A Strong RSA-based and Certificateless-based Signature Scheme
, 2016 [[abstract]]The certificateless-based signature system allows people to verify the signature without the certificate. For this reason, we do not need the certificate authority (CA) to store and manage users’ certificates and public keys.

Efficient and provably-secure certificateless signature scheme without bilinear pairings [PDF]
, 2011 Many certificateless signature schemes using bilinear pairings have been proposed. But the relative computation cost of the pairing is approximately twenty times higher than that of the scalar multiplication over elliptic curve group. In order to improve

A Revocable Certificateless Sanitizable Signature Scheme With Batch Verification
IEEE AccessIn medical and healthcare application scenarios, data integrity and user privacy are often concerned the most. A sanitizable signature scheme is a common adopted approach since it admits an authorized person to sanitize partial sensitive information of ...

An RSA-based Certificateless Multi-signature Scheme
工程科学与技术, 2016 :In order to improve the efficiency of existing multi-signature schemes based on bilinear pairings and relieve the inherent key escrow problems in the identity-based multi-signature scheme,an RSA-based certificateless multi-signature scheme was proposed ...

Generic construction of certificateless signature
, 2019 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.

Deep Attacks of a Certificateless Signature Scheme [PDF]
, 2013 Certificateless 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.

On the security of a certificateless aggregate signature scheme [PDF]
, 2013 Aggregate signature can combinensignatures on nmessages fromnusers into a single short signature, and the resulting signature can convince the verifier that thenusers indeed signed the ncorresponding messages.
