An Identity-Based Ring Signcryption Scheme
2012Signcryption enables a user to perform digital signature for providing authenticity and public key encryption for providing message confidentiality simultaneously in a single logical step with a cost lesser than sign-then- encrypt approach. As the concept of ring signcryption emerged, various practical applications like electronic transaction protocol ...

Cryptanalysis of Two Ring Signcryption Schemes
2009Ring signcryption scheme is an important cryptographic primitive that can be used to protect privacy and authenticity of a collection of users who are connected through an ad-hoc network, such as Bluetooth.In this paper,we analyze two ring signcryption schemes:Wang-Zhang-Ma's scheme (2007) and Zhu-Zhang-Wang's scheme (2008).

An Efficient Signcryption Scheme Using Near-Ring Hybrid Approach for an IoT-Based System
Int. J. e Collab., 2022Signcryption is a cryptographic primitive which combines both the functions of digital signature and public key encryption logically in a single step, with a computational cost significantly less than the traditional signature-then-encryption approach ...

Constructing Designated-Verifier Ring Signature and Ring Signcryption under the k-CCA2 Assumption
2012 Fourth International Conference on Intelligent Networking and Collaborative Systems, 2012Ring signatures are one of the signatures that can enhance the anonymity of the users who want to sign documents not only in the way of authentication but also privacy. In this paper, we propose a simple but secure designated verifier ring signature scheme from bilinear pairing.

An ID-based ring signcryption scheme for wireless sensor networks
IET International Conference on Wireless Sensor Network 2010 (IET-WSN 2010), 2010Ring signcryption enables a user to send a message confidentially and authentically to a specific receiver in an anonymous way. In this paper a new identity-based ring signcryption scheme (IBRSC) from pairings was presented, which was proven to be satisfied with IND-CCA2 and EUF-CMA security formally.

New Multi-Receiver Id-Based Ring Signcryption Scheme
2013The first multi-receiver id-based ring signcryption (mIBRSC) scheme was proposed by Lal et al., which enables the user to anonymously deliver some important information to multiple receivers in a secure and authenticated manner. In this chapter, we show that their scheme is insecure against adaptive chosen ciphertext attacks. Furthermore, we present an

Self-Certified Ring Signcryption Scheme Based on Discrete Logarithm Problem
Advanced Materials Research, 2014This paper analyzes and summarizes existing ring signcryption schemes, combined with self-certified cryptosystem and ring signcrypption, we proposed a self-certified ring signcryption based on Discrete Logarithm Problem. The scheme proposed not only guaranties ring signcrption’s anonymity, confidentiality, unforgeability and other security features ...
