Abstract: The present disclosure generally relates to communicating data. Some techniques are described herein for selecting an initiator for a near-field communication (NFC). Such techniques include comparing a random number generated to a random message received in a polling message to select an initiator for NFC. NFC is then used to transfer data to be used to establish a different type of wireless communication channel, such as Wi-Fi or Bluetooth. Other techniques are described herein for selectively sending a long-term key over one communication channel for another communication channel when communicating with another device. Such techniques include receiving an authentication credential from the other device and, if the authentication credential has not previously been seen, sending the long-term key. Other techniques are described herein for selectively delaying subsequent communication with another device communication over a communication channel. Such techniques include receiving an authentication response from the other device and, if the authentication response corresponds to an unknown device, delaying subsequent communication with the other device.
