ABSTRACT:
Automatic configuration of devices upon introduction into a networked environment, can be implemented, for example, by having a device randomly generate a series of letters and/or numbers, e.g., generate a PIN (Personal Identification Number) that encodes temporary credentials that, in addition to proving ownership and/or control over the device by virtue of having access to the PIN, also allows creating a temporary secure communication channel based on the PIN over which permanent security credentials may be transferred to the device to facilitate provisioning it to securely communicate in the networked environment. In a wireless scenario, a unique SSID and encryption key (WEP or WPA) may be determined as a function of the PIN, where both the device and its access point utilize the PIN to establish a temporary secure communication channel. Various techniques may be used to establish ownership and/or control over the device to prevent inadvertent association of the device with a wrong networked environment.
