CROSS — Leveraging AI ASICs for Homomorphic Encryption

The talk presents CROSS and Morph, two compiler frameworks that enable existing AI accelerators, like Google's TPUs, to efficiently execute cryptographic workloads. CROSS focuses on Homomorphic Encryption (HE) and Morph on Zero-Knowledge Proofs (ZKP), demonstrating how to transform high-precision modular arithmetic into low-precision matrix operations that TPUs excel at, thereby achieving state-of-the-art performance and energy efficiency without any hardware modifications.
