Authentication of a device

A first device comprising:

• a memory;
• and
• a processing device, operatively coupled with the memory, to:
• receive a request to initiate pairing between the first device and a second device using pairing data, wherein the pairing data comprises a first value and a second value, the second value comprising first challenge data;
• send second challenge data to the second device;
• generate an output value based on a key of the first device and the first challenge data;
• generate a first cryptographic proof based on the output value and the second challenge data;
• send the first cryptographic proof to the second device for authenticating the first device with the second device by comparing the first cryptographic proof with a second cryptographic proof, generated by the second device, based on the pairing data;
• and
• receive an indication that the pairing is complete in response to the first cryptographic proof matching the second cryptographic proof.

A non-transitory computer readable medium including data that, when accessed by a processing device of a first device, cause the processing device to perform operations comprising:

• receiving a request to initiate pairing between the first device and a second device using pairing data, wherein the pairing data comprises a first value and a second value, the second value comprising first challenge data;
• sending second challenge data to the second device;
• generating an output value based on a key of the first device and the first challenge data;
• generating a first cryptographic proof based on the output value and the second challenge data;
• sending the first cryptographic proof to the second device for authenticating the first device with the second device by comparing the first cryptographic proof with a second cryptographic proof, generated by the second device, based on the pairing data;
• and
• receiving an indication that the pairing is complete in response to the first cryptographic proof matching the second cryptographic proof.
