<p>The method involves storing (E4') a root key (MSK) and a unique identification data (IDi) e.g. unique serial number, of an electronic device i.e. integrated circuit (10i), in a non-volatile memory of the device, before authenticating access to the device. A personal authentication key (MSKDi) is generated (E61') within the device in response to an analog signal or a digital signal e.g. control statement, received by the device, by diversifying the root key from the identification data. An access device is authenticated (E13') to access the electronic device by using the authentication key. Independent claims are also included for the following: (1) a method for producing electronic devices such as integrated circuits (2) an integrated circuit type electronic device comprising an authentication module (3) a system for producing electronic devices such as integrated circuits.</p> |
