      Attribute-based credentials (ABC) is an authentication scheme to identify an entity without revealing its identity. Privacy-friendly ABC mechanism does not ask for the revelation of users’ whole attributes. Instead, it only requests a predicate over the attributes, which is different from traditional PKI and ABC. No full identification is required in privacy-ABC by following the zero-knowledge property and combining identity attributes. Attribute-based encryption (ABE) is a new cryptographic primitive with additional functionalities in fine-grained access control mechanisms and one-to-many flexible encryption mode. However, most of the ABE schemes are not privacy-friendly. In this paper, we propose a privacy-friendly ABC system with ABE mode, which has several attribute revocation problems, privacy-friendly ABE scheme, flexible access control in ABC, data protection, and user authentications.
