摘要

The system has a central processing unit (9) comprises a case (1) and a casing sensor (5) integrally mounted in the case. The sensor supplies movement signals representative of any changing of position in a space of the case. An alarm module (2) controls transmission of alarm signals if the system is activated and a non nominal signal, representative of unauthorized changing of position in the space of the case, is supplied by the sensor. Independent claims are also included for the following: (1) a central processing unit comprising a case (2) a method for self-protecting the central processing unit.
