Obtaining a configurator public key for authentication

A configurator comprising:

• a wireless interface to communicate wirelessly with an electronic device;
• and
• a hardware processor to:
• receive, through the wireless interface, a first message containing a device identifier of the electronic device, the first message sent by the electronic device to discover a wireless network;
• in response to the first message, obtain a first key correlated to the device identifier;
• encrypt a configurator public key with the first key to derive an encrypted configurator public key;
• send, through the wireless interface, a second message containing the encrypted configurator public key to the electronic device;
• and
• perform an authentication process with the electronic device based on a decrypted version of the encrypted configurator public key.

A non-transitory machine-readable storage medium comprising instructions that upon execution cause a configurator to:

• receive a first message sent by an electronic device to discover a wireless network, the first message containing a device identifier of the electronic device and encryption algorithm information specifying an encryption algorithm;
• in response to the first message, obtain an enrollee key correlated to the device identifier;
• encrypt a configurator public key with the enrollee key using the encryption algorithm specified by the encryption algorithm information to derive an encrypted configurator public key;
• send a second message containing the encrypted configurator public key through a wireless interface to the electronic device;
• and
• perform an authentication process with the electronic device based on a decrypted version of the encrypted configurator public key.
