[VOIPSEC] Secure Real-time Transport Protocol (SRTP)

[Doug Bundgaard]

Hi, there was some problem getting this posted last week, but better late than 
never...

Nortel is actively implementing SRTP and appropriate key management protocols 
into our products.  We view this as an important component of a secure 
solution. 

We do believe that MIKEY is the right protocol for SRTP key management, but 
more work needs to be done for MIKEY to be widely deployable.  As you might be 
aware, the SDP key management framework to carry MIKEY messages is still in 
IESG review at the IETF. Nortel engineers are contributing to a new MIKEY mode 
that will help resolve many deployment issues (please see the minutes of the 
MSEC meeting at IETF-62, and feel free to participate in the discussion in the 
MSEC mailing list).  Other work to make MIKEY more efficient is also underway 
in the MSEC working group. 

In addition to our IETF work, Nortel engineers are working with ATIS PRQC to 
introduce SRTP as the preferred protocol for media encryption.  Similarly, 
TR41.4, with Nortel contributions, has just finished drafting an standard about 
to go to ballot (IS 811-A). This standard has SRTP as the protocol for media 
encryption.
