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 ...

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 ...

A Revocable Certificateless Signature Scheme [PDF]
Journal of Computers, 2014 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

Certificateless Generalized Signcryption
Physics Procedia, 2012 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.
