VSF Enhances RIST Main And Advanced Profiles To Add Generic Authentication

The Video Services Forum (VSF) has announced the release of the 2022 versions of the Reliable Internet Stream Transport (RIST) Protocol Specifications: Main Profile, TR-06-2, and Advanced Profile, TR-06-3.

The updates include support for EAP-SRP Authentication as well as the recently launched VSF EtherType. The updated documents are freely available from the VSF website for all to download and to use.

This update means that RIST can be used to securely create a multicast content distribution system which is completely open source and a free alternative to proprietary DRM systems. It uses vetted and known protection methods to keep content secure without the need for external keys or devices. Only authorized receivers will be able to decrypt the multicast content.

The new EAP-SRP authentication mechanism removes the need to generate and maintain complex SSL certificates. It also includes mechanisms to de-authorize receivers on-the-fly without disturbing the content. As well as enabling broadcasters and video content providers to create a multicast content distribution system, this authentication method can work as a standalone method for any industry and use case. It can also be encapsulated in both RIST Main Profile and RIST Advanced Profile.

The earlier revisions of RIST Main Profile used experimental EtherTypes. VSF has now registered its own EtherType with the IEEE and has revised the specification to use this value, thus ensuring ongoing co-existence with other protocols.
