Description

Technical Field

[0001] The present application relates to the technical field of quantum encryption conference, and in particular to a method and device for implementing a quantum encryption conference. Background Art

[0002] With the continuous development of quantum encryption technology, the application of quantum encryption technology is becoming more and more extensive. For example, the prior art provides a video communication solution based on quantum encryption, including multiple video conferencing modules and a conference master control module. Each video conferencing module includes at least one video conferencing terminal and a corresponding quantum key machine. The conference master control module includes a conference control terminal and a corresponding master control quantum key machine. The master control quantum key machine and the quantum key machine are at least connected to the quantum network. The master control quantum key machine and all quantum key machines at least pre-store the network addresses and network accounts of all quantum key machines and the master control quantum key machine. The master control quantum key machine generates a point-to-point key pair including a first key and a second key with the quantum key machine of each video conferencing module respectively. The prior art effectively combines QKD technology with video communication to realize multi-party encrypted video communication.

[0003] QKD (Quantum Key Distribution) is a secure communication method that uses the properties of quantum mechanics to implement cryptographic protocols. It enables both parties to generate and share a random, secure key to encrypt and decrypt messages. If a third party tries to eavesdrop on the password, the two parties will notice it. This property is based on the basic principle of quantum mechanics, that is, any measurement of a quantum system will interfere with the system. Quantum key distribution is only used to generate and distribute keys, and does not transmit any substantial information. The key can be used in certain encryption algorithms to encrypt information.

[0004] In the existing quantum encryption conference technology solution, one video conferencing terminal corresponds to a quantum key machine, namely a QKD device, where the quantum key machine is used to generate and distribute quantum keys. After determining the quantum key between two video conferencing terminals, the two video conferencing terminals conduct quantum encryption communication based on the determined quantum key.

[0005] Although the above-mentioned existing technical solution can perform quantum encryption communication between two video conferencing terminals, since one video conferencing terminal corresponds to one quantum key machine in this technical solution, quantum encryption communication of the video conferencing terminals can often only be achieved in a fixed location, such as a laboratory with a quantum key machine or a company with a quantum key machine.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] Since quantum encryption calls in the prior art can only achieve quantum encryption between the two ends of the call, that is, both A and B use quantum call mobile phones to communicate and the communication process adopts quantum encryption call mode to achieve quantum encryption calls. Therefore, this application provides a method and device for implementing encrypted conferences.

[0051] Before explaining the solution provided by this application, a brief introduction to quantum SIM is given first. The "quantum security SIM card" used in quantum calling phones is a special SIM card that combines the functions of ordinary SIM cards and security chip functions. It does not occupy additional mobile phone card slots, and can provide ordinary SIM card functions such as operator network access authentication, and has pre-filled quantum keys to realize secure call functions. Quantum secure call When using the quantum secure call service, the user dials to trigger the authentication process and uses the pre-filled quantum key for authentication; at the same time, the quantum key is obtained in real time from the quantum key distribution network to encrypt the call voice, and a different quantum key is used for each call.

[0052] The following is an explanation of the method for implementing an encrypted conference provided by this application.

[0053] Embodiment 1

[0054] Reference Figure 1 , is a flow chart of the quantum encryption conference implementation method provided by this application, which is applied to a conference server, the conference server is pre-filled with quantum keys, and the conference server is connected to multiple network base stations. It should be noted that the conference server is used to provide data intermediary services for this quantum encryption conference. Depending on the service provider providing conference support, the conference server includes: a conference service module set in the operator server, or a service module set in the server of a third-party conference service provider. Please refer to Figure 2 and Figure 3 , Figure 2 Different quantum calling mobile phones are connected to the operator's server through corresponding network base stations to realize quantum encryption conference; Figure 3 Different quantum calling phones are connected to the third-party service provider's server through corresponding network base stations to realize quantum encryption conference.

[0055] It should be noted that the quantum encryption conference of the present application can be a voice conference or a video conference; accordingly, the conference data can be voice information or video information.

[0056] Specifically, Figure 1 The illustrated method embodiment may include the following steps:

[0057] Step S101: receiving a quantum encryption conference request sent by a mobile phone held by a conference initiating user through a corresponding network base station, wherein the mobile phone held by the conference initiating user is a quantum call mobile phone with a quantum security SIM card.

[0058] Step S102: Send the quantum encryption conference request to multiple mobile phones held by participating users through corresponding network base stations, wherein the mobile phones held by participating users include at least one quantum call mobile phone with a quantum security SIM card.

[0059] Step S103: upon receiving the joining requests sent by the mobile phones of the multiple participating users, the pre-filled quantum key is used to perform network authentication on the mobile phone of each participating user.

[0060] Specifically, multiple participating users click on the joining operation on their mobile phones to trigger the authentication process, and use the pre-filled quantum key for authentication; if the authentication fails, joining is denied, and if the authentication succeeds, the next step is entered.

[0061] Step S104: Determine whether the network access authentication is successful. If the authentication is successful, the user is allowed to join the conference and step S105 is executed. If the authentication fails, step S107 is executed.

[0062] Step S105: The mobile phone of the successfully authenticated participant establishes a quantum network connection with the conference server through the corresponding network base station and enters the conference.

[0063] Specifically, each participating user enters the conference and connects to the operator server through a network base station. At the same time, multiple users participating in the conference all establish connections with the operator server or a third-party conference service provider through the above steps.

[0064] Step S106: Encrypt the voice information and / or video information of the mobile phones of each user joining the conference during the conference based on the quantum key obtained in real time, so as to realize quantum encryption conference.

[0065] Specifically, each user obtains a quantum key in real time (the quantum key can be obtained from a quantum key distribution network), which is used to realize quantum encryption information transmission between the user and the operator's server, and to encrypt voice information and / or video information during the conference through the quantum key.

[0066] Step S107: Refuse to join the conference. It should be noted that at this time, the mobile phone held by the participating user has not established a quantum network connection with the conference server through the corresponding network base station.

[0067] In order to further improve the security of the meeting, the method may also include the following steps: regularly or irregularly re-executing the quantum key distribution operation between each user's mobile phone and the conference server to achieve real-time updating of the quantum key; and, based on the pre-filled quantum key, re-authenticating the user's mobile phone at set intervals.

[0068] It should be noted that the execution of the quantum key update operation depends on the set regular or irregular time nodes, is not limited by the execution order of steps 101 to S107, and can be updated before or after any step, or executed synchronously with steps 101 to S107, that is, the quantum key update runs through the entire process of executing steps S101 to S107.

[0069] It should be pointed out that the data transmission in the above conference process is as follows, taking the operator providing conference support as an example: any user A, whose voice information or video information during the conference is encrypted with a quantum key and sent to the operator server through a network base station. The operator server provides data intermediary services for this quantum encryption conference, and each participating user establishes a quantum encryption transmission relationship with the operator server, thereby realizing information exchange between different users. For example, after user A's voice information A is encrypted and sent to the operator server, the operator server will encrypt the voice information A according to the conference situation and send it to user B, user C, etc.

[0070] It should be noted that Figure 2 In the case shown, the operator provides conference support services. The server of the quantum encryption conference depends on the operator, but the operator is more often a communication service provider. For voice conferences or video conferences, specialized conference service providers are often required to provide richer services. Figure 2 In the scenario shown, a third-party service provider provides conference support services. The conference server of the conference support party accesses the quantum network through a network base station and connects to the mobile phones held by the participating users. The conference server of the third-party conference service provider replaces the operator's conference server.

[0071] Furthermore, once users use the conference service provided by the conference supporter, the conference supporter will charge a certain service fee, and the operator will also charge the user's information service fee, which will lead to insufficient user stickiness to the conference supporter. To solve this problem, the operator can specially mark the mobile phones of all users participating in the meeting. The marked mobile phones will receive signal enhancement services, thereby improving signal stability. The fee for the signal enhancement service is paid by the conference supporter to the operator, and the user does not need to pay the fee. In addition, all charges incurred by users in this meeting, such as encrypted call fees, traffic fees, call fees, video call fees, etc., will be counted and paid by the conference supporter after the meeting. Therefore, once users choose the quantum encryption conference service provided by a conference supporter, they can enjoy free signal enhancement services without consuming their own mobile phone call or traffic fees. For the conference supporter, customer stickiness is increased.

[0072] In the solution provided in this application, after the meeting is initiated, the quantum call mobile phone to be joined is first authenticated through the conference server provided by the operator or the third-party conference service provider, and after the authentication is successful, the conference data is encrypted based on the pre-charged quantum key, thereby improving the security of the meeting; further, the third-party conference service provider provides more professional online conference services, and through the cost-inclusive operation, it reduces the information service fees that users need to pay to the operator, which helps to improve user stickiness to third-party conference service providers.

[0073] Embodiment 2

[0074] Figure 1 In the method embodiment shown, whether the conference support is provided by the operator or a third-party service provider, the participants are required to have a quantum communication mobile phone. If a participant does not have a quantum secure communication mobile phone, the entire quantum encryption conference cannot be realized. Please refer to Figure 5 If a conference member holds an ordinary mobile phone instead of a quantum phone, he or she needs to find a mobile phone among other quantum phones as a matching mobile phone for the ordinary mobile phone. The voice and video information of the ordinary mobile phone must first be transmitted to the matching mobile phone through the ordinary network, and then the matching mobile phone will transmit it to the server after quantum encryption, so that the ordinary mobile phone can participate in the entire quantum encryption conference. In this way, at the expense of confidentiality, quantum encryption conferences can adapt to more usage scenarios.

[0075] Since the communication between an ordinary mobile phone and its matching mobile phone in the prior art is non-quantum encrypted, there is a risk of being eavesdropped. To solve this problem, this application provides another method for implementing quantum encryption conferences, see Figure 4 and Figure 5 , Figure 4 Another flow chart of the method for implementing a quantum encryption conference provided in this application, it should be noted that: Figure 4 In the method embodiment shown, the mobile phones held by the participating users include at least one quantum call mobile phone with a quantum security SIM card and an ordinary mobile phone, and the ordinary mobile phone does not have a quantum SIM card. Figure 4 The illustrated method embodiment may include the following steps:

[0076] Step S201: receiving a quantum encryption conference request sent by a mobile phone held by a conference initiating user through a corresponding network base station, wherein the mobile phone held by the conference initiating user is a quantum call mobile phone with a quantum security SIM card.

[0077] Step S202: Send the quantum encryption conference request to multiple mobile phones held by participating users through corresponding network base stations, wherein the mobile phones held by participating users include at least one quantum call mobile phone with a quantum security SIM card.

[0078] Step S203: upon receiving the joining requests sent by the mobile phones of the multiple participating users, the pre-filled quantum key is used to perform network authentication on the mobile phone of each participating user.

[0079] Step S204: The mobile phone of the successfully authenticated participant establishes a quantum network connection with the conference server through the corresponding network base station and enters the conference.

[0080] Step S205: Based on the preset mobile phone matching rules, a mobile phone is selected from the quantum call mobile phones that have joined the conference as a matching mobile phone for the ordinary mobile phone.

[0081] In one case, a mobile phone terminal can be selected from the quantum call mobile phones that have joined the meeting as a matching mobile phone for the ordinary mobile phone according to the following mobile phone terminal matching rules: one mobile phone is selected from the quantum call mobile phones that have joined the meeting as the current matching mobile phone; after completing the current conference data transmission or according to the set time interval, a mobile phone terminal is re-matched from the remaining quantum call mobile phones as the current matching mobile phone, and the cycle is repeated in sequence.

[0082] The following is a specific example to illustrate the real-time update process of the matching mobile phone corresponding to an ordinary mobile phone. Figure 5As shown, there is an ordinary mobile phone and four quantum call mobile phones (i.e., quantum call mobile phone 1, quantum call mobile phone 2, quantum call mobile phone 3, and quantum call mobile phone 4). In the process of matching ordinary mobile phones with quantum call mobile phones, the matching mobile phones corresponding to the ordinary mobile phones need to be updated in real time in these four quantum call mobile phones. For example, the data of the ordinary mobile phone is sent to quantum call mobile phone 1 at the first time and then encrypted and transmitted to the conference server, the data of the ordinary mobile phone is sent to quantum call mobile phone 2 at the second time and then encrypted and transmitted to the conference server, the data of the ordinary mobile phone is sent to quantum call mobile phone 3 at the third time and then encrypted and transmitted to the conference server, the data of the ordinary mobile phone is sent to quantum call mobile phone 4 at the fourth time and then encrypted and transmitted to the conference server, and then, at the next time, i.e., the fifth time, the data of the ordinary mobile phone needs to be sent to quantum call mobile phone 1 again and encrypted and transmitted to the conference server, and so on. This cycle increases the difficulty of eavesdropping by eavesdroppers and improves the confidentiality of the meeting.

[0083] Step S206: The voice information and / or video information of the ordinary mobile phone is transmitted to the matching mobile phone via the ordinary network, and the matching mobile phone quantum encrypts the voice information and / or video information and transmits it to the conference server, so that the ordinary mobile phone can participate in the quantum encryption conference.

[0084] It should be noted that Figure 4 Steps S201 to S204 in the method embodiment shown are similar to Figure 1 Steps S101 to S104 in the method embodiment shown are similar, and the relevant parts can be found in Figure 1 The specific content of the method embodiment shown will not be repeated here.

[0085] From the above, we can see that Figure 4 The method embodiment shown has Figure 1 All the beneficial effects of the method embodiments shown are shown. In addition, quantum encryption conferences can also be achieved for non-quantum call mobile phones, that is, ordinary mobile phones, expanding the application scenarios of quantum encryption technology in conference communication security.

[0086] It should be noted that, for the method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the order of the actions described, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions involved are not necessarily required by the present application.

[0090] Specifically, Figure 6 The device embodiment shown may include the following elements:

[0093] The mobile phone authentication unit 330 is used to use the pre-filled quantum key to perform network access authentication on the mobile phone held by each participating user when receiving the joining request sent by the mobile phones held by the multiple participating users. If the authentication is successful, the participating user is allowed to join the meeting; and if the authentication fails, the participating user's mobile phone is denied from joining the meeting.

[0094] A conference establishing unit 340 is used for the mobile phone of the successfully authenticated participant to establish a quantum network connection with the conference server through the corresponding network base station and enter the conference;

[0095] The conference data encryption unit 350 is used to encrypt the voice information and / or video information of the mobile phones of each user joining the conference during the conference based on the quantum key obtained in real time, so as to realize quantum encryption conference.

[0096] In one scenario, the device also includes a key update unit (not shown), which is used to periodically or irregularly re-execute the quantum key distribution operation between each user's mobile phone and the conference server to achieve real-time update of the quantum key; and, based on the pre-injected quantum key, re-authenticate the user's mobile phone at a set interval.

[0097] Furthermore, the mobile phones held by the participating users include at least one quantum call mobile phone with a quantum security SIM card and an ordinary mobile phone, and the ordinary mobile phone does not have a quantum SIM card. The device also includes: a mobile phone matching unit, which is used to select a mobile phone from the quantum call mobile phones that have joined the meeting as a matching mobile phone for the ordinary mobile phone based on a preset mobile phone matching rule; an ordinary network transmission unit, which is used to transmit the voice information and / or video information of the ordinary mobile phone to the matching mobile phone via the ordinary network, and the matching mobile phone transmits the voice information and / or video information to the conference server after quantum encryption, so that the conference data encryption unit can perform quantum key encryption on the voice information and / or video information transmitted on the ordinary network to enable the ordinary mobile phone to participate in the quantum encryption conference.

[0098] In one scenario, the mobile phone matching unit (not shown) is specifically used to select one from the quantum call mobile phones joining the meeting as the current matching mobile phone; after completing the current conference data transmission or according to the set time interval, re-match a mobile phone from the remaining quantum call mobile phones as the current matching mobile phone, and cycle in sequence.

[0099] In the solution provided in this application, after the meeting is initiated, the quantum calling mobile phone to be joined is first authenticated through the conference server provided by the operator or the third-party conference service provider, and after the authentication is successful, the conference data is encrypted based on the pre-charged quantum key, thereby improving the security of the meeting; further, the third-party conference service provider provides more professional online conference services, and through the cost-sharing operation, reduces the information service fees that users need to pay to the operator, thereby helping to improve user stickiness to the third-party conference service provider; in addition, for non-quantum calling mobile phones, that is, ordinary mobile phones, quantum encryption conferences can also be realized, which expands the application scenarios of quantum encryption technology in conference communication security.
