Efficient Privacy-Preserving Ciphertext-Policy Attribute Based-Encryption and Broadcast Encryption
IEEE Trans. Computers, pp. 126-138, 2015.
Ciphertext Policy Attribute-Based Encryption (CP-ABE) enforces expressive data access policies and each policy consists of a number of attributes. Most existing CP-ABE schemes incur a very large ciphertext size, which increases linearly with respect to the number of attributes in the access policy. Recently, Herranz proposed a constructio...More
