A Context‐Aware Secure Two‐Tier Account‐Based Retail Central Bank Digital Currency Framework: A Case Study of Tanzania

IET Information Security, Volume 2026, Issue 1, 2026.
Central bank digital currencies (CBDCs) are increasingly being explored as a means to enhance financial inclusion, reduce transaction costs and modernise payment systems. However, their design and implementation pose significant challenges, particularly in emerging economies such as Tanzania, where security risks, infrastructural constraints and ...

Research on Lattice-Based Cryptographic Algorithms [PDF]

Jisuanji gongcheng
The security of classical public-key cryptosystems, which operate based on the computational intractability of integer factorization and discrete logarithm problems, is profoundly threatened by the rapid development of quantum computing.

Permanent Anchors and Adaptive Throughput: Extending Proof‐of‐Access Consensus to Resolve the Blockchain Trilemma

IET Information Security, Volume 2026, Issue 1, 2026.
Contemporary distributed ledgers face an inherent trilemma when attempting to simultaneously optimize three critical properties: transaction throughput (measured in transactions per second [TPS]), network security, and node decentralization. Current decentralized storage platforms such as Filecoin encounter constraints in managing peak transaction ...

Experimental authentication of quantum key distribution with post-quantum cryptography

npj Quantum Information, 2021
Quantum key distribution (QKD) can provide information theoretically secure key exchange even in the era of quantum computers. However, QKD requires the classical channel to be authenticated, the current method for which is pre-sharing symmetric keys ...

MA‐LCPPA: A Multi‐Aggregator Lattice‐Based Conditional Privacy‐Preserving Authentication Scheme for Scalable and Quantum‐Secure VANETs

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...

Post Quantum Cryptography (PQC) Signatures Without Trapdoors

CoRR
Some of our current public key methods use a trap door to implement digital signature methods. This includes the RSA method, which uses Fermat's little theorem to support the creation and verification of a digital signature. The problem with a back-door is that the actual trap-door method could, in the end, be discovered.

When classical encryption fails: A non-invasive post-quantum security layer for medical image transfers

Informatics in Medicine Unlocked
Quantum computing threatens the long-term security of widely deployed public-key cryptography used to protect medical image transfer. The Digital Imaging and Communications in Medicine (DICOM) standard is the dominant format and protocol suite for ...
