Adaptively secure key-policy ABE scheme with fast decryption

Adaptively secure key-policy ABE scheme with fast decryption

In the existing adaptively secure ABE (attribute-based encryption) schemes,the decryption cost goes linearly with the number of attributes that are used in decryption.An adaptively secure key-policy ABE (FKP-ABE) scheme with fast decryption is proposed,where constant size of computation overhead is...
