An Efficient Certificateless Signature Scheme [PDF]
, 2006 Certificateless public key cryptography (CLPKC) is a paradi-gm to solve the inherent key escrow problem suffered by identity-based cryptography (IBC). While certificateless signature is one of the most important security primitives in CLPKC, there are relatively few proposed schemes in the literature.

Cryptanalysis of a certificateless aggregate signature scheme [PDF]
IACR Cryptol. ePrint Arch., 2016 Recently, Nie et al. proposed a certificateless aggregate signature scheme. In the standard security model considered in certificateless cryptography, we are dealing with two types of adversaries. In this paper, we show that Nie et al.'s scheme is insecure against the adversary of the first type. In other words, although they claimed that their ...

Certificateless signature scheme without random oracles [PDF]
Tongxin xuebao, 2015 The security of certificateless signature schemes can be proved under the random oracle model.However，any implementation of the random oracle may result in insecure schemes.Some certificateless signature schemes without random oracles are not secure ...
