Abstract
An external compact disc drive for data encryption and decryption and the method is disclosed. The back up data is encrypted, via an encryption key generated by an encryption/decryption unit of the external compact disc drive during the recording of back up data to a compact disc. The encrypted back up data is saved to a public area of the compact disc. An authentication key is generated via an authentication password set up by a user. The encryption key is encrypted via authentication key and saved to a private area of the compact disc. The authentication password and the authentication key are not recorded in the external compact disc drive or the compact disc. Thus, encryption key can only be retrieved with a correct authentication password via a compact disc drive having the encryption/decryption unit. Following that, the back up data can be decrypted and retrieved.
