MATRIX ALGORITHMS OF ENCRYPTIC PROTECTION OF INFORMATION AND EXCHANGE OF ENCRYPTION KEY

Ìнформаційні технології в освіті, 2010
The algorithms of the exchange of encryption keys between users of computer networks and cryptographic protection of information transmitted over open communications channels. The algorithm is based a modified asymmetric protocol Diffie-Hellman (DH). The

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.

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.

Cryptanalysis of Selected ARX-Based Block Ciphers

Vietnam Journal of Computer Science
The security of digital communication and information systems is mostly dependent on block ciphers. ARX-based ciphers are widely used due to their simplicity and efficiency.

The least primitive roots mod p

Journal of Mathematical Cryptology
Let p>1p\gt 1 be a large prime number, and let ε>0\varepsilon \gt 0 be a small number. The established unconditional upper bounds of the least primitive root u≠±1,v2u\ne \pm 1,{v}^{2} in the prime finite field Fp{{\mathbb{F}}}_{p} have exponential ...

Quantum Cryptographic Primitives

The main motivation of this thesis is the uncertain panorama of cybersecurity risks and threats, accentuated by the arrival of the quantum computer. This type of computer is completely disruptive, since its operation is governed by quantum mechanical phenomena.
