Hi All,

Would request the list to provide feedback on the revised draft.

Our assumption is that there are lot many applications which can get 
benefitted by
Selective Encryption approach and any standardized mechanism will be more
useful than proprietary implementations.

Thanks & Regards,

Revised IETF Draft - Support for Selective Encryption in SRTP

Hi All,

We have re-submitted ietf draft on support for selective encryption in 
SRTP - this draft
is enhanced based on the feedback received from the mailing list. Its 
available at:
 
http://www.ietf.org/internet-drafts/draft-smahajan-srtp-selective-encryption-01.txt

Would request the members on the list to go through the draft and provide 
their valuable feedback.

Summary of changes:
1) Included some detailed description of "Selective Encryption" with 
examples of both kind of selective
     encryption - based on content type and frame type
2) Real life examples of usage of selective encryption
3) 2 methods to support Selective Encryption in SRTP - overloaded MKI bit 
and additional parameter
     in SRTP to indicate selective encryption
4) Enhanced "Security Consideration" section to warn misuse of selective 
encryption
