Leakage-resilient certificateless public key encryption

Proceedings of the first ACM workshop on Asia public-key cryptography, 2013
In certificateless public key encryption (CL-PKE), the Private Key Generator (PKG) keeps a master secret key to generate a partial private key corresponding to a user's identity. Together with a secret value generated by the user, a full private key can be constructed for decryption.

Efficient Anonymous Multireceiver Certificateless Encryption

IEEE Systems Journal, 2017
To protect receiver privacy, researchers constructed anonymous multireceiver encryption by implanting anonymity in multireceiver encryption. It allows a sender to produce the identical ciphertext for multiple designated receivers. Every designated receiver can decrypt the ciphertext, but does not know who the other designated receivers are.

Efficient Certificateless Signature Schemes

2007
Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity based cryptography, the notion of certificateless public key cryptography was introduced. In this paper, to construct an efficient certificateless signature (CLS) scheme, we present a new approach compactly and ...

Security Mediated Certificateless Signatures

2007
In PKC 2006, Chow, Boyd and Gonzalez Neito introduced the notion of security mediated certificateless (SMC) cryptography. SMC cryptography equips certificateless cryptography with instantaneous revocation. They presented a formal security model with two constructions for SMC encryption. This paper studies SMC signatures.

Short-Key Certificateless Encryption

2011 Workshop on Lightweight Security & Privacy: Devices, Protocols, and Applications, 2011
The notion of certificate less public key encryption (CL-PKE or CLE) was initiated by Al Riyami and Paterson and grew out of the need for a public key mechanism to eliminate the built-in key escrow of identity based encryption (IBE) without introducing digital certificates and the management overhead that this entails.

Certificateless verifiably encrypted signature scheme

2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content, 2010
In this paper, we study the construction of verifiably encrypted signature in certificateless public key setting. We first present the notion and the new security model for certificateless verifiably encrypted signature (CLVES) and then present a concrete CLVES scheme based on Zhang's certificateless signature (CLS) [1], and provide the security ...

Certificateless signature and blind signature

Journal of Electronics (China), 2008
Certificateless 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 Threshold Signature Schemes

2005
We analyze the relationship and subtle difference between the notion of certificateless public key cryptography (CL-PKC) and identity-based schemes without a trusted private key generator (PKG), then propose a certificateless threshold signature scheme based on bilinear pairings.

Strongly secure certificateless short signatures

Journal of Systems and Software, 2012
Highlights? We introduce a new efficient and secure short certificateless signature scheme. ? It is strongly unforgeable. ? The security is based on the CDH assumption. ? The proposed scheme is provably secure against a relatively stronger adversary. Short certificateless signatures have come into limelight in recent years.
