INFORMATION PROCESSING DEVICE AND METHOD, RECORDING MEDIUM, AND PROGRAM

摘要

There is provided an information processing device capable of appropriately communicating with a communication partner according to a communication time with the partner. A reception control section (41) receives a random challenge (RC) from a terminal (11) of a transmission side and supplies it to a generation section (42). The reception control section (41) transmits an RC reception message indicating that an RC has been received, to the transmission side. The generation section (42) subjects the RC to hash processing and supplies the authentication data obtained as a result to a generation section (43). At a timing before receiving a response request command from the transmission side, a transmission control section (44) controls the generation section (43) so as to generate a response message containing authentication data corresponding to the response request command and, upon reception of the response request command, transmits the response message to the terminal of the transmission destination. The present invention can be applied to a content providing system.
