Episode notes
In this episode, Anna Rose and Tarun Chitra chat with Sora Suegami and Enrico Bottazzi from Machina iO. They explain indistinguishability obfuscation (iO) technology and how they are working to bring this powerful cryptographic primitive from theoretical territory into the practical world. They discuss how the pair got into iO and how new assumptions like all-product LWE and evasive LWE will help bridge theory to practice.
They explore the benchmarks, the challenges and opportunities of this cutting-edge privacy cryptography and cover potential optimizations and real-world uses. While iO is still far from being truly practical, their work shows tangible steps ahead and offers interesting insights into how this could actually work.
