Hi All,
I would like to know the OID's to be used to signal AES256_CM(counter mode) encryption which uses SHA1-HMAC 32 and SHA1-HMAC80 for authentication. The H235.6 does not specify these ?
Thanks

Signaling AES256_CM encryption for SRTP in H245/h225
Re: Signaling AES256_CM encryption for SRTP in H245/h225
Just to clarify a bit more , I want to signal the SRTP capabilites in Termincal Capability Set and need to know the OID values to be used for AES256_CM with HMAC-32 and HMAC-80 for hashing.
Re: Signaling AES256_CM encryption for SRTP in H245/h225
H.235.6 is the industry's agreed standard which uses regular RTP with DH exchange.
2.16.840.1.101.3.4.1.42
DHE-RSA-AES256-SHA
Your looking at H.235.8 with SRTP which is not widely supported in H.323 and there is no OIDs defined for AES256. You are free to create you own as there is nothing defined.

Let me add that if you want to define something and make it a part of the standard, contact me privately and I'll discuss how to go about that.
