On the Theory and Practice of Modern Secure Messaging
Billions of people now have conversations daily over the Internet. A large portion of this communication takes place via secure messaging protocols that offer "end-to-end encryption'" guarantees and resilience to compromise like the widely-used Double Ratc ...
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 ...
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 ...
2023Approximation Algorithms for Allocation and Network Design
In this thesis, we give new approximation algorithms for some NP-hard problems arising in resource allocation and network design. As a resource allocation problem, we study the Santa Claus problem (also known as the MaxMin Fair Allocation problem) in which ...
EPFL2023Specific Gestalt principles cannot explain (un)crowding
Michael Herzog, Oh-Hyeon Choung, Einat Rashal
The standard physiological model has serious problems accounting for many aspects of vision, particularly when stimulus configurations become slightly more complex than the ones classically used, e.g., configurations of Gabors rather than only one or a few ...
