Cryptanalysis of a Pairing-free Certificateless Signcryption scheme
ICT Express, 2021 Signcryption is a very useful cryptographic primitive that aims to achieve authentication and confidentiality in an efficient manner. We cryptanalyze the signcryption scheme of Wei and Ma (2019) which is claimed to be secure.

A Comprehensive Survey on Signcryption Security Mechanisms in Wireless Body Area Networks [PDF]
Sensors, 2022 WBANs (Wireless Body Area Networks) are frequently depicted as a paradigm shift in healthcare from traditional to modern E-Healthcare. The vitals of the patient signs by the sensors are highly sensitive, secret, and vulnerable to numerous adversarial ...

On security of a certificateless signcryption scheme
Information Sciences, 2013 It would be interesting if a signcryption scheme in the standard model could be made certificateless. One of the interesting attempts is due to Liu et al. [Z. Liu, Y. Hu, X. Zhang, H. Ma, Certificateless signcryption scheme in the standard model, Information Sciences 180 (3) (2010) 452-464].

Certificateless Aggregate Signcryption Scheme with Publicly Verifiable Pairless Operation [PDF]
Jisuanji kexue yu tansuo, 2022 Aggregate signcryption can combine ciphertext generated by different signcryption on different messages into a single ciphertext, which greatly reduces the total length of ciphertext and verification cost, and is more sui-table for low bandwidth and low ...

Certificateless hybrid signcryption [PDF]
Mathematical and Computer Modelling, 2009 Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional signature-then-encryption approach. In this paper, we address a question whether it is possible to construct a hybrid signcryption scheme in the ...

Certificateless signcryption [PDF]
Proceedings of the 2008 ACM symposium on Information, computer and communications security, 2008 Certificateless cryptography inherits a solution to the certificate management problem in public-key encryption from identity-based techniques, whilst removing the secret key escrow functionality inherent to the identity-based setting. Signcryption schemes achieve confidentiality and authentication simultaneously by combining public-key encryption and ...
