Abstract:
1. A computer-implemented method for verifying the authenticity of a device, the method comprising: requesting from the device a device identifier, application data and a proof of possession that is derived from a device key and the application data; receiving the device identifier, application data and the proof of possession from the device; generating via a first cryptographic algorithm a derived device key based on the device identifier and a master key; generating via a second cryptographic algorithm a derived proof of possession based on the application data received from the device and the derived device key; determining whether the derived proof of possession matches the received proof of possession; and if the derived proof of possession matches the received proof of possession, then verifying the authenticity of the device, or if the derived proof of possession does not match the received proof of possession, then not verifying the authenticity of the device.
