METHOD AND APPARATUS TO DISTRIBUTE AN ACCESS CREDENTIAL TO MULTIPLE DEVICES USING ULTRASONIC COMMUNICATION

摘要

A method to distribute an access credential to multiple devices using ultrasonic communication includes a master device receiving the number of slave devices to receive the access credential and determining a distribution sequence for ultrasonic distribution communication between the master device and the plurality of slave devices. The access credential is divided into multiple credential chunks and one of the credential chunks is transmitted to each of the slave devices using the distribution sequence. The slave devices then share the credential chunks according to the distribution sequence and reconstruct the access credential which can then be used by the slave devices to access a wireless network.

1. A method to distribute an access credential to multiple devices using ultrasonic communication, the method comprising:
determining, by a master device, a distribution sequence for ultrasonic distribution communication between the master device and a plurality of slave devices; dividing, by the master device, the access credential into credential chunks; transmitting, by the master device using ultrasonic communication, one credential chunk to each of the plurality of slave devices using the distribution sequence; sharing credential chunks between the plurality of slave devices according to the distribution sequence; and transmitting, by the master device using ultrasonic communication, a reconstruction sequence from the master device to the plurality of slave devices; reconstructing the access credential by the slave devices; and using the reconstructed access credential by one of the plurality of slave devices to access a wireless network.
