On the Security of Certificateless Signature Schemes
International Journal of Distributed Sensor Networks, 2013 Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

An Efficient Certificateless Signature Scheme [PDF]
, 2006 Certificateless public key cryptography (CLPKC) is a paradi-gm to solve the inherent key escrow problem suffered by identity-based cryptography (IBC). While certificateless signature is one of the most important security primitives in CLPKC, there are relatively few proposed schemes in the literature.

Certificateless signature scheme without random oracles [PDF]
Tongxin xuebao, 2015 The security of certificateless signature schemes can be proved under the random oracle model.However，any implementation of the random oracle may result in insecure schemes.Some certificateless signature schemes without random oracles are not secure ...

Generic Construction of Certificateless Signature
, 2004 To provide the binding between a user and his public key, traditional digital signature schemes use certificates that are signed by a trusted third party. While Shamir’s identity-based signature scheme can dispense with certificates, the key escrow of a user’s private key is inherent in the identity-based signature scheme.

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

An efficient certificateless undeniable signature scheme
International Journal of Computer Mathematics, 2014 Certificateless cryptography addresses the private key escrow problem in identity-based systems, while overcoming the costly issues in traditional public key cryptography. Undeniable signature schemes were proposed with the aim of limiting the public verifiability of ordinary digital signatures. The first certificateless undeniable signature scheme was
