METHOD AND DEVICE FOR TRANSMITTING MESSAGE TO INDIVIDUAL RADIO DEVICE GROUPS

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for transmitting messages to individual radio device groups.

SOLUTION: It is determined whether or not one of messages is a predetermined message for finding a device on a network. Based on the result of the determination, the message is encrypted using a key corresponding to at least one of groups including devices on the network, and the resulting message is transmitted. Thereby, a guest radio device which is not known to a user is prevented from finding a user's home radio device without permission by the user.
