Forgery attacks on several certificateless signature schemes

open access: yes网络与信息安全学报, 2020
Since Al-Riyami and Paterson proposed the novel concept of certificateless cryptography and the first certificateless signature scheme in 2003, a lot of certificateless signature schemes were proposed one after another. Recently, Tang et al proposed nine

A Revocable Certificateless Signature Scheme [PDF]

open access: yesJournal of Computers, 2014
Certificateless public key cryptography (CLPKC), with properties of no key escrow and no certificate, has received a lot of attention since its invention. However, how to revoke a user in certificateless cryptosystem still remains a problem: the existing solutions are not practical for use due to either a costly mediator or enormous computation (secret

Certificateless Designated Verifier Proxy Signature [PDF]

open access: yes, 2021
Proxy signature (PS) is a kind of digital signature, in which an entity called original signer can delegate his signing rights to another entity called proxy signer.

A Certificateless Ring Signature Scheme with High Efficiency in the Random Oracle Model [PDF]

open access: yes, 2017
Ring signature is a kind of digital signature which can protect the identity of the signer. Certificateless public key cryptography not only overcomes key escrow problem but also does not lose some advantages of identity-based cryptography ...

A provably security and efficient certificateless short signature scheme [PDF]

open access: yesJisuanji gongcheng, 2019
In the certificateless cryptography system,there is no authentication relationship between the public key and the holder,which may cause a problem that a malicious user replaces the user’s public key.To This end,this paper improves the definition of ...

Revocable identity‐based matchmaking encryption in the standard model

open access: yesIET Information Security, Volume 17, Issue 4, Page 567-581, July 2023., 2023
RIB‐ME provides the features of data confidentiality, sender authenticity and efficient revocation, where the security can be reduced to static assumptions in the standard model. Abstract Identity‐based Matchmaking Encryption (IB‐ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access ...

Insecurity of a certificateless aggregate signature scheme [PDF]

open access: yesSecurity and Communication Networks, 2016
AbstractAs an important kind of digital signature, the aggregate signature could aggregate n signatures into a signature and verify those signatures simultaneously. It is suitable for the constrained environment with limited ability of computation and communication. Recently, Chen et al.

Performance analysis of certificateless signature for IKE authentication

open access: yes, 2011
Elliptic curve-based certificateless signature is slowly gaining attention due to its ability to retain the efficiency of identity-based signature to eliminate the need of certificate management while it does not suffer from inherent private key escrow ...

Certificateless Signature Scheme Based on Rabin Algorithm and Discrete Logarithm [PDF]

open access: yes, 2016
Certificateless signature can effectively immue the key escrow problem in the identity-based signature scheme. But the security of the most certificateless signatures usually depends on only one mathematical hard problem, which makes the signature ...

Blockchain‐Based Secure Data Sharing for IoT Devices Using Smart Contracts: A Systematic Review and Taxonomy

open access: yesIET Blockchain, Volume 6, Issue 1, January/December 2026.
ABSTRACT The proliferation of Internet of Things (IoT) devices has created an urgent demand for secure, scalable and interoperable data‐sharing architectures. Centralized paradigms exhibit single points of failure, inadequate access control and limited transparency, rendering them structurally misaligned with the distributed nature of IoT deployments ...
