Side-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 ...
EPFL2024Secure 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 ...
EPFL2024New SIDH Countermeasures for a More Efficient Key Exchange
Tako Boris Fouotsa, Andrea Basso
The Supersingular Isogeny Diffie-Hellman (SIDH) protocol has been the main and most efficient isogeny-based encryption protocol, until a series of breakthroughs led to a polynomial-time key-recovery attack. While some countermeasures have been proposed, th ...
Springer2023Extractable Witness Encryption for the Homogeneous Linear Equations Problem
Serge Vaudenay, Bénédikt Minh Dang Tran
Witness encryption is a cryptographic primitive which encrypts a message under an instance of an NP language and decrypts the ciphertext using a witness associated with that instance. In the current state of the art, most of the witness encryption construc ...
