This note describes the eXtended Merkle Signature Scheme (XMSS), a
hash-based digital signature system. It follows existing descriptions
in scientific literature. The note specifies the WOTS+ one-time
signature scheme, a single-tree (XMSS) and a multi-tree variant
(XMSS^MT) of XMSS. Both variants use WOTS+ as a main building block.
XMSS provides cryptographic digital signatures without relying on the
conjectured hardness of mathematical problems. Instead, it is proven
that it only relies on the properties of cryptographic hash functions.
XMSS provides strong security guarantees and, besides some special
instantiations, is even secure when the collision resistance of the
underlying hash function is broken. It is suitable for compact
implementations, relatively simple to implement, and naturally resists
side-channel attacks. Unlike most other signature systems, hash-based
signatures withstand attacks using quantum computers.
