Certificateless Signcryption in the Standard Model

Wireless Personal Communications, 2016
Signcryption can realize encryption and signature simultaneously with lower computational costs and communicational overheads than those of the traditional sign-then-encrypt approach. Certificateless cryptosystem solves the key escrow problem in the identity-based cryptosystem and simplifies the public key management in the traditional public key ...

Certificateless Partially Blind Signature

2012 26th International Conference on Advanced Information Networking and Applications Workshops, 2012
Blind 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 ...

Certificateless Signature Revisited

2007
In this paper we revisit the security models of certificateless signatures and propose two new constructions which are provably secure in the random oracle model. We divide the potential adversaries according to their attack power, and for the first time, three new kinds of adversaries are introduced into certificateless signatures.

Certificateless group inside signature

Proceedings Autonomous Decentralized Systems, 2005. ISADS 2005., 2005
In 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.

An improved certificateless signcryption scheme

2016 13th International Iranian Society of Cryptology Conference on Information Security and Cryptology (ISCISC), 2016
A certtificateless signcryption (CLSC) scheme is an important primitive in cryptographic protocols which provides the goals of signing and encryption, simultaneously. In 2010, Liu et al presented the first certificateless signcryption scheme in the standard model, but their scheme is vulnerable against different attacks presented in the literature ...

Certificateless Aggregate Signature Scheme

2010 International Conference on E-Business and E-Government, 2010
This paper puts forward a secure construction of certificateless aggregate signature scheme using bilinear maps. The security of our scheme is based on the infeasibility of the Computational Diffie-Hellman problem and is formally proven in the strongest security model of certificateless aggregate signature schemes.

A certificateless approach to onion routing

International Journal of Information Security, 2016
Onion routing protocols allow users to establish anonymous channels to preserve their privacy over a public network. Several protocols implementing this primitive have been proposed in recent years, and The onion routing network (Tor), a real-life implementation, provides an onion routing service to thousands of users over the Internet.

CLUE: Certificateless Updatable Encryption. [PDF]

, 2023
We formalise certificateless public-key updatable encryption (CLUE), a primitive that has yet to be defined in the public-key updatable encryption (PKUE) literature. Traditionally, PKUE allows outsourcing ciphertext key rotation to an untrusted host using a special token such that the ciphertext is updated to a distinct period known as an epoch. Key to

Certificateless multi-proxy signature

Computer Communications, 2011
Multi-proxy signature is a scheme that an original signer authorizes a proxy group as his proxy agent and later only the cooperation of all proxy signers in the proxy group could sign messages on behalf of the original signer. To our best knowledge, most of the existing multi-proxy signature schemes are proposed in public key infrastructure or identity-
