<p><P>PROBLEM TO BE SOLVED: To provide an application on a computing device for writing data in a recording medium related to the computing device. <P>SOLUTION: Data are written into a storage region protected by security related to an object on the recording medium, and the security-protected storage region has a related value storage region. The application generates nonce, encodes the nonce using a common session key (KS) for bringing about (KS (nonce)). The recording medium receives (KS (nonce)), uses (KS) for decoding (KS (nonce)) for bringing about nonce, specifies the value storage region related to the security-protected storage region, and stores the nonce in the specified value storage region. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
