Explore a conference talk from PQCrypto 2023 focusing on hardware and side channel attacks in post-quantum cryptography. Delve into the vulnerabilities of Winternitz One-Time Signatures (WOTS) and how faulting them can lead to forged signatures in LMS, XMSS, or SPHINCS+ systems. Learn from experts Alexander Wagner, Vera Wesselkamp, Felix Oberhansl, Marc Schink, and Emanuele Strieder as they present their findings on this critical aspect of cryptographic security. Gain insights into the potential weaknesses of these signature schemes and understand the implications for post-quantum cryptography implementations.
