摘要

PROBLEM TO BE SOLVED: To select the optimal encryption communication mode taking throughput and cost into consideration according to a request of an application.SOLUTION: A communication device to be connected to a key generating device generating an encryption key comprises an inquiry unit, an encryption processing unit, and a selection unit. The inquiry unit inquires the key generating device of capability information indicating capability by which the key generating device generates an encryption key. The encryption processing unit executes a plurality of encryption functions. The selection unit selects an encryption function according to the capability information from the plurality of encryption functions. The encryption processing unit executes the encryption function selected by the selection unit.
