Abstract
Disclosed is a network apparatuses, which makes it possible to effectively re-establish the cryptographic communication without increasing its processing burden and deteriorating the security aspects of them. The network apparatus that communicates with another network apparatus through a network to exchange cryptographic communication information including a key of cryptograph transmits, when a power off sequence is detected, a request for deleting the cryptographic communication information to the other network apparatus through a communication interface section, before a power source section is turned OFF so as to actually deactivate the network apparatus.
