Review of Cryptographic Schemes applied to Remote Electronic Voting systems: remaining challenges and the upcoming post-quantum paradigm

Open Mathematics, 2018
The implantation of Remote Electronic Voting (REV) systems to Electoral Processes is happening at a slower pace than anticipated. One of the relevant factors explaining that reality is the lack of studies about the Cryptographic Schemes and Primitives ...

SoK: On Shallow Weak PRFs

IACR Transactions on Symmetric Cryptology
A growing number of advanced cryptographic protocols and constructions rely on symmetric primitives known as weak pseudo-random functions (wPRFs). These functions differ significantly from traditional PRFs: they operate in constrained models where ...

Lower Bounds on Signatures from Symmetric Primitives [PDF]

, 2019
We show that every construction of one-time signature schemes from a random oracle achieves black-box security at most $2^{(1+o(1))q}$, where $q$ is the total number of oracle queries asked by the key generation, signing, and verification algorithms ...

OPTIMIZED REPRESENTATIONS IN CRYPTOGRAPHIC PRIMITIVES

, 2022
This work focuses on optimization of cryptographic primitives both in theory and in applications. From a theoretical point of view, it addresses the problem of speeding up the polynomial multiplication used in Post-Quantum cryptosystems such as NTRU and McEliece. In particular, the latter extensively uses Galois fields whose elements can be represented

Automated Generation of Fault-Resistant Circuits

Transactions on Cryptographic Hardware and Embedded Systems
Fault Injection (FI) attacks, which involve intentionally introducing faults into a system to cause it to behave in an unintended manner, are widely recognized and pose a significant threat to the security of cryptographic primitives implemented in ...

Cryptographic primitives based on compact knapsack problem

Journal of Information Security and Applications
In the present paper, we extend previous results of an id scheme based on compact knapsack problem defined by one equation. We present a sound three-move id scheme based on compact knapsack problem defined by an integer matrix. We study this problem by providing attacks based on lattices.

AI-driven adaptive adversaries and the erosion of cryptographic trust in public key systems

Journal of Analytical Science and Technology
This paper examines the erosion of Public Key Cryptography (PKC) security under adaptive adversarial optimisation driven by artificial intelligence. The problem addressed is the growing mismatch between algorithm-centric cryptographic security models and
