An efficient RSA-based certificateless signature scheme

Journal of Systems and Software, 2012
Until now, the only known construction of certificateless signature scheme is mainly based on the rather new and untested assumptions related to bilinear maps. But the implementations of pairings are more time-consuming than exponentiation operator in a RSA group.

A new provably secure certificateless short signature scheme

Computers and Mathematics With Applications, 2011
Certificateless public key cryptography simplifies the complex certificate management in the traditional public key cryptography and resolves the key escrow problem in identity-based cryptography. In 2007, Huang et al.

Certificateless Aggregate Signature Scheme

2010 International Conference on E-Business and E-Government, 2010
This paper puts forward a secure construction of certificateless aggregate signature scheme using bilinear maps. The security of our scheme is based on the infeasibility of the Computational Diffie-Hellman problem and is formally proven in the strongest security model of certificateless aggregate signature schemes.

Certificateless Concurrent Signature Scheme

2008 The 9th International Conference for Young Computer Scientists, 2008
Certificateless public key cryptography was introduced to remove the use of certificate to ensure the authentication of the user's public key in the traditional certificate-based public key cryptography and overcome he key escrow problem in the identity-based public key cryptography.

Cryptanalysis and improvement of an efficient certificateless signature scheme

Journal of Communications and Networks, 2008
In traditional digital signature schemes, certificates signed by a trusted party are required to ensure the authenticity of the public key. In Asiacrypt 2003, the concept of certificateless signature scheme was introduced.

Efficient Certificateless Proxy Signature Scheme

International Journal of Foundations of Computer Science, 2016
A proxy signature scheme allows a proxy signer to sign messages on behalf of an original signer within a given context. We propose a certificateless proxy signature (CLPS) scheme, and prove it's security under a stronger security model. Although some good results were achieved in speeding up the computation of pairing function in recent years, it is ...

Efficient Certificateless Signature Schemes

2007
Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity based cryptography, the notion of certificateless public key cryptography was introduced. In this paper, to construct an efficient certificateless signature (CLS) scheme, we present a new approach compactly and ...
