Embodiment 1

[0058] Embodiment 1 of the present invention provides a method for using SIP signaling in a quantum secure communication system, such as figure 2 shown, including the following steps:

[0059] First, the system is initialized, and the corresponding relationship between the service terminal and the quantum gateway is configured in the SIP server;

[0060] Second, the SIP server receives the INVITE message sent by the quantum gateway of the calling party, rewrites the INVITE message according to the configuration, adds the quantum gateway ID of the calling party and the quantum gateway ID of the called party, and forwards the rewritten INVITE message to the called party quantum gateway;

[0061] Third, the called party quantum gateway receives the INVITE message, and obtains the quantum key shared with the calling party quantum gateway according to the quantum gateway ID in the INVITE message;

[0062] Fourth, after receiving the 200 OK message sent by the quantum gateway of ...

Embodiment 2

[0086] Embodiment 2 of the present invention provides a comprehensive access quantum gateway, which is used to connect various communication services between service terminals to the quantum security communication system, and realize secure communication between service terminals. The quantum gateway is composed of the access system and The key management system consists of two parts, the access system includes a business access module, protocol analysis module and signaling processing module; the key management system includes a key storage module and a data encryption and decryption module, such as Figure 5 As shown, the functions of each module are introduced as follows:

[0087] 1. Key storage module

[0088] Receive and store the quantum key generated by the QKD system, and send the corresponding quantum key to it according to the application of the data encryption and decryption module. The quantum key is stored according to the quantum gateway ID, and stored in the en...

Embodiment 3

[0100] Embodiment 3 of the present invention provides a quantum security communication system, which is used to realize the processing method of SIP signaling and service data in Embodiment 1. The system includes the calling party integrated access quantum gateway and the called party in Embodiment 2. Integrated access quantum gateway, SIP server, quantum key distribution (QKD) system; wherein the QKD system is used to provide a shared quantum key for the calling party integrated access quantum gateway and the called party integrated access quantum gateway.

[0101] Such as Figure 6 As shown, the present invention adds three types of equipment to the original business system: SIP server, QKD system, and integrated access quantum gateway. In a SIP system, a SIP server needs to exist and be connected to the classic network. Each service terminal corresponds to a QKD system and an integrated access quantum gateway. The business terminal is connected to the integrated access qu...

Abstract

The invention discloses a method applying SIP signaling to a quantum secure communication system. Aiming at the widely used SIP system, quantum gateway ID information is added on the basis that little SIP protocol instruction field is modified so that a quantum gateway can accurately identify and use a shared quantum secret key, encryption and decryption services can be provided for the business data of the SIP system, and dynamic integration of the SIP signaling business system and the quantum communication technology can be realized. Moreover, the invention further provides an integrated access quantum gateway and the quantum secure communication system which take the SIP signaling business as the basis, convert various business types into SIP signaling business, conduct encryption and decryption on each business data through the quantum secret key, and ensure the high safety of the business data transmission.

Description

technical field [0001] The invention relates to the technical field of quantum communication, in particular to a method for using SIP signaling in a quantum security communication system and a comprehensive access quantum gateway and quantum security communication system. Background technique [0002] Session Initiation Protocol SIP (Session Initiation Protocol) is an application-layer control protocol for multimedia communication on an IP network. It is used to create, modify and terminate a session process in which one or more participants participate. The SIP protocol can be used to initiate a session, and can also be used to invite members to join a session that has been established in other ways. [0003] The normal process from SIP session establishment to session termination is as follows: figure 1 Shown: [0004] 1. The user picks up the phone and initiates a call, and SIP terminal A sends an Invite request to the SIP server; [0005] 2. The SIP server forwards th...
