    Abstract: Torsional vibration damper (1;20;30;40;50) which is suitable for dampenin g the motion of a rotatable element, said torsional vibration damper compris ing an "actuation" element (3) which is connectable to the rotatable element , an "inertia" element (5) arranged co-axially and rotatably with said actua tion element, an enclosed volume (8) between said inertia element and said a ctuation element where a cross section through said enclosed volume taken on a plane which is parallel to the axis of the actuation element comprises at least one "axial" portion (11 ) which is arranged essentially parallel to t he axis of the actuation element, an Electro-Rheological or a Magneto-Rheolo gical fluid (9) arranged at least in a part of said enclosed volume, and an electric or a magnetic field generator (7) in the form of a coil which gener ates an electric or a magnetic field which passes through at least a portion of said enclosed volume. The field generator is integrated into the torsion al vibration damper in such a way that a majority of the magnetic or electri c field lines (12) generated by the field generator pass through said "axial " portion of said enclosed volume. In this way, an effective torsional vibra tion damper is provided.

    Abstract: There is provided an encryption device including a data encryption unit configured to conduct encryption on the basis of a white box model in which at least a part of a plurality of round functions for sequentially conducting encryption processing on an input value is tabulated, and input and output values of the round function are recognizable from an outside. The plurality of round functions each have an encryption function that is tabulated and encrypts an input value in a black box model in which input and output values are recognizable from the outside and an intermediate value is not recognizable from the outside.
