Today’s Sharp Thought: Homomorphic Encryption is hot to go

Summary

The piece is prompted by Apple’s paper on applying Homomorphic Encryption (HE) to Apple Intelligence — the first high-profile deployment of HE outside data clean rooms. HE allows computation on encrypted data without decrypting it, which addresses the core tension between sending sensitive context to an AI model and keeping that data private. The author treats Apple’s move as a signal that HE is crossing from a niche privacy technique into mainstream AI infrastructure.

Implications

• Feeds the MCP at enterprise scale thread: enterprise adoption of AI agents stalls wherever sensitive data cannot leave the perimeter; HE is a candidate architecture for letting cloud inference run on data that must stay encrypted, which would unblock regulated industries.
• Relevant to the Mythos / Project Glasswing thread: the government and intelligence agencies’ cautious approach to Anthropic’s models reflects exactly the problem HE addresses — can a frontier model be used on sensitive data without exposing that data to the model provider?
• If HE performance continues improving (Apple’s paper is early signal), it changes the architecture calculus for private agent infrastructure: local-first stops being the only option for sensitive workloads.
