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...
