Storage apparatus access control apparatus for a recording medium, and access control method for a recording medium

摘要

A storage apparatus includes a recording medium 40 on which a coded password XW1, generated by coding a password assigned to a user using a coding algorithm (one-way function) is recorded. A coding section produces a coded password XW2 by coding a password PW2 input by the user using the coding algorithm, and a checking section compares the coded passwords XW1 and XW2. An access control section permits access to the recording medium when the checking section judges that the passwords XW1 and XW2 match, while barring access when the passwords XW1 and XW2 do not match.
