Abstract:
Methods, devices, systems, and non-transitory process-readable storage media for using secure elements to authenticate a data source device for providing reporting data to a recipient device via local point-to-point communications. An embodiment method includes operations performed by a secure processor of a recipient device that include generating a random token, a data encryption key, and a control register, encrypting the generated data using a shared encryption algorithm and a secret key associated with a unique identifier of the data source device, decrypting data re-encrypted by the data source device and sent within a response message using the shared encryption algorithm and the secret key, determining whether decrypted data matches the random token, and identifying the data source device is authenticated in response to determining that decrypted data matches the random token. The unique identifier and secret key may be pre-loaded on the recipient device.
