Abstract
Provided is a cryptographic processing apparatus for a storage medium, including: a location information conversion unit that stores a conversion result in a buffer, the conversion result obtained by performing a conversion process on location information indicating a location of data to be accessed on the storage medium; and a data cryptographic processing unit that performs cryptography processing on the data using the conversion result stored in the buffer, the cryptography processing being one of encryption and decryption.
