A Novel Framework in Cloud Security: Remote Signcryption

IEEE Internet of Things Journal
Ensuring data integrity and confidentiality is critical in communication systems. Traditional methods, such as separate encryption and signature schemes, often lead to inefficiencies. While signcryption methods address both needs simultaneously, they are

Universal Designated Verifier Signcryption

2012
Universal 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.

CASKA-CRT: Chinese Remainder Theorem Empowered Certificateless Aggregate Signcryption Scheme With Key Agreement in IoVs

IEEE Transactions on Intelligent Vehicles
To enhance the privacy of messages in Internet of Vehicles (IoVs), it is critical to preserve the communication security between Road Side Unit (RSU) and numerous vehicles.

Provably Secure Homomorphic Signcryption

2017
Signcryption has shown many useful applications, in particular for the environment where the computation and communication resources are constrained, for instance, for applications on lightweight devices. However, we notice that traditional signcryption schemes do not support homomorphic properties, which are very useful in many application scenarios ...

Maintaining Chain of Custody using Attribute Based Signcryption (ABSC)

International Conference on Evolutionary Computation
In the evolving digital world, the exchange of information or raw data has been so easy, but their security has been diminished due advancement in technology.

Identity-Based Transitive Signcryption

2014
Transitive 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

Distributed Signcryption from Pairings

2011
The 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.

Privacy Preserving Signcryption Scheme

2016
Signcryption is a public-key cryptographic primitive that is a synthesis of encryption and digital signature schemes. We present a signcryption scheme using anonymous attribute based encryption. The scheme uses the notion of identity-based digital signature on the message encrypted under the attribute based encryption scheme.

A Secure and Lightweight NDN-Based Vehicular Network Using Edge Computing and Certificateless Signcryption

IEEE Internet of Things Journal
Named data networking (NDN), which is an implementation of information-centric networking (ICN), has emerged as a promising new direction in networking as a result of the shortcomings of the transmission control protocol/Internet protocol (TCP/IP ...

Threshold Attribute-Based Signcryption

2010
In 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 ...
