Abstract
A wireless device that desires to be connected to a wireless network broadcasts itself and its capabilities to a network using an information element. The information element is provided with frames, such as management frames, in a channel that is not protected or encrypted. The information element is forwarded to one or more potential registrar devices. One of the registrar devices then provides configuration information to the enrollee, for example as a registrar information element. The configuration information may be passed out of band or in band, and may be passed using cryptography, which may involve public key cryptography, encryption with a PIN, or some other type of secure exchange.
