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 ...

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 ...

Self-Generated-Certificate Public Key Cryptography and Certificateless Signature / Encryption Scheme in the Standard Model [PDF]
Certificateless Public Key Cryptography (CL-PKC) enjoys a number of features of Identity-Based Cryptography (IBC) while without having the problem of key escrow.

Data outsourcing improves the scalability of large‐scale storage systems but introduces risks related to data tampering and unverifiable ownership claims. Existing provable data possession (PDP) schemes often incur substantial cryptographic overhead and primarily focus on data integrity.

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
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

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.

Certificateless public key cryptography
A criptografia de chave pública sem certificado (certificateless) é uma alternativa ao modelo convencional de criptografia assimétrica, pois a autenticação da chave pública ocorre implicitamente durante a execução dos protocolos, sem a necessidade de ...
