Google is making private AI practical with homomorphic encryption

Google has introduced HEIR, an open-source compiler within its Private Computing Toolkit, designed to enable cryptographically-secure private AI inference. Since its announcement in 2023, HEIR has fostered collaborations with hardware accelerator developers like Belfort and Cornami, and academic institutions including Georgia Tech and Tsinghua University. This has led to several peer-reviewed publications and numerous citations, demonstrating its role as a productive research platform. Google aims to make homomorphic encryption easy to develop, fast to run, and ubiquitous across the industry.
