A Cryptography Engineer’s Perspective on Quantum Computing Timelines
Recent research, including papers from Google and Oratomic, significantly lowers the estimated resources needed for quantum computers to break widely used 256-bit elliptic curve cryptography, suggesting such attacks could be feasible within just a few years. Given this accelerated timeline and expert warnings, Filippo Valsorda urges immediate deployment of post-quantum cryptography schemes, particularly lattice-based key exchanges and signatures, to mitigate an urgent and credible threat to current cryptographic security by as early as 2029.
