Zusammenfassung:	According to one embodiment, in an encryption communication system, a first device and a second device that execute encryption communication via a first network share an encryption key used for the encryption communication via a second network including a plurality of nodes. The first device generates n pieces of first data used for generating the encryption key, transmits the n pieces of first data to the second device by distributing the n pieces of first data to n nodes among the nodes and sending the n pieces of first data to the second network, and generates the encryption key by using the n pieces of first data. The second device receives the n pieces of first data from n nodes among the nodes, and generates the encryption key by using the n pieces of first data.
