    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.

    Abstract translation: 方法，设备，系统和非暂时过程可读存储介质，用于使用安全元件来认证数据源设备，以经由本地点对点通信向接收方设备提供报告数据。 实施方式包括由接收方设备的安全处理器执行的操作，其包括生成随机令牌，数据加密密钥和控制寄存器，使用共享加密算法和与唯一标识符相关联的秘密密钥对所生成的数据进行加密 数据源设备，解密由数据源设备重新加密并在使用共享加密算法和秘密密钥的响应消息内发送的数据，确定解密的数据是否与随机令牌匹配，以及识别数据源设备以作出响应 以确定解密的数据与随机令牌匹配。 唯一标识符和秘密密钥可以预先加载到接收设备上。
