Certificate-Based Generalized Ring Signcryption Scheme

International Journal of Foundations of Computer Science, 2018
Generalized ring signcryption (GRSC) can realize ring signature and ring signcryption functions with only one key pair and one algorithm. It is very useful for a system with a large number of users, or whose function may be changed, or with limited storage space.

New ECDSA-Verifiable Multi-receiver Generalization Signcryption

2008 10th IEEE International Conference on High Performance Computing and Communications, 2008
Multi-receiver signcryption is a new cryptographic primitive that simultaneously fulfills both the functions of signature and multi-receiver encryption. Generalized Multi-Receiver signcryption can provide authenticity or confidentiality separately under specific inputs. Based on ECDSA, a generalized Multi-Receiver signcryption scheme is designed.

A generic construction of identity-based signcryption

2009 International Conference on Communications, Circuits and Systems, 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 propose the first generic construction of identity-based signcryption (GCIS) by using identity-

Attribute based generalized signcryption for online social network

2015 34th Chinese Control Conference (CCC), 2015
Online social network has brought varies and flexible secure demands. Attribute based generalized signcryption (ABGSC) could bring the combined or separate confidentiality and authentication adaptively, and eliminate the bottleneck of traditional public key encryption.

Generic Construction of Certificateless Signcryption Scheme

2016
Confidentiality and message authentication are the most important security goals that can be achieved simultaneously by Signcryption scheme. It is a cryptographic technique that performs both the functions of digital signature and public key encryption in a single logical step significantly at a lower cost than that of conventional method of signature ...

ECGSC: Elliptic Curve Based Generalized Signcryption

2006
Signcryption is a new cryptographic primitive that simultaneously fulfills both the functions of signature and encryption. The definition of Generalized Signcryption is proposed in the paper firstly. Generalized signcryption has a special feature that provides confidentiality or authenticity separately under the condition of specific inputs.

Generic Constructions for Signcryption with Non-interactive Non-repudiation

2015 International Conference on Computer Science and Mechanical Automation (CSMA), 2015
Non-interactive non-repudiation is a very important property of signcryption which enables a receiver to settle a repudiation dispute with the help of a judge without the need to engage in costly multi-round interactive communications with the judge. In this paper, we construct the generic "Sign-then-Encrypt" and "Encrypt-then-Sign" compositions for ...

Anti-quantum generalized signcryption scheme based on multivariate and coding

2019 Chinese Control And Decision Conference (CCDC), 2019
The development of quantum technology is changing with each passing day. While bringing convenience to us, the security problems it brings cannot be underestimated. By studying the multivariate cryptography and coding cryptography in anti-quantum cryptography, the core mapping of the improved version of Simple Matrix scheme is modified by LRPC code ...

Design of generalization of threshold signcryption scheme based on ECC

2010 IEEE International Conference on Information Theory and Information Security, 2010
To meet the needs of both encryption and certification for group communication, a generalization of threshold signcryption scheme based on elliptic curve cryptosystem is given. The scheme can simultaneously achieve (t,n) threshold signcryption and (k,l) threshold shared unsigncryption.
