Strongly Unforgeable Ring Signature Scheme from Lattices in the Standard Model
Journal of Applied Mathematics, 2014 In a ring signature scheme, a user selects an arbitrary ring to be able to sign a message on behalf of the ring without revealing the signer’s identity. Whistle-blowers especially find this useful.

Privacy Protection of VANET Based on Traceable Ring Signature on Ideal Lattice
IEEE Access, 2020 With the development of the Vehicular Ad-Hoc Network (VANET), protecting user privacy while ensuring security has become an immense challenge. A ring signature has the characteristics of no manager and unconditional anonymity, which can substantially ...

Adapting Lyubashevsky's Signature Schemes to the Ring Signature Setting [PDF]
, 2013 International audienceBasing signature schemes on strong lattice problems has been a long standing open issue. Today, two families of lattice-based signature schemes are known: the ones based on the hash-and-sign construction of Gentry et al.; and ...

Fail-Stop Ring Signature Scheme Based on Certificateless Cryptosystem [PDF]
Jisuanji gongcheng, 2020 Fail-stop group signature schemes can prevent opponents with strong compute power from counterfeiting signatures,and thereby implement privacy protection for users.On the basis of the fail-stop group signature scheme,this paper designs a fail-stop ring ...

ID-based ring signature on prime order group from asymmetric pairing
Tongxin xuebao, 2021 For the problem that the security proof was difficult to be realized under the standard model in the existing ID-based ring signature schemes, an ID-based ring signature scheme proven secure in the standard model was proposed.Firstly, the formal ...

Efficient Linkable Ring Signature Scheme [PDF]
Jisuanji gongchengA linkable ring signature, which is a special type of ring signature, can aid in verifying whether two signatures have been signed by the same user, without compromising anonymity. This feature enables it to play an important role in blockchains. However,

Cryptanalysis of Lattice-Based Blind Signature and Blind Ring Signature Schemes
IEEE Access, 2021 A blind signature enables a user to obtain signatures on any message from an authority who cannot acquire any information on the message being signed. A blind ring signature scheme is designed as a ring signature scheme with the blindness property.

A Ring-LWE-based digital signature inspired by Lindner–Peikert scheme
Journal of Mathematical Cryptology, 2022 In this article, we give a digital signature by using Lindner–Peikert cryptosystem. The security of this digital signature is based on the assumptions about hardness of Ring-LWE and Ring-SIS problems, along with providing public key and signature of ...
