Regulate Phone Attestation For Free

The attestation process uses a series of measurements that are unique to an enclave. You can use these measurements to create access policies in external services to grant the enclave access to special cryptographic operations.

Key attestation aims to provide a way to strongly determine if an asymmetric key pair is hardware-backed, what the properties of the key are, and what constraints are applied to its usage. ID attestation allows the device to provide proof of its hardware identifiers, such as serial number or IMEI.

Attestation, also called consular Attestation, refers to a consular practice ensuring authenticity of the very last signature or the seal affixed to a document related to the application from a natural person, legal person or other organization.

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.

If the device supports hardware-level key attestation, the root certificate within this chain is signed using an attestation root key that is securely provisioned to the device's hardware-backed keystore.

Setting SafetyNet attestation Log into the Admin Portal. Go to Policies & Configs > Policies. Select a security policy and click Edit. Alternatively, create a new security policy by clicking Add New > Security. Scroll down to the Android section. Select ?Require Google SafetyNet Attestation?.

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.

SafetyNet Attestation API ? Checks whether the gadget the application is attempting to run on is tampered or potentially compromised. It compares the device's profile with that of Google certified devices and verifies if the device or the software running on it is Android compatible.

The SafetyNet Attestation API provides a cryptographically-signed attestation, assessing the device's integrity. 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.
