Embodiment 1
Decentralization identifier (Decentralized Identifiers, be abbreviated as DIDs), which is that one kind is novel, can verify that
And the digital identity identifier that possesses " self sovereignty ", as a kind of authentication data structure of decentralization, can define people,
The method specification of object and mechanism, decentralization identifier is created by World Wide Web Consortium (W3C), and the appearance of block chain technology is to implement
Decentralization Identity Management provides chance, in decentralization identifier, all identity informations all shapes of account book in a distributed manner
Formula shares trusted node, and each decentralization identifier is protected by the private key encryption of the identity owner, it is acknowledged as to weigh
It is new to define the important safety layer lacked in Internet protocol, i.e. identity layer, traditional identity authentication management system be it is centralized,
And decentralization identifier is totally independent of centralized management center, Third Party Authentication service and certification authority.
Decentralization identifier DIDs is controlled by DIDs theme completely, and independent of any center registration body, identity is mentioned
For quotient or certification authority.The system design of decentralization identifier should be eliminated to centralized registration body and key
The centralized certification authority of management --- the dependence of layering PKI (public key infrastructure) mode standard, since DIDs is stayed
Stay on distributed account book, thus each entity can serve as their own permission root of trust-one kind be referred to as DPKI (go
Centralization PKI) architecture.
DIDs is by DIDs theme URL (Uniform Resource associated with interactive endpoint trusty
Identifier, uniform resource identifier), DIDs resolves to DIDs document, and how specific using this kind of description of DIDs document is
The simple documents of DIDs, each DIDs document include at least three components: encrypted material, authentication external member and service endpoints,
One group is provided for carrying out the mechanism (example of authentication as DIDs theme with the encrypted material that authentication external member combines
Such as, public key, anonymous bio-identification agreement etc.), service endpoints support the credible interaction with DIDs theme.Entity is by decentralization mark
Know symbol (DIDs) mark, authentication can be carried out by proof (such as digital signature, secret protection bio-identification agreement etc.).
DIDs is directed toward DIDs document.The principle of privacy design is followed, each entity, which can according to need, possesses DIDs as much as possible, with
Respect identity desired by entity, realizes the separation of character and background.
As the demand to decentralization identifier is growing, for being still suitble to the new type URL of Web architecture to produce
Two particular requirements are given birth to, and there are also some extra demands, i.e., more conventional URL (such as based on the URL of HTTP) does not have:
1, existing overwhelming majority URL is all based on DNS name or IP address, these titles or IP address are awarded dependent on concentration
Power carries out registration and final control, and the permission that the URL of new type should not need to concentrate is registered, and is parsed, and updates or revocation mark
Know symbol, it should can create and manage DIDs in the case where no any such permission.
2, DIDs and DIDs document can be passed through with the URL of its ownership of encrypted authentication and associated metadata (including public key)
Authentication is carried out using public/private keys cryptographic technique identical with distributed account book.
Ether mill (Ethereum) is the public block platform chain for having intelligent contract function of an open source, intelligent contract
(Smart contract) is a kind of computer protocol for being intended to propagate, verify or execute in a manner of information-based contract, and intelligence is closed
About allow to carry out credible transaction in no third-party situation, these transaction are traceable and irreversible.
The embodiment of the present invention proposes a kind of decentralization identification code management system based on ether mill block chain, such as Fig. 1
Shown, which includes the decentralization identifier document parsing mould under intelligent contract and block chain on the block chain of ether mill
Block, intelligent contract include that decentralization identifier ownership (owner) contract, rotation of key and management (public keys) are closed
About and decentralization identifier association attributes (attribute) contract.
Decentralization identifier ownership contract is used for by binding ether mill address agreement in decentralization identifier
All sides of decentralization identifier.The private key in ether mill is generated at random by specp256k1 elliptic curve, passes through private
The available public key of key, and ether mill address is then the derivative of public key.In asymmetric encryption techniques, the encryption of information is to use public key
It is encrypted, is decrypted with private key, it is ensured that the safety of information；Digital signature is to generate signature with private key encryption and use public key
Verifying signature is decrypted, it is ensured that the belongingness of digital signature has its non-repudiation, it is assumed that A is disappeared with the public key encryption of B
Breath after B is connected to message, is signed with the public key verifications of A first with the private key signature of A, is disappeared after confirmation with the private key decryption of oneself
Breath.
Specifically, decentralization identifier identifier is subject to the data of the address Tai Fang using Fixed CP " DIDs:idhub "
Format, in the present embodiment, each user subject, which can according to need, possesses DIDs as much as possible, to respect desired by entity
Identity, realizes the separation of character and background, and each decentralization identifier can specify an ether mill address conduct
All sides of decentralization identifier, this all side possess this centralization identifier respective counts in modification intelligence and about three parts
According to unique permission.
Rotation of key and management agreement are for realizing being independently recorded in identifying in intelligent contract with decentralization to user
The rotation and management for according with associated public key, by being sent out by user using the ether mill address of all sides of decentralization identifier
Send ether mill to trade calls intelligent contract-defined interface that intelligent contract is called to realize to ether mill.Public key support hexadecimal string,
The data formats such as base64 character string or pem.
Decentralization identifier document parsing module is for reading the data recorded in intelligent contract and converting data to
The decentralization identifier document read for third party or other users.
Decentralization identifier document is using the json data format that can be read.It include going in decentralization identifier document
Version, decentralization identifier contents, public key json array, the customized server-side of user of centralization identifier standard specification
Point and customization special field information.
Specifically, decentralization identifier document mainly includes following field:
1, the version of Context: "@context " expression decentralization identifier standard specification；
2, Subject: " id " indicates decentralization identifier contents, be defaulted as " DIDs:idhub:
EthereumAddressExample"；
3, PublicKeys: " publicKey " indicates that one is independently recorded in decentralization identifier comprising all users
Public key json array in intelligent contract, for rotation of key and management, third party or other users can pass through this field
Content verification user's signature data.The format of public key json array individual element is exemplified below, and public key format is defaulted as
" publicKeyHex ":
4, ServiceEndpoints: " service " is indicated by user record in intelligent contract " Attribute " field
Data refer in particular to user and carry out required service endpoints when data processing under chain under block.Citing, general format are as follows:
5, customize special field information: user can customize special field and be recorded in decentralization identifier to handle
Customization data in contract.
Wherein, decentralization identifier document parsing module by respectively with decentralization identifier ownership contract, close
Key rotation intelligent contract event corresponding with management agreement and decentralization identifier association attributes contract reads the number of each section
According to.Intelligent contract event is to facilitate tool using EVM log build-in function, and in the interface of DAPP, it can be adjusted in turn
With the readjustment of the event of monitoring.Event can be inherited in intelligent contract, when called upon, can trigger the storage of (emit) parameter to friendship
In easy log (a kind of block chain on special data structure), the address information of these logs and contract, and it is merged into block
In chain, always existed as long as block is accessible.
Identifier association attributes contract be used for store user be independently recorded in intelligent contract with decentralization identifier
Relevant attribute information.Attribute information includes the customized service endpoints information of user and entity attribute information.In application
When, the ether mill that all sides of decentralization identifier can independently send binding specific data is traded into intelligent contract,
Such as service endpoints, entity attribute information data and public key of other data formats etc..
The system further includes ether mill interactive module, and ether mill interactive module connects for providing necessary intelligent contract interaction
Mouthful to realize the interaction of user and the intelligent contract.
Due to the opening of block chain, anyone can inquire public key data associated with decentralization identifier
And provable private key is taken care of by the corresponding entity of all sides of decentralization identifier.Due to the spy of block chain and asymmetric encryption
Property, as long as user guarantees the safety of private key.
It is rotation of key and management that direction, which is currently mainly used, in the embodiment of the present invention, and user can pass through ether mill interaction mould
Block discloses the public key independently used using intelligent contract, and third party service provider website and other users can go to center by inquiry
Change the data in identifier document to verify the authenticity of digital signature of the user under block chain to determine user identity, example
Property, basic process are as follows:
1, all sides of decentralization identifier are defaulted as the ether mill address in decentralization identifier, optionally, use
Family can call all sides of the changeOwner interface change decentralization identifier of intelligent contract；
2, user sends the transaction of ether mill using the ether mill address for all sides for representing decentralization identifier and calls intelligence
The addPublicKey interface of energy contract, intelligent contract can be in " mapping (address=> mapping after calling successfully
(bytes32=> mapping (bytes32=> uint))) be added in public publicKeys " data structure one it is as follows
Data: " publicKeys [identity] [keccak256 (publicKeyType)] [publicKey]=now+
validity；" to indicate this public key within validity time validity period from now on effectively；
3, after recording public key validity period, intelligent contract can also add one and special be named as
The ether mill contract data of " DIDsPublicKeyChanged ", i.e. data format are the ether mill intelligence contract thing of " EVENT "
Part, wherein having recorded the data as in second step in " mapping publicKeys ", and there are also upper one
The block link that " EVENT " occurs；
4, it according to the characteristic in ether mill, searches " EVENT " and conveniently and in " EVENT " also remembers than the data structure in contract
The block link that upper one " EVENT " of record occurs, decentralization identifier document parsing module search area according to this principle
Data and the identity data of specific decentralization identifier is verified out in block chain, and generates decentralization identifier document；
5, other users or third party can wish the open public affairs used by decentralization identifier document acquisition user
Key verifies the digital signature information of user, also or can pass through and to call ether mill intelligence contract " validPublicKey
Whether (address identity, bytes32publicKeyType, bytes32publicKey) " interface check client public key
It is proper use of.
The present invention is based on the intelligent contracts of ether mill block chain to realize rotation of key management function, and uses for reference ether mill and made
Cryptography specification specifies the form of expression of decentralization identifier, and encodes and realize the parsing of distributing attribute of identifiers
Function, entity can freely use any shared root of trust, by and the combination of ether mill block chain provide a kind of management
The method of root of trust made any entity can be in any number of independent letter both without concentrating permission or without Single Point of Faliure
Appoint the decentralization identifier for creating and managing oneself on root.The final following principle for realizing DIDs framework:
Fraction: eliminating to the concentration permission of identifier management or the requirement of Single Point of Faliure, including globally unique identifier, public
Authentication secret altogether, the registration of service endpoints and other metadata；Autonomy: provided for the mankind and non-human entities directly possess and
The ability for controlling its numeric identifier, without relying on external permission；Privacy: enough privacies for controlling its information, packet are allowed entities to
Include attribute or the minimum of other data, selectivity and progressive disclosure；Safety: provide enough safeties for relying party, with according to
DIDs document is relied to reach required guarantee rank；Evidence-based: enough encryption certificates that authentication is provided and authorization are allowed entities to
Permission proves；Can find: allow entities to enough DIDs for finding other entities, with understand more information in relation to these entities or with
These entities interact；Intercommunity: using the standard of interoperable, having can use as interoperability and designs existing
