Statistical security parameter
Webλlog(T) elements for a statistical security parameter λ. On the other hand, [7] is statistically-sound (and the non-interactive proof inherits this security in the random oracle model), while the soundness of [50] relies on a new computational hardness assumption called adaptive root assump-tion. Like with the proof-size, [40] lies in-between ...

Web1 Answer Sorted by: 18 Computationally indistinguishable typically means that your adversary is computationally bounded and that because of this they cannot distinguish between, for example, two messages. For example, say you encrypt (with proper padding) the messages 0 and 1 using RSA and send them to the adversary. Webcosts are enhanced by a statistical security parameter. Kissner and Song [KS05] used polynomials to represent multi-sets. Letting the roots of Q X() and Q Y() coincide with elements of the multi-sets Xand Y. They observed that if r();s() are polynomials chosen at random then the roots of r() Q X() + s() Q Y() coincide with high probability with the
