Claim of US Patent No. 10,169,587

8. A method for conducting a device provisioning protocol (DPP), the method performed by a mobile phone, the method comprising:operating, by the mobile phone, a DPP application, wherein the DPP application comprises an initiator for the device provisioning protocol;
establishing, by the mobile phone, a secure session with a server, wherein the secure session comprises at least, in part, authentication of the DPP application;
receiving, by the mobile phone and from a device, a tag value for a responder;
sending, by the mobile phone and to the server, the received tag value;
receiving, by the mobile phone and from the server, an initiator configuration, wherein the mobile phone uses the received initiator configuration with a WiFi radio in the mobile phone;
receiving, by the mobile phone and from the server, an initiator ephemeral public key and a first ciphertext, wherein the first ciphertext includes an initiator nonce;
sending, by the mobile phone and to the device, the initiator ephemeral public key and the first ciphertext, wherein the mobile phone uses the received initiator configuration to send the initiator ephemeral public key and the first ciphertext to the device;
receiving, by the mobile phone and from the device, a responder ephemeral public key and a second ciphertext, wherein the second ciphertext includes a responder authentication value;
sending, by the mobile phone and to the server, the responder ephemeral public key and the second ciphertext; and,
receiving, by the mobile phone and from the server, a third ciphertext, wherein the third ciphertext includes a set of network credentials for the device.
