The IESG has received a request from the Bidirectional Forwarding Detection WG (bfd) to consider the following document: - 'Meticulous Keyed ISAAC for BFD Optimized Authentication' <draft-ietf-bfd-secure-sequence-numbers-22.txt> as Experimental RFC
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-c...@ietf.org mailing lists by 2025-08-18. Exceptionally, comments may be sent to i...@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-bfd-secure-sequence-numbers/ No IPR declarations have been submitted directly on this I-D.
