Learn about a research presentation from PriSC 2025 that introduces ILA, a correctness-oriented intermediate representation for type-checking fully homomorphic encryption (FHE) circuits. This 26-minute video features Tarakaram Gollamudi, Anitha Gollamudi, and Joshua Gancher presenting their work on addressing critical challenges in FHE implementation. Discover how their type system tracks quantitative bounds like ciphertext noise without requiring the secret key, proving a strong functional correctness criterion for FHE circuits. The presentation explains how ILA is designed to be scheme-agnostic while demonstrating its application with the BGV scheme. See how their implemented static type checker can detect noise overflows and optimally place modulus switching operations to reduce noise. The research shows promising results with sound detection of noise overflows and practical, tight noise estimates, making FHE application development less error-prone.
