How does com.samsung.android.knox.attestation help with device security

When verifying devices as Samsung devices, it’s important to note that certificate change alone isn’t enough to prove that a device is a Samsung device since malicious attackers can send a certificate chain generated by other devices.

With SAK, it’s injected during the manufacturing process of a Samsung device to ensure it’s protected by secure hardware.

When verifying devices as Samsung devices, the attestation certificate chain is validated, which contains a hash value that includes the device IMEI and serial number.

This hash value is embedded as the unique identifier (UID) in the subject field, which is then used to prove the device ID hasn’t been changed after the SAK certificate has been generated.

How Does Samsung Knox Attestation Work?

With Knox Enhanced Attestation, device integrity can be validated on-demand by a remote Samsung Attestation server.

When an attestation request is made:

  1. The device side Knox Enhanced Attestation agent uses the Keystore attest API to receive an attestation certificate chain paired with an application private key.
  2. The attestation certificate chain is used by apps for validation, which consists of:
    • The attested key certificate — A certificate of the application key stored and managed in the Keystore.
    • The attestation certificate — The certificate of SAK. The attestation key is used to sign the attested key certificate.
    • The root certificate — The certificate of the root key issuing the SAK certificate, which is the last component of the attestation certificate chain.
  3. The Knox Warranty Bit value is checked to determine if a device has been rooted.
  4. The Knox Enhanced Attestation agent combines proprietary data to produce an attestation verdict, which indicates if tampering is suspected.

The attestation verdict is sent to the requesting web server on the TLS connection between the Samsung Attestation Server and the partner’s web server.

This process ensures the attestation verdict is secured during transfer to protect it from being modified.

If device tampering is suspected, security measures may include:

  1. Uninstalling apps from the device,
  2. Erasing sensitive data,
  3. Checking the device location, or simply logging the event for later action.
