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.

Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
