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...
Quantum implementation of SLIM and its Grover cryptanalysis ÇILDIROĞLU, HASAN ÖZGÜR; Yayla, Oğuz (2025-10-01) We present a novel quantum implementation of SLIM, a lightweight 32/80-bit Feistel cipher. By inverting its Key addition-Substitution-Permutation (KSP) layers without ancillary qubits, we construct the full quantum circuit...
Dilithium-Based Verifiable Timed Signature Scheme Uslu, Erkan; Yayla, Oğuz (2025-01-04)
Families of sequences with good family complexity and cross-correlation measure Doğan, Kenan; ŞAHİN, MURAT; Yayla, Oğuz (2025-01-01) In this paper, we examine the pseudorandomness of a family of sequences with respect to two key measures: family complexity (f-complexity) and cross-correlation measure of order ℓ. Our study encompasses sequences over both...
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...
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...
Radix-3 NTT-Based Polynomial Multiplication for Lattice-Based Cryptography Hassan, Chenar; Yayla, Oğuz (2025-01-01) The lattice-based cryptography is considered a strong candidate amongst many other pro- posed quantum-safe schemes for the currently deployed asymmetric cryptosystems that do not seem to stay secure when quantum computers ...
Pairing-based Accountable Subgroup Multi-signatures with Verifiable Group Setup Ağırtaş, Ahmet Ramazan; Yayla, Oğuz (2025-01-01) An accountable subgroup multi-signature is a kind of multi-signature scheme in which any sub- group S of a group G of potential signers jointly sign a message m, ensuring that each member of S is accountable for the result...
