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?  
It would be useful to include them in order to motivate the use of forward secure key agreement.

Grüße, Carsten

We also added performance measurements of ECDSA sign operation on ARM 32-bit platforms. Additionally, we improved the text on the need for a random number generator, more guidance on choosing the right platform, and why larger flash memory size is needed for firmware updates. We also removed some extraneous text from the background section. Any further comments are welcome.
