Zero-Knowledge Proof (ZKP) Authentication for Offline CBDC Payment System Using IoT Devices

CoRR
Central Bank Digital Currency (CBDCs) are becoming a new digital financial tool aimed at financial inclusion, increased monetary stability, and improved efficiency of payment systems, as they are issued by central banks. One of the most important aspects is that the CBDC must offer secure offline payment methods to users, allowing them to retain cash ...

Erasure‐Coded Sharding and Proof‐of‐Storage for Practical Blockchain Trilemma Balance

IET Blockchain, Volume 6, Issue 1, January/December 2026.
The proposed storage‐first blockchain framework resolves the blockchain trilemma by synergistically combining decentralised storage, zero‐knowledge proofs and sharded proof‐of‐storage consensus. Empirical evaluation demonstrates a peak throughput of 2800 transactions per second with low latency and strong Byzantine fault tolerance, while substantially ...

Lightweight Mutual Authentication in VANETs: A Software‐Defined Networking and Edge Computing Approach

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

MPC‐Facilitated Adaptive Security Framework for BFT Protocols

IET Information Security, Volume 2026, Issue 1, 2026.
The growing use of blockchain and distributed systems requires Byzantine fault tolerant (BFT) protocols that remain secure under dynamic adversaries. However, existing BFT protocols often rely on static assumptions and lack clear mechanisms to detect and remove malicious or denial‐of‐service (DoS) nodes during execution.

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 ...
