I see, I heard about "fully homomorphic encryption" which is faster to implement and allows you to run code on encrypted data but the time complexity is O((10^6) * n) which is insane.

Confidential Computing also provides data-in-use protection and has a significantly more realistic overhead, often <10% in real-world workloads I've seen. However, in this case you might want to combine it with customer managed keys (BYOK) or self-hosting anyways - otherwise the customer has no opportunity to perform remote attestation and prove you're really running in Confidential Computing.

The visualization about halfway down https://www.anjuna.io/solution/secure-ai (my employer) is an example of the self-hosted flavor of this. Happy to discuss deeper, my contact info is in my bio.

> O((10^6) * n)

Isn't that O(n)? Is there a typo or am I missing something?
