w

Definitions:

  In XMSS, the length of a Winternitz chain. A single Winternitz chain uses log2(w) bits from the hash or checksum.
Sources:
NIST SP 800-208

  In LMS, the number of bits from the hash or checksum used in a single Winternitz chain. The length of a Winternitz chain is 2w. (Note that using a Winternitz parameter of w = 4 in LMS would be comparable to using a parameter of w = 16 in XMSS.)
