Security Vulnerabilities of Four Signature Schemes From NTRU Lattices and Pairings

open access: yesIEEE Access, 2020
Certificateless cryptography solves the certificate management problem in public-key cryptography and the key-escrow problem in identity-based cryptography. Xie et al. proposed a certificateless signature scheme using NTRU lattices.

Cryptanalysis of Two Signature Schemes for IoT-Based Mobile Payments and Healthcare Wireless Medical Sensor Networks

open access: yesIEEE Access, 2020
Certificateless cryptography does not require any certificate for the public key authentication and users' public keys are transmitted with ciphertext/signatures or by making them available in the IoT-based public directory in a proper way.

Fail-Stop Ring Signature Scheme Based on Certificateless Cryptosystem [PDF]

open access: yesJisuanji gongcheng, 2020
Fail-stop group signature schemes can prevent opponents with strong compute power from counterfeiting signatures,and thereby implement privacy protection for users.On the basis of the fail-stop group signature scheme,this paper designs a fail-stop ring ...

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

open access: yesIET 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 ...
