Authors, Thanks for your replies. We have updated our files to reflect these changes. 1. We have an additional question about the use of the <tt> element in the XML file. It was used 3 times in the document as follows: <tt>hss_public_key</tt> structure. <tt>xmss_public_key</tt> structure. <tt>xmssmt_public_key</tt> structure. Note that in the HTML and PDF outputs, <tt> yields fixed-width font. In the text output, there is no change. Please review to ensure this appears as desired. 2. We have updated the block quote in Section 3 to include more text per your request. Please review. The current files are available here: https://www.rfc-editor.org/authors/rfc9802.xml https://www.rfc-editor.org/authors/rfc9802.txt https://www.rfc-editor.org/authors/rfc9802.pdf https://www.rfc-editor.org/authors/rfc9802.html Diff files: https://www.rfc-editor.org/authors/rfc9802-auth48diff.html https://www.rfc-editor.org/authors/rfc9802-diff.html https://www.rfc-editor.org/authors/rfc9802-rfcdiff.html (side by side) Note that it may be necessary for you to refresh your browser to view the most recent version. Daniel: please review the files and let us know if any additional updates are needed or if you approve the RFC for publication.

Please review and let us know if any updates are needed. Original: This document specifies algorithm identifiers and ASN.1 encoding formats for the stateful hash-based signature (HBS) schemes Hierarchical Signature System (HSS), eXtended Merkle Signature Scheme (XMSS), and XMSS^MT, a multi-tree variant of XMSS.

Please review and let us know if you prefer otherwise. Note that the text file will continue to display XMSS^MT, but the HTML and PDF will display MT in superscript. --> 4) <!-- [rfced] Please review some questions regarding the following text: a) For ease of the reader, may we reformat this text as follows? Original: Usual backup and restore strategies when using a stateless signature scheme (e.g. SLH-DSA) are to duplicate private keying material and to operate redundant signing devices or to store and safeguard a copy of the private keying material such that it can be used to set up a new signing device in case of technical difficulties.

Original: This document uses a lot of text from similar documents [SP800208], ([RFC3279] and [RFC8410]) as well as [I-D.ietf-lamps-rfc8708bis]. Thanks go to the authors of those documents.

For consistency throughout the document, may we abbreviate all instances of "object identifier" to "OID" after first expansion? b) We note different uses of the following term. For clarity, may we lowercase "certificate authorities" so that it does not appear to reference the abbreviation "CA"? Certification Authority (CA) certificates Certificate Authorities c) FYI - We expanded the following abbreviation upon first use per Section 3.6 of RFC 7322 ("RFC Style Guide"). Please review carefully to ensure correctness: Internet of Things (IoT) --> 8) <!-- [rfced] We have changed all <artwork> elements in this document to <sourcecode>.

The current list of preferred values for "type" is available at <https://www.rfc-editor.org/rpc/wiki/doku.php?id=sourcecode-types><https://www.rfc-editor.org/rpc/wiki/doku.php?id=sourcecode-types>. If the current list does not contain an applicable type, feel free to suggest additions for consideration. Note that it is also acceptable to leave the "type" attribute not set. --> 9) <!-- [rfced] Please review whether any of the notes in this document should be in the <aside> element. It is defined as "a container for content that is semantically less important or tangential to the content that surrounds it" (https://authors.ietf.org/en/rfcxml-vocabulary#aside). --> 10) <!-- [rfced] Please review the "Inclusive Language" portion of the online Style Guide <https://www.rfc-editor.org/styleguide/part2/#inclusive_language><https://www.rfc-editor.org/styleguide/part2/#inclusive_language> and let us know if any changes are needed. Updates of this nature typically result in more precise language, which is helpful for readers.

If an author is no longer available, there are several remedies available as listed in the FAQ (https://www.rfc-editor.org/faq/). You and you coauthors are responsible for engaging other parties (e.g., Contributors or Working Group) as necessary before providing your approval. Planning your review --------------------- Please review the following aspects of your document: * RFC Editor questions Please review and resolve any questions raised by the RFC Editor that have been included in the XML file as comments marked as follows: <!-- [rfced] ... --> These questions will also be sent in a subsequent email. * Changes submitted by coauthors Please ensure that you review any changes submitted by your coauthors. We assume that if you do not speak up that you agree to changes submitted by your coauthors. * Content Please review the full content of the document, as this cannot change once the RFC is published. Please pay particular attention to: - IANA considerations updates (if applicable) - contact information - references * Copyright notices and legends Please review the copyright notice and legends as defined in RFC 5378 and the Trust Legal Provisions (TLP – https://trustee.ietf.org/license-info). * Semantic markup Please review the markup in the XML file to ensure that elements of content are correctly tagged. For example, ensure that <sourcecode> and <artwork> are set correctly. See details at <https://authors.ietf.org/rfcxml-vocabulary><https://authors.ietf.org/rfcxml-vocabulary>. * Formatted output Please review the PDF, HTML, and TXT files to ensure that the formatted output, as generated from the markup in the XML file, is reasonable. Please note that the TXT will have formatting limitations compared to the PDF and HTML.

The parties include: * your coauthors * rfc-edi...@rfc-editor.org<mailto:rfc-edi...@rfc-editor.org> (the RPC team) * other document participants, depending on the stream (e.g., IETF Stream participants are your working group chairs, the responsible ADs, and the document shepherd). * auth48archive@rfc-editor.org<mailto:auth48archive@rfc-editor.org>, which is a new archival mailing list to preserve AUTH48 conversations; it is not an active discussion list: * More info: https://mailarchive.ietf.org/arch/msg/ietf-announce/yb6lpIGh-4Q9l2USxIAe6P8O4Zc * The archive itself: https://mailarchive.ietf.org/arch/browse/auth48archive/ * Note: If only absolutely necessary, you may temporarily opt out of the archiving of messages (e.g., to discuss a sensitive matter). If needed, please add a note at the top of the message that you have dropped the address. When the discussion is concluded, auth48archive@rfc-editor.org<mailto:auth48archive@rfc-editor.org> will be re-added to the CC list and its addition will be noted at the top of the message. You may submit your changes in one of two ways: An update to the provided XML file — OR — An explicit list of changes in this format Section # (or indicate Global) OLD: old text NEW: new text You do not need to reply with both an updated XML file and an explicit list of changes, as either form is sufficient. We will ask a stream manager to review and approve any changes that seem beyond editorial in nature, e.g., addition of new text, deletion of text, and technical changes. Information about stream managers can be found in the FAQ. Editorial changes do not require approval from a stream manager.
