Lwe - PowerPoint PPT Presentation

Research presented at CRYPTO 2021 introduces a compact ring signature scheme using components instantiated from LWE. The scheme allows each signer to sign on behalf of a ring of users, offering properties of unforgeability, anonymity, and compactness. The work explores the possibility of building co
