Description

A kind of device, system and method for realizing authentication

The application is to be that October 23, application number in 2008 are 200810224837.9 the applying date, and denomination of invention is divided an application for the application of " a kind of device, system and method for realizing authentication ".

Technical field

The present invention relates to authentication techniques, particularly a kind of device, system and method for realizing authentication.

Background technology

At present, along with the develop rapidly of Internet technology, during online transaction had been deep into daily life and has worked, wherein, " Web bank " was the most representative application with the application of " ecommerce ".For instance, " Web bank " submits channel to as a kind of brand-new bank client service, no matter the client stays at home, office, still can handle various bankings such as comprise inquiry, transfer accounts, pay the fees on the road by the internet, manages the assets of oneself.

But Internet technology is bringing people simultaneously greatly easily, the safety issue of internet displays with also becoming increasingly conspicuous, for example, for Web bank, when the client concludes the business by the internet, data such as client's user identification code (for example account number) and password are very easily victim interception or steal in process of exchange, the assailant utilizes user identification code and the password tackling or steal to carry out illegal operation, client's interests have directly been encroached on, this not only directly has influence on the prestige of online transaction, also the online transaction development is produced disadvantageous negative effect.

In order to strengthen the fail safe of internet message transmission, need set up the security system of internet message transmission, can only there be the people of corresponding authority to visit to guarantee the data in the internet system; Simultaneously, also need to provide certain Authentication mechanism, client's the user identity that guarantees to be stored in the internet system is consistent with the identity that the client declared of internet usage network system, has only the user by authentication, could access system resources and operate.Therefore, for the internet, the authentication management is the basis of whole information security system, if do not have effective identity verification management means, method and measure, the client identity authentication of access internet network system just is easy to victim and forges, and causes the assailant to be entered the safety precaution system.For example, domestic in recent years " fake site " and the main cause of the stolen case of clients fund that repeatedly takes place is exactly because client's user identity is stolen.

Several authentication techniques that prior art is set up the security system of internet message transmission are described below, mainly comprise:

One, dynamic password ID authentication

The dynamic password ID authentication technology is also referred to as " one-time pad " technology, and promptly the each password that uses of user all waits dynamically according to time or access times and produces, and each password can only use once.

Subscriber equipment can use proprietary token to produce dynamic password, and the user only need be with the current password input that shows on the token in use, and the certificate server end adopts the identical current valid password of algorithm computation can realize the affirmation of identity.

Specifically, the principle of dynamic password ID authentication is, the each password that uses of user is produced by proprietary token, and each password that uses is all inequality, because password uses once the back just to lose efficacy, thereby, even the assailant intercepts and captures this password, the certificate server end also can't use the counterfeit validated user identity of this password, so as long as just can think that by password authentification this user's identity is reliable.By adopting the method for one-time pad, the dynamic password ID authentication technology has guaranteed the fail safe of user identity effectively, and compare with the follow-up IC-card authentication of mentioning, USB Key authentication, biological characteristic authentication, cost is lower, and present dynamic password mode adopts hardware mode mostly, based on the token of time synchronized or incident.

Though the dynamic password ID authentication technology is easy to use, its fail safe is unsatisfactory.For example, when meeting with virus or assailant's attack, if the user imports dynamic password and transmits by network, the assailant who is positioned between subscriber equipment and certificate server communication port just can monitor or internal memory reads etc. and to attack after mode be intercepted and captured dynamic password by keyboard, can make the user can't finish login, and cause the network connection to disconnect, connect illusions such as overtime; The assailant can also utilize the dynamic password fake user of intercepting and capturing to sign in to certificate server on the other hand, carries out illegal operation, and the user is sustained a loss.

Two, USB (USB, Universal Serial Bus) Key digital certificate authentication

The authentication of USB Key digital certificate is carried out authentication by USB interface-based USB key hardware device, is a kind of identity identifying technology that grew up in recent years.USB Key adopts built-in single-chip microcomputer or intelligent card chip, and the storage user is based on the digital certificate of PKIX (PKI, Public Key Infrastructure) framework.This digital certificate is one group of data structure that comprises subscriber identity information (key) being issued by third party trusty certification authority, and the PKI framework has made up identity and data security that a cover perfect flow process guarantees the holder of digital certificate by adopting cryptographic algorithm.Specifically, the principle of digital certificate authentication is: transmit leg produces passage information and this section Word message is carried out unidirectional irreversible conversion, then, transmit leg is encrypted the text transform that carries out unidirectional irreversible conversion generation with the privacy key of oneself again, and with the original character information that produces and the text transform result after encrypting send the recipient of appointment to, this section just is called digital signature through the text transform result after encrypting.The recipient receives the text transform result after original character information and the encryption, the original character information that receives is carried out the irreversible conversion of same individual event, the public-key cryptography that utilizes transmit leg simultaneously is decrypted the text transform result of the encryption that receives, if the irreversible text transform result of individual event that text transform result and recipient after the deciphering carry out self is consistent, then the recipient thinks that transmit leg has passed through authentication, can believe the other side's identity.

Yet, the digital certificate of USB Key digital certificate authentication itself also is a kind of digital identity, still exist by the danger of bootlegging, so, prior USB Key has increased a lot of self-destruction measures as the digital certificate store medium, to guarantee the destroying digital certificate of being stored automatically when being cracked; And, strengthened some safety measures of PKI frame system, make USB Key can guarantee that customer digital certificate can't be replicated.

But,, and need cause customer using cost higher at subscriber equipment for each user disposes a USB KEY owing to the cost at the CA center of disposing and safeguarding the authentication of USB Key digital certificate is very huge; In addition, all need when using USB KEY is inserted in the USB interface of subscriber equipment, if subscriber equipment does not have USB interface or USB interface is damaged or USB KEY damages, the user can't visit the CA center at every turn; And, no matter be signing messages, or digital certificate, when in network, transmitting, still can't stop the man-in-the-middle attack in the authentication each time.

Existing a kind of the improving one's methods that proposes is that the communication link channel is encrypted; as socket layer (SSL safe in utilization; Security Socket Layer) protocol protection; can stop network interception signing messages or digital certificate, but this encryption channel still can't stop the connection hijack attack in the authentication each time.For instance, when browser points to https: //when xxx.com connected, digital certificate can exchange during SSL shakes hands, and the PKI of preserving in the digital certificate is used to the encryption of session.If the user does not have the PKI at CA center during connection, browser will point out the user to accept or refuse this digital certificate, and for the certificate of a large amount of websites distribution, the PKI that the user does not have a respective site is checked the legitimacy of certificate, thereby, for common interactive CLIENT PROGRAM, for example, browser may cause SSL to be connected lose meaning, is really or oneself has suffered the connection hijack attack thereby make the user can't differentiate the information that website uses unknown CA center; Further, even the user once browsed this website in the past and preserved its digital certificate, also still may succeed by victim; In addition, because present attack technology can be broken through ssl protocol at an easy rate, so, in authentication, still can suffer the attack that similar connection is kidnapped even the user can check the legitimacy of website digital certificate.

Three, biometric identity authentication

The biometric identity authentication is based on the unique biological characteristic of user, and for example, fingerprint recognition, iris recognition wait the technology of identifying user identity.Because its direct end user's physical features is represented everyone digital identity, different people has the possibility of identical biological characteristic and can ignore, and therefore, in theory, the biometric identity authentication is reliable identity authentication mode.But the authentication of prior biological feature based on the influence of biometrics identification technology maturity, also has bigger limitation.At first, the accuracy of living things feature recognition and stability are still waiting to improve, if particularly user's body is subjected to the influence of sick and wounded or spot, often causes and can't normally discern, the situation that causes validated user to land; Secondly, because research and development drop into big and output is less, the cost of biological characteristic authentication system is very high, only is suitable for the very high occasion of some security requirements at present, as uses such as armies, also can't accomplish the large tracts of land popularization; In addition, if carry out authentication, then can't stop replay attack, man-in-the-middle attack etc. at the transmission over networks biological information.Replay attack, the information that is about to intercept and capture resends to authentication server and authenticates, thus the attack of obtaining accesses identity; Go-between (MITM, Man-in-the-Middle Attack) attacks, the invasion that is a kind of " indirectly " is attacked, this attack mode is to be placed between two communication computers of network in connecting by the computer virtual that various technological means will be controlled by the invador, and this computer just is called " go-between ".The invador is one of this computer simulation or two primitive compuers then, " go-between " can set up be flexibly connected with primitive compuer and allow it to read or revise the information of transmission, yet two primitive compuer users think that but they are in mutual communication.Usually, the process of this " data interception---is revised data---and sent data " just is called as " Session Hijack " (Session Hijack).

Four, integrated circuit (IC, Integrate Circuit) card authentication

What IC-card authentication was based on IC-card hardware can not guarantee that user identity can be by counterfeit technology by duplication characteristic.The IC-card built-in integrated circuit has the data relevant with user identity in the card, by special device fabrication, can think not reproducible hardware by special manufacturer.IC-card is carried by validated user, during login IC-card is inserted special-purpose card reader and reads wherein information, with checking user's identity.Because the data that read from IC-card are static at every turn, than the authentication information that is easier to be truncated to the user, therefore there is bigger potential safety hazard by technology such as internal memory scanning or network monitorings in the assailant.

By as seen above-mentioned, existing identity identifying method commonly used, the authentication fail safe is lower, has damaged the interests of validated user, in addition, also has following defective:

(1), identity identifying technology is realized complicated.As the authentication of USB KEY digital certificate;

(2), cost is higher.As the authentication of USB KEY digital certificate, biometric identity authentication;

(3), safeguard complexity.As USB KEY digital certificate authentication;

(4), suitable scene is limited, convenience is poor.As biological characteristic authentication, the authentication of USB KEY digital certificate.

In this step, the Certificate Authority executor receives access request, the customer equipment identification that can comprise according to access request, determine the authentication strategy to this subscriber equipment, the authentication strategy can be that subscriber equipment sets in advance in the Certificate Authority executor, for example, it is 1 that common identity identifier is set, the tolerance authentication is designated 2, and being with outer identity identifier is 3, identifies high authentication and comprises simultaneously identifying low authentication.For instance, if the authentication strategy that subscriber equipment sets in advance is designated 3, represent that then subscriber equipment need carry out common authentication, tolerance authentication and the outer authentication of band successively; Also can be that the authentication strategy is arranged in the authentication policy module, be the necessary flow process of carrying out and give tacit consent to common authentication, after common authentication is passed through, inquire about authentication strategy in the authentication policy module by the Certificate Authority executor, whether also need to carry out tolerance authentication or outer authentication of band or tolerance authentication and be with outer authentication thereby obtain.

In the present embodiment, need carry out common authentication, tolerance authentication and the outer authentication of band successively to subscriber equipment.

The Certificate Authority executor receives access request, after determining subscriber equipment authentication strategy sign, send common ID authentication request to common authentication server, receive the common authentication that common authentication server returns and require information, send the access request response message to subscriber equipment, carry self authenticating identity information, self authenticating identity information digital signature information that can be the Certificate Authority executor generate with self private key.

In the practical application, the identity identifying technology that the Certificate Authority executor supports according to the different application and the subscriber equipment of subscriber equipment, can adopt the authentication of corresponding dynamic password, the authentication of USB Key digital certificate, biometric identity authentication or IC-card authentication mode, send corresponding authenticating identity information to subscriber equipment.

Step 203, subscriber equipment receives the access request response message, and authentication verification mandate executor's authenticating identity information is passed through as checking, returns common authentication requirement response message to authentication verification mandate executor;

In this step, subscriber equipment receives the access request response message, authenticating identity information according to Certificate Authority executor transmission, adopt corresponding authentication mode, for example, the Certificate Authority executor adopts dynamic password ID authentication to send authenticating identity information, and then subscriber equipment adopts corresponding dynamic password ID authentication technical identification Certificate Authority executor's authenticating identity information, checking flow process and existing procedure are similar, do not repeat them here.

If subscriber equipment is by the authenticating identity Information Authentication to the Certificate Authority executor, think that then this Certificate Authority executor is trusty, subscriber equipment is handled self authenticating identity information, as password, signing messages, biological characteristic etc., and the authenticating identity information of handling is carried at common authentication requires in the response message; Otherwise, return the common authentication of carrying authentification failure to the Certificate Authority executor and require response message.

Step 204, the Certificate Authority executor receives common identity and requires response message, and the subscriber equipment authenticating identity information that will comprise sends to common authentication server;

Step 205, common authentication server receive subscriber equipment authenticating identity information, carry out authentication, return subscriber equipment authenticating identity response message to the Certificate Authority executor;

In this step, common authentication server receives subscriber equipment authenticating identity information, and the flow process and the existing flow for authenticating ID of carrying out authentication are similar, do not repeat them here.

If authentication is passed through, then in the subscriber equipment authenticating identity response message of returning, carry the authenticating identity successful information, otherwise, in the subscriber equipment authenticating identity response message of returning, carry the authenticating identity failure information, the authentication request of refusing user's equipment.

Step 206, the Certificate Authority executor receives subscriber equipment authenticating identity response message, and the authentication that determines one's identity is passed through, and sends tolerance authentication request information;

In this step,, in present embodiment, need successively subscriber equipment to be measured authentication and the outer authentication of band again, send tolerance authentication request information to subscriber equipment tolerance engine if the Certificate Authority executor has determined subscriber equipment authentication strategy sign.

If user's authentication policy store in the authentication policy module, then sends tolerance authentication challenge solicited message, execution in step 206a～step 206b (not shown) to the authentication policy module.

Step 206a, the authentication policy module receives tolerance authentication challenge solicited message, and the authentication strategy of inquiry storage returns tolerance authentication challenge request response message to the Certificate Authority executor;

In this step, the authentication policy module receives tolerance authentication challenge solicited message, the authentication strategy that obtains according to inquiry, determine whether to need to carry out further authentication, as not needing, return tolerance authentication challenge request response message to the Certificate Authority executor, notifying user equipment can enter operation system; If desired, return tolerance authentication challenge request response message to the Certificate Authority executor, indication Certificate Authority executor carries out follow-up authentication.

In the practical application, if the authentication policy module inquires the user need carry out the outer authentication of tolerance authentication and band the time, can be that subscriber equipment authentication strategy sign is carried in the tolerance authentication challenge request response message, in follow-up when tolerance authentication is passed through, no longer authentication query requests information outside the authentication policy module sends band is with outer authentication but directly carry out; Certainly, in the practical application, also can be that authentication query requests information outside the authentication policy module sends band is obtained the information whether user needs to carry out the outer authentication of band again when follow-up vacuum metrics authentication is passed through.

Step 206b, the authentication policy module receives tolerance authentication challenge request response message, determines to measure authentication, sends tolerance authentication request information;

In this step, do not need reauthentication information if comprise in the tolerance authentication challenge request response message that receives, notifying user equipment can enter operation system; Otherwise,,, send tolerance authentication request information to subscriber equipment tolerance engine as subscriber equipment authentication strategy sign according to the indication information that comprises in the tolerance authentication challenge request response message.
