Random Data and Its Cryptographic Applications Yavuzyiğit, Ayşe Eda; Yayla, Oğuz (2026-01-01) Random sequence construction represents fundamental components of modern cryptographic systems. The quantitative assessment of randomness relies upon rigorous statistical testing methodologies, establishing statistical ran...
Blockchain-Based Carbon Footprint Management Pekel, Umut; Yayla, Oğuz (2026-01-01) This paper introduces a novel approach to managing carbon footprints using blockchain technology to integrate these footprints intrinsically into the attributes of products, akin to their price. In contrast to conventional...
A Computational Study on Sobol' Sequences Tokmak, Bahri; Uğur, Ömür (2025-10-11)
Spatio-temporal crop yield prediction using time-varying copula and actuaries climate index Yavrum, Cem; Kestel, Sevtap Ayşe; Garrido, José (2025-09-10) Climate anomalies pose significant threats to agricultural productivity and food security by severely disrupting crop yields. While weather conditions at harvest time are important, extreme climate anomalies occurring du...
PIR Schemes from nD-Cyclic and nD-Constacyclic Codes and Their Monomial Equivalence Yılmaz, Burcu Ecem (2025-07-07)
Dilithium-Based Verifiable Timed Signature Scheme Uslu, Erkan; Yayla, Oğuz (2025-01-04)
Threshold Structure-Preserving Signatures with Randomizable Key A Ğ Irtas, Ahmet Ramazan; Ç Elik, Emircan; Kocaman, Sermin; Sulak, Fatih; Yayla, Oğuz (2025-01-01) Digital signatures confirm message integrity and signer identity, but linking public keys to identities can cause privacy concerns in anonymized settings. Signatures with randomizable keys can break this link, preserving v...
Distributed Verifiable Random Function with Compact Proof Ağırtaş, Ahmet Ramazan; Özer, Arda Buğra; Saygı, Zülfükar; Yayla, Oğuz (2025-01-01) Verifiable Random Functions (VRFs) are cryptographic primitives that generate unpredictable randomness along with proofs that are verifiable, a critical requirement for blockchain applications in decentralized finance, onl...
Weak Enforcement of Boundary Conditions for Maxwell’s Problem Using the Linked Lagrange Multiplier Method Codina, Ramon; Türk, Önder (2025-01-01) In this study, we propose a finite element approximation of Maxwell’s problem with the prescription of essential boundary conditions in a weak way that is based on a linked Lagrange multiplier approach. We consider an augm...
Compartment-Based and Hierarchical Threshold Delegated Verifiable Accountable Subgroup Multi-signatures Ağırtaş, Ahmet Ramazan; Yayla, Oğuz (2025-01-01) In this paper, we study the compartment-based and hierarchical delegation of signing power of the verifiable accountable subgroup multi-signature (vASM). ASM is a multi-signature in which the participants are accountable f...
UOV-Based Verifiable Timed Signature Scheme Uslu, Erkan; Yayla, Oğuz (2025-01-01) Verifiable Timed Signatures (VTS) are cryptographic primitives that enable the creation of a signature that can only be retrieved after a specific time delay, while also providing verifiable evidence of its existence. This...
Efficient Batch Post-quantum Signatures with Crystals Dilithium Türe, Nazlı Deniz; Cenk, Murat (2025-01-01) Digital signatures ensure authenticity and secure communication. They are used to verify the integrity and authenticity of signed documents and are widely utilized in various fields such as information technologies, financ...
32-bit and 64-bit CDC-7-XPUF Implementations on a Zynq-7020 SoC Yayla, Oğuz; Yılmaz, Yunus Emre (2025-01-01) Physically (or Physical) Unclonable Functions (PUFs) are basic and useful primitives in designing cryptographic systems. PUFs are designed to facilitate device authentication, secure boot, firmware integrity, and secure co...
Modal analysis in mixed finite element methods Türk, Önder (2024-09-09)
Insurance Fraud Detection via Clustering-Based Fuzzy Classification On Noisy Unbalanced Datasets Koç, Oğuz; Başer, Furkan; Kestel, Sevtap Ayşe (2024-09-09) One of the most important challenges in overcoming the unsystematic risks in the insurance industry is fraud detection as the expenses associated with it can be disastrous, and can increase loading on reserves and premiums...
Assessing the applicability of the Actuaries Climate Index within weather derivatives framework Yavrum, Cem; Kestel, Sevtap Ayşe (2024-09-04) The global climate change has emerged as one of the most complex and pressing challenges confronting humanity. With the impact of climate change intensifying, a growing number of industries, such as agriculture, insurance,...
Analysis of the threshold dependence of degree related indices in weighted random graphs and complex networks Işlak, Ümit; Yıldırım Külekci, Bükre (2024-06-26)
Least-squares finite element formulations of Steklov eigenvalue problems Bertrand, Fleurianne; Türk, Önder (2024-06-14)
Approximation of a Laplace-Steklov eigenvalue problem by finite and boundary element methods Türk, Önder (2024-01-11)
Single Secret Leader Election in Proof-of-Stake Blockchains: A Concise Review Fettuh, Tegrid; Yayla, Oğuz (2024-01-01) Proof-of-stake (PoS) consensus mechanisms are a scalable, energy-efficient alternative to Proof-of-Work (PoW) in blockchain technology. Leader election, which selects the node to propose the next block, is key to PoS syste...
