Abstract

   This document specifies the conventions for using the the HSS/LMS
   hash-based signature algorithm with the Cryptographic Message Syntax
   (CMS).  The HSS/LMS algorithm is one form of hash-based digital
   signature; it is described in [HASHSIG].

1.  Introduction

   This document specifies the conventions for using the HSS/LMS hash-
   based signature algorithm with the Cryptographic Message Syntax (CMS)
   [CMS] signed-data content type.  The Leighton-Micali Signature (LMS)
   system provides a one-time digital signature that is a variant of
   Merkle Tree Signatures (MTS).  The Hierarchical Signature System
   (HSS) is built on top of the LMS system to efficiently scale for a
   larger  numbers of signatures.  The HSS/LMS algorithm is one form of
   hash-based digital signature, and it is described in [HASHSIG].  The
   HSS/LMS signature algorithm can only be used for a fixed number of
   signing operations.  The HSS/LMS signature algorithm uses small
   private and public keys, and it has low computational cost; however,
   the signatures are quite large.

1.1.  ASN.1

   CMS values are generated using ASN.1 [ASN1-B], using the Basic
   Encoding Rules (BER) and the Distinguished Encoding Rules (DER)
