Wow- treating a hash function as if it’s random is standard in cryptography. We always knew that it is not 100% theoretically justified and there were works (also by me) with contrived counter examples. This is the first time there is an attack on a standard protocol that’s

Really nice work. I've suspected for a while that a result like this would hold but I'd never been able to show it. Congrats to Dmitry, Ron and Lev! I imagine a natural direction now is to see if this attack can be extended to other argument systems?

This is insanity, the guy is a *legal permanent resident*. theguardian.com/us-news/2025/m…

Maybe Khalil is not a nice guy. Maybe he’s an antisemite. Maybe he supports Hamas. But the point of fighting against organizations like Hamas is to protect our freedom as Americans. If he committed a crime then let him be charged. But a country in which the government can
