But I believe not all comments from ~2 weeks ago (see > attached) have been addressed. E.g. use of “symmetric algorithm” and “shared > secret key” (as opposed to using variations of the same term). [mj] I looked at the use of the word “shared” in the draft, and there are four instances.I believe in two of those cases it is being used to indicate that the key has to be shared between the sender the receiver, i.e. as an adjective to the word key. Do you have another way to suggest similar text? The two other instances where it is still being used, in Section 3 with this line: The result is computed, using a shared key, on the sequence number. and then later in the same section with this line: Upon receiving the BFD Control packet, the receiver decrypts the ciphertext using the same provisioned shared key to produce the received sequence number. we could change it to say “shared symmetric key”. > Also, section 4 headline is still “Impact of using a hash”, but the text has > been changed (hash -> cyphertext) here > <https://www.ietf.org/rfcdiff?url2=draft-ietf-bfd-secure-sequence-numbers-07>. [mj]. Agree. We can change the header to say “Impact of using ciphertext in-lieu of sequence number”. Would these changes address the remaining comments? > > Regards, > Reshad. > > From: Rtg-bfd <rtg-bfd-boun...@ietf.org <mailto:rtg-bfd-boun...@ietf.org>> on > behalf of Sonal Agarwal <sagarwa...@gmail.com <mailto:sagarwa...@gmail.com>> > Date: Monday, March 8, 2021 at 2:40 PM > To: <rtg-bfd@ietf.org <mailto:rtg-bfd@ietf.org>> > Subject: Re: I-D Action: draft-ietf-bfd-secure-sequence-numbers-08.txt > > Hi all, > > Version 8 of the draft addresses all Shepherd comments. > > Regards, > Sonal. > > > On Mon, Mar 8, 2021 at 11:16 AM <internet-dra...@ietf.org > <mailto:internet-dra...@ietf.org>> wrote: >> >> A New Internet-Draft is available from the on-line Internet-Drafts >> directories. >> This draft is a work item of the Bidirectional Forwarding Detection WG of >> the IETF. >> >> Title : Secure BFD Sequence Numbers >> Authors : Mahesh Jethanandani >> Sonal Agarwal >> Ashesh Mishra >> Ankur Saxena >> Alan DeKok >> Filename : draft-ietf-bfd-secure-sequence-numbers-08.txt >> Pages : 6 >> Date : 2021-03-08 >> >> Abstract: >> This document describes a security enhancement for the sequence >> number used in BFD control packets.
