摘要

The invention relates to an apparatus and a method for rendering user data. In order to provide a higher level of protection against hacking of data during transport within a PC, a method is proposed according to the present invention comprising the steps of: -receiving encrypted user data and key data by a drive unit ( 2 ), -decrypting said user data using said key data, -re-encrypting said decrypted user data using a re-encryption key, -transmitting said re-encrypted user data and said re-encryption key from said drive unit ( 2 ) to an application unit ( 3 ), -decrypting said re-encrypted user data using said re-encryption key, -reproducing said decrypted user data into application data, -re-encrypting said application data, -transmitting said re-encrypted application data from said application unit ( 3 ) to said drive unit ( 2 ), -decrypting encrypted application data, -transmitting said decrypted application data from said drive unit ( 2 ) to a render unit ( 4 ), and -rendering said application data.
