Problems solved by technology

[0011] 1. In the prior art, in the process of using dynamic tokens for identity authentication, application terminal users need to manually input dynamic tokens, which is too cumbersome to operate and has potential safety hazards
[0012] 2. In the prior art, only the user equipment of the quantum communication network is authenticated, and the user of the user equipment of the quantum communication network is not authenticated
[0013] 3. In the existing technology, the account authentication center of each application server is independent, and the application terminal needs to maintain multiple sets of accounts and their corresponding passwords, which is inconvenient to manage

Embodiment 1

[0060] NFC Authentication Flow QRA_FLOW

[0061] The parties directly involved in QRA_FLOW are the mobile terminal MT, the application terminal AT (its identification number is ATID; the current quantum key card is ATK, and its identification number is ATKID), the application server AS (the current quantum key card is ASK, and its The identification number is ASKID), the authentication service module QAT of the quantum communication service station corresponding to the ATK current key (its identification number is QATID), the authentication service module QAS of the quantum communication service station corresponding to the current key of ASK (its The identification number is QASID).

[0062] AT users hold MT. MT has its unique identification information MTINFO, MTINFO includes but not limited to MT's IMEI code, mobile communication number and network card MAC address, etc.; in the case of MT_IS_QT, MT has a quantum key card (let the quantum key card be MTK, Its identificati...

[0153] NFC authentication simplified process QRA_SFLOW

[0154] The special case of QRA_FLOW is that when the quantum communication service station corresponding to the quantum key card used by the application server and the application terminal is the same, that is, when there is only QAT and no QAS and QMT, the process is appropriately simplified. Its specific process is similar to the QRA_FLOW in Embodiment 1, except that several steps of communication among QAS, QMT, and QAT are omitted.

[0155] See image 3 , QRA_SFLOW is as follows:

[0156] 4.1 MT sends user access request to AT

[0157] 4.2 Information about AT forming NFC authentication

[0158] 4.3 AT sends ATID and NFC authentication information to MT

[0159] 4.4 MT generates NFC authentication response value

[0160] 4.5 MT sends authentication response to AS

[0161] 4.6 AS judges the authentication response of MT and generates NFC authentication response value

[0162] 4.6.1 Legality Judgment of Identity...

Embodiment 3

[0186] Simplified operation of the NFC authentication process SQRA_FLOW

[0187] For the aforementioned QRA_FLOW and QRA_SFLOW, the first step needs to input the UID to the MT. If the input of the UID is complicated, the operation will be inconvenient. For further convenience of user operation, the following flow SQRA_FLOW without inputting UID can be used.

[0188] The parties directly involved in SQRA_FLOW are the same as QRA_FLOW.

[0189] AT users hold MT to register with AS. AS records MTINFO to the account database of AS. AS can also store the user's biological characteristics corresponding to MTINFO in the account database, such as fingerprint characteristics, iris characteristics, face characteristics, vein characteristics, palmprint characteristics, etc.

[0190] See Figure 4 , SQRA_FLOW is as follows:

[0191] 5.1 MT sends user access request to AT

[0192] The MT establishes an NFC connection with the AT. The user directly sends the user access request on th...

Abstract

The invention discloses an NFC authentication system based on quantum encryption, which includes an application server, an application terminal, and a mobile terminal, and a quantum communication service station. The application server and the application terminal are respectively equipped with quantum key cards; During authentication, the mobile terminal applies for and obtains NFC authentication information from the application terminal through NFC transmission, and sends an authentication response with the NFC authentication information to the application server; the application server, in the configured quantum key card, according to the NFC authentication information and use the stored quantum key to calculate the first NFC authentication response value, and send the first NFC authentication response value to the application terminal, and the application terminal performs the first NFC authentication response value via the quantum communication service station Certification, and perform related business based on the certification results. In the present invention, the NFC authentication operation using the mobile terminal is fast and convenient, and the security is high.

Description

technical field [0001] The invention relates to the field of network security communication, in particular to an NFC authentication system based on a quantum communication network. Background technique [0002] During identity authentication, static passwords are easy to be stolen by malware, or cracked violently because they are fixed. In order to solve the security problem of static passwords, dynamic token technology has become popular. [0003] Dynamic tokens replace traditional static passwords with one-time passwords generated based on three variables: time, event, and key. Each dynamic token card has a unique key, which is stored on the server side at the same time. Each time the dynamic token card and the server are authenticated according to the same key, the same random parameters (time, event) and The same algorithm calculates the dynamic token to be authenticated, so as to ensure the consistency of the password bilaterally and realize the identity authenticatio...
