Journal of Information Systems and Operations Management, 2011 The aim of this paper is to provide an overview for the research that has been done so far in signcryption area. The paper also presents the extensions for the signcryption scheme and discusses the security in signcryption. The main contribution to this paper represents the implementation of the signcryption algorithm with the examples provided.

Indentity-based broadcast signcryption
Computer Standards and Interfaces, 2008Broadcast encryption schemes allow a center to deliver encrypted data to a large set of users so that only a particular subset of privileged users can decrypt it. Most of previous works about broadcast encryption only provide confidentiality of the message.

A Constructive Perspective on Signcryption Security [PDF]
, 2018 Signcryption is a public-key cryptographic primitive, originally introduced by Zheng (Crypto ’97), that allows parties to establish secure communication without the need of prior key agreement. Instead, a party registers its public key at a certificate authority (CA), and only needs to retrieve the public key of the intended partner from the CA before ...

Provable secure identity based generalized signcryption scheme
Theoretical Computer Science, 2010 According to actual needs, a generalized signcryption scheme can flexibly work as an encryption scheme, a signature scheme or a signcryption scheme. In this paper, firstly, we give a security model for identity based generalized signcryption which is ...

Concurrency and Computation: Practice and Experience, 2012
SUMMARYSigncryption is a cryptographic primitive that performs simultaneously both the functions of digital signature and public‐key encryption, at a cost significantly lower than that required by the traditional signature‐ then‐encryption approach.

Efficient Constructions of Signcryption Schemes and Signcryption Composability
2009In this paper, we investigate simple but efficient constructions of signcryption schemes. Firstly, we show how symmetric primitives can be used to efficiently achieve outsider multi-user security, leading to a signcryption scheme with the currently lowest ciphertext and computational overhead.

Efficient Distributed Signcryption Scheme as Group Signcryption
2003The existing distributed signcryption is designed for distributing a signcrypted message to a designated group. However, it does not provide confidentiality of sender ID and its extension to a group signcryption has certain weakness. This study solves the weakness and extends to an efficient group signcryption.

Efficient Signcryption for Heterogeneous Systems
IEEE Systems Journal, 2013Privacy and authentication are the two main security goals in secure communications. To solve the secure communications problem between two heterogeneous systems, we propose two efficient signcryption schemes that can simultaneously achieve confidentiality, integrity, authentication, and nonrepudiation in a logical single step.

Universally Composable Signcryption
2007One of the challenges within public-key based cryptosystems is providing the user with a convenient interface, while retaining security. In the universal composability framework, we propose an ideal functionality for secure messaging, with a user-friendly interface.
