WebXOR Filter. Available as 8-bits and 16-bits fingerprint length. A XOR Filter is a better space-efficient probabilistic data structure than Bloom Filters. Very usefull for space efficiency of readonly sets. Reference: Graf, Thomas Mueller, and Daniel Lemire. "Xor filters: Faster and smaller than bloom and cuckoo filters." WebOur results build on a simple and powerful combination of techniques that were introduced in previous works in several contexts. In particular, our garbling scheme is based on a natural generalization of the Free-XOR technique of Kolesnikov & Schneider [KS08], allowing for free addition mod larger m, rather than just mod 2.

WebDoes it really matter if we used AND, OR or XOR with the one-time pad? The answer is yes, and it’s extremely important to understand why. Recall from the previous article that AND has a 75% chance of outputting 0 and a 25% chance of outputting a 1. While OR has a 25% chance of outputting 0 and 75% chance of outputting 1. Webin combination with free-XOR. We prove the security of our scheme in Section 4. For all circuits, our half-gate technique leads to smaller garbled circuits than all previous methods (i.e., our row of Table 1 dominates all other rows). For many circuits (i.e., those for which free-XOR previously gave the smallest garbled circuits), our work
