The present invention provides a long-distance continuous variable quantum key distribution method based on Gaussian modulation coherent state, including: Step A: The continuous variable initial key distribution step refers to using the sender Alice to perform Gaussian modulation through the coherent state and pass through the optical fiber After the long-distance transmission of the channel, the receiving party Bob performs demodulation and detection to obtain the initial continuous key data; Step B: refers to using the data post-processing algorithm to preprocess, error correct and enhance the security of the initial continuous key data obtained, Get the ultimate secure binary bit key. The invention can extend the safe communication distance of the CVQKD system based on Gaussian modulation coherent state to 100-150km.

The invention relates to flight management system and method thereof based on multi-task parallel processing. The system comprises an electronic flight instrument system display unit, a multifunctional control display unit, a flight management system processing unit and a display unit with a control button, wherein the multifunctional control display unit is used for maintaining existing functions of formulating and executing a flight plan; and the flight management system processing unit is connected with the multifunction control display unit and used for copying the formulated flight plan and carrying out assessment and dynamic modification on the flight plan. The invention converts the traditional signal processing scheme into a parallel processing scheme: one processing scheme is used for maintaining the traditional functions of formulating and executing the flight plan, and the other processing scheme is used for providing the dynamic modification and assessment functions; and flight personnel can effectively prepare and scientifically assess the change basis by dynamically modifying an assessment scheme, therefore, the invention can satisfy the changeful practical needs andimprove the flight safety and the flight operation effectiveness.

The invention discloses a method, system and device which realize multimedia calling operation, it is used to resolve problem that current WCDMA circuit field structure and multimedia calling operation can not make network provide additional functions which are relative with medium flow. The method includes: A. the load operation channel built when the MSC SERVER calls and the every part participating in multimedia calling operation build medium control command channel; B. MSC SERVER participates in medium arranging via said medium control command channel to accomplish the building of medium flow logical channel to realize the multimedia calling operation. By application of the invention, the MSC SERVER can participate in medium arranging, so the additional functions which are relative with medium flow can be provided for user.

An online key negotiation method and system suitable for the communication environment of the Internet of Things. The server monitors the connection request of the client through the registration port, and the client is preset with the digital certificate of the server; the server with a clear identity receives the client The information structure sent, the information structure contains the identity information of the client and the channel connection negotiation information; when the server receives the information structure, the server uses the preset client digital certificate or registered client ID to confirm the identity of the client ; The server feeds back the confirmation channel connection negotiation information to the client, and when the channel connection negotiation information fed back by the server is received by the client, a secure communication channel between the client and the server is established. The invention cancels the transmission of extended information; directly specifies the algorithm, no algorithm negotiation is performed; the content of the certificate is no longer transmitted, the number of communications in the handshake stage of the TLS protocol is reduced, and the negotiation efficiency of the encryption key in the communication of the Internet of Things is improved.

The invention discloses a resource polymerization method based on Agent; in computer and network technology wide application, resources scattered in a complex heterogeneous network become more and more, and the method can effectively gather the resources scattering in the distributed environment; the method comprises the following steps: configuring the resource polymerization method based on Agent in a distributed system; a task agent resolves and describes according to a user inputted task demand; a decision agent distributes the task to a corresponding service agent according to task description information; the service agent selects a resource agent in an Agent alliance to execute the task, a task execution result is returned to a user Agent, and displayed in a user interface. Communication between the service agent and the resource agent complies with an expansion contract net protocol, thus reducing communication load between Agents, and fast responding to the user task demand. The resource Agent can joint or withdraw from the Agent alliance, so dynamic characteristic is provided, thus enhancing resource polymerization method flexibility and scalability.

The present invention relates to a method for negotiating link capability information, a network device, and a communication system. The method includes: After a higher order optical channel data unit (ODU) link is established, a second node receives first higher order ODU link capability information supported by a first node at one end of the link, where the second node is located at the other end of the link; determines link capability information according to the first higher order ODU link capability information and second higher order ODU capability information that is supported by the second node; and sends the link capability information to the first node; or sends the second higher order ODU link capability information to the first node, so that the first node determines the link capability information according to the first higher order ODU link capability information and the second higher order ODU capability information. According to the embodiments of the present invention, efficiency of negotiating the higher order ODU link capability information is improved.
