I'm now reading this paper. I got how to reduce an OT cost.
OT extension is a method that replaces a OT with many base-OTs.
But I'm not still sure how to implement each base-OT.



How can we do that?
Any references? I prefer more recent construction.
Thank you.

          You can take a look at LibOT, which is a C++ implementation of several OT extension protocols.
          In the Readme you can find a list with many base and extension Oblivious Transfer protocols.



          A protocol that people use a lot is the Simplest OT (although it was announced that the security proof has a bug by one of the authors at the TPMPC2018 workshop).



          Another popular option is PVW, the protocol by Peikert, Vaikuntanathan and Waters.
          It has two variants.
          One DDH-based and another LWE-based.
          The first one is particularly easy to understand and implement.

                    One-line joke

                    A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
