T3AT: Threshold-Authorized, Threshold-Redeemable, and Non-Transferable Anonymous Tokens
- Published
- Record updated
Summary
The authors construct a threshold BBS+ signing protocol using verifiable multiplication-to-addition (MtA) techniques derived from vector oblivious linear evaluation (VOLE), with security proven in the Universal Composability (UC) framework. Building on this, they introduce T3AT, threshold-authorized and threshold-redeemable, non-transferable anonymous tokens that support collaborative issuance and verification under malicious adversaries and dishonest majorities, without trusted hardware or centralized authorities. The source reports that performance evaluation demonstrates practicality, efficiency and scalability.
