Security in the Presence of Quantum Adversaries
With the looming threat of large-scale quantum computers, a fair portion of recent cryptographic research has focused on examining cryptographic primitives from the perspective of a quantum adversary. Shor's 1994 result revealed that quantum computers can ...
EPFL2023EOS: Efficient Private Delegation of zkSNARK Provers
Alessandro Chiesa, Yinuo Zhang
Succinct zero knowledge proofs (i.e. zkSNARKs) are powerful cryptographic tools that enable a prover to convince a verifier that a given statement is true without revealing any additional information. Their attractive privacy properties have led to much ac ...
Berkeley2023Temperature Impact on Remote Power Side-Channel Attacks on Shared FPGAs
Mathias Josef Payer, Mirjana Stojilovic, Ognjen Glamocanin, Hajira Shafqat Bazaz
To answer the growing demand for hardware acceleration, Amazon, Microsoft, and many other major cloud service providers have included field-programmable gate arrays (FPGAs) in their datacenters. However, researchers have shown that cloud FPGAs, when shared ...
2023Thwarting Malicious Adversaries in Homomorphic Encryption Pipelines
Homomorphic Encryption (HE) enables computations to be executed directly on encrypted data. As such, it is an auspicious solution for protecting the confidentiality of sensitive data without impeding its usability. However, HE does not provide any guarante ...
EPFL2023Complete Practical Side-Channel-Assisted Reverse Engineering of AES-Like Ciphers
Andrea Felice Caforio, Subhadeep Banik, Muhammed Fatih Balli
Public knowledge about the structure of a cryptographic system is a standard assumption in the literature and algorithms are expected to guarantee security in a setting where only the encryption key is kept secret. Nevertheless, undisclosed proprietary cry ...
2021SafetyPin: Encrypted Backups with Human-Memorable Secrets
Henry Nathaniel Corrigan-Gibbs
We present the design and implementation of SafetyPin, a system for encrypted mobile-device backups. Like existing cloud-based mobile-backup systems, including those of Apple and Google, SafetyPin requires users to remember only a short PIN and defends aga ...

USENIX ASSOC2020Multiquadratic Rings and Walsh-Hadamard Transforms for Oblivious Linear Function Evaluation
The Ring Learning with Errors (RLWE) problem has become one of the most widely used cryptographic assumptions for the construction of modern cryptographic primitives. Most of these solutions make use of power-of-two cyclotomic rings mainly due to its simpl ...
IEEE2020Determining the Core Primitive for Optimally Secure Ratcheting
Serge Vaudenay, Muhammed Fatih Balli
After ratcheting attracted attention mostly due to practical real-world protocols, recently a line of work studied ratcheting as a primitive from a theoretic point of view. Literature in this line, pursuing the strongest security of ratcheting one can hope ...
2020Bidirectional Asynchronous Ratcheted Key Agreement with Linear Complexity
Serge Vaudenay, Fatma Betül Durak
Following up mass surveillance and privacy issues, modern secure communication protocols now seek more security such as forward secrecy and post-compromise security. They cannot rely on an assumption such as synchronization, predictable sender/receiver rol ...
