Computational Monogamy of Entanglement and Non-Interactive Quantum Key Distribution
Alex B. Grilo, Giulio Malavolta, Michael Walter +1
Quantum key distribution (QKD) enables Alice and Bob to exchange a secret key over a public, untrusted quantum channel. Compared to classical key exchange, QKD achieves everlasting…
Cryptography from Lossy Reductions: Towards OWFs from ETH, and Beyond
Pouria Fallahpour, Alex B. Grilo, Garazi Muguruza +1
One-way functions (OWFs) form the foundation of modern cryptography, yet their unconditional existence remains a major open question. In this work, we study this question by explor…
Security of a secret sharing protocol on the Qline
Alex B. Grilo, Lucas Hanouz, Anne Marin
Secret sharing is a fundamental primitive in cryptography, and it can be achieved even with perfect security. However, the distribution of shares requires computational assumptions…
Quantum pseudoresources imply cryptography
Alex B. Grilo, Álvaro Yángüez
While one-way functions (OWFs) serve as the minimal assumption for computational cryptography in the classical setting, in quantum cryptography, we have even weaker cryptographic a…
A classical proof of quantum knowledge for multi-prover interactive proof systems
Anne Broadbent, Alex B. Grilo, Nagisa Hara +1
In a proof of knowledge (PoK), a verifier becomes convinced that a prover possesses privileged information. In combination with zero-knowledge proof systems, PoKs play an important…
Distributed Non-Interactive Zero-Knowledge Proofs
Alex B. Grilo, Ami Paz, Mor Perry
Distributed certification is a set of mechanisms that allows an all-knowing prover to convince the units of a communication network that the network's state has some desired proper…
