Security-Mediated Certificateless Undeniable Signature Scheme

, 2018
Certificateless cryptosystems overcome the key escrow problem in identity-based cryptography. Mediated cryptography allows immediate revocation of public keys. Undeniable signatures limit the public verifiability of ordinary digital signatures.

Strongly secure certificateless one-pass authenticated key agreement scheme

Kuwait Journal of Science, 2015
As certificateless public key cryptography (CLPKC) could solve the problem of keyescrow, recently it has been studied more and more. Certificateless authenticated keyagreement (CLAKA), as an important part of the CLPKC, also attracts ...

A concrete certificateless signature scheme without pairings

, 2009
Certificateless public key cryptography was introduced to avoid the inherent key escrow problem in identity-based cryptography, and eliminate the use of certificates in traditional PKI. Most cryptographic schemes in certificateless cryptography are built

Extensions of Public-Key, Identity-Based and Certificateless Encryption Schemes

, 2008
In this work, we first study extensions and applications of the identity-based encryption (IBE) primitive, focusing on generic constructions. We first define what is meant by an identity-based key encapsulation mechanism before extending it to the multi ...

Comments on “A Conditional Privacy-Preserving Certificateless Aggregate Signature Scheme in the Standard Model for VANETs”

IEEE Access
In the above paper “A Conditional Privacy-Preserving Certificateless Aggregate Signature Scheme in the Standard Model for VANETs,” a pairing-based certificateless aggregate signature (CLAS) scheme was proposed.

A new provably secure certificateless short signature scheme

, 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.

Pairing-free certificateless blockchain-based access authentication method for spatial information network

Tongxin xuebao
Due to the single point failure and opaque certificate distribution process of the access authentication methods in a traditional terrestrial network, it was difficult to apply to a spatial information network with a highly complex and dynamic topology ...

Certificateless Signcryption without Pairing [PDF]

, 2010
Certificateless public key cryptography is receiving significant attention because it is a new paradigm that simplifies the traditional PKC and solves the inherent key escrow problem suffered by ID-PKC.

"Proposal for encryption and signature schemes under certificateless public key cryptography model"

, 2006
Sob o modelo de criptografia de chave pública baseada em identidades (ID-PKC), a própria identidade dos usuários é usada como chave pública, de modo a dispensar a necessidade de uma infra-estrutura de chaves públicas (ICP), na qual o gerenciamento de ...
