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 ...

A new provably secure certificateless short signature scheme [PDF]
Computers and Mathematics With Applications, 2011 Certificateless public key cryptography simplifies the complex certificate management in the traditional public key cryptography and resolves the key escrow problem in identity-based cryptography. In 2007, Huang et al.

Hierarchical Certificateless Signatures
2010 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing, 2010Certificateless cryptography eliminates the key escrow problem in identity-based cryptography. Hierarchical cryptography exploits a practical security model to mirror the organizational hierarchy in the real world. In this paper, to incorporate the advantages of both types of cryptosystems, we instantiate hierarchical certificate less cryptography by ...

On constructing certificateless proxy signature from certificateless signature
Journal of Shanghai Jiaotong University (Science), 2008In proxy signature schemes, an original signer A delegates its signing capability to a proxy signer B, in such a way that B can sign message on behalf of A. The recipient of the final message verifies at the same time that B computes the signature and that A has delegated its signing capability to B.

Certificateless group inside signature
Proceedings Autonomous Decentralized Systems, 2005. ISADS 2005., 2005In distributed networks, the signer wants his signature to be verified by anyone in the same group with him and the recipient wants to verify the signature independently. Motivated by this consideration, a certificateless group inside signature is presented in this paper.

Certificateless signature and blind signature
Journal of Electronics (China), 2008Certificateless public key cryptography is a new paradigm introduced by Al-Riyami and Paterson. It eliminates the need of the certificates in traditional public key cryptosystems and the key escrow problem in IDentity-based Public Key Cryptography (ID-PKC).

Certificateless Partially Blind Signature
2012 26th International Conference on Advanced Information Networking and Applications Workshops, 2012Blind signatures play a central role in applications such as e-cash and e-voting systems, while partially blind signature is an even more applicable variant. This paper proposes a Certificate less Partially Blind Signature (CPBS) by laying its construction on bilinear pairings over Gap Diffie-Hellman (GDH) Group for solving the key escrow problem in ...
