Public-Key Encryption with Quantum Keys
In the framework of Impagliazzo's five worlds, a distinction is often made between two worlds, one where public-key encryption exists (Cryptomania), and one in which only one-way functions exist (MiniCrypt). However, the boundaries between these worlds can ...
Cham2023Security 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 ...
EPFL2023DFAulted: Analyzing and Exploiting CPU Software Faults Caused by FPGA-Driven Undervolting Attacks
Mirjana Stojilovic, Dina Gamaleldin Ahmed Shawky Mahmoud, David Dervishi
Field-programmable gate arrays (FPGAs) combine hardware reconfigurability with a high degree of parallelism. Consequently, FPGAs offer performance gains and power savings for many applications. A recent trend has been to leverage the hardware versatility o ...
2022Secret Key Generation Using Short Blocklength Polar Coding Over Wireless Channels
This paper investigates the problem of secret key generation from correlated Gaussian random variables in the short blocklength regime. Short blocklengths are commonly employed in massively connected IoT sensor networks in 5G and beyond wireless systems. P ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Towards Efficient LPN-Based Symmetric Encryption
Serge Vaudenay, Sonia Mihaela Bogos, Dario Korolija, Thomas Locher
Due to the rapidly growing number of devices that need to communicate securely, there is still significant interest in the development of efficient encryption schemes. It is important to maintain a portfolio of different constructions in order to enable a ...
Springer International Publishing2021Complete 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 ...
2021Power Yoga: Variable-Stretch Security of CCM for Energy-Efficient Lightweight IoT
Damian Vizár, Reza Reyhanitabar, Emiljano Gjiriti
The currently ongoing NIST LWC project aims at identifying new standardization targets for lightweight authenticated encryption with associated data (AEAD) and (optionally) lightweight cryptographic hashing. NIST has deemed it important for performance and ...
RUHR-UNIV BOCHUM, HORST GORTZ INST IT-SICHERHEIT2021Classical Misuse Attacks on NIST Round 2 PQC: The Power of Rank-Based Schemes
Serge Vaudenay, Loïs Evan Huguenin-Dumittan
The US National Institute of Standards and Technology (NIST) recently announced the public-key cryptosystems (PKC) that have passed to the second round of the post-quantum standardization process. Most of these PKC come in two flavours: a weak IND-CPA vers ...
