The SEED Cipher Algorithm and Its Use
with the Secure Real-Time Transport Protocol (SRTP)
Abstract
This document describes the use of the SEED block cipher algorithm in
the Secure Real-time Transport Protocol (SRTP) for providing
confidentiality for Real-time Transport Protocol (RTP) traffic and
for the control traffic for RTP, the Real-time Transport Control
Protocol (RTCP).
