I've been working on something related for fair salary negotiations, where the two parties think of their honest salary proposal, exchange random numbers and exponents with each other, perform some arithmetic using the random number and their own secret honest salary number, and then decide whether the result is acceptable to both. I started hacking on this protocol using a pencil and paper variation of Diffie-Hellman where instead of a secret key agreement you arrive at the same salary number (as a function of the difference in your secret numbers), but realized you can do a one-sided version of this where the potential employee says to the recruiter "think of your max budget for this role" using a variation the second puzzle in article, though unfortunately the recruiter would likely feel tricked, so I've gone back to working on a DH-like protocol ahead of time because it would be fairer. Of course I would have liked to have made a blog post out of it, but this article is so close and mine is still half-baked, so if someone beats me to it and wants to leverage the power of being wrong on the internet in this comment thread, we could create a fair protocol that improves the lives of all parties involved in the hiring process.
