A Lattice-Based Certificateless Traceable Ring Signature Scheme

, 2023
A ring signature (RS) scheme enables a group member to sign messages on behalf of its group without revealing the definite signer identify, but this also leads to the abuse of anonymity by malicious signers, which can be prevented by traceable ring ...
