To explain the present invention, it is not intended to limit the present invention, can realizes that the product of said function belongs to equivalent and improvement, includes
Within protection scope of the present invention.Specific method is as follows：
Embodiment one：As shown in Figure 1：In practice, base station poll exchange system receive block chain user the band of position and
Identity information；The area that block chain ID according to being carried in the band of position and identity information has been stored from base station stored system
In the authentication information of block chain user high in the clouds, go to inquire about the block chain ID correspondence high in the clouds authentication information of block chain user；
High in the clouds authentication module collects all of block chain user high in the clouds authentication information under each region；According under each region
All of block chain user high in the clouds authentication information generation block chain user high in the clouds authentication information, be used to reduce certification it is concurrent when meter
Calculation amount, and memory block chain user high in the clouds authentication information is to high in the clouds authentication module；The band of position block chain user that will be inquired
High in the clouds authentication information is sent to block chain user；
Wherein, the band of position of all of block chain user and identity information under each region is collected to be specially：Take turns base station

It is required that；
Authentication module sends authentication acquisition request to its local block chain user is in；Authentication mould
Block chain user under block directly returns to the band of position and the high in the clouds certification letter of oneself by transport module to high in the clouds authentication module
Breath；And in return information, added according to the high in the clouds authentication module module and marked, prevent both sides from denying, and the block for returning
Chain user is added to the node in network, while block chain user is needed first from base station stored system downloads portion copy to client
In client database, authentication is then proceeded by again.
Base station stored system memory locations region and high in the clouds authentication information include：By the band of position and high in the clouds authentication information with
Many helical structures are stored；Wherein, many helical structures include：Single linked list, and each are formed with the row that are designated of the band of position
Area identification is associated as well to a circular linked list, and circular linked list includes the high in the clouds authentication information for belonging to block chain user, so that shape
Into complete block chain.
Authentication starts to produce key pair by ECDSA, obtains private key:Public key is calculated with private key,
And calculate PIN with by public key；Private key is carried out into ECDSA random hash and draws public key, with this
Simultaneously, it is impossible to allow public key to calculate private key, PIN is calculated by public key, it is provided as bit coin address.Public key is carried out
SHA256 Hash calculations；Identity request information is signed with private key.
Verification process is divided into request authentication module and high in the clouds authentication module two parts, asks authentication module to be recognized to high in the clouds first
Card module initiates connection request.High in the clouds authentication module may require that request authentication module sends over the identity information of oneself.It is real
In border as shown in Figure 1.Key is produced:Key pair is produced using ECDSA algorithms；By key to producing private key；Private key is by ECDSA
Calculate and produce public key K2, and encryption is put into identity chain, identity chain is the different block chain user of high in the clouds authentication module generation
The block that authentication information is formed, referred to as identity chain；Obtain adding the PIN of timestamp by Hash calculation by K2,
Then it is encoded with bases64；Submit application request to:Including authentication voucher and digital signature.Using private key pair
Request is signed, and this signature is mark head.With public key encryption authentication voucher, will be asked with identifying head type
Information is transmitted by private network, wherein the generation process of mark head is as follows.Produce a unique random number；By random number plus
Enter in request；High in the clouds authentication module receive request authentication module ID authentication request after, first by public key from identity chain
In separate, verify signature validity.Authentication failed message is not returned to if if certification, authentication terminates；Then
Verify the validity of PIN.PIN include timestamp and verification and.Authentication failed message is returned to, identity is recognized
Card terminates；If being verified, the request authentication module can return to a message acknowledgment being verified, while the request
The digital signature information of oneself can be sent to A by authentication module with the identity of request end, and flow is consistent with shown in Fig. 1；And according to
The principle as in chain transaction is added to bit coin block, this certification summary, including block chain authenticating user identification is broadcasted
This authentication can be added high in the clouds by the random number of the summary of voucher, random number and last authentication, nodes
In block, and then it is added in the high in the clouds in network.A is received after the authentication information that B sends according to authentication in practice
The order of the first step is verified to the identity of B, if being verified, can also return to a message acknowledgment being verified, then
This checking is broadcasted, can be also added to the block chain user name of B in the block of high in the clouds by nodes.If certification node is first
Secondary addition network, then need to the authentication high in the clouds safeguarded in network other nodes request download P2P networks to node sheet
Ground.Even if above procedure communicating pair has the side can also not carry out online, it is only necessary to communicate an other side when reaching the standard grade to please
Authenticating party is asked to be authenticated, this mode agrees with P2P network environment needs.The strick precaution of network attack refers to recognizing in identity
Attacker can intercept the data of certification both sides during card, the purpose to reach fraud system transparent to certification both sides.Bit body
Part certification prevents Replay Attack using the high in the clouds authentication module mechanism, can all be wrapped in the certification message that authentication authorization and accounting both sides send
The high in the clouds authentication module at close enough current time is included, and the high in the clouds authentication module of attacker will be relatively distant from
Current time.Man-in-the-middle attack in authentication refer in the middle of attacker certification both sides with the authenticating party at two ends and be certified
Side is authenticated respectively so that authenticating party and the side of being certified will not perceive the attacker of centre.In the present invention, password is will not
Transmit in any form in a network, so as to cannot be intercepted and captured by the 3rd people.If illegal node is wanted to pretend to be the side of being certified to come
Authentication is completed, it is necessary to change the content in the block of high in the clouds, and complete the whole of all blocks after this block again
Workload, this is a huge test for the computing capability of computer, is hardly possible realization in reality.Due to
Introduce high in the clouds mechanism, in network all nodes all can participation certificates authentication procedures each time, prevent from distorting using chain transaction
The proof of work mechanism of transaction record, that high in the clouds most long is safeguarded in a network come reach prevent certification from denying, distort, it is false
The behavior such as emit.The transaction of bit coin is no doubt reliable, but when being applied in authentication, also has some to ask in theory
Topic needs overcome and solve.First, before one-time identity authentication terminates, certification both sides all can by certification summary-advertisement to the whole network,
The problem for being so possible to broadcast storm occur when multiple nodes concurrently carry out authentication.On this problem, bit
Coin designer is exactly the size for reducing block for the solution that big the brought Denial of Service attack of trading volume is proposed
By block size from original without the upper limit, it is changed into having the upper limit, it means that the trading processing ability of bit coin only about per second 7
Pen, but the frequency of authentication should be higher with bit coin trading frequency in network, then in authentication, control
While authentication processed concurrent quantity, it should improve the threshold value of authentication per second, so as in controlling network
Broadcasting amount, reduces while broadcast causes excessive influence on network and also can guarantee that concurrent authentication quantity disclosure satisfy that network area
The demand of block chain user.Bit identity verification scheme is a kind of side for being directly compatible with block chain user name or Email and password
Case.In the present invention, when private key is stored, we are encrypted to prevent unexpected attack or threat using password.Bit identity
The most special place of authentication method is that password can be transmitted in a network by any way in no instance.Using this
Mechanism, block chain user still can be verified using block chain username and password, but be decrypted using password locally
Private key, is then gone to sign ID authentication request with private key.Key is produced to for authentication number based on ECDSA algorithms
Word is signed, and before authentication starts, the node being added in network needs first to download a high in the clouds copy to local data
In storehouse, authentication is then proceeded by again.The basic procedure of bit authentication is described, then to present system characteristic
Analyzed.Trust in invention in addition refers to that will not be led to by malefactor using certain technological means protection network platform
Crossing direct physical access means carries out malicious operation.Ensure that the credible most straightforward approach of the network platform is to login system
Block chain user carry out authentication, communicating pair needs the both sides to carry out two-way authentication before being communicated in the P2P networks.
The present invention carries out logic analysis carrying out formalized description to authentication to its security, finally calculates authentication
Confidence level, algorithm and step in this confidence level computing system is given below.Access entity refers to the object of certification request,
Only certification is by just allowing and accessed object communication.Service Ticket is used before referring to access entity and accessed object communication
To prove the digital evidence of oneself identity.Authentication mechanism refers to the methods that Service Ticket is produced and verified:High in the clouds certification
Module refers to the functional unit of administrative authentication voucher.Authentication module refers to the functional unit of authentication verification voucher.Body
Part relying party refers to the functional unit that its behavior operation depends on authentication module result, it may be possible to authorized component.
Authentication domain refers to an authentication part in same administration authority border.Authentication mechanism, high in the clouds
Authentication module, authentication module and access entity because its in the presence of uncertainty may influence whether identity authentication result can
Reliability.The uncertainty of wherein authentication mechanism shows as certification authority may be cracked, and such as some AESs are cracked, this
Certification authority will be caused compromised；The uncertainty of high in the clouds authentication module shows the tightness of management aspect, and management is not
The problems such as certainty may result in that Service Ticket is compromised, be forged；The uncertainty of authentication module is mainly manifested in
Whether information system and authentication protocol safe and reliable, this will cause Service Ticket be stolen leakage or be forged；Access entity
Uncertainty refers to that visitor is not necessarily reliable, the storage of certification authority whether safety etc., this will cause certification authority to be stolen to let out
Reveal, attacked or be held as a hostage.Various uncertain factors in identity-based verification process, by the element of trust of authentication point
It is following 3 class:Ensure that Service Ticket is not compromised, be denoted as 1 class.Ensure that Service Ticket is not forged, be denoted as 2 classes.Ensure certification
Voucher is not held as a hostage, and is denoted as 3 classes.The insincere factor is which kind of uncertain factor causes to recognize in key object in authentication procedures
The influence degree of the generations such as compromised voucher, forgery or abduction is demonstrate,proved, NOCONFIDENCE, the insincere factor of key object is denoted as
Can represent that wherein x represents the insincere factor of 1 class of object with NOCONFIDENCE ()=(x, y, z), Y represents the 2 of object
The insincere factor of class, z represents the insincere factor of 3 classes.But comprehensive several significant uncertain factors, analysis assumes theirs
Uncertainty, then calculates the trust value of authentication, can judge high in the clouds authentication with degree of safety, confidence level substantially
Confidence level.Degree of safety refers to the possibility that key object ensures that certification authority is not compromised, is not forged or is not held as a hostage, uses
Probability is represented.Confidence level is the method trusted for quantificational expression.In authentication mode, can in fixed authentication domain
To represent the security of authentication mode by the degree of belief between computing system entity, equally represented with probability.Confidence level point
It is Service Ticket confidence level, authentication secret confidence level, digital entities confidence level, physical entity confidence level.But due to high in the clouds and visitor
Communication between the end of family is influenceed by many uncertain factors, causes the result of authentication service not absolute confidence.
Embodiment two, as shown in Figure 1：In practice by from can with the authentication based on dynamic password and public-key cryptosystem
Reliability Analysis are calculated and authentication Analysis on confidence of the present invention based on high in the clouds is calculated, and both result of calculations are compared
Compared with advantage of the analysis present invention in terms of confidence level.Step is：Setting authentication mechanism, Service Ticket is by body after public key and encryption
Part mark and block chain user password composition；Dynamic password is randomly generated；By the block chain user password for comparing storage；High in the clouds
Authentication module:Distribution block chain ID is to access entity；Authentication module:The public key distributed using elliptic curve systems
Private key carries out key authentication, so authentication-access entity legitimacy；Request authentication module:Using public key encryption identity.
Authentication mechanism:Service Ticket is made up of identity after public key and encryption and block chain user password；Digital signature keys are by ECC
Algorithm is produced；By verifying digital signature validity and the whole network node participation certificates；High in the clouds authentication module:Identity information is not
It is single to be present in certain authentication server database, but all node local datas in being present in network in the form of the high in the clouds
Storehouse, and store be authentication voucher summary, useful identity information can't be revealed；Authentication module:Each
Node can serve as authentication module, is authenticated using digital signature authentication method；Request authentication module:Key by
ECDSA algorithms are produced, and private key is preserved by requests verification side with password encryption, needs to be decrypted with password during using private key signature.It is logical
Cross the confidence level result that uncertain factor system degree of belief computational methods utilized above draw to show, uncertain factor includes identity
Certain uncertain factor causes compromised Service Ticket, forgery or abduction etc., present system in key object in verification process
Authentication Reliability ratio now the existing authentication based on dynamic password and elliptic curve it is with a high credibility, also thus demonstrate,prove
