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 ...

Certificateless Threshold Signature Schemes

2005
We 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.

A certificateless signature scheme and a certificateless public auditing scheme with authority trust level 3+

Journal of Ambient Intelligence and Humanized Computing, 2017
Many certificateless cryptosystems have been proposed for cloud security applications. These applications have to face the inherent issues of dealing with low authority trust levels, especially when the cloud server takes charge of doing the role of the key generation center (KGC), that is the authority to trust. This paper focuses on popular authority
