Embodiment 1
The present embodiment provides a kind of weak center's trust data management methods of the total score double-strand of digital bank, firstly, this
Weak center's trust data management system of the total score double-strand of the digital bank of invention identifies body using asymmetric encryption techniques
Part and ensure safety, i.e., depositor and bank have respective private key and public key, and carried out by digital signature authentication and
Realize the non repudiation of information.For example, depositor ensures the authenticity of transaction request by digital signature, bank passes through number
It signs to ensure the authenticity of system message and receipt of transferring accounts.Meanwhile the registration mode of the virtual digits currency such as similar bit coin,
There is no the CA mechanism (i.e. " certificate authority ") of so-called centralization in digital banking system, the key pair of depositor is by depositor oneself
Generate, the corresponding relationship of public key and account address is completed to map when it carries out Account Registration to bank, private key by depositor from
Oneself takes care of.The asymmetric encryption account management technology of no CA mechanism is to realize the basis of Trusted Digital bank.Compared to existing bank
In system, symmetric cryptosystem is generallyd use based on the absolute trust to bank to protect account safety and carry out identification
Mode, the asymmetric encryption techniques that the present invention uses can arbitrarily forge or usurp to avoid bank using the Information Superiority in hand
Change the transaction record of depositor.The entire flow of a money transfer transactions as shown in Figure 1, wherein in transaction request TX, VA、VBRespectively
Indicate the account of the side of producing Alice and the side of being transferred to Bob, Amount is transfer amounts, Time1For request time, Memo is remarks
Information, SgnAIt is the side's of producing private key to the signature of the request, to confirm the authenticity of the request；It transfers accounts in receipt RE, Time2For
It keeps accounts the time, BalanceAFor the account balance of the side of producing after the completion of transaction, Head_PBAIndicate the chain head of the side's of producing ledger chain
Information, SgncIt is bank's private key to the signature of the transaction, to confirm the completed authenticity of the transaction；It transfers accounts and notifies in Msg
Parameter is similar with RE.The receipt RE and transferring accounts of transferring accounts notifies in Msg that the effect of Head_PB is both the confirmation to currently trading, and
Confirmation to all historical tradings of the depositor.Weak center's trust data management method of the total score double-strand of the number bank,
As shown in Fig. 2, specifically comprising the following steps:
All Activity flowing water is woven into an oriented transaction net according to transaction agent and exchange hour by step 1；
In the oriented transaction net:
Longitudinal is transaction agent, the account information of corresponding depositor；
It is laterally exchange hour, the transaction of all depositors, i.e. the general ledger information of banking system in corresponding timeslice；
Oriented transaction web frame schematic diagram as shown in Figure 3, the timeslice are by the several of the isometric division of exchange hour
Timeslice preferably daily divides, and is set as 24 hours, so as to corresponding with bank existing " journal account ",
In the oriented transaction net: node Vi(i=0,1,2 ..., n) indicates each depositor in unit time piece；Often
One arrow all corresponds to a money transfer transactions；Arrow beginning is the side of producing, and end is the side of being transferred to；Lateral solid line represents different nodes
Between funds flow, longitudinal dotted line represent the remaining sum in the same node flow direction.The oriented transaction net is a constantly growth
Dynamic network, and since new account account constantly has new node to generate.Bank ledger itself is regarded as a special section
Point V0, only one node of original state the whole network V0, other depositor Vi(i=1,2 ..., n) is increasingly incorporated into network in the later period.Regulation
The balance of deposits of all nodes must not drop below zero, bank V0Primary balance be a sufficiently large positive value TB (Total-
Balance), depositor ViThe primary balance of (i=1,2 ..., n) is 0.Since All Activity is all oriented transaction net interior nodes
Between transfer accounts, including depositor Vi(i=1,2 ..., n) depositor V also can be considered to itself account access cashi(i=1,2 ..., n)
With bank V0Between transfer accounts.Therefore, the cash flow in transaction net is a closed loop, and overall balance is consistently equal to constant TB.
Depositor Vi(i=1,2 ..., n) is stored in the cash of X, is equivalent to bank V0To Vi(i=1,2 ..., n) transfer accounts X, i.e., silver-colored
Row V0Itself balance of deposits reduction X, and depositor ViThe balance of deposits of (i=1,2 ..., n) increases X, while cash in bank assets increase
Add X.Similar, depositor Vi(i=1,2 ..., n) extracts the cash of Y, is equivalent to depositor Vi(i=1,2 ..., n) Xiang Yinhang V0Turn
Account Y, i.e. Vi(i=1,2 ..., n) itself balance of deposits reduction Y, and bank V0The balance of deposits increase Y, while cash in bank provide
It produces and reduces Y.Bank V0Primary balance TB it is sufficiently large mean no matter how depositor withdraws deposit, bank V0Remaining sum be forever positive value.
The oriented transaction net is cut into a general ledger chain and several point families from vertical and horizontal both direction respectively by step 2
Account chain；
The logical construction schematic diagram of total score double-strand as shown in Figure 4 specifically further takes out the oriented transaction net
As being cut respectively from vertical and horizontal two dimensions: being laterally general ledger information, longitudinal is account information, forms two kinds of logical datas
Chain: a general ledger chain GC (General-Chain) and several ledger chain PC (Private-Chain)；
Whole system only has a general ledger chain GC, and each depositor has a relatively independent ledger chain PC.Institute
General ledger chain GC is stated, stores information according to block chain structure, each block loads the All Activity in corresponding timeslice, and utilizes front and back
The Hash iteration of block locks historical trading；The ledger chain PC, the transaction data of depositor individual is suitable according to time order and function
Sequence series connection, and the hash chain formed by the calculating mode of formula (1).
Wherein, TXiIndicate the detail of the i-th transaction, BalanceiAccount balance after indicating the i-th transaction；End Hi(i
=n) it is known as the chain head information Head_PC of ledger chain, such as No. 31 squares in Fig. 3 just represent depositor's B node V2Chain head
Information Head_PC.
Step 3, based on the general ledger chain GC, the chain head synchronizing information of all ledger chain PC is incorporated to general ledger chain GC
Block in, so that the general ledger chain GC and ledger chain PC are merged into a BC chain (Binary-Chain)；
The detailed structure view of BC chain as shown in Figure 5:
The BC chain includes several chronologically successive blocks；The block of each BC chain includes the area block Tou He
Block；The block head, for storing the summary info of the block, and the summary info of storage is public to all depositors
It opens；The block body, for storing current detailed trade data.The summary info includes: timestamp, transaction stroke count, hands over
The value (M is one much larger than single trade maximum limit but less than the integer value of unit time piece total transaction amount) of easy total value mould M,
The roots of two Merkel trees (general ledger tree TX_Merkle and ledger tree Head_PC_Merkle) and upper block head
Cryptographic Hash.All block head information of BC chain disclose all depositors, by the distributed storage of the build chain to BC chain, realize
The transaction of all depositors is known together, and then achievees the purpose that implement to supervise to center bank.The build chain of the BC chain is all BC
The data-link that the block head of chain block is constituted.
Current All Activity constitutes general ledger tree TX_Merkle；The general ledger tree TX_Merkle is the Merck of an extension
You set, and each leaf node corresponds to a current transaction TX, and the information of storage includes the cryptographic Hash hash (TX) of the transaction and hands over
Easy volume Amount.Other than the traditional Merkel tree of picture is to cryptographic Hash layer by layer iteration, the SumA field of each node is equal to its most phase
The sum of close turnover of two child nodes mould M.In this way, the Root field of root node has locked current All Activity, simultaneously
SumA*Field is equal to current total turnover mould M.
The chain head information of current all ledger chain PC constitutes ledger tree Head_PC_Merkle；The ledger tree
Head_PC_Merkle is also the Merkel tree of an extension: the account information of corresponding one individual depositor of each leaf node, storage
The content deposited further includes total transaction amount ∑ Amount in the current period account and works as in addition to the chain head information of respective ledger chain PC
Phase ending balance Balance.Corresponding, the Root field of root node has locked the ledger chain PC of current all depositors, simultaneously
SumA**Field be equal to current total turnover twice of value mould M (same transaction can be recorded in the ledger chain of both parties simultaneously
On), SumB field is equal to system overall balance TB.Its quantitative relation is as follows:
Head_PC_Merkle_Root(SumA**)=2 × TX_Merkle_Root (SumA*) %M (2)；
Head_PC_Merkle_Root (SumB)=TB (3)；
Wherein, SumA**It is the field in the tree root Head_PC_Merkle_Root of ledger tree, SumA with SumB**Table
Show the value of the current total transaction amount mould M based on all ledgers statistics, TB indicates the overall balance of system；SumA*For general ledger tree
Field in tree root TX_Merkle_Root, it indicates the value of the current total transaction amount mould M counted based on bank ledger
In conclusion asymmetric encryption techniques ensure that bank can not forge wash sale and directly encroach on depositor's interests,
General ledger tree TX_Merkle has been anchored all transaction, and ledger tree Head_PC_Merkle has been anchored all ledger chain PC,
And every ledger chain PC is the anchor for being anchored every depositor individual transaction.Card and mutually control are deposited by double-strand, in conjunction with numerical value
Verifying, can effectively " latchings " data, prevention bank practise fraud.If only general ledger chain GC, without ledger chain PC, depositor can only
The existence proof of transaction is completed, but the integrality of transaction can not be verified, i.e., bank may " missing " part transaction record.Phase
Instead, if only ledger chain, although depositor is capable of the integrality of individual authentication itself transaction, since ledger chain is each other
Isolated onrelevant, the public, which lacks general ledger data, can not serve as transaction eye-witness, and bank can use the advantage of information asymmetry,
Unilateral account is remembered when manufacturing local true, whole false situation, such as transferring accounts, or is fabricated history to trade using inter-account and be remembered
Record.
Step 4 is verified and transaction verification checks relationship trading and account information by chain head, it is ensured that examination information
Authenticity；The examination is embodied the daily inquiry of its historical trading by depositor；The chain head is verified as verifying BC
The relationship of the chain head information Head_PC of the newest block of chain and itself ledger chain；The transaction verification is to verify itself specifically
The relationship of history block is corresponded in historical trading and the BC chain；
In actual verification process, the verification process of the chain head verifying and transaction verification is refined as the verifying of two classes,
Verifying i.e. to the verifying of data and to system overall data, the former is presented as that existence is verified, and the latter is presented as numerical value
The verifying of relationship:
The chain head verifying is to verify the authenticity of newest block in BC chain: the Merkel on the one hand returned by bank
(Merkle) the chain head information Head_PC of depositor itself is verified by the ledger included in newest block strictly according to the facts in path whether
It sets in Head_PC_Merkle, completes the existence proof of itself Head_PC；On the other hand the whole friendship in newest block is verified
Whether easy data meet the numerical relation of formula (2) and formula (3), i.e., trace back to root from depositor's leaf node in previous ledger tree
During node Head_PC_Merkle_Root, examination SumB whether constant is overall balance TB, SumA**Whether it is equal to newest
" total transaction amount modulus SumA in block head*" twice of value mould M.
The transaction verification is the authenticity for verifying the transaction of certain particular historical: the Merkel on the one hand returned by bank
(Merkle) certain particular transactions TX on itself ledger chain PC is verified by pair included in BC chain strictly according to the facts in path whether
It answers in the general ledger tree TX_Merkle of history block, completes the existence proof of itself particular transactions；On the other hand correspondence is verified to go through
Whether the whole transaction data in history block meets the numerical relation of formula (2) and formula (3), i.e., in previous general ledger tree from transaction
During leaf node traces back to root node TX_Merkle_Root and the block ledger tree is traced back to from depositor's leaf node
During root node Head_PC_Merkle_Root, examination SumB whether constant is overall balance TB, general ledger root vertex
SumA*Whether " total transaction amount modulus SumA in the block head is equal to*" value, the SumA of ledger root vertex**Whether it is equal to
SumA*Twice of value mould M.
Be not difficult to find out from above-mentioned ping procedure, the individual depositor largely dispersed to itself Transaction Information and account data into
While row is directly checked, by cross double-strand to the cross validation of data existence, integrality and numerical relation, realize indirectly
Audit to bank's entirety Transaction Information and accounting data, the possibility for thus greatly reducing bank's altered data, falsifying accounts,
Improve the public credibility of bank.
It should be noted that depositor before carrying out Transaction Inquiries, needs advanced row data synchronous, the block including updating BC chain
The ledger chain PC of head chain and itself, i.e., system newly-increased block head data and itself ledger chain since being downloaded from last time update down
PC new hash chain node.Note that needing to verify the correctness of more new data when data are synchronous, i.e., foundation is previously deposited
The continuity of the data step by step calculation new data of storage sees newest " the build Kazakhstan for the build chain that whether can smoothly derive BC chain
The newest Head_PC of uncommon value " and itself PC.
