摘要： Exemplary methods are provided for storing data in a flash storage device to facilitate subsequent detection of tampering, comprising receiving a plaintext; reading first metadata associated with a device sector; encrypting the plaintext based on the first metadata to generate a cipher text and first authentication data; storing the cipher text in the sector; and storing the first authentication data as second metadata associated with the sector. 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. Memory devices embodying said methods are also provided.
