Description
Technical field
The present invention relates to the relevant technology of block chain more particularly to the methods of block chain agent authorization, medium.
Background technique
Block chain (Blockchain) is derived from the Floor layer Technology of bit coin, be it is a kind of sequentially in time by data block with
A kind of linked data structure that the connected mode of sequence is combined into, and can not distorting of being guaranteed in a manner of cryptography and can not be pseudo-
It makes, realizes the distributed account book of decentralization.
Node is the basic unit for forming block chain network, and the corresponding computer of a general node saves account book
Copy can serve as different role, such as issue transaction, verifying transaction, book keeping operation.Participant of the node as block catenary system,
A data copy is safeguarded respectively.Node keeps the consistency of backup database data by common recognition algorithm.Due to block linkwork
System is the distributed account book system of decentralization, independent of any trusted third party, so needing a kind of without relying on the
Tripartite mechanism identifies and verifies the mechanism of a certain numerical value or transaction, i.e. common recognition mechanism.Common recognition mechanism is all block chains and divides
The basis of cloth account book application.Each account is made of address (public key) and private key in block catenary system.User by using
Private key controls the assets in account, i.e. user signs to the operation of assets using private key.In block catenary system, user
The ownership of account assets is determined by possessing the private key of account completely.I.e. user is by private key signature to the money of the account
Production is operated.
Under actual business model there are user by part delegation to the scene of other users.Such as alliance's chain
It is close in user in (only the block chain network open to specific individual or entity, the disengaging of network node are strictly managed)
When key is lost or is dead, need that core node is entrusted to transfer assets.The solution for currently meeting the demand is by user's private
Key consigns to trustee completely, or private key is backed up in core node in advance.Such methods are actually by the institute of account
It has the right to consign to trustee completely, and specific permission control cannot be carried out to trustee.In alliance's chain, user needs
Key is provided and gives service for change；Or after password loss, assets transfer service is provided.It, can only in existing block chain technology
The private key of user is backed up at core node.But this method assigns core node excessive right, is not able to satisfy visitor
Family demand.
Although this method can solve the demand of delegation, but trustee can actually fully control account, or even can
To carry out violating the operation of consigner's wish.
The concept of allograph was proposed by Mambo et al. in 1996.Allograph allows user A to press the right of signature
User B need to be entrusted to.In commission range, user B can sign to message with the name of A.Verifier can screen this
Signature is to be carried out by A commission in B, and verify the correctness of signature.
Intelligent contract is the one section of code operated on block chain, it can maintain the state of oneself, the money to draw oneself up
It produces and the external information or assets that receive is responded, code control and management database.The assets of each account
Be stored in the database of intelligent contract, and can by intelligent contract under the conditions of meeting specific to the data in database
Operated (as shown in Figure 1).Under normal circumstances, intelligent contract can check whether the signature of a transaction is correct first, verifying
By rear, assets in database can just be operated.Account can be guaranteed to the control of oneself assets in such a way.
In alliance's chain, the common mode of agent authorization is to confer to the right that core node controls all nodes.Intelligent contract is examined first
The signature of transaction is looked into, if the signature is the effective signature provided by initiator or core node, executes code update number
According to library.But the shortcomings that this method, is, regular account has entrusted excessive permission to core node.
Summary of the invention
A brief summary of one or more aspects is given below to provide to the basic comprehension in terms of these.This general introduction is not
The extensive overview of all aspects contemplated, and be both not intended to identify critical or decisive element in all aspects also non-
Attempt to define the range in terms of any or all.Its unique purpose is to provide the one of one or more aspects in simplified form
A little concepts are with the sequence for more detailed description given later.
The invention proposes a kind of block chain agent authorization method based on allograph (Proxy Signature), it is situated between
The right of part can be entrusted to trustee by matter, user, and can specify range, the timeliness etc. of commission right.?
In alliance's chain, assets transfer can be carried out in the case where user's Lost Security Key.Meanwhile the agent authorization method energy minimization core
