  • Authentification of data in a digital transmission system
    Patent number: 7760986
    Abstract: A method of authentification of data sent in a digital transmission characterized by the organization and authentification of the data prior to transmission into a hierarchy of at least one root directory unit (75), subdirectory unit (76) and file unit (77), data in a file (77) being acted upon by an authentification algorithm and an associated file authentification value (82) stored in the referring subdirectory unit (77), this file authentification value (82) being in turn acted upon by an authentification algorithm and an associated subdirectory authentification value (79) stored in the referring root directory. Other aspects of the invention relate to the authentification of a second root directory (78) by generation of a second authentification value (83) and the authentification of data before encapsulation in tables or sections of a transport stream.
