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 ...

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.

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 ...
