This paper surveys the literature on certificateless encryption schemes. In particular, we
examine the large number of security models that have been proposed to prove the security …

With the digitalization of various industries, the combination of cloud computing and the
industrial Internet of Things (IIoT) has become an attractive data processing paradigm …

Certificateless cryptography inherits a solution to the certificate management problem in
public-key encryption from identity-based techniques, whilst removing the secret key escrow …

To ensure the security and privacy of the patient's health status in the wireless body area
networks (WBANs), it is critical to secure the extra-body communication between the smart …

In this paper we revisit the security models of certificateless signatures and propose two new
constructions which are provably secure in the random oracle model. We divide the potential …

Existing conditional anonymous authentication protocols to secure the group communication
in VANETs (Vehicular Ad hoc Networks) render challenges such as dynamically updating …

Certificateless public-key cryptography (CL-PKC) schemes are particularly robust against
the leakage of secret information stored on a trusted third party (TTP). These security …

Certificateless aggregate signature (CLAS) schemes reduce the trust on the key generation
center of identity-based signatures and thus partially address the inherent key escrow issue …

Certificateless public key cryptosystem solves both the complex certificate management
problem in the public key cryptosystem based on the PKI and the key escrow issue in the …

Certificateless public key signcryption scheme is an important cryptographic primitive in
cryptography. Barbosa and Farshim proposed a certificateless signcryption scheme …
