The Use of AES-192 and AES-256 in Secure RTP
RFC 6188, “The Use of AES-192 and AES-256 in Secure RTP”, is a Proposed Standard document published in March 2011 by D. McGrew. The canonical text is published by the RFC Editor.
Abstract
This memo describes the use of the Advanced Encryption Standard (AES) with 192- and 256-bit keys within the Secure RTP (SRTP) protocol. It details counter mode encryption for SRTP and Secure Realtime Transport Control Protocol (SRTCP) and a new SRTP Key Derivation Function (KDF) for AES-192 and AES-256. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
