Secure and Efficient Cryptographic Algorithms in a Quantum World
Since the advent of internet and mass communication, two public-key cryptographic algorithms have shared the monopoly of data encryption and authentication: Diffie-Hellman and RSA. However, in the last few years, progress made in quantum physics -- and mor ...
EPFL2024Side-channel analysis of isogeny-based key encapsulation mechanisms and hash-based digital signatures
Current cryptographic solutions will become obsolete with the arrival of large-scale universal quantum computers. As a result, the National Institute of Standards and Technology supervises a post-quantum standardization process which involves evaluating ca ...
EPFL2024Making Classical (Threshold) Signatures Post-quantum for Single Use on a Public Ledger
Serge Vaudenay, Laurane Chloé Angélina Marco, Abdullah Talayhan
The Bitcoin architecture heavily relies on the ECDSA signature scheme which is broken by quantum adversaries as the secret key can be computed from the public key in quantum polynomial time. To mitigate this attack, bitcoins can be paid to the hash of a pu ...
