Questions about ocelot choices

[dnat112]

I'm to understand the rational for ocelot's implementation choices.

Is there any reason why ocelot does not implement the IKNP OT Extension?

Why does ocelot implement two OT extensions that use Chou-Orlandi as the base OT (as listed in swanky/ocelot/src/ot/mod.rs ) but none that use Naor-Pinkas as the base OT?

Thank you!

@dnat112 , ocelot imlements KOS15 OT extension which is IKNP+malicious security.

To answer your second question, maybe because Chou-Orlandi is maliciously secure and thus is given preference over the semi-honest Naor-Pinkas.
