Encrypted AI inference and CDN privacy #110
Today's Letter
Google, HEIR compiler for private AI inference
- Google introduced HEIR, an open-source compiler toolchain for homomorphic encryption
- HEIR converts pretrained AI models to run inference on encrypted inputs
- Servers can process ciphertexts and return encrypted results without accessing underlying data
- Demonstrations cover private recommendations, credit-card fraud detection, encrypted-traffic intrusion detection, and hotword detection
- Examples were compiled for single-threaded CPU execution, with source code available on GitHub
- Google says homomorphic encryption adds computational overhead while enabling cryptographic privacy
- HEIR has supported four peer-reviewed publications and collaborations with universities and hardware accelerator companies

Vercel CDN, Encrypted Client Hello Support Added
- Vercel CDN now supports Encrypted Client Hello (ECH) for domains managed by Vercel DNS
- ECH encrypts the Server Name Indication (SNI) in the TLS handshake
- Network observers see a connection to Vercel’s shared ECH hostname, vercel-ech.com
- ECH is managed at the platform level and enabled automatically where supported
- Recent versions of Chrome, Edge, and Firefox support ECH
