Cipher Text Policy Attribute-Based Encryption Supporting Flexible Attributes
نویسنده
چکیده
Ciphertext Policy Attribute-Based Encryption (CP-ABE) has been a very active research area in recent years. Because of two properties traceability and large universe, CP-ABE is enriching the commercial applications. But to achieve this it requires more computation overhead. In this paper a novel approach for construction of efficient ciphertext policy ABE supporting flexible attributes is proposed, which helps to reduce the computation overhead and improves security by providing privacy preserving data access policies. Keywords— Attribute-Based Encryption, Ciphertext Policy, Privacy, Traceability.
