New Efficient Certificateless Signature Scheme [PDF]
In ubiquitous computing environment, how to implement security and trust among the users that connected to a network is a big problem. Digital signature provides authenticity, integrity and nonrepudiation to many kinds of applications in ubiquitous computing environment.

Performance analysis of certificateless signature for IKE authentication
Elliptic curve-based certificateless signature is slowly gaining attention due to its ability to retain the efficiency of identity-based signature to eliminate the need of certificate management while it does not suffer from inherent private key escrow ...

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

Provably secure certificateless aggregate signature scheme in wireless roaming authentication
Certificateless aggregate signature (CLAS) schemes have been widely applied in resource-constrained wireless mobile networks,because they could not only realize batch validation but also solve the certificate management and key escrow problems.It was ...

Cryptanalysis on Two Certificateless Signature Schemes
Certificateless cryptography has attracted a lot of attention from the research community, due to its applicability in information security. In this paper, we analyze two recently proposed certificateless signature schemes and point out their security flaws.

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 ...

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 ...

LIMA: Local and Lightweight Mutual Authentication for VANETs
This work presents LIMA, a lightweight local authentication protocol for VANETs. It is a SAE J2735 compliant certificateless vehicle authentication that eliminates traditional PKI dependencies while providing geographic zone‐based security and time‐based attribute control.
