Proof in a Bottle: Long-Lived Verifiable Secret Sharing via Pre-Quantum Commitment and Immutable Ledger Binding
Markus Jakobsson, Keir Finlow-Bates
Traditional secret sharing techniques such as Verifiable Secret sharing (VSS) are vulnerable to quantum attacks by a Cryptographically Relevant Quantum Computer (CRQC) running Shor…
The Cost of Quantum Resistance: A Hash-Based Commit-Reveal Alternative for Minimizing Blockchain Infrastructure Overhead
Keir Finlow-Bates, Markus Jakobsson, Hossein Siadati
The transition to post-quantum cryptography in blockchain systems such as Bitcoin and Ethereum is often framed as a purely cryptographic problem. In practice, it also presents sign…
Breaking ECDSA with Two Affinely Related Nonces
Jamie Gilchrist, William J. Buchanan, Keir Finlow-Bates
The security of the Elliptic Curve Digital Signature Algorithm (ECDSA) depends on the uniqueness and secrecy of the nonce, which is used in each signature. While it is well underst…
ECDSA Cracking Methods
William J. Buchanan, Jamie Gilchrist, Keir Finlow-Bates
The ECDSA (Elliptic Curve Digital Signature Algorithm) is used in many blockchain networks for digital signatures. This includes the Bitcoin and the Ethereum blockchains. While it…
