Provided are a communication system, a relay apparatus, and a communication method capable of achieving high security in a case of controlling devices such as electric power meters and acquiring data from the devices by connecting an autonomous distributed near field communication network such as a smart utility network to a public radio communication network. A relay apparatus 100 establishes a radio bearer with security ensured with a radio base station 40 by using a secret key associated with the relay apparatus 100 in the public radio communication network. Then, the relay apparatus 100 acquires a secret key associated with the terminal device 200A via the radio bearer from an HSS 50, and executes security setup processing including authentication of the terminal device 200A by using the acquired secret key. |
