Can we please have a new draft of draft-krawczyk-hkdf?

I am all for a common KDF.  Particularly where I am facing Yet Another 
KDF in IEEE 802.15.6!

Can we have a new draft posted as 00.txt has expired and is gone and I 
am in the 802.15.6 meetings right now and I want to bring this to the 
attention of the group?

Re: existing KDFs and their uses

Hi Hugo,

 

I just noticed NIST Special Publication 800-108, which, like HKDF, is based on the ideas of extract-then-expand.  It has HMAC and CMAC based options.  How does it fare in your view?  Especially, does have it security similar to HKDF?

 

Best regards,

 

Dan

David, this work that you are doing in compiling usage scenarios and existing KDFs is VERY useful. Hopefully, you can put it as a separate document. I am very interested to know if there is anything, except passwords, for which plain HKDF is insufficient.

I am interested in applications that require the KDF to generate regular random keys rather than some structured elements (such as group elements that require dedicated group-specific  techniques).

Thanks!

Hugo
