Insecurity of a Certificateless Signature Scheme

2018 International Conference on Advances in Computing, Communication Control and Networking (ICACCCN), 2018
Certificateless signature scheme delivers the certificate problem and solve the key escrow problem inherit in the public key cryptography and identity based cryptography. Xiong et al suggested a certificateless aggregate signature scheme and proved that their CLS scheme is protected against all adversaries present in the network.

On the Security of a Certificateless Signature Scheme

Applied Mechanics and Materials, 2014
Certificateless public key cryptography eliminates inherent key escrow problem in identity-based cryptography, and does not yet requires certificates as in the traditional public key infrastructure. Recently, Yu et al. propose a new certificateless signature scheme and their scheme offers shorter system parameters and higher computational efficiency ...

On the security of a certificateless signature scheme

2010 2nd International Conference on Signal Processing Systems, 2010
Certificateless public key cryptography (CLPKC) eliminates certificate management in traditional public key infrastructure and solves the problem of the key escrow in identity-based cryptography. Certificateless signature is one of the most important primitives in CLPKC. Many certificateless signature (CLS) schemes have been proposed these years. For a

Certificateless Directed Signature Scheme

2011 7th International Conference on Wireless Communications, Networking and Mobile Computing, 2011
In directed signature schemes, only a designated verifier can both verify the signature by himself, and also interact with a signer to prove the (in)validity of a given signature intended to him. In this paper, we propose the first certificateless directed signature scheme which is provably secure in the random oracle model.

A Provably Secure Certificateless Blind Signature Scheme

2009 Fifth International Conference on Information Assurance and Security, 2009
Blind signature is very important technology in secure e-commerce. Certificateless public key cryptography avoids the using of certificate in certificate-based public key signature scheme and removes key escrow in ID-based signature scheme. In this paper we introduce the notion of blind signature into certificateless public key cryptography and propose

An Attack on a Certificateless Signature Scheme. [PDF]

IACR Cryptol. ePrint Arch., 2006
This paper demonstrates that a certificateless signature scheme recently proposed by Gorantla and Saxena is insecure. It is shown that an adversary who replaces the public key of a signer can then forge valid signatures for that signer without knowledge ...

Further Attacks and Improvement of a Certificateless Signature Scheme

2015 11th International Conference on Computational Intelligence and Security (CIS), 2015
Certificate less public key cryptography is an attractive paradigm since it eliminates the use of certificates in traditional public key cryptography and alleviates the inherent key escrow problem in identity-based cryptography. Recently, Xiong et al. Proposed a certificate less signature scheme and proved that their scheme is existentially unforgeable

A Revocable Certificateless Signature Scheme Without Pairing

2016
In a public key cryptosystem, an important problem is how to revoke a user. As we know, the certificateless public key cryptography (CLPKC) unites the qualities of the traditional public key system and the identity-based public key system. It is free of complicated certificate management and key escrow.
