Fit Phone Attestation For Free

Device attestation refers to the identification and authentication of a device based on its configuration and known operating state. Device attestation can be determined via a cryptographic hash of the device.

Attestation is a mechanism for software to prove its identity. The goal of attestation is to prove to a remote party that your operating system and application software are intact and trustworthy. The verifier trusts that attestation data is accurate because it is signed by a TPM whose key is certified by the CA.

With Managed Device Attestation, a device provides strong evidence about itself when making a request. It improves posture information, so trust evaluations based on that are more accurate. In short, Managed Device Attestation means legitimate devices reliably access resources, and attackers are thwarted.

To remedy this, Keymaster introduced key attestation in Android 7.0 (Keymaster 2) and ID attestation in Android 8.0 (Keymaster 3).
