Cool demo, but this is only log2(43 quintillions) = 65 bit security.

Kind of related is DiceKeys, with 192 bit security: https://www.crowdsupply.com/dicekeys/dicekeys

192 bits?

I must be missing something here, there are 25 unique dice that can be permuted, each can have six potential sides showing, and 4 potential orientations of the displayed face... So (25!)×(25×6×4) ? Isn't that more like only 93 bits?

Well obviously harder to scan from a phone, I think a deck of playing cards would be easier to acquire and store. Shuffling 27 would give you 93 bits, shuffling the full 52 would be ~226.

It’s explained in the link. I actually misremembered, it’s 196 bits.

Yeah, this explains why this cryptography paper was published in a ML conference. Any reasonable reviewer would reject this as not providing sufficient security.

It's pretty upfront about being a novelty project done by a self-described non-crypto expert, and I don't see any assertions of it guaranteeing any degree of sufficiency/security or claiming any such NextBigThing(TM) hype.

Just because a paper is published doesn't mean it wasn't done for fun/the hell of it.
