Can you convincingly lie to a fellow leader with a straight face, in front of the crowd of other European leaders? Perhaps you wish to obfuscate or encrypt your messages. Or say nothing at all.

“Global press - Tabletop negotiations”

There remain a few more open seats at the table!

For encryption I recommend the technique I laid out on the strategy board. It's a way to agree to a common secret in the public press. It remains secret because it is a mixture of 3 ingredients: 2 secret ones, one from each party,
and 1 such that either secret can be mixed to it before the other. I call it the confounding factor.

In the following table
- CF is the confounding factor
- S1 is the secret of Player 1
- S2 is the secret of Player 2
- * means mixing

Code: Select all

Player 1 knows |  Public Press  | Player 2 knows
---------------+--------------------+-----------
S1           <-+--     CF     --+->           S2
S1*CF        --+->    S1*CF   --+->     S1*CF*S2
S1*CF*S2     <-+--    CF*S2   <-+--        CF*S2
The common secret is S1*CF*S2. S1*CF and CF*S2 are the confounded secrets of respective players. In theory S1 and S2 could be recovered from the mix, but that is extraordinarily difficult because the mixture is restricted to a finite field with wraparound to fail preconditions that made it easy in the realm of integers.

This can be done with tools that are readily available on most UNIX-like systems. For convenience I wrote a makefile.

Kidding aside, I'd absolutely play, but there's no way I could commit to those fast of turns. If you bumped it to 48 hour turns, I'd be in.
