A first device generates a first signature by using complete transaction data received from a second device, a first algorithm and a first key, modifies at least one character from the complete transaction data and gets partial transaction data, and sends to the second device the partial transaction data. The second device requests a user to modify the partial transaction data by providing at least one character, as complementary data to the partial transaction data, gets, as request response from a user, at least one character to modify the partial transaction data, a corresponding result being proposed modified transaction data, generates a second signature by using the proposed modified transaction data, the first algorithm and the first key, and sends to the first device the second signature. Only if the second signature does match the first signature, then the first device authorizes to carry out a corresponding transaction.

The invention relates to a method for manufacturing a USB electronic key, whereby a chip is cut out of a tape, provided with a plurality of chips, each chip defining contact pads in USB format and supporting an electronic component, connected to the pads. The thickness adjustment step is directly carried out on the chip to give a thickness conforming to the USB standard, at least in the area of the contact pads.

Method for manufacturing an electronic key with USB connector

A method for producing a portable electronic object having contact pads arranged on a plane with a thickness which differs from the thickness of a standard smartcard. The object is electrically connected to data transfer station connectors, by delivering a data transfer station having an electric probe connector and submitting the object to the data transfer station in such a way that the contact pads thereof are accessible to the electric probes in a direction perpendicular to the plane. Objects obtainable include UBS keys or PCMCIA cards or readers.

The invention concerns a USB-key type electronic device () comprising an electronic circuit mounted on a support (), a gripping element showing a graphic print and/or customization (p), a protective case () arranged at the element so as to cause the graphic print and/or customization to be visible through the case. The invention is characterized in that the graphic print and/or customization is produced on the support () bearing the electronic circuit, and in that the case covers directly said support (). The invention also concerns a method including the following steps: producing an electronic circuit support in the form of a printed smart card with contacts in conformity with the USB standard, producing a graphic customization on a support surface, protecting said graphic customization with a transparent protective shell.

Smart card readers dedicated to a particular application use both a microcontroller whose read only memory determines the running of the application, and a security component executing, under the control of the microcontroller, subroutines related to the security of the application (authentication, confidential programs, etc.). So that the manager of the application can have access to certain memory areas of the security component, provision is made for the microcontroller to be able to pass automatically to a so-called &ldquo;transparent&rdquo; mode, when a specific access code issued by a test card is recognized. In this mode, the read or write instructions for a memory area, issued by the test card, are interpreted by the microcontroller as being read or write instructions for a memory area of the security component rather than the microcontroller.
