PERC double media encryption for WebRTC 1.0 sender simulcast

Finance institutions have always needed enhanced security to protect their assets. Today that want to enjoy access to the cloud as well as new communication technologies like WebRTC. In parallel, the IETF created a new working group called Privacy Enhanced RTP Conferencing (PERC) that propose solutions to allow usage of media servers in the public cloud without compromising the security. This work is about implementing PERC's double encryption specifications in conjunction with WebRTC 1.0 sender simulcast. We are showing that the implementation of a few additional specifications, and an enhancement of the proposed Headers Extension mechanism allows for a viable double encryption for WebRTC 1.0 sender simulcast.
