Hi, Russ
I have gone through your document. well but the question here is what is it IETF considering as combined mdoe algorithms.
Like you said out of all the algorithms that i know CMM is is the only one which is not patented and the basical algorithms used in that are already approved by NIST. So i am trying to get more information before i consider this.

Thanks for your reply. We are developing AISIC solutions for Security applications and as part of this we implement Cryptographic algorithms in the hardware.
ESP v2 talks about the combined mode algorithms and couldn't get any information about the algorithms that we must support for this.
Can you throw some light on this.

In a separate I-D, I plan to post a specification for using AES-CCM.
For those that are interested, you can learn more about AES-CCM at http://csrc.nist.gov/encryption/modes/proposedmodes/ccm/ccm.pdf.

What about the combined modes that AES support?
