Efficient signcryption in the standard model
Concurrency and Computation: Practice and Experience, 2011SUMMARYSigncryption 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. The performance advantage of signcryption over the signature‐then‐encryption method makes signcryption ...

Signcryption with Quantum Random Oracles
2018Signcryption is a cryptographic scheme that achieves the functionalities of both public-key encryption and digital signatures. It is an important scheme for realizing a mechanism of sending and/or receiving messages in a secure way, since it is understood that signcryption is a public-key based protocol to realize a secure channel from an insecure ...

An improved certificateless signcryption scheme
2016 13th International Iranian Society of Cryptology Conference on Information Security and Cryptology (ISCISC), 2016A certtificateless signcryption (CLSC) scheme is an important primitive in cryptographic protocols which provides the goals of signing and encryption, simultaneously. In 2010, Liu et al presented the first certificateless signcryption scheme in the standard model, but their scheme is vulnerable against different attacks presented in the literature ...

Threshold Attribute-Based Signcryption
2010In this paper, we propose a new threshold attribute-based signcryption scheme secure in the standard model. The scheme provides message confidentiality, and authenticity of a message in addition to attesting the attributes of the sender. Such a property is useful in applications such as electronic card, digital prescription carrier devices, secure and ...

Distributed Signcryption from Pairings
2011The distributed signcryption scheme was proposed by Mu and Varadharajan in their paper presented at INDOCRYPT 2000. Since then some more schemes have been proposed for distributed signcryption and extended for group signcryption. In 2007, Li et al [15] proposed signcryption scheme with key privacy.

Universal Designated Verifier Signcryption
2012Universal Designated Verifier Signature (UDVS) was introduced by Steinfeld et al. in Asiacrypt'03. UDVS allows a signature holder, who has a signature of a signer, to convince a designated verifier that he is in possession of a signer's signature, while the verifier cannot transfer such conviction to anyone else.

Efficient and Proactive Threshold Signcryption
2005To make the system more secure and robust, threshold schemes are proposed to avoid single point failure. At the same time, there are more and more applications which utilize the two basic blocks encryption and digital signature to secure message delivery (such as SSL, SSH).

Improvements and generalisations of signcryption schemes.
2014In this work, we study the cryptographic primitive: signcryption, which combines the functionalities of digital signatures and public-key encryption. We first propose two generic transforms from meta-ElGamal signature schemes to signcryption schemes.
