Certificateless Generalized Signcryption
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.

Code-based generalized signcryption scheme with multi-receiver
Tongxin xuebao, 2020 In order to solve the problem of secure transmission of messages with multiple receivers,a code-based generalized signcryption scheme with multi-receiver was designed.Firstly,a multi-encrypted McEliece scheme that can meet the security of IND-CCA2 was ...

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.

Noncommutative Lightweight Signcryption for Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2013 Key management techniques for secure wireless-sensor-networks-based applications must minimally incorporate confidentiality, authenticity, integrity, scalability, and flexibility. Signcryption is the proper primitive to do this.

An Identity-Based Signcryption on Lattice without Trapdoor [PDF]
Journal of Universal Computer Science, 2019 Identity-based signcryption schemes based on large integer factorization and discrete logarithm problems were considered to be insecure for the quantum computer attack. Thus, choosing a quantum-resist platform and constructing secure schemes based on new

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 ...

Formalizing the Relationship Between Commitment and Basic Cryptographic Primitives [PDF]
Journal of Internet Services and Information Security, 2016 Signcryption is a cryptographic primitive which offers the functionality of both digital signature and encryption with lower combined computational cost. On the other hand, commitment scheme allows an entity to commit to a value, where the entity reveals
