Cryptographers Urge Frontier Labs to Publish Negative Results on Code-Breaking

matthew_d_green · x · 2026-10-10

Cryptographer Chris Peikert, echoing Matthew Green, argues the most valuable thing frontier labs can do for cryptography is publish their negative results: which ideas they tried, how much compute they spent, and what obstacles they hit. Green adds that silence is the worst thing labs can publish right now.

The discussion highlights a core concern: whether AI is nearing the boundary of breaking existing cryptography, and how lab opacity on failed attempts leaves outside researchers unable to judge the situation.
