Abstract (en)

[origin: WO2006133934A1] The invention relates to a method for operating a portable data carrier (1). According to the method, a number of files (11) having an encrypted data content are stored in a memory (4) of the portable data carrier (1). The data contents of the different files (11) are encrypted in a different manner so that a file-specific key is required each time for a decryption. In order to access the data content of one of the files (11), the appurtenant file-specific key is presented to a process running in the portable data carrier (1).
