An Efficient Certificateless Generalized Signcryption Scheme

, 2018
Generalized signcryption can adaptively work as an encryption scheme, a signature scheme, or a signcryption scheme with only one algorithm. The paper proposes an efficient certificateless generic signcryption scheme without utilizing bilinear pairing ...

Two-way and anonymous heterogeneous signcryption scheme between PKI and IBC

Tongxin xuebao, 2017
Exiting heterogeneous signcryption schemes which were between public key infrastructure (PKI) and identity-based cryptosystem (IBC) have some limitations.A new heterogeneous signcryption scheme between PKI and IBC was proposed.In the random oracle mode ...

Revocable ID-based Signcryption Scheme

工程科学与技术, 2014
:In order to revoke private key leaks or malicious users in a signcryption system,a new revocable identity-based signcryption scheme was proposed.In this scheme,the master key was randomly divided into two parts,which were used to construct the initial ...

Provably Secure (Broadcast) Homomorphic Signcryption

, 2019
Signcryption has drawn a lot of attention due to its useful applications in many areas, in particular for applications where the computation and communication resources are constrained, for example, for lightweight devices.

Anonymous signcryption against linear Related-Key attacks

, 2013
A related-key attack (RKA) occurs when an adversary tampers the private key stored in a cryptographic hardware device and observes the result of the cryptographic primitive under this modified private key. In this paper, we concentrate on the security of

Ring signcryption scheme based on domestic cryptographic algorithm SM9

Tongxin xuebao
To address the linear computational increase with ring size in existing identity-based ring signcryption schemes, an efficient ring signcryption scheme based on the Chinese national cryptographic standard SM9 was proposed.

A Security Enhanced Generalized Threshold Signcryption Scheme with Deceit Detection

工程科学与技术, 2010
:By analyzing the first generalized threshold signcryption scheme (WCL scheme) and its improved schemes (TJC scheme, etc.), it was found that they can’t resist several attacks such as equation attack and can’t realize threshold designcryption.

ECGSC: Elliptic Curve based Generalized Signcryption Scheme [PDF]

, 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.
