The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.As long as in addition, technical characteristic involved in the various embodiments of the present invention described below that
Not constituting conflict between this can be combined with each other.The present invention is described in more detail With reference to embodiment.
As shown in figure 3, a kind of anonymous login method based on block chain is provided in the embodiment of technical solution of the present invention,
It is mainly characterized by, and user passes through authorization server first and carries out verifying authorization, then breathes out to personal attribute information
Uncommon operation, generates specific cryptographic Hash, and will be in corresponding information preservation to block chain.User need login system (or
Say it is third party system) when, it is only necessary to the cryptographic Hash of part attribute information and part attribute information is provided, by being stored in
Verification information on block chain can verify the identity of user, to realize that the anonymity of user logs in.
It should be strongly noted that the anonymity in the present embodiment logs in, it is not the simple name that conceals, but to user
Identity carry out part covering encryption, only need to provide partial user attributes information when being logged in, so that passing through use
The part identity information that family provides, which can determine if to meet, logs in condition.To the part identity information provided according to user
It can only determine certain crowd's range, can not actually determine specific user identity.That is, by that will request to log in
User is hidden in the crowd for meeting certain condition range, to achieve the purpose that anonymity.
Specifically, it as shown in Figure 1, in the present embodiment, first has to according to security parameter and rivest, shamir, adelman etc., it is right
The public key and private key of authorization server are initialized, and the public key of the authorization server is disclosed, and according to the public key acquisition pair
The block chain address ADR answered.Authorization server by initialization generates several random numbers at random, and is randomly assigned to use
Family.In the present embodiment, random number is preferably expressed as { Rand0,Rand1,......,Randm-1,Randm}。
Further, user enumerates all properties information of itself, such as name, date of birth, gender, state
Nationality ..., to obtain the set { attr of user's all properties0,attr1,.......,attrn-1,attrn, according to user
Attribute set calculate obtain Merkle RootMerkle Root in the present embodiment is as shown in Figure 2.
Merkle Root for arbitrary user, in the present embodiment(identification parameters of user) preferably have such as
Lower calculation formula:
Specifically it is exactly to carry out Hash operation by whole attribute informations to the user, finally obtains a representative
The Merkle Root (cryptographic Hash) of user identity.Its principle is, is carried out continuously Hash operation to adjacent attribute, and incite somebody to action
To result be iterated Hash operation.Because any character string carries out continuous Hash operation, (breathing out for identical cryptographic Hash is obtained
Uncommon collision) probability is minimum, so that the cryptographic Hash of attribute can be used as the proof of identity mark of this user.
Above scheme is illustrated by taking Fig. 2 as an example, it is assumed that according to the name of user, date of birth, gender and nationality
This several attribute informations can confirm the identity of user, then these attribute informations are divided into two groups, be iterated Hash respectively
Operation, until obtaining last Merkle Root.As being that will represent the attr of name in Fig. 20With represent the date of birth
attr1Hash operation is carried out, Hash (attr is obtained0, attr1), it is similar, obtain gender attribute information and nationality's attribute information
Hash (attr2, attr3), then again to Hash (attr0, attr1) and Hash (attr2, attr3) Hash operation is carried out,
Cryptographic Hash obtained is the Merkle Root in Fig. 2.
Due to carrying out Hash operation for any character string, (Hash collision) probability for obtaining identical cryptographic Hash is minimum,
To which this Merkle Root can be used as the identification voucher of user.Preferably, to each attribute information in the present embodiment
Hash operation is all carried out, i.e., for user i, the cryptographic Hash of j-th of attribute information has following expression:
hashij=Hash (attrij)。
Further, in Fig. 2 on the basis of Merkle Tree, selection parameter generates to one's name user as requested
Checking parameter, checking parameter (the commitment ω in the present embodimenti) there is following expression:
Wherein G is ZpOn q rank subgroup, select random generator G=< g0>=...<gj>, h g0 a, r is random number,
Aux is arbitrary number, is used to replace logon authentication code in the future.Parameter a is privacy parameters, is only in the possession of the user, other parameters are
Open parameter.
Then, the random number and checking parameter that Merkle Root, distribution obtain are sent collectively to authorization service by user
Device.Authorization server reads the random number of user's offer first, judges whether the random number in authorization server is distributed to user
List of random numbers in, if, to user provide data be further processed after be sent in block chain, otherwise
Refuse the authorization requests of the user.
Meet the user of determination requirement for random number, authorization server carries out signature processing to it first, then again into
Row is sent, and detailed process is as follows:
Transaction=GenTran (version, input, output, data:userdata+signature)
After block chain node confirmation of the above-mentioned data parameters by certain data by permanent cured into block chain, anyone
It can not all modify to the above-mentioned authentication information of the user, i.e. user's binding procedure for completing self attributes information.
One as the present embodiment is preferred, in order to increase anonymity controlled and independent, can choose and above-mentioned step is performed a plurality of times
Suddenly, i.e., signature processing repeatedly is carried out to the identification parameters and checking parameter that obtain according to customer attribute information, and is solidified guarantor
It is stored in block chain.In other words, the technical solution in the present embodiment allows a user using more set cryptographic Hash (such as to identical
Attribute information use different hash algorithms to obtain different cryptographic Hash etc.) carry out authentication, wherein each cryptographic Hash
Can be different, but all it is the accurate true identity parameter of the user.
Simultaneously it is emphasized that during above scheme is implemented, user's continuous use repeatedly it is identical it is anonymous with
Card may result in user anonymity mechanism forfeiture, more specifically, if the same user uses same class anonymous credentials (such as
The only display age) same system connection is logged in repeatedly, which counter may release, this same class anonymous credentials belongs to together
One user allows a user to exist to preferably realize the anti-traceability and anticorrelation of login system in the present embodiment
It is authenticated on different authorization servers, and using there is hideing for different authorization server endorsement under different log on request
Name voucher.
Herein technically, user can start to carry out anonymous access to third party system, and detailed process is as follows:
Firstly, third party system issues actual business demand, that indicates system logs in condition, such as only allows some group
Personnel log in, or the personnel of certain age bracket is not allowed to log in, can freely set according to demand.Namely
Say, can be logged in for user and certain threshold condition is set, can be user single attribute information (such as age, gender or
Person nationality), it is also possible to the combination (such as age+gender) of multiple attribute informations, this is not made in technical solution of the present invention specific
Restriction, also technical solution of the present invention is used the specific object classification in the present embodiment for illustrative purposes only, is not intended as to skill of the present invention
The concrete restriction of art scheme.
Then, actual demand of the user according to third party system, the generation login credential of attribute information required for selecting, so
The login credential is supplied to third party system afterwards.In the present embodiment, attribute information login credential is preferably as follows:
Wherein, authcode is logon authentication code, it should be noted that hashijAnd τijFor attribute attrjVerifying ginseng
Number, τ hereinijIt is calculated as the algorithm of the Merkle proof of standard, τijCalculation formula is preferably as follows,
Wherein, ΓiCalculating use Susan Pedersen and promise to undertake algorithm because only user knows the parameter a of privacy and discrete
The decomposition problem of logarithm, therefore only user can calculate rapidly Γi, calculation formula is preferably as follows:
hrg0 aux=hrg0 authcode
g0 arg0 aux=g0 ar′g0 authcode
It in other words, include following information in above-mentioned login credential: attribute information, the corresponding Hash of the attribute information
The identification parameters of value, the certificate parameter of the attribute information, the checking parameter of user and user, third party is according to above- mentioned information pair
The identity of user is verified.
In the present embodiment, the verification process of third party system is preferably as follows:
Third party's resource system according to the information scanning block chain in login credential, obtains firstAnd ωi, comparing it is
No consistent in login credential, inconsistent then directly refuses log on request, unanimously then enters next step.Then right
hashijIt is verified, i.e. verifying hashij=Hash (attrij) whether true, continue if setting up to τijWithIt is verified,
Further to (ωi, Γi) verified, any one is unsatisfactory for, and refuses user and logs in, only above-mentioned in login credential
Parameter information is verified, and is just allowed the user of current request to carry out anonymity and is logged in.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
