Certificateless signature scheme without random oracles
The security of certificateless signature schemes can be proved under the random oracle model.However,any implementation of the random oracle may result in insecure schemes.Some certificateless signature schemes without random oracles are not secure ...

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 ...

Towards quantum‐safe blockchain: Exploration of PQC and public‐key recovery on embedded systems
This paper addresses the need for quantum‐safe blockchain solutions specifically for embedded systems by integrating Post‐Quantum Cryptography (PQC) into blockchain frameworks. We propose a quantum‐secure blockchain architecture using NIST‐standardized PQC algorithms, finding Falcon‐512 to be optimal for embedded environments due to its security and ...
