COMMUNICATION SYSTEM, ILLUMINATION SYSTEM, AND COMMUNICATION METHOD

WIPO Patent Application WO/2024/080100

A1

Provided are a communication system, illumination system, and communication method allowing realization of a device connection environment ensuring security without relying on a communication platform or user operation. A slave device (illumination device) generates a security code (A) to which a plurality of random data corresponding to address data are allocated, and a key code (A). In a first process after a communication connection has been established between the slave device and a master device (control device), the slave device transmits the key code (A) and the security code (A) to the master device, and the master device retains the key code (A) as a key code (B) and the security code (A) as a security code (B). In a second process after the first process, the master device transmits to the slave device an address code generated on the basis of the security code (B) and an XOR code (B) generated on the basis of the address code and a second key code, and the slave device cancels the communication connection with the master device if an XOR code (A) generated on the basis of the address code, the key code (A), and the security code (A) does not match the XOR code (B) received from the master device.
