ECC‐PoARV: A Lightweight Blockchain Architecture With Rotational Validation for Scalable IoT Networks

IET Blockchain, Volume 6, Issue 1, January/December 2026.
To address the incompatibility of traditional blockchains with the Internet of Things (IoT), this paper introduces ECC‐PoARV, a novel architecture that integrates elliptic curve cryptography with a resilient proof‐of‐authority consensus featuring rotational validation.

Provably-Secure (Chinese Government) SM2 and Simplified SM2 Key Exchange Protocols

The Scientific World Journal, 2014
We revisit the SM2 protocol, which is widely used in Chinese commercial applications and by Chinese government agencies. Although it is by now standard practice for protocol designers to provide security proofs in widely accepted security models in order

DDMIA: Distributed Dynamic Mutual Identity Authentication for Referrals in Blockchain-Based Health Care Networks

IEEE Access, 2022
Patients go to multiple healthcare providers for treatment, and their health data is generally distributed among providers. The distributed health data and the decentralized health care system structure make it ideal for blockchain-based health ...

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 ...

SKE2SG: A Secure Key Establishment Scheme for Smart Grid Cyber‐Physical Systems Based on Elliptic Curve Cryptography

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

Group structure of elliptic curves over ℤ/Nℤ

Journal of Mathematical Cryptology
We characterize the possible groups E(Z∕NZ)E\left({\mathbb{Z}}/N{\mathbb{Z}}) arising from elliptic curves over Z∕NZ{\mathbb{Z}}/N{\mathbb{Z}} in terms of the groups E(Fp)E\left({{\mathbb{F}}}_{p}), with pp varying among the prime divisors of NN.

Accelerating Baby-step Giant-step Algorithm for Solving ECDLP Using Elliptic Divisibility Sequences

Transactions on Cryptographic Hardware and Embedded Systems
The elliptic curve discrete logarithm problem (ECDLP) is the foundation of the security of elliptic curve cryptography. The baby-step giant-step (BSGS) method is a generic deterministic algorithm, based on a space-time tradeoff, to solve the discrete ...
