Anonymous Tokens with Private Metadata Bit
Ben Kreuter and Tancrede Lepoint and Michele Orru and Mariana Raykova
Abstract
We present a cryptographic construction for anonymous tokens with private metadata bit, a primitive that enables an issuer to provide a user with anonymous trust tokens that can embed a single private metadata bit, which is accessible only to the party who holds the secret authority key and is private with respect to anyone else. Our construction provides unforgeability, unlinkability and privacy for the metadata bit properties.
