Exemplary methods are also provided for detecting tampering with data stored in a flash storage device, comprising determining a physical location in a device sector; reading cipher text from the physical location; reading first authentication data and maintenance metadata associated with the sector; decrypting the cipher text based on a user key and the maintenance metadata to generate second authentication data; and determining the occurrence of tampering based on the first and second authentication data.
