Techniques for protecting digital content in a storage device from pirate and illegal use are described. According to one aspect of the techniques, a method for protecting digital content stored in a storage device from illegally accessing by a host, comprises: exchanging data between the storage device and the host to achieve a mutual authentication between the storage device and the host; disabling an encryption/decryption module in the storage device to prohibit the host from reading out the digital content decrypted by the encryption/decryption module until the authentication of the storage device to the host passes; and disabling the host to prohibit the host from reading out the digital content decrypted by the encryption/decryption module if the authentication of the host to the storage device fails. Thereby, pirate and illegal use of the digital content stored in the storage device are effectively prevented or decreased. |
