user A transmits message to user B, then the transmission objectives of Transaction Information is user B,
And the transacting targeted of Transaction Information is user C.Optionally, can be by the way that the transaction address information in Transaction Information be set to use
Family C address information is realized, can also arbitrarily input any transaction address information, because the purpose of this Transaction Information is real
Existing message transmissions of the user A to user B, and it is not necessary to guaranty that this Transaction Information is bound to realize between user A and other users
Process of exchange.Certainly, directly user A is concealed in user D and user C or user A and user C to the user B message transmitted
Between arm's length dealing information in method, be also contained in the embodiment of the present invention, the application is no longer repeated this one by one.
In block catenary system, especially block chain digital coin systems, there are all friendships in system in the presence of a record more
The public account book of easy information, this account book is combined by the account book of each system node, and anyone can read public
Additional information parameter in the Transaction Information that account book is recorded.Although the additional information of the first Transaction Information in the embodiment of the present invention
Parameter is information to be transmitted after transmission objectives encryption keys, and attacker can not decrypt, but attacker still can be with
Malice screening is carried out to the Transaction Information in public account book according to some features of additional information parameter, this drops to a certain extent
The anonymity of low communication.Therefore, in S203, the service charge parameter of the first Transaction Information is set to the first particular value, first
Particular value is used to indicate that the accounting nodes in block catenary system do not record the first Transaction Information.In block catenary system, in order to protect
The uniformity of each system node account book is demonstrate,proved, a system node can be elected by block chain agreement and is used as accounting nodes, by
Transaction Information is recorded in public account book by the node, afterwards, and accounting nodes send other nodes in broadcast notice system and hand over this
Easy information is recorded in respective account book, and collects certain service charge.Only after Transaction Information is recorded in public account book,
Just think that the Transaction Information comes into force.Under normal circumstances, accounting nodes are the sequential processes transaction according to service charge from high to low
Information, i.e. the higher Transaction Information of service charge parameter is more first handled, the slower processing of the lower Transaction Information of service charge, works as transaction
When information is not recorded in public account book by accounting nodes within a certain period of time, just think that this Transaction Information is failed.It is of the invention real
Apply in example, service charge parameter is set to the first particular value, such as 0, i.e. not payment procedure takes or other relatively low numerical value, and or
Any form of illegal field of person so that accounting nodes do not handle the first Transaction Information for a long time, until the first Transaction Information loses
Effect, so that avoiding the first Transaction Information is written into public account book.Certainly, the failure of the first Transaction Information does not represent the system
In other nodes no longer transmit the Transaction Information, the Transaction Information, which remains unchanged, to be transferred to transmission objectives by block catenary system.
In S204, sender sends Transaction Information to block catenary system, will specifically be merchandised using the form of broadcast
Information is sent to neighbouring system node, in neighbouring system node non-transmitting target, by neighbouring system node continue into
Row broadcast forwarding, i.e. relay forwarding.Because block catenary system is used in relay forwarding pattern transmission information, block catenary system
Almost all of system node will all receive this Transaction Information.
Corresponding with above- mentioned information sending method, the embodiment of the present invention also provides a kind of information processing method.Fig. 3 is this
A kind of information processing method schematic flow sheet that inventive embodiments are provided, as shown in figure 3, comprising the following steps：
S301：Transmission node receives the Transaction Information that the transmission of block catenary system comes；The transacting targeted and transmission of Transaction Information
Target is different；The additional information parameter of Transaction Information is the information to be transmitted after the encryption keys using transmission objectives；Hand over
The service charge parameter of easy information is the first particular value, and the first particular value is used to indicate that the accounting nodes in block catenary system are not recorded
Transaction Information.
S302：Transmission node decrypts the additional information parameter in the first Transaction Information using own key, in successful decryption
When, extract the information content in additional information parameter.
S303：When transmission node is accounting nodes, if particular value is the first particular value, Transaction Information is not recorded.
It should be understood that transmission node is any node of non-sent side in block catenary system, it both can be transmission objectives, again
Can be with the conventional system node of right and wrong transmission objectives target.
In S301, transmission node can receive many Transaction Informations, have some to be destined to the biography in these Transaction Informations
Defeated node, there are some not to be destined to the transmission node.Unlike the prior art, the transaction letter of the embodiment of the present invention
What is ceased is transacting targeted different from transmission objectives, and the additional information parameter of Transaction Information is the encryption keys using transmission objectives
Information to be transmitted afterwards.
In S302, transmission node is after Transaction Information is received, except to judge whether oneself is friendship in Transaction Information
Easy target, will also judge whether oneself is the transmission objectives that information to be transmitted is received in Transaction Information.In institute of the embodiment of the present invention
In the Transaction Information of offer, information to be transmitted is carry in its additional information parameter, transmission node after Transaction Information is received, if
Judge oneself whether be Transaction Information transmission objectives, need to first use decryption key decryption Transaction Information in additional information ginseng
Number.Decruption key be with S202, decruption key when information to be transmitted is encrypted corresponding to used encryption key.
Optionally, transmission node can determine caller information according to the sender's public key address information carried in Transaction Information, and then
It is determined that the decruption key of encryption key corresponding with sender.
After additional information parameter is decrypted, a decrypted result can be obtained, optionally, additional information parameter is decrypted
Whether succeed can judge decrypted result according to default standard.For example, the result of successful decryption all possesses certain spy
Levy, such as first 3 are 111, or decrypted result is alphanumeric combined crosswise, or the result of successful decryption is fixed grows
The sequence of degree, or key value made an appointment etc. is included in decrypted result.Certainly, different criterions correspond to hair
The side of sending may need the certain information of correspondence increase, the embodiment of the present invention pair in additional information parameter when building Transaction Information
This is not repeated one by one.In successful decryption, the information content in decrypted result, i.e., foregoing information to be transmitted are extracted.It is optional
, in non-successful decryption, it is not the transmission objectives of the Transaction Information to illustrate this transmission node, now, using the form of broadcast
The Transaction Information is broadcasted to neighbouring transmission node.
It should be understood that transmission node is likely to be the accounting nodes of block catenary system.Therefore, in S303, if transmission node
For accounting nodes, then the particular value in the first Transaction Information determines position of first Transaction Information in processing queue, by
Particular value in the embodiment of the present invention in the first Transaction Information is the first particular value, and accounting nodes will put the first Transaction Information
In the end of processing queue, and after some time, the first Transaction Information not handled yet by accounting nodes fails, from without
Record the first Transaction Information.
In the above-described embodiments, the first Transaction Information is transacting targeted different from transmission objectives so that even if attacker's energy
The incidence relation between block catenary system interior joint address and user real identification is enough cracked, transacting targeted use can only be also obtained
Family true identity, and the user real identification of transmission objectives can not be obtained.Moreover, the first Transaction Information in the embodiment of the present invention
In there is no the address information of transmission objectives, transmission node by whether successful decryption determine whether extract additional parametric information in
The information content, rather than by recognizing that the means of transmission address determine whether to extract the information content in additional information parameter, from
Even and if there is no the address information of transmission objectives in the first Transaction Information, also can guarantee that transmission objectives can be properly received the first friendship
Information to be transmitted entrained by easy information.In addition, by the way that the service charge parameter of the first Transaction Information is set into the first particular value
To avoid the first Transaction Information from writing the public account book of block catenary system by accounting nodes, also avoid attacker and pass through public account
This malice screens the risk of Transaction Information.Therefore, the technical scheme disclosed in the embodiment of the present invention can strengthen anonymous communication
Anonymity.
Further, since the first Transaction Information need not be recorded in public account book, without to accounting nodes payment procedure expense, because
The technical scheme cost that this embodiment of the present invention is provided is lower.
During anonymous communication, if using always with a pair of encryption keys and decruption key, it can exist and be cracked
Risk.Optionally, transmission Transaction Information is all updated to current encryption key according to preset rules each time, using renewal
Information to be transmitted is encrypted encryption key afterwards.For example, current encryption key is A, preset rules are " current
Jia 2 on the basis of encryption key ", then the encryption key after updating is A+2, is carried out after a Transaction Information transmission, when again
During transmission, current encryption key is A+2, is updated according to preset rules, and the encryption key after being updated is A+4.Phase
Answer, decruption key is also required to the renewal synchronized.For example, there are default rule between system node A and system node B
Then 1, then system node A used after the information to be transmitted after receiving being encrypted according to encryption key 1 of system node B transmissions
The successful decryption of decruption key 1, and extract information to be transmitted；Afterwards, decruption key 1 is updated according to preset rules 1, obtains decryption close
