<p>The invention relates to an electronically tested high-security coder/decoder device, comprising a key ( 1 ) consisting of a mechanically produced code, a body with integrated interpretation and actuation unit ( 2 ) and an electronic processing device ( 3 ) connected thereto. The key ( 1 ) has at least one pressure generator and pressure sensor unit ( 12 ) with code producing pressure elements ( 121, 122, 12 n) and with one pressure transmitting part each. The interpretation and actuation unit ( 2 ) is provided with a unit ( 22 ) that converts pressure values known as such to electrical signals, an authorization unit ( 23 ) and an exe ( 24 ). The conversion unit ( 22 ) has an input ( 221 ) and an output ( 22 ). The output ( 22 ) is connected to the input ( 311 ) of the central processing unit ( 31 ). The central processing unit ( 31 ) and the interface ( 32 ) cooperate to give the electronic processing unit ( 3 ). The interface output ( 322 ) is connected to the input ( 232 ) of the authorization unit ( 23 ) whose output ( 231 ) is connected to the input ( 241 ) of the execution unit ( 24 ).</p> |
