Technical Summary
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. This
specification applies to the Internet X.509 Public Key infrastructure
(PKI) when those digital signatures are used in Internet X.509
certificates and certificate revocation lists.
Working Group Summary
There is support in the LAMPS WG for this document. All comments that
were raised during WG Last Call were resolved. There was little controversy,
and suggested improvements were readily accepted by the authors.
Document Quality
The ASN.1 module compiles without errors.
This document specified the conventions for using the HSS/LMS, XMSS, and
XMSS^MT signature algorithms in X.509 certificates. HSS/LMS is specified
in RFC 8554, which is already in the downref registry. XMSS and XMSS^MT
are specified in RFC 8391, which is not yet in the downref registry.
Personnel
The Document Shepherd for this document is Russ Housley. The Responsible
Area Director is Deb Cooley.
