Fully Key-Homomorphic Encryption, Arithmetic Circuit ABE and Compact Garbled Circuits
We construct the first (key-policy) attribute-based encryption (ABE) system with short secret keys: the size of keys in our system depends only on the depth of the policy circuit, not its size. Our constructions extend naturally to arithmetic circuits with arbitrary fan-in gates thereby further redu...
