How many comminication bits in OT-based bit triple generation exactly?

de flag

I'm really confused about concrete communication in OT-based bit triples generation. In paper CCS20-CrypTFlow2 A.1, the author describe how to generate 2 pairs of bit triples with an instance of 1-out-of-16 OT with length 2, which communicate k+16=144 bits for each pair. However, the original paper to give this idea NDSS17 3.5 summarize this result as 134 bits for each pair. Q1. Which one is ture actually, and how is this number 134 calculated? Q2. When calculate the concrete number, I find papers use 2k+nl sometimes and k+nl sometimes, why? Q3. In paper KK13, the author stated that the security parameter should be about twice as much as security parameter in IKNP03, didn't we need to take this into consideration when doing the calculation? Thanks.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
