Shufflecake: Plausible Deniability for Multiple Hidden Filesystems on Linux
Elia Anzuoni, Tommaso Gagliardoni
We present Shufflecake, a new plausible deniability design to hide the existence of encrypted data on a storage medium making it very difficult for an adversary to prove the existe…
Quantum Indistinguishability for Public Key Encryption
Tommaso Gagliardoni, Juliane Krämer, Patrick Struck
In this work we study the quantum security of public key encryption schemes (PKE). Boneh and Zhandry (CRYPTO'13) initiated this research area for PKE and symmetric key encryption (…
Can you sign a quantum state?
Gorjan Alagic, Tommaso Gagliardoni, Christian Majenz
Cryptography with quantum states exhibits a number of surprising and counterintuitive features. In a 2002 work, Barnum et al. argue that these features imply that digital signature…
Unforgeable Quantum Encryption
Gorjan Alagic, Tommaso Gagliardoni, Christian Majenz
We study the problem of encrypting and authenticating quantum data in the presence of adversaries making adaptive chosen plaintext and chosen ciphertext queries. Classically, secur…
Quantum Security of Cryptographic Primitives
Tommaso Gagliardoni
We call quantum security the area of IT security dealing with scenarios where one or more parties have access to quantum hardware. This encompasses both the fields of post-quantum…
Computational Security of Quantum Encryption
Gorjan Alagic, Anne Broadbent, Bill Fefferman +3
Quantum-mechanical devices have the potential to transform cryptography. Most research in this area has focused either on the information-theoretic advantages of quantum protocols…
General Impossibility of Group Homomorphic Encryption in the Quantum World
Frederik Armknecht, Tommaso Gagliardoni, Stefan Katzenbeisser +1
Group homomorphic encryption represents one of the most important building blocks in modern cryptography. It forms the basis of widely-used, more sophisticated primitives, such as…
The Fiat-Shamir Transformation in a Quantum World
Özgür Dagdelen, Marc Fischlin Tommaso Gagliardoni
The Fiat-Shamir transformation is a famous technique to turn identification schemes into signature schemes. The derived scheme is provably secure in the random-oracle model against…
