Abstract:   The world's largest supercomputers are secretly operated computers attacking the foundations of e-commerce: for example, computing the secret factors of RSA-1024 public keys. Users can protect themselves by switching to larger key sizes, but this makes cryptography much more expensive.
Making rational choices requires understanding the abilities of a nation-state attacker, both now and in the foreseeable future.
However, this requires extrapolating far beyond computations that public researchers can actually carry out, posing unusually severe challenges in analyzing scalability and correctness of algorithms.
This session will highlight case studies of high-performance computing in cryptanalysis. Topics will include energy-optimized computations, alternative computing platforms, and the similarities and differences between cryptanalytic supercomputing and traditional supercomputing. Audience members are not required to have previous experience with cryptography or cryptanalysis.
