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 ...

Forgery attacks on several certificateless signature schemes

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]

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

Revocable identity‐based matchmaking encryption in the standard model

IET 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 ...

Efficient ID-based certificateless signature scheme

Tongxin xuebao, 2008
Using gap diffie-hellman （GDH） groups, an efficient ID-based certificateless signature scheme was proposed, which could solve the key escrow problem through binding two partially public keys with a same identity.

Certificateless Public Auditing for Cloud‐Based Medical Data in Healthcare Industry 4.0

International Journal of Intelligent Systems, Volume 2023, Issue 1, 2023., 2023
In the context of healthcare 4.0, cloud‐based eHealth is a common paradigm, enabling stakeholders to access medical data and interact efficiently. However, it still faces some serious security issues that cannot be ignored. One of the major challenges is the assurance of the integrity of medical data remotely stored in the cloud. To solve this problem,

A concrete certificateless signature scheme without pairings [PDF]

, 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
