Buterin warns AI advances could weaken lattice cryptography

Original: “So far most people have been in the mode of thinking ‘elliptic curves broken, hashes safe, lattices safe,’” he wrote. “

Ethereum co-founder Vitalik Buterin warned that many security experts assume only elliptic curve cryptography is at risk from quantum computing, while hash functions and lattice-based schemes remain safe. He cautioned that AI-driven mathematical breakthroughs over the next two years could seriously undermine the concrete security of lattice-based cryptography, calling this a major concern for post-quantum defenses.

Why now: His warning challenges the widespread assumption that lattice-based post-quantum cryptography is safe from AI-accelerated math breakthroughs.
