Digital signatures to ensure the authenticity and integrity of synthetic DNA molecules
… our efforts to solve this problem by embedding digital signatures in DNA molecules synthesized in the laboratory. We encounter several challenges that we do not face in the digital world. These challenges arise primarily from the fact that changes to a physical DNA molecule can affect its …

Security Assessment of a Machine Learning Approach to Generate and Validate Digital Signatures
… to improve the cyber security of systems such as Digital Signatures, hashing, watermarking, and encryption among others. Digital Signatures are a cryptographic technique used to verify the authenticity and integrity of digital messages or documents. Digital Signatures use a combination of hashing …

From pen and paper to pixels. – Usability and User Acceptance of Digital Signatures: A Customer-Centric Study in Hungarian SMEs
Hungary ranks 22nd in the EU Digital Economy and Society Index, with only 53.2% of SMEs demonstrating basic digital intensity, compared to 57.7% across the EU (Digital Decade Country Report 2024: Hungary, 2024). This dissertation investigates the adoption of a foundation tool, digital signature, …

zk-Sigstore: System for Anonymous Certificate-Based Software Signing
… the problem, many repositories have implemented digital signatures for packages to verify the contributor’s identity, but with limited success due to well-documented usability issues surrounding key management. The digital signature primitive itself also does not provide an answer to which …

A secure architecture for electronic check processing
… a cryptographic protocol for the transmission of digital checks using cryptographic building blocks like public key encryption and digital signatures.
-
On symbolic analysis of cryptographic protocols
… the framework to include protocols that use digital signatures as well. In the process of expanding the framework, we identify a flaw in the framework's use of UC ideal functionality FKE. We also identify issues that arise when combining FKE with the current formulation of ideal signature …

Password-less two-factor authentication using scannable barcodes on a mobile device
… existing technologies, asymmetric cryptography, digital signatures, and biometric authentication. Simulated user testing shows promising results, suggesting that registration can be completed in just over thirty seconds, and authentication in just over two seconds. An analysis of this project’s …

Privacy Enhancing Protocols using Pairing Based Cryptography
… (IBE). We define a desirable property of digital signatures, blindness, and present new IBE constructions which incorporate this property. Blindness is a desirable feature from a privacy perspective as it allows an individual to obscure elements such as personal details in the data it …

Code-Based Digital Signature Schemes: Construction, Cryptanalysis and Theoretical Foundations
In recent decades, numerous code-based digital signature schemes following the hash&sign paradigm have been proposed, often turning out to be insecure and demonstrating that the cryptographic community still seems far from a satisfactory solution in this area. The first major question we pose in …

An architecture study of a Byzantine-resilient processor using authentication
… authentication protocol which provides the digital signatures used to verify the origin and contents of messages is a public-key protocol using 32-bit Cyclic Redundancy Codes (CRC's) to encode the message with 32-bit modular inverse key pairs to sign and authenticate the CRC. An interactive …

A scalable Byzantine fault tolerant secure domain name system
… origin authentication by means of cryptographic digital signatures. However, the proposed extension suffers from some security flaws. In this thesis, we discuss the security problems of DNS and its security extension. As a solution, we present the design and implementation of a …

Randomized algorithms for reliable broadcast
… that allows the players to compute (public-key) digital signatures. * Our protocols work even if the source of randomness is a "somewhat random" source (also called a Santha-Vazirani source). The price we pay is a decreased fault-tolerance. Our second result is the design of a compiler that …
