Certificateless signcryption [PDF]
Proceedings of the 2008 ACM symposium on Information, computer and communications security, 2008 Certificateless cryptography inherits a solution to the certificate management problem in public-key encryption from identity-based techniques, whilst removing the secret key escrow functionality inherent to the identity-based setting. Signcryption schemes achieve confidentiality and authentication simultaneously by combining public-key encryption and ...

Certificateless hybrid signcryption [PDF]
Mathematical and Computer Modelling, 2009 Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional signature-then-encryption approach. In this paper, we address a question whether it is possible to construct a hybrid signcryption scheme in the ...

Certificateless Searchable Encryption Scheme in Multi-User Environment
Cryptography, 2022 Searchable encryption technology enables users to access data that has been made publicly encrypted without divulging the original content. The majority of the currently available multi-user certificateless searchable encryption technologies are based on

A Lattice-Based Certificateless Traceable Ring Signature Scheme
Information, 2023 A ring signature (RS) scheme enables a group member to sign messages on behalf of its group without revealing the definite signer identify, but this also leads to the abuse of anonymity by malicious signers, which can be prevented by traceable ring ...

Reattack of a Certificateless Aggregate Signature Scheme with Constant Pairing Computations
The Scientific World Journal, 2014 A new attack against a novel certificateless aggregate signature scheme with constant pairing computations is presented. To enhance security, a new certificateless signature scheme is proposed first.
