Abstract
Methods and systems for performing wireless communication are presented. In one example, a wireless peripheral device comprises a wireless transceiver configured to receive and transmit data over a primary channel, an optical sensor configured to receive data over an out-of-band channel, and one or more processors configured to: receive, via the wireless transceiver and over the primary channel, wireless signals including first key data from a second device; receive, via the optical sensor, optical signals including verification data from the second device; verify the first key data based on the verification data; and responsive to verifying the first key data based on the verification data, generate a digital security key based on the first key data, the digital security key used for following data transmission between the wireless peripheral device and the second device via the wireless transceiver.
