Hi again,
I am currently implementing EAP-NOOB on Zolertia Firefly boards
(https://zolertia.io/product/firefly/). The board provides hardware
acceleration for ECC operations. However, currently the API only
supports ECDHE with NIST P-256 and EAP-NOOB draft only mentions the
cryptosuite x25519 in Section 4.1.
I know that IETF likes the curve x25519, which has been specified
through the CFRG process. Besides that, I see that many other platforms
only support NIST P-256 in hardware. Thus, I wonder if it would be
possible to support NIST P-256 to the draft?
In this draft
(https://tools.ietf.org/html/draft-ietf-lwig-curve-representations-06) I
see that perhaps it is possible to use the code NIST P-256 for doing
x25519. However, I have no coding expertise in cryptographic encoding to
do that. Hence authors, do you want to support another curve?
Regards,
Eduardo Inglés.
