Technical Summary
This document describes a new BFD Optimized Authentication Mode,
Meticulous Keyed ISAAC Authentication. This mode can be used to
authenticate BFD packets with less CPU time cost than using MD5 or
SHA1, with the tradeoff of decreased security. This mechanism cannot
be used to signal state changes, but it can be used to maintain a
session in the the Up state.
Working Group Summary
The WG consensus represents the strong consensus of a few
individuals. The document got WG attention during the initial
phase of progression through the WG and at one point the
proposal in the document did change significantly (i.e., use
of the ISAAC mechanism). During the later phases in the WG, the
document did not receive further significant inputs/reviews
due to lack of active implementation interest from major vendors.
Thereafter, it was picked up for WGLC where it received some
further reviews and support for publication as part of the
set of 3 related documents that extend BFD authentication.
There were no controversies or threat of appeals.
Document Quality
There are no known implementations or plans for implementation.
The work started as Proposed Standard and then was the track
was changed by the WG to Experimental as the WG believes
implementation experience was required to ensure maturity as
a Proposed Standard.
The document has undergone review from YANG doctors (when the
module was part of draft-ietf-bfd-optimizing-authentication
and a fresh review is requested on this document), as well as
early directorate reviews from RTG, SEC and OPS areas.
