Webschemes, we show the performance in the SXDH setting. Our schemes are instantiated with the Kiltz–Pan–Wee structure-preserving signature scheme from the SXDH assumption [6] and the Groth–Sahai proof system in the SXDH setting [5]. We also note that all the five schemes in this table are instantiated in prime order groups.
