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

Cryptanalysis of a certificateless aggregate signature scheme [PDF]
IACR Cryptol. ePrint Arch., 2016 Recently, Nie et al. proposed a certificateless aggregate signature scheme. In the standard security model considered in certificateless cryptography, we are dealing with two types of adversaries. In this paper, we show that Nie et al.'s scheme is insecure against the adversary of the first type. In other words, although they claimed that their ...

An Efficient Certificateless Signature Scheme [PDF]
, 2006 Certificateless public key cryptography (CLPKC) is a paradi-gm 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 relatively few proposed schemes in the literature.

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 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.

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,
