1. A device in a network where a plurality of devices are connected, the device comprising:
a storage disposed in a secure zone and configured to store a plurality of encryption algorithms, a plurality of information generators and a plurality of keys; and
an operation processor disposed in the secure zone,
wherein, when the device operates as a master device in the network, the operation processor is configured to:
(a) select, among the plurality of encryption algorithms, the plurality of information generators and the plurality of keys, at least one of an encryption algorithm, an information generator or a key to be used for encrypted communication within the network;
(b) generate profile information including at least one of identification information of the encryption algorithm, identification information of the information generator or identification information of the key; and
(c) transmit the profile information to another device among the plurality of devices in the network, and
wherein, when the device does not operate as the master device in the network, the operation processor is configured to:
(d) receive the profile information from the master device; and
(e) designate, based on the profile information, at least one of the encryption algorithm, the information generator or the key to be used for the encrypted communication.
