Abstract Abstract
This document specifies the conventions for using the Merkle Tree This document specifies the conventions for using the Merkle Tree
Signatures (MTS) digital signature algorithm with the Cryptographic Signatures (MTS) digital signature algorithm with the Cryptographic
Message Syntax (CMS). The MTS algorithm is one form of hash-based Message Syntax (CMS). The MTS algorithm is one form of hash-based
digital signature. digital signature.
