Interactive Table Attestation For Free

The Integrity API unifies Google Play anti-abuse features with a collection of integrity signals to help Android app and game developers detect potentially risky and fraudulent traffic. This traffic could come from modified versions of your app or game, untrustworthy devices, or other untrustworthy environments.

Attestation is a kind of testimony or confirmation. It is customary to sign a deed, make a will or sign other written documents in the presence of a witness who also signs the document to attest to its contents and the authenticity of the party's signature.

Remote attestation is a method by which a host (client) authenticates it's hardware and software configuration to a remote host (server). The goal of remote attestation is to enable a remote system (challenger) to determine the level of trust in the integrity of platform of another system (attestator).

For example, App Attest can't definitively pinpoint a device with a compromised operating system. Instead, the DeviceCheck services provide information that you can integrate into an overall risk assessment for a given device.

In order to create the attestation, the API examines the device's software and hardware environment, looking for integrity issues, and comparing it with the reference data for approved Android devices. The generated attestation is bound to the nonce that the caller app provides.

This attestation provides assurance that the properties of the device (for example, the serial number) are legitimate (as attested to by the device's Secure Enclave and verified by Apple's servers) and not spoofed.

By matching the fingerprint to a trusted application, the attestation document can authenticate the application's identity, guaranteeing that the running instance is unmodified and trustworthy.

Google's servers send the signed attestation to the SafetyNet Attestation service on the device. The SafetyNet Attestation service returns this signed attestation to your app. Your app forwards the signed attestation to your server. This server validates the response and uses it for anti-abuse decisions.

In the MobileIron Core Admin Portal, you can enable Google SafetyNet attestation on Android devices to verify the integrity of the devices' software and hardware. This action provides Core with the devices' SafetyNet attestation status. With this status, you can: ? Take actions on untrusted devices.

How does TPM key attestation work? In general, TPM key attestation is based on the following pillars: Every TPM ships with a unique asymmetric key, called the Endorsement Key (EK), burned by the manufacturer. We refer to the public portion of this key as EKPub and the associated private key as EKPriv.
