Signcryption is a recently newer technology that is still in the process of being developed and made completely efficient. The purpose is to take the previous sign then encrypt method but by killing two birds with one stone. The technology is a scheme which can produce secret and authenticated messages sent between different parties.

Position-based proxy signcryption
2015 IEEE/CIC International Conference on Communications in China (ICCC), 2015Position-based cryptography has attracted lots of researchers' attentions. In mobile Internet, there are lots of position based security applications. For the first time, one new conception, position-based proxy signcryption is proposed. Based on a secure positioning protocol, one model of position-based proxy signcryption is proposed.

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.

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 ...

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 ...

Certificateless Signcryption in the Standard Model
Wireless Personal Communications, 2016Signcryption can realize encryption and signature simultaneously with lower computational costs and communicational overheads than those of the traditional sign-then-encrypt approach. Certificateless cryptosystem solves the key escrow problem in the identity-based cryptosystem and simplifies the public key management in the traditional public key ...

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.

Identity-Based Transitive Signcryption
2014Transitive signatures allow a signer to authenticate a graph in such a way that given two signatures on adjacent edges (i, j) and (j, k), anyone with public information can compose a signature on edge (i, k). In all existing transitive signature schemes, to prevent signature exposure, a secure channel is required between the signer and the recipient to

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 ...

A Constructive Perspective on Signcryption Security
2018Signcryption 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 ...
