With RKP, when a device fails to provide valid attestation keys (e.g., after bootloader unlocking), it can request new keys remotely. This is handled by the com.android.rkpdapp system service, which communicates with Google's provisioning servers.

The release modernizes XML key management with strong encryption, better performance, and clearer API semantics. While not a zero-effort upgrade, the security and maintainability gains justify migration. Teams should test the new streaming parser with their largest keyboxes before production rollout.
The standard introduces keybox chaining —a single device can have multiple keyboxes, with the attestation server selecting the most recent, unrevoked one. This allows OEMs to push over-the-air (OTA) updates that replace compromised keyboxes without a full system rewrite.
