Fast, Compact, and Expressive Attribute-Based Encryption
public key cryptography, pp. 3-33, 2020.
Attribute-based encryption (ABE) is an advanced cryptographic tool and useful to build various types of access control systems. Toward the goal of making ABE more practical, we propose key-policy (KP) and ciphertext-policy (CP) ABE schemes, which first support unbounded sizes of attribute sets and policies with negation and multi-use of a...More
