Then, (subexponentially secure) indistinguishability obfuscation for all polynomial-size circuits exists. Assuming only polynomial security of the assumptions above yields polynomially secure functional encryption for all polynomial-size circuits. WebSpecifically, we show how to adapt the recent DLIN-based instantiations of Lewko (Eurocrypt ’12) to the SXDH assumption. To our knowledge, this is the first work to instantiate either dual system encryption or dual pairing vector spaces under the SXDH assumption.
