A providing apparatus provides information required for secure
communication to first and second devices. The providing apparatus
includes a receiving unit that receives a first parameter used by the
first device for the secure communication and a second parameter used by
the second device for the secure communication from a connection
apparatus via which the first device is connected to the second device, a
generating unit that generates the information required for the secure
communication based on the parameters received from the connection
apparatus, and a transmitting unit that transmits the information
required for the secure communication, generated by the generating unit,
to the first and second devices.
