Identity-based threshold ring signcryption from pairing
International Journal of Electronic Security and Digital Forensics, 2014This paper presents an identity-based threshold ring signcryption scheme. With this technique, any group of t entities can choose n - t entities to generate a t-out-of-n signcryption on behalf of the group of n members, yet the actual signcrypters remain anonymous. The scheme is proven to be indistinguishable against adaptive chosen ciphertext attacks,

A new identity-based ring signcryption scheme
International Journal of Electronic Security and Digital Forensics, 2014This paper presents a new identity-based ring signcryption scheme. With this technique, anyone can choose n − 1 entities to generate a verifiable ring signcryption on behalf of the group of n members, yet the actual signcrypter remain anonymous. The scheme is proven to be indistinguishable against adaptive chosen ciphertext attacks, existentially ...

Ring signature scheme for ECC-based anonymous signcryption
Computer Standards & Interfaces, 2009This study presents an elliptic curve cryptosystem-based signcryption scheme with anonymity features. The scheme possesses the properties of elliptic curve cryptosystem and ring signature. While the technique of ring signature endows the signers with anonymity, the elliptic curve cryptosystem provides advantages like high security, low computation load,

IDTRSC: ID-Based Traceable Ring Signcryption Framework for Data Sharing Without Key Escrow
IEEE Transactions on Vehicular TechnologyThe capability to share data across different entities is increasingly pronounced in our data-driven and centric society. However, we also have to ensure properties such as data confidentiality, unforgeability, anonymity and traceability are supported in

An Improved Identity-Based Ring Signcryption Scheme
Information Security Journal: A Global Perspective, 2013In this paper, we show that the identity-based ring signcryption scheme suggested by Zhu, Zhang, and Wang 2009 does not reach the security as they claimed it does. To make up for this defect, we propose a rescue scheme and prove the revised scheme is secure under the random oracle model.

On the Security of Identity Based Ring Signcryption Schemes [PDF]
, 2009 Signcryption is a cryptographic primitive which offers authentication and confidentiality simultaneously with a cost lower than signing and encrypting the message independently. Ring signcryption enables a user to signcrypt a message along with the identities of a set of potential senders (that includes him) without revealing which user in the set has ...

An efficient and provable secure identity-based ring signcryption scheme
Computer Standards & Interfaces, 2009ID-based ring signcryption schemes (IDRSC) are usually derived from bilinear parings, a powerful but computationally expensive primitive. The number of paring computations of all existing ID-based ring signcryption schemes from bilinear pairings grows linearly with group size, which makes the efficiency of ID-based schemes over traditional schemes ...

Insecurity of a Pairing-Free Certificateless Ring Signcryption Scheme
Wireless Personal Communications, 2017Recently, Sharma et al. (Wirel Pers Commun, 2015. doi: 10.1007/s11277-015-2698-2 ) proposed a pairing-free certificateless ring signcryption scheme (PF-CLRSC) and used it for the environment of wireless sensor networks. They claimed that their scheme was provably secure.
