Anti-Quantum Lattice-Based Ring Signature Scheme and Applications in VANETs [PDF]
Entropy, 2021 Message authentication is crucial because it encourages participants to accept countermeasures and further transmit messages to legitimate users in a network while maintaining the legitimacy of the identity of network members. An unauthorized user cannot

Identity-Based Linkable Ring Signature Scheme
IEEE Access, 2019 A ring signature is an anonymous signature that implements both the authentication of the message and the anonymity of the signer. In a “normal” ring signature scheme, the same signer can generate multiple ring signatures, but the verifier ...

Ring Signature With Unconditional Anonymity in the Plain Model [PDF]
IEEE Access, 2021 Ring signature allows a user to sign messages as a member of a set of users, which is called the ring. In addition to an unforgeability, ring signature ensures that nobody can detect which member in the ring signs the message.

Strongly Unforgeable Ring Signature Scheme from Lattices in the Standard Model [PDF]
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.
