WebIn this work, we propose new circuit-based protocols for computing variants of the intersection with an almost linear number of comparisons. Our constructions are based on new variants of Cuckoo hashing in two dimensions. We present an asymptotically efficient protocol as well as a protocol with better concrete efficiency.
