Webproportional to the size of the circuit. In contrast, FHE requires very small communication, proportional to the security parameter, and independent of the circuit size (while paying in high computation complexity). However, for many neural networks considered here and in other works, we are able to obtain garbled circuits whose size is quite ...

Webthe circuit in the worst-case). This blowup can be avoided via computational assump-tions (specifically, the existence of quantum-secure pseudorandom generators). In the computational case, the size of the encoding is proportional to the size of the circuit being garbled, up to a polynomial in the security parameter.
