Blockchain‐Based Secure Data Sharing for IoT Devices Using Smart Contracts: A Systematic Review and Taxonomy

IET Blockchain, Volume 6, Issue 1, January/December 2026.
ABSTRACT The proliferation of Internet of Things (IoT) devices has created an urgent demand for secure, scalable and interoperable data‐sharing architectures. Centralized paradigms exhibit single points of failure, inadequate access control and limited transparency, rendering them structurally misaligned with the distributed nature of IoT deployments ...

An Efficient Heterogeneous Signcryption Scheme from Certificateless to Identity-based Cryptosystem

MATEC Web of Conferences, 2017
The heterogeneous signcryption can not only realize the confidentiality and un-forgeability of the information transmission between different public key cryptography environments, but also reduce the communication cost. The proposed scheme uses bilin-ear

Pairing‐Free Certificateless Searchable Public Key Encryption Scheme Resistant to Frequency Analysis for IIOT

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel lightweight certificateless public key authentication with keyword search (CPAEKS) scheme tailored for IIoT environments, effectively addressing data confidentiality and retrieval efficiency. The scheme resists frequency analysis attacks, removes reliance on bilinear pairings, and eliminates key escrow and certificate ...

Certificateless Public Key Cryptography: A Research Survey

International Journal of Security and Its Applications, 2016
Certificateless Public Key Cryptography is a scheme that provides security by avoiding the key escrow and eliminating the drawback of identity-based cryptography. Several certificateless models have been proposed to enhance the efficiency and overcome adversaries attacks. In this paper, we survey various public key encryption schemes on certificateless
