Large Universe Subset Predicate Encryption Based on Static Assumption (without Random Oracle)
Predicate Encryption Adaptive Security Standard Model
2018/12/11
In a recent work, Katz et al. (CANS'17) generalized the notion of Broadcast Encryption to define Subset Predicate Encryption (SPE) that emulates \emph{subset containment} predicate in the encrypted do...
Practical Attribute-Based Encryption: Traitor Tracing, Revocation, and Large Universe
Attribute-Based Encryption Traitor Tracing Revocation
2016/1/8
In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user's decryption key is associated with attributes which in general are not related to the user's identity, and the same set of attributes ...
Efficient Statically-Secure Large-Universe Multi-Authority Attribute-Based Encryption
Attribute-Based Encryption Multi-Authority Large Universe
2016/1/5
We propose an efficient large-universe multi-authority ciphertext-policy attribute-based
encryption system. In a large-universe ABE scheme, any string can be used as an attribute of the system,
and ...
