t; I see your point and that it is out of scope for the document. However, I >>> feel the title and the abstract is then a bit misleading and should say that >>> this document discusses security architectures and cryptographic functions >>> for authentication/signing only?

Hi Carsten This document looks at a very specific deployment scenario where resource-constrained devices sign message objects. Therefore, it only documents the performance of ECDSA sign operation. I do think the numbers of Elliptic curve diffie-hellman key agreement are useful for the commun

Hi Mohit, One point that came up in the discussion in Prague was Diffie-Hellman performance. For a deployment that relies on symmetric keys for mutual authentication, it may be useful to do an (ECC) D-H key agreement to achieve forward security. I believe some numbers for that are available? I

Hi all The authors of the document believe that it is ready to move forward. During the previous last call we had already received support from several working group members. Based on the feedback during the previous last call, we removed the performance measurements of RSA key sizes smaller
