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 ...

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 ...

A Publicly Verifiable Leveled Fully Homomorphic Signcryption Scheme
IET Information Security, 2023 With the deepening of research, how to construct a fully homomorphic signcryption scheme based on standard assumptions is a problem that we need to solve. For this question, recently, Jin et al.

Certificateless Generalized Signcryption [PDF]
Physics Procedia, 2012 AbstractGeneralized Signcryption is a fresh cryptographic primitive that not only can obtain encryption and signature in a single operation, but also provide encryption or signature model alone when needed. This paper proposed a formal definition of certificateless generalized signcryption(CLGSC), then provide the security model of CLGSC.

Provable Secure Generalized Signcryption [PDF]
Journal of Computers, 2010 Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an en- cryption scheme, a signature scheme or a signcryption scheme[5]. However,the security proof in their paper is uncorrect. our contribution are as following:First we give security notions for this new primitive.Secnond,we give an attack to [4] which ...

, 2010 The primary motivation for signcryption was the gain in efficiency when both encryption and signing need to be performed. These two cryptographic operations may be done sequentially either by first encrypt and then sign (EtS) or alternatively, by first sign and then encrypt (StE).

A secure anonymous proxy signcryption scheme
Journal of Mathematical Cryptology, 2017 We introduce a new cryptographic primitive identity-based anonymous proxy signcryption which provides anonymity to the proxy sender while also providing a mechanism to the original sender to expose the identity of the proxy sender in case of misuse.
