Consider replacing KOS with Softspoken #24

Open mikelodder7 opened 1 month ago

mikelodder7 commented 1 month ago

If you read SoftSpokenOT: Communication--Computation Tradeoffs in OT Extension, we learn the KOS is deprecated. Softspoken OT is considered more secure and requires one less back and forth.

I don't see it deprecated but we had a task to add Softspoken OT as thats what the threshold BBS+ paper recommended.

The authors of DKLS "Note for DKLs19 + DKLs18 with Proactive Key Refresh (2019/1328): uses the KOS OT-extension protocol (2015/546), which we consider to be depricated (see 2022/192)."

I have looked in the 3 papers you mentioned and I don't find that statement. Can you please share the link you are reading from?

It's not a paper it's the authors website
