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.

CLUE: Certificateless Updatable Encryption.

2023
We formalise certificateless public-key updatable encryption (CLUE), a primitive that has yet to be defined in the public-key updatable encryption (PKUE) literature. Traditionally, PKUE allows outsourcing ciphertext key rotation to an untrusted host using a special token such that the ciphertext is updated to a distinct period known as an epoch. Key to

Security Mediated Certificateless Signatures

2007
In PKC 2006, Chow, Boyd and Gonzalez Neito introduced the notion of security mediated certificateless (SMC) cryptography. SMC cryptography equips certificateless cryptography with instantaneous revocation. They presented a formal security model with two constructions for SMC encryption. This paper studies SMC signatures.

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
