The IESG has approved the following document: - 'Meticulous Keyed ISAAC for BFD Optimized Authentication' (draft-ietf-bfd-secure-sequence-numbers-27.txt) as Experimental RFC
This document is the product of the Bidirectional Forwarding Detection Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and Ketan Talaulikar. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-bfd-secure-sequence-numbers/ 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. Personnel The Document Shepherd for this document is Reshad Rahman. The Responsible Area Director is Ketan Talaulikar.
