Abstract:
Hash-based signature (HBS) schemes are an efficient method of guaranteeing the authenticity of data in a post-quantum world. The stateful schemes LMS and XMSS and the stateless scheme SPHINCS+ are already standardised or will be in the near future. The Winternitz one-time signature (WOTS) scheme is one of the fundamental building blocks used in all these HBS standardisation proposals.We present a new fault injection attack targeting WOTS that allows an adversary to forge signatures for ar...     »
