A method for authentication between multiple communication parties is disclosed. Authentication can be carried out by the means of each communication party having a device having a physical unclonable function. To make this possible, the devices have a known quantum correlation that can be used in conjunction with entangled photons to verify the identities of the devices.

The application relates to the fields of secure multi-party communication and quantum cryptography, and discloses a dynamic quantum message authentication method capable of identifying suspension, which comprises the following steps: a semi-quantum trusted third party (SQ-TTP) screening honest participant phase, in which the SQ-TTP dynamically groups the participants, randomly selects part of the participants to form a small quantum communication network for message transmission, and screens out no less than the number of groups of honest participants according to the message authentication result; a parallel transmission of quantum messages of each group phase, in which the SQ-TTP specifies the screened honest participants as the receivers of each group, and the participants in the group complete the message transmission by adopting a quantum message transmission mode similar to that in the screening phase; and a stage of transmitting the received messages to a server by the SQ-TTP and the receivers of each group, in which the server decrypts the messages by using the key sent by the SQ-TTP, and authenticates the messages by measuring the trap qubits. The application is applicable to a large-scale quantum communication network, and can reduce the consumption of quantum resources and improve the message transmission efficiency by dynamic grouping and parallel transmission.

The invention relates to the technical field of multi-party communication, in particular to a multi-terminal calling method and system, and the method comprises the following steps: obtaining real-time network activity and stability indexes of terminals, screening stable terminals and merging concurrent requests, mapping resource conflict channels, screening abnormal nodes and sorting candidate channels, and matching a media stream structure distribution path. And generating a forwarding path mapping table. According to the invention, the network activity state of the terminal is monitored in real time and stably connected equipment is screened out, so that the terminal with frequent link breaking is prevented from accessing a communication path, the stability of a call link is remarkably improved, and resource redundancy caused by repeated requests of the terminal is effectively avoided by merging and analyzing the concurrent call requests, so that the service life of the terminal is prolonged. By detecting the load state of the resource node and the channel overlapping use condition, mapping and identification of call conflicts are realized, it is ensured that a media stream forwarding path is kept within a controllable range, the transmission blocking risk is reduced, and the overall communication efficiency and service continuity are improved.

A method for providing multi-party communication using a large language model (LLM) is provided. The method begins with receiving an input message from a user device associated with a plurality of communicating parties participating in a scenario. The method continues with the following operations: generating text input cues for LLM based on the scene template. The method further includes sending the text input cue word to the LLM. The LLM analyzes the text input cues to compile a response output of the LLM. The method continues by analyzing the response output of the LLM to generate an output message to be sent to one or more of the plurality of communicators. The method also includes sending an output message from the communication endpoint representing the LLM to a user device associated with one or more of the plurality of communicators.

The invention relates to the technical field of wireless communication, and provides a low-power-consumption quasi-duplex voice communication method and device. Wherein the communication node enters a sleep state after being maintained for a time exceeding a preset time; in the sleep state, the radio frequency unit of the communication node is awakened every interval period duration; after the radio frequency unit is awakened each time, the radio frequency unit enters the sleep state again after monitoring window duration; when the radio frequency unit is awakened, detecting whether a preamble awakening signal exists in a channel; the communication node sends a preamble wake-up signal to a target equipment node before sending the service data; and the target equipment node receives the preamble wake-up signal, wakes up a local main control unit, and turns on the radio frequency unit to enable the target equipment node to enter a receiving state. According to the method and the device, the problems that the call role can be switched in half-duplex talkback only by the language and manual operation of a user, and a key triggering mode is easy to cause conflicts in a multi-party communication scene are solved.
