Cryptanalysis and improvement of an efficient certificateless signature scheme

open access: yes, 2008
In traditional digital signature schemes, certificates signed by a trusted party are required to ensure the authenticity of the public key. In Asiacrypt 2003, the concept of certificateless signature scheme was introduced.

A Distributed and Decentralized Certificateless Framework for Reliable Shared Data Auditing for FOG-CPS Networks

open access: yesIEEE Access, 2023
FOG computing enhances communication efficiency by processing data at the network’s edge. In many critical infrastructure (CI) networks, user entities outsource data to the FOG server, but the reliability of the data is a concern.

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

open access: yesIET 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 ...

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

open access: yesMATEC 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

Practical Certificateless Aggregate Signatures From Bilinear Maps [PDF]

open access: yes, 2008
Aggregate signature is a digital signature with a striking property that anyone can aggregate n individual signatures on n different messages which are signed by n distinct signers, into a single compact signature to reduce computational and storage ...
