Edge Security & Attestation advanced
A fleet platform decides to require a fresh hardware attestation on every device connection. The gateway issues a nonce, the device returns a boot measurement signed inside its secure element, and only measurements on an allow-list are admitted. The team gets replay resistance and firmware integrity. What have they given up, and when does that bill arrive?

In June 2024 Apple described Private Cloud Compute, where a user's device will only send a request to a server node that cryptographically attests to running a specific software image, and the device checks that measurement against a public append-only transparency log before sending anything. What problem does this solve that signed code and audits do not, what does it cost, and where would copying it be a mistake?
