Two-dimensional code authentication system based on quantum communication network
Technical Field
The invention relates to the field of network security communication, in particular to a two-dimensional code authentication system based on a quantum communication network.
Background
In identity authentication, static passwords are easily stolen by malicious software or are violently cracked because the static passwords are fixed and unchanged. In order to solve the security problem of static passwords, the dynamic token technology has been the way.
The dynamic token replaces the traditional static password with a one-time password generated based on three variables of time, event and key. Each dynamic token card has a unique key, the keys are simultaneously stored in a server side, and the dynamic token card and the server respectively calculate the dynamic token to be authenticated according to the same key, the same random parameters (time and event) and the same algorithm during each authentication, so that the consistency of passwords is ensured on two sides, and the identity authentication is realized. Because the random parameters in each authentication are different, the dynamic tokens generated in each authentication are also different, and the randomness of the parameters ensures the unpredictability of each password, thereby ensuring the safety of the system in the most basic and important password authentication link. The dynamic token is classified from the terminal to include a hardware token and a handset token. The mobile phone token is client software installed on the mobile phone and used for generating the dynamic token.
International dynamic tokens have 2 major algorithms, one is the SecurID (using AES symmetric algorithm) of RSA and one is the HMAC algorithm used by the OATH organization. The dynamic token algorithm used domestically uses national secrets SM1 and SM 3.
Two-dimensional codes, also known as quickresponsecodes, are a very popular encoding method in recent years. Compared with the traditional bar code, the bar code can store more information and represent more data types. After the two-dimensional code is swept a yard payment function and is used the habit and train through what believe a little and pay precious sweeping a yard payment function, has had extensive cognitive degree. At present, the two-dimensional code of each large platform application is generated by a background, and an application terminal user uses a mobile terminal APP to scan the two-dimensional code to perform safe identity authentication. Two-dimensional code technology may be combined with dynamic token technology, for example to carry challenge information for challenge-response dynamic tokens.
Quantum communication is an emerging cross-domain combining quantum theory and information theory, and people are increasingly concerned about the high-security information transmission capability of the quantum communication.
For example, chinese patent application 201510513004.4 discloses a mobile token identity authentication system based on a quantum cryptography network, in which dynamic token authentication of a quantum communication network is introduced. However, the security of the mobile terminal is not considered, and the dynamic password needs to be manually input in the application terminal, so that the operation is inconvenient.
Chinese patent application 201610843356.0 discloses a user identity authentication system and method, which introduces a quantum communication service station and quantum key fob and a method for implementing mutual authentication. However, only the authentication of the quantum communication user equipment equipped with the quantum key fob by the quantum communication service station is described, and the internal authentication of the application system in the quantum communication network, i.e., the authentication of the application terminal by the application server, is not described.
Problems in the prior art

Detailed Description
Referring to fig. 1, in the two-dimensional code authentication system based on the quantum communication network, in the quantum communication network, a plurality of quantum communication metropolitan area networks are accessed to a quantum communication trunk, and each quantum communication metropolitan area network can be accessed by a plurality of quantum communication service stations.
The quantum communication service station is internally provided with a plurality of servers such as authentication service, quantum key distribution service, and quantum random number service.
The authentication service is used for authenticating the identity of the user equipment of the quantum communication service station.
The quantum key distribution service is used for quantum key distribution and generation of a pairwise key with another quantum communication service station through a quantum communication metropolitan area network and a quantum communication trunk, and the key distribution protocol is preferably BB 84.
The quantum random number service is used for issuing quantum key fobs and quantum communication service stations with paired quantum random number key sets, and the issuing process can refer to the issuing process of the quantum key fobs in chinese patent application 201610843210.6.
After the quantum random number service issues a quantum key fob and a quantum communication service station with paired quantum random number key sets, the quantum communication service station issues the quantum key fob to user equipment of the quantum communication service station, and during actual use, the quantum key fob and the user equipment of the quantum communication service station have a one-to-one correspondence relationship. The user equipment of the quantum communication service station can be accessed to the quantum communication service station in the form of fixed user equipment and mobile user equipment. The fixed user equipment can be a common PC/MAC computer, an embedded device, or various servers, such as the application server of the invention. The mobile user equipment can be various mobile terminals such as mobile phones/PADs and the like. No matter what kind of quantum communication service station's equipment, it leaves the interface to dock the quantum key card, and can communicate with it. When the user equipment is accessed to the quantum communication service station, the user equipment and a specific quantum key card are in one-to-one correspondence binding relation, otherwise, the user equipment cannot be accessed to the quantum communication service station.
Regarding the implementation of the quantum key fob, reference may be made to chinese patent application 201610843210.6, which discloses a quantum communication service station, a quantum key management apparatus, and a key configuration network and method, and also describes the issue of the quantum key fob.
The application system can be various systems needing identity authentication and comprises an application server and a plurality of application terminals, wherein the application server runs a service program, and the application terminals run a service client program.

In the case of the aforementioned three application systems, the application servers are respectively: a background server of the access control system; an intelligent building background control center; a background server of the attendance system; the application terminals are respectively as follows: an access control device; an intelligent building controlled terminal; attendance machine terminal.
The application server is a user device of the quantum communication service station. The application end user must simultaneously own the mobile user devices of the quantum communication service station, and each mobile user device corresponds to one or more quantum key fobs.
The application terminal need not be, but may also be, a user equipment of the quantum communication service station. When the application terminal is a user device of the quantum communication service station, the application terminal and the application server are communicated through a quantum communication network. When the application terminal is not the user equipment of the quantum communication service station, a secure authentication and authorization network leading to the application terminal by the application server is arranged between the application terminal and the application server, namely the network for the application server to safely and effectively send the authentication result and the authorization information to the application terminal. The possibilities for secure authenticated authorized networks are: the communication network is ensured by keys such as a static key, a pre-distributed key, a dynamic token key, a mobile phone dynamic token key, a short message key and the like or CA certificates; a private secure communication network, etc.
Each application terminal has the capability of displaying the two-dimensional code image.
The mobile terminals needing to acquire and identify the two-dimensional codes are provided with cameras with enough resolution ratios for acquiring two-dimensional code images and functional modules for analyzing information contained in the two-dimensional codes from the two-dimensional code images, and the modules use technologies known by persons skilled in the art, so the implementation mode is not discussed in the invention.

The AT user holds the MT, which is currently paired with the MTK, and thus the AT user holds the MTK.
The AT user registers the MTK with the AS. The ID number distributed by the AS to the AT user is UID; the identity number of the quantum key card bound by the quantum key card is MTKID. The AS stores the UID and its corresponding MTKID to an account database. The AS can also store the user biological characteristics corresponding to the UID into an account database, such AS fingerprint characteristics, iris characteristics, face characteristics, vein characteristics, palm print characteristics and the like.

The two-dimensional code generation time is a time at which the two-dimensional code authentication information is generated. The two-dimensional code applicant ID is UID. The two-dimensional code applicant contact means is the IP address of the AT plus the port number.
The two-dimensional code related information recorded by the AS has a time range in which the authentication is valid, and the time range is called the maximum time difference of the two-dimensional code authentication. And after the time range of the authentication validity is exceeded, the two-dimensional code related information is regarded AS invalid information, and the two-dimensional code related information is deleted from the two-dimensional code database of the AS at irregular intervals. Preferably, the maximum time difference of the two-dimensional code authentication is 60 seconds. The maximum time difference of the two-dimensional code authentication can also be set to infinity.

3.6 MT generates two-dimension code response value
And the MT transmits the two-dimension code authentication information to the MTK, the MTK takes out the current authentication key, and the two-dimension code response value is calculated according to an agreed authentication algorithm by combining the two-dimension code challenge value in the two-dimension code authentication information. Preferably, the authentication algorithm is a challenge response algorithm, and the response mode is a keyed hash algorithm (e.g., HMAC).
3.7 the MT sends a response to the AS, including the two-dimension code ID, the MTKID and the two-dimension code response value
And the MT sends the information to the AS through the contact way of the two-dimension code generator.
Besides the above information, the user biological information collected by the MT, such as fingerprint information, iris information, face information, vein information, palm print information, etc., can be carried.

The two-dimensional code authentication time difference is equal to the difference between the two-dimensional code authentication time and the two-dimensional code generation time. If the two-dimension code authentication time difference is larger than the maximum two-dimension code authentication time difference, judging that the two-dimension code authentication time difference is illegal, returning a failure message and an error code to the MT, and ending the process; otherwise, continuing.
3.9 AS sends MTKID, two-dimension code challenge value and two-dimension code response value to QAS

Two-dimensional code authentication FLOW SQRA _ FLOW for simplifying operation
The QRA _ FLOW and QRA _ SFLOW described above both require the UID to be input to the AT in the first step, and are inconvenient to operate if the UID is input more complicated. To further facilitate user operation, the following FLOW SQRA _ FLOW may be used without the AT user entering the UID.
The direct involved party of SQRA _ FLOW is the same as QRA _ FLOW.
The AT user registers MTK to AS, the AS records MTKID to an account database of the AS, and the situation is recorded AS SQRA _ FLOW _ REG; or not registered, this case is denoted as SQRA _ FLOW _ UNREG. In the case of SQRA _ FLOW _ REG, the AS may further store user biological characteristics corresponding to the MTKID in an account database, such AS fingerprint characteristics, iris characteristics, face characteristics, vein characteristics, palm print characteristics, and the like.
