Abstract
If the communication partner of a client node (A1a) is an encryption communication target node (C1), a DNS Proxy unit (A12a) in the client node rewrites a response to a name resolution request for the communication partner node of an application from the actual IP address of the communication partner node to a loopback address that changes depending on the communication partner. On the basis of the destination loopback address of a data packet transmitted from the application, a communication encryption module (A13a) in the client node identifies the communication partner and the encryption communication path to be used for communication with the communication partner. Hence, encryption communication can simultaneously be executed directly with a plurality of communication partner nodes by using the communication encryption module that operates as an independent process.
