Cryptanalysis of an Efficient Signcryption Scheme with Forward Secrecy Based on Elliptic Curve
, 2008 The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Several signcryption schemes are proposed throughout the years, each of them having

ID-based Ring Signature and Proxy Ring Signature Schemes from Bilinear Pairings [PDF]
, 2004 In 2001, Rivest et al. firstly introduced the concept of ring signatures. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. The first scheme proposed by Rivest et al.

Lattice-based ring signcryption for consortium blockchain
Journal of King Saud University: Computer and Information Sciences, 2023 Ring signcryption with no group administrator satisfies the decentralization and blockchain anonymity. In this article, we construct new lattice-based ring signcryption scheme suitable for consortium blockchain (CB-LRSCS), in which the smart contract ...

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 ...

Signcryption schemes with insider security in an ideal permutation model
Journal of Mathematical Cryptology, 2019 Signcryption aims to provide both confidentiality and authentication of messages more efficiently than performing encryption and signing independently. The “Commit-then-Sign & Encrypt” (CtS&E) method allows to perform encryption and signing in parallel ...

Identity Based Generalized Signcryption Scheme in the Standard Model
Entropy, 2017 Generalized signcryption (GSC) can adaptively work as an encryption scheme, a signature scheme or a signcryption scheme with only one algorithm. It is more suitable for the storage constrained setting.
