A concrete certificateless signature scheme without pairings
, 2009 Certificateless public key cryptography was introduced to avoid the inherent key escrow problem in identity-based cryptography, and eliminate the use of certificates in traditional PKI. Most cryptographic schemes in certificateless cryptography are built

Certificateless Proxy Signature from RSA [PDF]
, 2020 Although some good results were achieved in speeding up the computation of pairing function in recent years, it is still interesting to design efficient cryptosystems with less bilinear pairing operation. A proxy signature scheme allows a proxy signer to

New certificateless short signature scheme
IET Information Security, 2013 The certificateless public key cryptography has attracted wide attention since it could solve the certificate management problem in the traditional public key cryptography and the key escrow problem in the identity‐based public key cryptography. Recently, several certificateless short signature schemes, which could satisfy the requirement of low ...

Security Analysis of a Certificateless Provable Data Possession Scheme in Cloud
IEEE Access, 2019 He et al. proposed a certificateless provable data possession protocol for big data storage on cloud. They claimed that the scheme is not only secure, but also can achieve data integrity checking without downloading the stored data from the cloud server.

Tight reduction for generic construction of certificateless signature and its instantiation from DDH assumption [PDF]
, 2019 Certificateless signature was proposed by Al-Riyami and Paterson to eliminate the certificate management in the public-key infrastructures and solve the key escrow problem in the identity-based signature. In 2007, Hu et al.
