Interview question · Cryptography, PKI & TLS

What do confidential computing and attestation actually buy you for model inference?

Trusted execution moves the trust boundary from the operator to the hardware and the attested code. The scored answer is precise about what that protects, what it assumes, and what it leaves open.

What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

A healthcare customer wants to run inference on sensitive data in the cloud without the provider being able to see it.

  1. What is confidential computing?
  2. How does the customer know the environment is genuine?
  3. What does it not protect against?
  4. What are the practical costs?
  5. How would you design the service?
  6. What would you propose to the customer?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
