A trusted computing environment 100, wherein each computing device 112 to 118 holds a policy specifying the degree to which it can trust the other devices in the environment 100. The aim of the invention is to disclose and to produce coated reshaped aluminum semi-finished products andor components which as semi-finished products can still be re-shaped and hardened at high temperatures. In the nano fiber reinforced composite, nano fibers are uniformly arranged between matrix components with no fibers formed therein, the nano fibers being arranged at an orientation angle of 90\xb0 or less relative to the longitudinal axis of the composite material. An oxide spacer is formed along sidewalls of the stacked structure. The front and top shields have arcuate panels that, in combination with the rotation around the base, provide for an enclosure around an appliance. The invention also relates to a system for implementing the method, comprising an imaging device that can be installed in the vicinity of the area of the structure to be inspected, and an image-processing device located remotely from the imaging device in order to generate a 3D image from the images captured by the camera.
