Zusammenfassung:According to one embodiment, an encryption communication system configures a network with a plurality of nodes, and shares the encryption key between a first node (131) that delivers the encryption key to a first user (11) and a second node (132) that delivers the encryption key to a second user (12). The first node (131) forms n (n > 1) systems of paths to the second node (132) over the network, generates n pieces of first data, distributes the n pieces of first data to the n systems of paths and transmits the n pieces of first data to the second node, and generates the encryption key by superimposing the n pieces of first data. The second node (132) receives the n pieces of first data from the first node (131) via the n systems of paths, and generates the encryption key by superimposing the n pieces of first data.
