Description

Technical Field

[0001] This application relates to the field of quantum encrypted conferencing technology, and in particular to a method and apparatus for implementing quantum encrypted conferencing. Background Technology

[0002] With the continuous development of quantum encryption technology, its applications are becoming increasingly widespread. For example, existing technologies provide a video communication scheme based on quantum encryption, including multiple video conferencing modules and a central control module. Each video conferencing module includes at least one video conferencing terminal and a corresponding quantum key generator. The central control module includes a conference control terminal and a corresponding central control quantum key generator. The central control quantum key generator and all quantum key generators are connected to a quantum network. The central control quantum key generator and all quantum key generators pre-store the network addresses and network accounts of all quantum key generators and the central control quantum key generator. The central control quantum key generator generates point-to-point key pairs, including a first key and a second key, with each video conferencing module's quantum key generator. Existing technologies effectively combine QKD technology with video communication to achieve multi-party encrypted video communication.

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

[0004] In existing quantum-encrypted conferencing technology solutions, one video conferencing terminal corresponds to one quantum key generator (QKD) device. The quantum key generator 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-encrypted communication based on the determined quantum key.

[0005] Although the above-mentioned existing technical solutions can enable quantum encrypted communication between two video conferencing terminals, since each video conferencing terminal corresponds to a quantum key machine, the quantum encrypted communication of video conferencing terminals can often only be realized in a fixed location, such as a laboratory or company that owns a quantum key machine. Summary of the Invention

[0015] Optionally, the mobile devices held by the participating users include at least one quantum-enabled phone with a quantum-secure SIM card and one ordinary phone, wherein the ordinary phone does not have a quantum SIM card, and the method further includes:

[0016] Based on preset mobile phone matching rules, select one mobile phone from among the quantum communication mobile phones that have joined the conference as the matching mobile phone for the ordinary mobile phone;

[0017] The voice and / or video information of the ordinary mobile phone is transmitted to the matching mobile phone via an ordinary network, and the matching mobile phone transmits the voice and / or video information to the conference server after quantum encryption, so that the ordinary mobile phone can participate in the quantum encrypted conference.

[0018] Optionally, the step of selecting one mobile phone from among the quantum calling phones that have joined the conference as the matching phone for the ordinary mobile phone based on preset mobile phone matching rules, and transmitting the voice information and / or video information of the ordinary mobile phone to the matching phone via an ordinary network, includes:

[0019] Select one of the quantum calling phones that have joined the meeting as the current matching phone;

[0020] After the current conference data transmission is completed, or at a set time interval, a new mobile phone is selected from the remaining quantum calling phones as the current matching phone, and this process is repeated in turn.

[0021] Optionally, the step of authenticating each participant's mobile phone using the pre-charged quantum key upon receiving a membership request from the mobile devices of the plurality of participating users further includes:

[0022] If authentication fails, you will be refused entry to the meeting.

[0023] Secondly, this application discloses a quantum-encrypted conference implementation device applied to a conference server, wherein the conference server is pre-charged with a quantum key and is connected to multiple network base stations, and the device includes:

[0024] The meeting initiation unit is used to receive a quantum-encrypted meeting request sent by the mobile phone held by the meeting initiator through the corresponding network base station. The mobile phone held by the meeting initiator is a quantum-calling mobile phone with a quantum-safe SIM card.

[0025] The meeting request distribution unit is used to send the quantum-encrypted meeting request to the mobile phones of multiple participating users through the corresponding network base stations, wherein the mobile phones of the participating users include at least one quantum-calling mobile phone with a quantum-safe SIM card;

[0026] The mobile authentication unit is used to authenticate each mobile device held by the participating users using the pre-charged quantum key when it receives a meeting access request sent by the mobile devices held by the multiple participating users. If the authentication is successful, the user is allowed to join the meeting.

[0027] The meeting setup unit is used to enable successfully authenticated participants to establish a quantum network connection between their mobile devices and the meeting server via the corresponding network base station and enter the meeting.

[0028] The conference data encryption unit is used to encrypt the voice and / or video information of each user's mobile device during the conference based on the real-time acquired quantum key, thereby realizing quantum-encrypted conferencing.

[0029] Optionally, the conference server includes: a conference service module located within the operator's server, or a service module located within the server of a third-party conference service provider.

[0030] Optionally, the device further includes a key update unit, used to periodically or irregularly re-execute the quantum key distribution operation between each user's mobile device and the conference server to achieve real-time updating of the quantum key; and to perform a re-authentication operation on the user's mobile device according to a set interval based on the pre-charged quantum key.

[0032] The mobile phone matching unit is used to select one mobile phone from the quantum communication mobile phones that have joined the conference as the matching mobile phone for the ordinary mobile phone, based on the preset mobile phone matching rules.

[0033] A standard network transmission unit is used to transmit the voice and / or video information of the standard mobile phone to a paired mobile phone via a standard network. The paired mobile phone then performs quantum encryption on the voice and / or video information before transmitting it to the conference server. This allows the conference data encryption unit to perform quantum key encryption on the voice and / or video information transmitted via the standard network, enabling the standard mobile phone to participate in the quantum-encrypted conference.

[0034] Optionally, the mobile phone matching unit is specifically used to select one of the quantum calling mobile phones that have joined the conference as the current matching mobile phone; after the current conference data transmission is completed or according to a set time interval, it re-matches a mobile phone from the remaining quantum calling mobile phones as the current matching mobile phone, and repeats this process in turn.

[0039] The technical solution provided in this application may include the following beneficial effects:

[0040] After the meeting is initiated, the incoming quantum-enabled mobile phones are first authenticated by the meeting server provided by the operator or a third-party meeting service provider. After successful authentication, the meeting data is encrypted based on the pre-charged quantum key, thereby improving the security of the meeting. Furthermore, the third-party meeting service provider offers more professional online meeting services, reducing the information service fees that users need to pay to the operator through a fee-based operation, which helps to increase user loyalty to the third-party meeting service provider. In addition, quantum-encrypted meetings can also be achieved for non-quantum-enabled mobile phones, i.e., ordinary mobile phones, expanding the application scenarios of quantum encryption technology in the security of meeting communications.

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

[0050] Because existing quantum-encrypted calls can only achieve quantum encryption between the two ends of the call—meaning both A and B must use quantum-encrypted phones and the entire communication process must employ quantum-encrypted call mode—this application provides a method and apparatus for implementing encrypted conferencing.

[0051] Before explaining the solution provided in this application, let's briefly introduce quantum SIM. The "quantum secure SIM card" used in quantum calling phones is a special SIM card that combines the functions of a regular SIM card and a secure chip. It doesn't occupy an extra SIM card slot and provides both the authentication functions of a regular SIM card (such as network access authentication) and the secure calling function enabled by pre-charged quantum keys. When using the quantum secure calling service, the user dials to trigger the authentication process, using a pre-charged quantum key for authentication; simultaneously, a quantum key is obtained in real-time from the quantum key distribution network to encrypt the voice call, with a different quantum key used for each call.

[0052] The following describes the encrypted conferencing implementation method provided in this application.

[0053] Example 1

[0054] Reference Figure 1 This is a flowchart illustrating a quantum-encrypted conference implementation method provided in this application, applied to a conference server. The conference server is pre-loaded with quantum keys and connected to multiple network base stations. It should be noted that this conference server provides data intermediary services for this quantum-encrypted conference. Depending on the service provider offering conference support, the conference server may include: a conference service module located within an operator's server, or a service module located within a third-party conference service provider's server. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 , Figure 2 Different quantum-enabled mobile phones connect to the operator's server through corresponding network base stations, thereby enabling quantum-encrypted conferencing; Figure 3 Different quantum-enabled mobile phones connect to third-party service providers' servers through corresponding network base stations, thereby enabling quantum-encrypted meetings.

[0055] It should be noted that the quantum encryption conference in this application can be either an audio conference or a video conference; correspondingly, the conference data can be either audio information or video information.

[0056] Specifically, Figure 1 The method embodiments shown may include the following steps:

[0057] Step S101: Receive a quantum-encrypted conference request sent by the mobile phone of the conference initiator through the corresponding network base station. The mobile phone of the conference initiator is a quantum-communication mobile phone with a quantum-safe SIM card.

[0058] Step S102: The quantum-encrypted conference request is sent to the mobile phones of multiple participating users through the corresponding network base stations, wherein the mobile phones of the participating users include at least one quantum-calling mobile phone with a quantum-safe SIM card.

[0059] Step S103: Upon receiving the membership request sent by the mobile devices of the multiple participating users, the pre-charged quantum key is used to perform network access authentication on the mobile devices of each participating user.

[0060] Specifically, multiple participating users click to join the meeting on their mobile devices, triggering the authentication process, which uses pre-filled quantum keys for authentication; if authentication fails, the user is refused entry; if authentication succeeds, the user proceeds to the next step.

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

[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 meeting and connects to the operator's server through a network base station. At the same time, multiple users participating in the meeting establish a connection with the operator's server or a third-party meeting service provider through the above steps.

[0064] Step S106: Encrypt the voice and / or video information of each user's mobile device during the meeting based on the real-time acquired quantum key, thereby realizing a quantum-encrypted meeting.

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

[0066] Step S107: Reject joining the meeting. It should be noted that at this point, the mobile device held by the participating user has not established a quantum network connection with the meeting server through the corresponding network base station.

[0067] To further enhance the security of the meeting, the method may also include the following steps: periodically or irregularly re-performing the quantum key distribution operation between each user's mobile device and the meeting server to achieve real-time updates of the quantum key; and re-authenticating the user's mobile device according to a set interval based on the pre-charged quantum key.

[0068] It should be noted that the execution of the quantum key update operation depends on the set periodic or irregular time nodes, is not restricted 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 noted that the data transmission in the above meeting process is as follows, taking the example of a network operator providing meeting support: Any user, A, whose voice or video information during the meeting is encrypted using a quantum key, is sent to the operator's server via a network base station. The operator's server provides data intermediary services for this quantum-encrypted meeting. Each participating user establishes a quantum-encrypted transmission relationship with the operator's server, thereby enabling information exchange between different users. For example, after user A's voice information A is encrypted and sent to the operator's server, the operator's server then encrypts voice information A again and sends it to users B, C, etc., according to the meeting requirements.

[0070] It should be noted that, Figure 2 The scenario shown depicts a scenario where the operator provides conference support services. The server for the quantum-encrypted conference relies on the operator, but operators primarily act as communication service providers. For audio or video conferencing, dedicated conference service providers are often needed to offer a wider range of services. Figure 2 In the scenario shown, where a third-party service provider offers meeting support services, the meeting support provider's meeting server connects to the quantum network via a network base station and is linked to the mobile devices of the participants. The third-party meeting service provider's meeting server replaces the operator's meeting server.

[0071] Furthermore, once users utilize the meeting services provided by a meeting support provider, the provider charges a service fee, while the operator simultaneously charges the user a data service fee. This can lead to insufficient user loyalty to the meeting support provider. To address this issue, operators can specially label the mobile devices of all participants. Labeled devices will receive a signal enhancement service, improving signal stability. The cost of this signal enhancement service is paid by the meeting support provider to the operator, without the user incurring any payment. Additionally, all charges incurred by users during the meeting, such as encrypted call fees, data charges, call charges, and video call fees, will be tallied and paid by the meeting support provider after the meeting concludes. Thus, once a user selects a meeting support provider's quantum encrypted meeting service, they can enjoy free signal enhancement without consuming their own mobile phone's call or data charges, increasing customer loyalty for the meeting support provider.

[0072] In the solution provided in this application, after the meeting is initiated, the quantum calling mobile phones to be joined are first authenticated through the meeting server provided by the operator or a third-party meeting service provider. After successful authentication, the meeting data is encrypted based on the pre-charged quantum key, thereby improving the security of the meeting. Furthermore, the third-party meeting service provider provides more professional online meeting services. Through a fee-based operation, the information service fees that users need to pay to the operator are reduced, which helps to increase user loyalty to the third-party meeting service provider.

[0073] Example 2

[0074] Figure 1 The illustrated method embodiment, regardless of whether conference support is provided by an operator or a third-party service provider, requires each participating user to possess a quantum-secure communication phone. If any participating user does not have a quantum-secure communication phone, the entire quantum-encrypted conference cannot be conducted. Please refer to [link to relevant documentation]. Figure 5 If a participant in a meeting uses a regular mobile phone instead of a quantum-enabled phone, a matching phone must be found among other quantum-enabled phones. The voice and video data from the regular phone are first transmitted over a regular network to the matching phone, and then quantum-encrypted before being transmitted to the server, thus enabling the regular phone to participate in the entire quantum-encrypted meeting. This approach, while sacrificing some confidentiality, allows quantum-encrypted meetings to be adapted to a wider range of use cases.

[0075] Since communication between ordinary mobile phones and their paired phones in existing technologies is not quantum encrypted, there is a risk of eavesdropping. To address this issue, this application provides an alternative quantum-encrypted conferencing method. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 , Figure 4 Another flowchart for the quantum cryptographic meeting implementation method provided in this application should be noted. Figure 4 In the illustrated method embodiment, the mobile devices held by the participating users include at least one quantum-enabled phone with a quantum-secure SIM card and one ordinary phone, wherein the ordinary phone does not have a quantum SIM card. Figure 4 The method embodiment shown may include the following steps:

[0076] Step S201: Receive a quantum-encrypted conference request sent by the mobile phone of the conference initiator through the corresponding network base station. The mobile phone of the conference initiator is a quantum-communication mobile phone with a quantum-safe SIM card.

[0077] Step S202: The quantum-encrypted conference request is sent to the mobile phones of multiple participating users through the corresponding network base stations, wherein the mobile phones of the participating users include at least one quantum-calling mobile phone with a quantum-safe SIM card.

[0078] Step S203: Upon receiving the membership request sent by the mobile devices of the multiple participating users, the pre-charged quantum key is used to perform network access authentication on the mobile devices 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, select one mobile phone from the quantum calling mobile phones that have joined the conference as the matching mobile phone for the ordinary mobile phone.

[0081] In one scenario, the following matching rules can be used to select one of the quantum communication phones that have joined the conference as the matching phone for the ordinary phone: Select one of the quantum communication phones that have joined the conference as the current matching phone; after the current conference data transmission is completed or at a set time interval, re-match a phone from the remaining quantum communication phones as the current matching phone, and repeat this process.

[0082] The following is a specific example to illustrate the real-time update process of matching mobile phones for ordinary mobile phones, such as... Figure 5As shown, there is one ordinary mobile phone and four quantum communication phones (i.e., quantum communication phone 1, quantum communication phone 2, quantum communication phone 3, and quantum communication phone 4). During the pairing process between the ordinary mobile phone and the quantum communication phones, the matching phone for the ordinary mobile phone needs to be updated in real time among these four quantum communication phones. For example, the data of the ordinary mobile phone is sent to quantum communication phone 1 and encrypted before being transmitted to the conference server at the first moment. The data of the ordinary mobile phone is sent to quantum communication phone 2 and encrypted before being transmitted to the conference server at the second moment. The data of the ordinary mobile phone is sent to quantum communication phone 3 and encrypted before being transmitted to the conference server at the third moment. The data of the ordinary mobile phone is sent to quantum communication phone 4 and encrypted before being transmitted to the conference server at the fourth moment. Then, at the next moment, i.e., the fifth moment, the data of the ordinary mobile phone needs to be sent to quantum communication phone 1 again and encrypted before being transmitted to the conference server. This cycle continues, thereby increasing the difficulty for eavesdroppers and improving the confidentiality of the conference.

[0083] Step S206: The voice information and / or video information of the ordinary mobile phone is transmitted to the matching mobile phone via an ordinary network, and the matching mobile phone transmits the voice information and / or video information to the conference server after quantum encryption, so as to enable the ordinary mobile phone to participate in the quantum encrypted conference.

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

[0085] From the above, we can see that Figure 4 The method embodiments shown have Figure 1 The illustrated method embodiments demonstrate all the beneficial effects. Furthermore, quantum-encrypted conferences can also be achieved for non-quantum-enabled mobile phones, i.e., ordinary mobile phones, thus expanding the application scenarios of quantum encryption technology in conference communication security.

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

[0087] Example 3

[0088] The quantum-encrypted conference implementation device provided in this application is described below.

[0089] Please see Figure 6 This is a structural diagram of a quantum-encrypted conference implementation device provided in this application, applied to a conference server. The conference server is pre-charged with quantum keys and is connected to multiple network base stations. The conference server includes: a conference service module set in an operator's server, or a service module set in a third-party conference service provider's server.

[0090] Specifically, Figure 6 The illustrated device embodiment may include the following units:

[0091] The meeting initiation unit 310 is used to receive a quantum-encrypted meeting request sent by the mobile phone held by the meeting initiator through the corresponding network base station. The mobile phone held by the meeting initiator is a quantum-calling mobile phone with a quantum-safe SIM card.

[0092] The meeting request distribution unit 320 is used to send the quantum-encrypted meeting request to the mobile phones of multiple participating users through the corresponding network base stations, wherein the mobile phones of the participating users include at least one quantum calling mobile phone with a quantum-safe SIM card;

[0093] The mobile authentication unit 330 is used to perform network access authentication on each mobile device of the participating users using the pre-charged quantum key when it receives a meeting access request sent by the mobile devices of the multiple participating users. If the authentication is successful, the user is allowed to join the meeting; and if the authentication fails, the user is denied access to the meeting.

[0094] The meeting establishment unit 340 is used for the mobile devices of successfully authenticated participants to establish a quantum network connection with the meeting server through the corresponding network base station and enter the meeting.

[0095] The conference data encryption unit 350 is used to encrypt the voice and / or video information of each user's mobile device during the conference based on the real-time acquired quantum key, thereby realizing quantum encrypted conferencing.

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

[0097] Furthermore, the mobile devices held by the participating users include at least one quantum-enabled mobile phone with a quantum-secure SIM card and one ordinary mobile phone. The ordinary mobile phone does not have a quantum SIM card. The device further includes: a mobile phone matching unit, used to select one mobile phone from among the quantum-enabled mobile phones that have joined the conference as the matching mobile phone for the ordinary mobile phone based on preset mobile phone matching rules; and an ordinary network transmission unit, used to transmit the voice information and / or video information of the ordinary mobile phone to the matching mobile phone via an ordinary network, and the matching mobile phone quantum-encrypts the voice information and / or video information before transmitting it to the conference server, so that the conference data encryption unit can encrypt the voice information and / or video information transmitted over the ordinary network with a quantum key to enable the ordinary mobile phone to participate in the quantum-encrypted conference.

[0098] In one scenario, the mobile phone matching unit (not shown) is specifically used to select one of the quantum calling mobile phones that have joined the conference as the current matching mobile phone; after the current conference data transmission is completed or according to a set time interval, it re-matches a mobile phone from the remaining quantum calling mobile phones as the current matching mobile phone, and repeats this process in a loop.

[0099] In the solution provided in this application, after the meeting is initiated, the incoming quantum-enabled mobile phones are first authenticated by the meeting server provided by the operator or a third-party meeting service provider. After successful authentication, the meeting data is encrypted based on the pre-charged quantum key, thereby improving the security of the meeting. Furthermore, the third-party meeting service provider offers more professional online meeting services, reducing the information service fees that users need to pay to the operator through a fee-based operation, which helps to increase user loyalty to the third-party meeting service provider. In addition, quantum-encrypted meetings can also be achieved for non-quantum-enabled mobile phones, i.e., ordinary mobile phones, expanding the application scenarios of quantum encryption technology in meeting communication security.
