Lecture 1. Introduction (Hash-Based Signatures)

Video lectures for Alfred Menezes's introductory course on hash-based
signatures including Leighton-Micali (LMS), eXtended Merkle (XMSS), and
SPHINCS+. These quantum-safe signature schemes have been standardized by
the Internet Engineering Task Force (IETF) and the National Institute of
Standards and Technology (NIST).

Topics covered: Post-quantum cryptography, the threat of quantum computers,
hash functions, hash-based signature schemes, Lamport signatures,
Leighton-Micali signatures, SPHINCS+.
