An efficient certificateless signature scheme

open access: yes, 2006
Certificateless public key cryptography (CLPKC) is a paradigm to solve the inherent key escrow problem suffered by identity-based cryptography (IBC). While certificateless signature is one of the most important security primitives in CLPKC, there are ...

Comments on “Certificateless Short Aggregate Signature Scheme for Mobile Devices”

open access: yesIEEE Access
In the above paper “Certificateless Short Aggregate Signature Scheme for Mobile Devices” a pairing-based certificateless aggregate signature (CLAS) scheme was proposed. Although the authors claim that their CLAS scheme is secure and provide

a provable authenticated certificateless group key agreement with constant rounds

open access: yes, 2012
Group key agreement protocols allow a group of users, communicating over a public network, to establish a shared secret key to achieve a cryptographic goal.

An efficient certificateless aggregate signature with constant pairing computations

open access: yes, 2013
An aggregate signature scheme enables an algorithm to aggregate n signatures of n distinct messages from n users into a single short signature. This primitive is useful in resource-constrained environment since they allow bandwidth and computational ...

cryptanalysis of some certificateless signature schemes in the standard model

open access: yes, 2013
Certificateless Public Key Cryptography, which removes the necessity of certificate to ensure the authentication of the user's public key in the traditional Certificate-Based Public Key Cryptography and also overcomes the inherent key escrow problem in ...

Cryptanalysis and improvement of an efficient certificateless signature scheme

open access: yes, 2008
In traditional digital signature schemes, certificates signed by a trusted party are required to ensure the authenticity of the public key. In Asiacrypt 2003, the concept of certificateless signature scheme was introduced.

key replacement attack against a generic construction of certificateless signature

open access: yes, 2006
Certificateless cryptography involves a Key Generation Center (KGC) which issues a partial key to a user and the user also independently generates an additional public/secret key pair in such a way that the KGC who knows only the partial key

A PROVABLY SECURE CERTIFICATELESS PROXY SIGNATURE SCHEME

open access: yes, 2014
Proxy signature, a variant of digital signature, is in the limelight in recent years for secure communication. For instance, when a manager is occupied with business matters, or travelling on business, he has to delegate an agent to deal with his day ...
