Certificateless Generalized Signcryption
AbstractGeneralized Signcryption is a fresh cryptographic primitive that not only can obtain encryption and signature in a single operation, but also provide encryption or signature model alone when needed. This paper proposed a formal definition of certificateless generalized signcryption(CLGSC), then provide the security model of CLGSC.

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 ...

Security-Mediated Certificateless Cryptography [PDF]
We introduce the notion of security-mediated certificateless (SMC) cryptography. This allows more lightweight versions of mediated cryptography while maintaining the ability for instantaneous revocation of keys. Moreover, our solutions avoid key escrow, which has been used in all previous mediated cryptography algorithms. We provide a model of security

A Revocable Certificateless Signature Scheme [PDF]
Certificateless public key cryptography (CLPKC), with properties of no key escrow and no certificate, has received a lot of attention since its invention. However, how to revoke a user in certificateless cryptosystem still remains a problem: the existing solutions are not practical for use due to either a costly mediator or enormous computation (secret
