Hi Zhen
Thanks for the feedback.
We have previously ported Brian Gladman's byte-oriented AES code
http://www.gladman.me.uk/AES <https://github.com/abhay/gladman-aes> to
the same 8-bit platform.
We were able to perform AES encryption and decryption with very little
amount of RAM consumption (< ~2kB) and minimal execution time.
Hope this info is useful. We look forward to further feedback.
Thanks

Hi Mohit ,
Nice draft with a lot of reference data
one quick question: do you have any data around AES/tinyAES, and DTLS
memory footprint?
Many thanks,
Zhen

Dear all,
We have uploaded the next version of our draft documenting the
implementation experiences of public-key cryptography on 8-bit
micro-controllers. The draft is available here:
https://tools.ietf.org/html/draft-aks-lwig-crypto-sensors-01
In this updated version, we have included the implementation results from
the performance analysis of Ed25519 (the crypto forum research group is
currently specifying the recommended parameters) signature generation on the
same 8-bit micro-controller.
The informational document also provides design patterns and guidelines for
ensuring integrity protection and freshness of messages that might be
helpful when deploying such devices in practice.
We look forward to your feedback. We also request the chairs to allocate a
short slot (10/12 mins) for presenting this updated version.
Thanks

Abstract:
This memo describes challenges associated with securing smart object
devices in constrained implementations and environments. The memo
describes a possible deployment model suitable for these
environments, discusses the availability of cryptographic libraries
for small devices, presents some preliminary experiences in
implementing small devices using those libraries, and discusses
trade-offs involving different types of approaches.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
