On the Security of Certificateless Signature Schemes
International Journal of Distributed Sensor Networks, 2013 Wireless Sensor Network (WSN) has proved its presence in various real time applications and hence the security of such embedded devices is a vital issue. Certificateless cryptography is one of the recent paradigms to provide security.

New certificateless short signature scheme
IET Information Security, 2013 The certificateless public key cryptography has attracted wide attention since it could solve the certificate management problem in the traditional public key cryptography and the key escrow problem in the identity‐based public key cryptography. Recently, several certificateless short signature schemes, which could satisfy the requirement of low ...

Certificateless Linkable Ring Signature Scheme
IEEE Access, 2020 Ring signature is an anonymous signature that both authenticates the message and protects the identity information of the signer. It is suitable for scenarios such as anonymous network access, online auctions, etc.

Insecurity of a Certificateless Aggregate Signature Scheme [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 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.

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

A Revocable Certificateless Signature Scheme [PDF]
Journal 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
