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.

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

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 ...

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,

Certificateless Network Coding Ring Signature Scheme [PDF]

Security and Communication Networks, 2021
Traditional certificateless ring signature is not suitable for the network coding environment. In this view, a new certificateless network coding ring signature (CL-NCRS) is devised by using the techniques of multisource network coding and certificateless ring signature.
