Concurrency and Computation: Practice and Experience, Volume 38, Issue 19, October 2026.ABSTRACTThis work presents a privacy‐preserving remote healthcare system that integrates blockchain technology with a root seed‐based pseudonymization mechanism and lightweight cryptographic controls. Addressing the privacy risks of public ledgers and the limited computational resources of medical IoT devices, the proposed system focuses strictly on ...

Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting
Small, Volume 22, Issue 46, 18 August 2026.Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...

BUFFing signature schemes beyond unforgeability and the case of post-quantum signatures [PDF]
, 2023 Modern digital signature schemes can provide more guarantees than the standard notion of (strong) unforgeability, such as offering security even in the presence of maliciously generated keys, or requiring to know a message to produce a signature for it ...

Aggregate, Volume 7, Issue 2, February 2026.Solvent‐driven reversible “crystal to crystal” transformation of copper(I)‐iodine clusters with significant difference of luminescent color and quantum yields is reported. The differences before and after this transformation may be related to more efficient thermally activated delayed fluorescence (TADF) achieved by cluster 1 through space charge ...

Journal of Critical Infrastructure Policy, Volume 7, Issue 1, Spring/Summer 2026.ABSTRACT The infiltration of counterfeit, fraudulent, and suspect items into civil nuclear supply chains, notably within power generation and medical isotope production, poses severe safety and security threats. The ever‐increasing growth in nuclear installations (70 power plants are under construction and another 100 are in the planning stage) and the

A Unified Framework For Quantum Unforgeability
, 2021 50 pages, 5 figuresIn this paper, we continue the line of work initiated by Boneh and Zhandry at CRYPTO 2013 and EUROCRYPT 2013 in which they formally define the notion of unforgeability against quantum adversaries specifically, for classical message ...

IET Blockchain, Volume 6, Issue 1, January/December 2026.ABSTRACT Bidding transactions are widely used in scenarios such as government procurement and corporate tendering. However, while traditional blockchain achieves transparency in transactions, it also poses a risk of sensitive information such as bidder identity, quotation, and time being leaked, thereby undermining the fairness and compliance of ...

A Review of Offline Blockchain Transaction Systems
IET Blockchain, Volume 6, Issue 1, January/December 2026.Blockchain systems currently rely on constant network connectivity, which limits their utility in remote areas, during network outages or cyber attacks. This paper presents the first systematic study on offline blockchain implementations, analyzing their security and privacy challenges.
