Node.
By taking the alliance's catenary system for netting loan business as an example, regulatory agency, bank, insurance etc. financial institutions can usually keep steady
It is scheduled on line, can be used as accounting nodes;The mechanisms such as common lending agency, P2P fund provider can be used as general node.
It further, is obligated and need for the non-accounting nodes in the catenary system that coalizes due to the needs of supervision
It asks and the data of oneself is stored on chain, so that the later period checks and checks.For example, in alliance's catenary system of net loan business
In, for non-accounting nodes (such as lending agency, P2P fund provider in each alliance's catenary system that net loan business is added
Deng), which can be strictly required each non-accounting nodes by local data (contract such as signed with client) cochain.And
In this course, how the technical issues of a kind of safe data transmission method for uplink becomes urgent need to resolve in the prior art is provided.
Based on system architecture shown in fig. 1, the embodiment of the present invention provides a kind of data transmission method for uplink, provides one kind to realize
The data method of safety.As shown in Fig. 2, being process signal corresponding to a kind of data transmission method for uplink provided in an embodiment of the present invention
Figure, specifically comprises the following steps:
Step 201, non-accounting nodes are written into data and are divided into N number of deblocking.
Step 202, for any data piecemeal, non-accounting nodes are if it is determined that be stored with the first number in alliance's catenary system
According to piecemeal, then encryption accounting nodes are determined from the first accounting nodes.
Step 203, non-accounting nodes encrypt the second deblocking using the public key of the encryption accounting nodes.
Step 204, non-accounting nodes send the public key of encrypted second deblocking and the encryption accounting nodes
To alliance's catenary system, up to N number of deblocking, there are at least two data after storing to alliance's catenary system
Piecemeal is encrypted using the public key of different encryption accounting nodes.
Using the above method, the full content that non-accounting nodes can be written into data is sent in alliance's catenary system,
So that alliance's catenary system stores this, in this way, alliance's catenary system is still deposited even if non-accounting nodes lose data to be written
Contain data to be written;Further, the embodiment of the present invention can be written into data and be divided into multiple deblockings, also,
At least two deblockings are encrypted using the public key of different encryption accounting nodes respectively, even if adding in this way, there is some
The case where Key Exposure of close accounting nodes, can not decode the total data piecemeal of data to be written, completely also so as to have
Effect prevents accounting nodes keeping key to be not good at or key malice leakage bring risk, and then improves in alliance's catenary system number
According to the safety of transmission.
Specifically, in step 201, non-accounting nodes locally can store a plurality of data to be written.For example, non-book keeping operation
The contract signed with every client that node is locally stored can be used as a data to be written, alternatively, other can also be counted
According to as data to be written, specifically without limitation.It should be noted that being directed to every data to be written, can carry out above-mentioned
Step described in step 201 to step 204.
In the embodiment of the present invention, there are many modes that non-accounting nodes divide data to be written, for example, can be
Impartial division is carried out to data to be written, that is, the data volume that each deblocking after dividing includes is equal;Alternatively, can also be right
Data to be written carry out unequal division, that is, the data volume that each deblocking after dividing includes can be unequal, specifically not
It limits.
By taking non-accounting nodes carry out impartial division to data to be written as an example, specific division mode also there are many.One
In example, if N=4, the binary coding of data to be written is " 0100101110110101 ", then can be by the way of jumping position
The data to be written are divided.It is specific as shown in table 1, it is a kind of example of deblocking.Wherein, the 1st deblocking
For " 0110 ", the 2nd deblocking is " 1001 ", and the 3rd deblocking is " 0110 ", and the 4th deblocking is " 0111 ".
A kind of table 1: example of deblocking
Data to be written | 1st deblocking | 2nd deblocking | 3rd deblocking | 4th deblocking |
0100101110110101 | 0110 | 1001 | 0110 | 0111 |
Specific division mode is, is the corresponding binary-coded example of data each position to be written as shown in table 2.
1st deblocking may include 1st, the 5th, the 9th and the 13rd corresponding binary coding of data to be written, i.e., and
1 deblocking is " 0110 ";2nd deblocking may include data to be written 2nd, the 6th, the 10th and the 14th
Corresponding binary coding, i.e. the 2nd deblocking are " 1001 ";3rd deblocking may include data the 3rd to be written
Position, the 7th, the 11st and the 15th corresponding binary coding, i.e. the 3rd deblocking are " 0110 ";4th deblocking
It may include 4th, the 8th, the 12nd and the 16th corresponding binary coding of data to be written, i.e. the 4th deblocking
For " 0111 ".
Table 2: the corresponding binary-coded example of data each position to be written
Using this data division mode, even if there is the case where deblocking is divulged a secret, due to including in deblocking
Binary coding is to jump position to choose, and is that can not accurately know in intercepted and captured deblocking for criminal therefore
Including specific location of each binary coding in former data, and then also can not just obtain the content of former data, further mention
The high safety of data.
In another example, if N=4, the binary coding of data to be written is still " 0100101110110101 ", can also
The data to be written are divided in a manner of using non-jump position.Specifically, the 1st deblocking may include number to be written
According to the 1st to the 4th corresponding binary coding, i.e. the 1st deblocking is " 0100 ";2nd deblocking may include
5th to the 8th corresponding binary coding of data to be written, i.e. the 2nd deblocking are " 1011 ";3rd deblocking
It may include 9th to the 12nd corresponding binary coding of data to be written, i.e., the 3rd deblocking is " 1011 ";4th
Deblocking may include 13rd to the 16th corresponding binary coding of data to be written, i.e. the 4th deblocking is
“0101”。
In other possible examples, those skilled in the art can also rule of thumb and actual conditions, using other strokes
Point mode divides data to be written, specifically without limitation.
In the embodiment of the present invention, N can be the integer greater than 1;Further, it is contemplated that during subsequent step requires, own
Deblocking will not be recorded by the same accounting nodes, and therefore, N may be the integer greater than 2.
Further, it is contemplated that in practical operation, there are the possibility that part accounting nodes are offline or break down, this hairs
For bright embodiment before executing above-mentioned steps 201, non-accounting nodes can also be according to accounting nodes each in alliance's catenary system
Status information determines the quantity M of effective accounting nodes;N is less than or equal to M, and M is the integer greater than 1.Wherein, effectively book keeping operation saves
Point is current time online and operational excellence accounting nodes in alliance's catenary system.Further, N can be according to alliance
The quantity of effective accounting nodes determines in catenary system, and in other words, N can be for greater than 2, and are less than or equal to effective accounting nodes
The integer of quantity, for example, the quantity of effectively accounting nodes is 4, then N can be 4.
In step 202 to step 203, for any data piecemeal in N number of deblocking, non-accounting nodes can first be sentenced
The first deblocking whether is stored in disconnected alliance's catenary system, wherein the first deblocking is at least one of data to be written
Deblocking.For example, if data B to be written is divided into 4 deblockings, indicated respectively with B1, B2, B3 and B4 this 4
A deblocking.In this way, be directed to any data piecemeal, such as B2, non-accounting nodes can first judge in alliance's catenary system whether
It is stored at least one deblocking at least one of (i.e. in B1, B3, B4) of data B to be written.
Further, non-accounting nodes, then can be by if it is determined that not stored in alliance's catenary system have the first deblocking
One deblocking is sent in alliance's catenary system;In turn, each accounting nodes in alliance's catenary system can be obtained by competition mechanism
The record of the first deblocking is taken to weigh.
Non- accounting nodes, then can be from the first accounting nodes if it is determined that be stored with the first deblocking in alliance's catenary system
Determine encryption accounting nodes, wherein the first accounting nodes can be the accounting nodes with first deblocking record power;
In turn, the public key that encryption accounting nodes can be used in non-accounting nodes encrypts the second deblocking, wherein the second data
Piecemeal can be any data piecemeal in N number of deblocking in addition to the first deblocking.
In the embodiment of the present invention, non-accounting nodes are determined there are many modes of encryption accounting nodes.A kind of possible realization
Mode is the sequencing that non-accounting nodes record the first deblocking according to the first accounting nodes, is kept accounts to first
Node is ranked up, and accounting nodes the last in the first accounting nodes after sequence are determined as to encrypt accounting nodes.
For example, for deblocking B2, non-accounting nodes if it is determined that be stored with deblocking B1 in alliance's catenary system,
It then can first determine the accounting nodes with B1 record power;For the system architecture shown in Fig. 1, if accounting nodes 1011 have
There is the record of B1 to weigh, then can determine that the first accounting nodes are accounting nodes 1011;It is possible to further determine accounting nodes
1011 be encryption accounting nodes.
By way of further example, for deblocking B3, non-accounting nodes are if it is determined that be stored with deblocking in alliance's catenary system
B1, deblocking B2 then can first determine the accounting nodes with B1, B2 record power;It is with system architecture shown in Fig. 1
Example, if accounting nodes 1011 are weighed with the record of B1, accounting nodes 1012 are weighed with the record of B1, then can determine the first book keeping operation
Node is accounting nodes 1011 and accounting nodes 1012;It is possible to further according to accounting nodes 1011 and accounting nodes 1012
The sequencing that deblocking B1 and deblocking B2 are recorded respectively, to accounting nodes 1011 and accounting nodes 1012 into
Row sequence;If accounting nodes 1011 first record deblocking B1, deblocking B2 is remembered after accounting nodes 1012
Record can then determine accounting nodes 1012 for encryption accounting nodes.
Alternatively possible implementation is that non-accounting nodes can be chosen not yet from the first accounting nodes as encryption
The accounting nodes of accounting nodes are as encryption accounting nodes.
For example, for deblocking B3, non-accounting nodes if it is determined that be stored in alliance's catenary system deblocking B1,
Deblocking B2 then can first determine the accounting nodes with B1, B2 record power;For the system architecture shown in Fig. 1, if
Accounting nodes 1011 are weighed with the record of B1, and accounting nodes 1012 are weighed with the record of B1;Further, if deblocking B1 not
Encryption, deblocking B2 is encrypted using the public key of accounting nodes 1011, i.e., accounting nodes 1011 have been made before this
To encrypt accounting nodes, and accounting nodes 1012 can then determine accounting nodes before this not yet as encryption accounting nodes
1012 as encryption accounting nodes.
In other possible implementations, those skilled in the art, which can also rule of thumb determine with actual conditions, to be added
Close accounting nodes, for example can determine that an accounting nodes are encryption accounting nodes from the first accounting nodes at random, specifically not
It limits.
Further, after determining encryption accounting nodes using the above method, non-accounting nodes can also use encryption
The public key of accounting nodes encrypts the second deblocking, and by encrypted second deblocking and encrypts accounting nodes
Public key is sent in alliance's catenary system, if ensure all deblockings after being sent in alliance system, alliance's linkwork
There are at least two deblockings after system is encrypted using the public key of different accounting nodes.
Specifically, non-accounting nodes can by the way of asymmetric encryption encrypt the second deblocking, i.e., directly
It connects and the second deblocking is encrypted using the public key of encryption accounting nodes;Alternatively, non-accounting nodes can be added using symmetrical
Close mode encrypts the second deblocking, for example, non-accounting nodes can first with one it is small go here and there the string T generated at random, it is right
Deblocking B2 carries out symmetric cryptography (data after secret are T (B2)), is then carrying out asymmetric encryption to T with public key G1
(G1 (T)) correspondingly during being decrypted, can first take out T (B2) and G1 (T), first with the private key S1 of G1 to G1
(T) it is decrypted, after obtaining T, then T (B2) is symmetrically decrypted, to obtain original deblocking B2.
Further, in order to more improve the safety that data store, the embodiment of the present invention can make each book keeping operation
Node records a deblocking respectively, and non-accounting nodes can be by encrypted second deblocking and encryption accounting nodes
Public key is sent in alliance's catenary system each accounting nodes in addition to the first accounting nodes.For example, above-mentioned for data point
In the example of block B3, non-accounting nodes are if it is determined that accounting nodes then can be used to encrypt accounting nodes in accounting nodes 1012
1012 public key encrypts deblocking B3, and the public key of encrypted B3 and accounting nodes 1012 are sent in Fig. 1
Accounting nodes (i.e. 1013 He of accounting nodes in the alliance's catenary system shown in addition to accounting nodes 1011 and accounting nodes 1012
Accounting nodes 1014).
In this way, enable to the single or several accounting nodes in alliance's catenary system (only not every
Accounting nodes) data to be written can not be decoded out, and then the true content of data to be written can not be also obtained, so as to effective
Prevent accounting nodes keeping key be not good at or key leakage after bring risk.
Based on same inventive concept, the embodiment of the present invention also provides a kind of date storage method.It as described in Figure 3, is this
The corresponding flow diagram of a kind of date storage method that inventive embodiments provide, specifically comprises the following steps:
Step 301, accounting nodes receive information to be stored.
