Key replacement attack against a generic construction of certificateless signature
TL;DR: This paper shows that the generic construction of digital signature schemes under the framework of certificateless cryptography is insecure against key replacement attack, and proposes a modification of their scheme and shows its security in a new and simplified security model.

An efficient certificateless undeniable signature scheme
TL;DR: This paper proposes a new certificateless undeniable signature scheme which is much more efficient comparing to Duan's scheme, and proves the security of the scheme in the strong security model based on the intractability of some well-known pairing-based assumptions in the random oracle model.

A digital signature scheme secure against adaptive chosen-message attacks
TL;DR: A digital signature scheme based on the computational difficulty of integer factorization possesses the novel property of being robust against an adaptive chosen-message attack: an adversary who receives signatures for messages of his choice cannot later forge the signature of even a single additional message.

Certificateless Public Key Cryptography
TL;DR: In this article, the concept of certificateless public key cryptography (CL-PKC) was introduced and made concrete, which does not require certificates to guarantee the authenticity of public keys.
