Vorrichtung und Verfahren zum Verschlüsseln von Daten

摘要

The device has an encrypted data decrypting unit that decrypts the encrypted data by using a decryption algorithm and a decryption key. The decryption key corresponds to an encryption key, and an auxiliary key calculation unit calculates the auxiliary key. A decrypted data encryption unit encrypts the decrypted data using the encryption algorithm and the auxiliary key, in order to obtain an output data. - Independent claims are also included for the following: - (a) a method for encrypting the base-line data - (b) a computer program having a program code that performs a method for encrypting the base-line data.
