Abstract
-
Our construction for reusable garbled circuits for \(\mathsf{NC}_1\) achieves the optimal “full” simulation based security.
-
The ciphertext of our scheme can be divided into a succinct data dependent component and a non-succinct data independent component. This makes it well suited for optimization in an online-offline model that allows a majority of the computation to be performed in an offline phase, before the data becomes available.
