A revocable certificateless signature scheme. [PDF]
IACR Cryptol. ePrint Arch., 2013 Certificateless public key cryptography (CLPKC), with properties of no key escrow and no certificate, has received a lot of attention since its invention. However, membership revocation in certificateless cryptosystem still remains a non-trivial problem:

An Efficient Certificateless Signature Scheme
2005Traditional certificate based cryptosystem requires high maintenance cost for certificate management. Although, identity based cryptosystem reduces the overhead of certificate management, it suffers from the drawback of key escrow. Certificateless cryptosystem combines the advantages of both certificate based and identity based cryptosystems as it ...

Certificateless Designated Verifier Signature Schemes
20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06), 2006Designated verifier signature schemes allow a signer to convince a designated verifier, in such a way that only the designated verifier will believe with the authenticity of such a signature. The previous constructions of designated verifier signature rely on the underlying Public Key Infrastructure, that requires both signer and verifier to verify the

Practical certificateless short signature scheme
International Journal of Electronic Security and Digital Forensics, 2014Certificateless cryptography is an attractive paradigm for public key cryptography since it does not require certificates in traditional public key cryptography and also solves the inherent key escrow problem in identity-based cryptography. Currently, certificateless short signature is receiving significant attention from the public key cryptography ...

The insecurity of a certificateless undeniable signature scheme
2016 International Wireless Communications and Mobile Computing Conference (IWCMC), 2016Duan proposed the first certificateless undeniable signature scheme in 2008. Later in 2012, Zhao and Ye proffered an efficient scheme which enjoys from a pairing-free sign algorithm. In this paper, we prove the insecurity of their efficient scheme by mounting two attacks on its invisibility and non-impersonation.

Certificateless Threshold Signature Schemes
2005We analyze the relationship and subtle difference between the notion of certificateless public key cryptography (CL-PKC) and identity-based schemes without a trusted private key generator (PKG), then propose a certificateless threshold signature scheme based on bilinear pairings.

Batch Verification for Certificateless Signature Schemes
2009 International Conference on Computational Intelligence and Security, 2009Batch verification is a practical and significant technique which is very useful for greatly reducing the computational cost of verifying many signatures simultaneously. This technique is very attractive for authentications in computation-limited applications such as sensor network and banking service.

An efficient revocable certificateless signature scheme
2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015In traditional PKC, public keys of the users are essentially random string generated from random secret keys, thus, public key certificates are required to link the relations between user's identities and their public keys. In ID-based cryptography, public keys are identities such as names, email address, and so on.

Certificateless Proxy Signature Scheme in the Standard Model
Fundamenta Informaticae, 2018Proxy signature is extension of the standard signature, in which the original signer can delegate his or her signing capability to proxy signer in such a way that the latter can sign messages on behalf of the former. Certificateless cryptography eliminates the need of certificates in the traditional public key cryptography and solves the inherent key ...

Certificateless Homomorphic Signature Scheme for Network Coding
IEEE/ACM Transactions on Networking, 2020Homomorphic signature is an extremely important public key authentication technique for network coding to defend against pollution attacks. As a public key cryptographic primitive, it also encounters the same problem of how to confirm the relationship between some public key $pk$ and the identity $ID$ of its owner.
