The problem of nonlinear substitution generation (S-boxes) is investigated in many related works symmetric key cryptography. In particular, the strength ciphers to linear cryptanalysis directly nonlinearity substitution. addition being highly nonlinear, S-boxes must be random, i.e., not contain hidden mathematical constructs that facilitate algebraic cryptanalysis. such substitutions a complex combinatorial optimization problem. Probabilistic algorithms are used solve it, for instance...

In the rapidly evolving field of digital asset management, centralized and decentralized global registries have become essential tools for organizing, tracking, distributing assets. However, existing systems often face challenges regarding security, censorship resistance, interoperability, customizability, scalability. This research paper aims to address these gaps by proposing a novel registry system based on blockchain technology non-fungible tokens (NFTs). The makes several key...

The S-box is a key component of modern ciphers, determining the quality and performance cryptographic algorithms in which it applied. Many constructions for synthesizing high-quality S-boxes have been established, those based on Galois fields theory—for example, Nyberg construction applied AES algorithm—are particularly important. An integral affine transformation, used to improve avalanche correlation properties S-box. In this paper, new approach adopted transformations quaternary matrices...

The motion of bedload particles is diffusive and occurs within at least three scale ranges: local, intermediate global, each which with a distinctly different diffusion regime. However, these regimes, extensions the ranges boundaries between them remain to be better defined quantified. These issues are explored using Lagrangian model saltating grains over uniform fixed bed. combines deterministic particle dynamics stochastic characteristics such as probability distributions step lengths...

In this paper, we develop the theoretical provisions of symmetric cryptographic algorithms based on polynomial residue number system for first time. The main feature proposed approach is that when reconstructing method undetermined coefficients, multiplication performed not found base numbers but arbitrarily selected polynomials. latter, together with pairwise coprime residues class system, serve as keys algorithm. Schemes and examples implementation developed encryption algorithm are...

Two double-spend attack strategies on a proof-of-stake consensus are considered. For each strategy, the probability of its success is obtained, which depends network parameters and number confirmation blocks. These results can be used to define how many blocks vendor should wait after correspondent transaction before sending goods or services.

Distributed Denial of Service (DDoS) attacks are still one the major cybersecurity threats and focus much research on developing DDoS attack mitigation detection techniques. Being able to model can help researchers develop effective countermeasures. Modeling attacks, however, is not an easy task because modern huge simulating them would be impossible in most cases. That’s why use tools like network simulators for modeling attacks. Simulation a widely used technique networking research, but...
