Hierarchical Attribute-Based Signatures
, 2018 Attribute-based Signatures (ABS) are a powerful tool allowing users with attributes issued by authorities to sign messages while also proving that their attributes satisfy some policy. ABS schemes provide a flexible and privacy-preserving approach to authentication since the signer’s identity and attributes remain hidden within the anonymity set of ...
