Thanks a bunch René! Mohit, you can trust René on this. I'd rather make the change before the SEC DIR review. Can you please make it and republish?
Thanks in advance : ) Pascal -----Original Message----- From: Mohit Sethi [mailto:[email protected]] Sent: jeudi 21 septembre 2017 16:16 To: Rene Struik <[email protected]>; Pascal Thubert (pthubert) <[email protected]>; [email protected] Cc: [email protected] Subject: Re: [6lo] FW: I-D Action: draft-ietf-6lo-ap-nd-03.txt Hi Rene, Thanks for pointing out. This is a case me trying to be too efficient in updating the draft. This is rather critical and will be fixed in the next iteration. It would be good to know if others have any opinion on the mode of Ed25519. --Mohit On 09/21/2017 05:00 PM, Rene Struik wrote: > Hi Pascal: > > I had a quick glance at the document, just to see which type of crypto > was being recommended. {For now, I did not review anything else yet.} > > The document includes the option of using Curve25519, as defined in > RFC 7748, for signing.
