Embodiment 1

[0060] This embodiment provides an SRTP capability negotiation method, which is used in conference terminals. Such as figure 2 As shown, the SRTP capability negotiation method includes the following steps:

[0061] Step S11: The second conference terminal receives a first call request sent by the first conference terminal, where the first call request carries a first attribute parameter used to indicate the SRTP capability currently supported by the first conference terminal.

[0062] In this embodiment, the conference terminal in the conference system is described by taking two conference terminals as an example. That is, the first conference terminal and the second conference terminal conduct a video conference, and the audio and video data of the video conference are transmitted between the first conference terminal and the second conference terminal.

[0063] The second conference terminal receives the first call request sent by the first conference terminal, that is, the first...

Embodiment 2

[0075] This embodiment provides an SRTP capability negotiation method, which is used in conference terminals. Such as image 3 As shown, the SRTP capability negotiation method includes the following steps:

[0076] Step S21: The second conference terminal receives a first call request sent by the first conference terminal, where the first call request carries a first attribute parameter used to indicate the SRTP capability currently supported by the first conference terminal.

[0077] In the transmission of audio and video data of the video conference in this embodiment, the description of the interactive information in the session process is carried out by means of the Session Initiation Protocol (SIP); in addition, combined with the Session Description Protocol (Session Description Protocol) , Referred to as SDP for short) describes the media capabilities.

[0078] Among them, the interaction of audio and video data based on SRTP requires SIP to negotiate the SRTP encryption algor...

Embodiment 3

[0101] This embodiment provides an SRTP capability negotiation method, which is used in conference terminals. Such as Figure 4 As shown, the SRTP capability negotiation method includes the following steps:

[0102] Step S31: The first conference terminal sends a first call request to the second conference terminal. The first call request carries a first attribute parameter that indicates the SRTP capability currently supported by the first conference terminal. The first call request is used to request and The second conference terminal performs the first SRTP capability negotiation.

[0103] The first conference terminal queries the locally supported SRTP capabilities, and sends one or more of the SRTP capabilities to the second conference terminal in the form of a first attribute parameter to conduct the first SRTP capability negotiation.

[0104] For the relevant details of the first attribute parameter, please refer to step S11 of Embodiment 1, which will not be repeated here.

Abstract

The invention discloses an SRTP capability negotiation method and a conference terminal. The method comprises the following steps: a second conference terminal receives a first call request sent by afirst conference terminal; the second conference terminal queries whether the SRTP capability supported by the first conference terminal at present is supported locally based on a first attribute parameter in the first call request, so as to perform primary SRTP capability negotiation; and if not, the second conference terminal sends a secondary SRTP capability negotiation request to the first conference terminal, wherein the secondary SRTP capability negotiation request is used for requesting to perform secondary SRTP capability negotiation with the first conference terminal. Related SRTP capability negotiation is performed by a request / response model; if the negotiation fails, it can be negotiated again through a secondary negotiation mechanism to ensure the effectiveness of the final SRTP capability, reduce the failure rate of the SRTP capability negotiation, and avoid the situation of negotiation failure due to SRTP capability updating or failure of all negotiation in the primary SRTP capability negotiation process.

Description

Technical field [0001] The present invention relates to the technical field of information security, in particular to an SRTP capability negotiation method and conference terminal. Background technique [0002] In a video conference system, audio and video data need to be transmitted in real time. In the prior art, audio and video data are usually transmitted in real time based on the Real-time Transport Protocol (RTP), which specifies the packaging format of each frame of data in detail, which can meet most application requirements. [0003] However, with the increasing importance of network information security issues, application requirements for encrypting audio and video data in a video conference system have been inevitable. At this time, the Secure Real-time Transport Protocol (SRTP) as a media encryption protocol came into being. SRTP provides a framework for encrypting and authenticating RTP streams, and provides encryption algorithms and authentication algorithms. SRTP...
