A Low-Communication Garbled RAM from Homomorphic Secret Sharing External Inbox
Thursday, November 5, 2026, 4:30 – 5:30pm Garbling schemes are powerful tools in cryptography and secure two- or multi-party computation. However, classical garbled circuits do not efficiently support RAM programs with dynamic memory accesses.
In this talk, I will present a new approach to Garbled RAM based on recent succinct garbled circuit constructions. Our work enables dynamic data movement within succinct garbled circuits while achieving low communication costs. The construction relies on mild assumptions such as Decisional Diffie-Hellman or Ring Learning-With-Errors.
This is joint work with Jinye He and Wei-Kai Lin.
