Subject: [MSEC] TEK-CS mapping in MIKEY/SRTP

Hello,

I have the following issue: when negotiating the security parameters for 
an RTP session consisting of several SRTP streams having each of them 
its own SRTP master key, and assuming the SRTP master keys are sent as a 
sequence of TEKs, how are the TEKs in the KEMAC mapped to their 
corresponding CSs in case the KVs are null or of type From-To? (There 
seems to be nothing like a Policy # which helps mapping a crypto session 
to a policy.)

Thank you in advance.

Regards,
John
