Image encryption and decryption utilizing physical unclonable function-based key generator by Ta/WTiOx/Pt memristor array [PDF]

AIP Advances
In this work, an encryption and decryption system utilizing physical unclonable function (PUF) characteristics of the Ta/WTiOx/Pt memristor array as hardware-level security primitive is demonstrated.

On Bitcoin Security in the Presence of Broken Cryptographic Primitives [PDF]

, 2016
Digital currencies like Bitcoin rely on cryptographic primitives to operate. However, past experience shows that cryptographic primitives do not last forever: increased computational power and advanced cryptanalysis cause primitives to break frequently, and motivate the development of new ones.

Security Guidelines for Implementing Homomorphic Encryption

IACR Cryptology ePrint Archive
Fully Homomorphic Encryption (FHE) is a cryptographic primitive that allows performing arbitrary operations on encrypted data. Since the conception of the idea in [RAD78], it has been considered a holy grail of cryptography.

Foundations of Data Availability Sampling

IACR Commun. Cryptol.
Towards building more scalable blockchains, an approach known as data availability sampling (DAS) has emerged over the past few years. Even large blockchains like Ethereum are planning to eventually deploy DAS to improve their scalability. In a nutshell,

Parameter-Resident Cryptographic Material as an Unscoped Surface for Post-Quantum Migration: An Existence Proof and Audit Primitive

Computers
Federal post-quantum cryptography migration is scoped around three categories of cryptographic assets: libraries, protocols, and key stores. We argue that this scoping is incomplete.

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.
