Improving Physically Unclonable Functions’ Performance Using Second-Order Compensated Measurement

Information
In this paper, we study the performance of second-order compensated measurement to generate a multi-bit response in physically unclonable functions (PUFs).

Post-quantum signature algorithms based on the hidden discrete logarithm problem [PDF]

Computer Science Journal of Moldova, 2018
New options of the hidden discrete logarithm problem are proposed as cryptographic primitive of the post-quantum signature algorithms. Two signature schemes using computations in finite non-commutative algebras with associative multiplication operation

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.

Efficient Length Doubling From Tweakable Block Ciphers

IACR Transactions on Symmetric Cryptology, 2017
We present a length doubler, LDT, that turns an n-bit tweakable block cipher into an efficient and secure cipher that can encrypt any bit string of length [n..2n − 1].

On the composable security of weak coin flipping [PDF]

Quantum
Weak coin flipping is a cryptographic primitive in which two mutually distrustful parties generate a shared random bit to agree on a winner via remote communication. While a stand-alone secure weak coin flipping protocol can be constructed from noiseless

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.
