Post-Quantum Oblivious Transfer from Smooth Projective Hash Functions with Grey Zone. (arXiv:2209.04149v1 [cs.CR])

Oblivious Transfer (OT) is a major primitive for secure multiparty
computation. Indeed, combined with symmetric primitives along with garbled
circuits, it allows any secure function evaluation between two parties. In this
paper, we propose a new approach to build OT protocols. Interestingly, our new
paradigm features a security analysis in the Universal Composability (UC)
framework and may be instantiated from post-quantum primitives. In order to do
so, we define a new primitive named Smooth Projective Hash Function with Grey
Zone …
