Abstract:
1. A transmitting device for creating a secure wireless communication network of a limited area, comprising: one or more transmitters configured to transmit wireless signals, and create the limited area by a coverage scope of the wireless signals; a cryptography key generator configured to generate a cryptography key for the wireless signals; a cryptography key encoder configured to encode the cryptography key to a cryptography key frame; and a cryptography key scheduler configured to schedule the cryptography key frame so as to control the transmitter to transmit the wireless signals including the cryptography key frame to one or more nodes within the coverage scope of the wireless signals, wherein the wireless signals are infrared signals and a node is within the coverage scope of the wireless communication network where a receiving power of the node is greater than a threshold power.
