Document Type and Number:
Japanese Patent JP7122586
Kind Code:
B2
Abstract:
An intercom system includes an electronic lock of an entrance door, an entrance slave device, an intercom master device, and an authentication server. An authentication server establishes a first encryption communication path between the authentication server itself and the intercom master device, establishes a second encryption communication path between the authentication server itself and the wireless terminal, and relays communication between the intercom master device and the wireless terminal. With the initial settings, the intercom master device registers the wireless terminal with the intercom master device itself, performs an exchange of key information with the wireless terminal, and establishes a third encryption communication path between the wireless terminal and the intercom master device itself. The wireless terminal transmits an instruction to unlock the electronic lock to the intercom master device through the first encryption communication path, the second encryption communication path, and the third encryption communication path.
