Re: [Lwip] I-D Action: draft-ietf-lwig-curve-representations-05.txt

Dear colleagues:

I slightly updated the draft to address Mohit Sethi's comment [1] on 
trade-offs between code reuse and computational efficiency. To this end, 
I added a little section (now Section 6) on "implementation 
considerations" - see[2].

As already suggested in [3], I did not give an explicit computational 
cost comparison, since this is highly device and application dependent 
and alone would not do justice other considerations that come into play 
when deciding on a crypto implementation strategy.

Best regards, Rene
