SOFTWARE-MANAGEMENT SYSTEM, RECORDING MEDIUM, AND INFORMATION-PROCESSING DEVICE |
摘要 |
A recording medium that is not easily tampered with and capable of avoiding invalid attacks on a communication channel between the recording medium and a terminal targeted for software installation, while being incapable of unauthorized updating of a correspondence relationship between software and license information. The recording medium includes a tamper-resistant module and an information- recording unit that has a normal storage area and a secure storage area. Software is recorded in the normal storage area, while a license count showing a permitted usage count of the software is recorded in the secure storage area in correspondence with signature data relating to the software. The tamper-resistant module performs mutual device authentication with the terminal, and if the license count in the secure storage area is within a predetermined value, outputs the software and the signature data to the terminal.
