We present a new methodology for realizing Ciphertext-Policy Attribute Encryption (CP-
ABE) under concrete and noninteractive cryptographic assumptions in the standard model. Our
solutions allow any...
In ciphertext policy attribute-based encryption (CP-ABE),
every secret key is associated with a set of attributes, and
every ciphertext is associated with an access structure on
attributes. Decrypt...
