Title : The Use of the Secure Real-time Transport Protocol (SRTP) in Store-and-Forward Applications
Author(s) : R. Blom, et al.

This memo describes the use of so called store-and-forward
cryptographic transforms within the Secure Real-time Transport
Protocol (SRTP). The motivation is to support use cases when two
end-points communicate via one (or more) store-and-forward
middleboxes that are not fully trusted to access the media content.
One of the main aspects of the transform is to make the
confidentiality and message authentication independent of the RTP
header. Another central aspect is to make identification of the
cryptographic context (keys etc.) independent of RTP transport
parameters. Besides the security of the end-points, also trust
assumptions regarding the store-and-forward middleboxes are
addressed.
