Abstract: Techniques include performing a calibration of the display with respect to the eye-tracking camera after usage. The calibration involves determining a current position of a reflected pixel of the display within a field of view of the eye-tracking camera and comparing that position with a calibration position, for example a position seen at the factory. The pixel may then be shifted according to the difference between the current position and the calibration position.

Abstract: One aspect provides a system and method for provisioning an access point (AP) in a wireless mesh network. During operation, a controller can obtain a set of published global encryption parameters comprising a master public key, apply an identity-based encryption (IBE) scheme to encrypt a configuration message based at least on the master public key, and transmit the encrypted configuration message to a proxy device, which forwards the encrypted configuration message to the AP. The proxy device is coupled to the controller via a previously established secure communication channel and coupled to the AP via an open communication channel. The AP can decrypt the encrypted configuration message using an AP-specific secret key generated based on a unique identifier of the AP and a master private key corresponding to the master public key, thereby facilitating provisioning of the AP based on the configuration message.
