Abstract:
The present invention concerns a personal token for a mobile terminal in a communication network including an authentication server and a secure server producing derived key material on the basis of a random and a secret key (K) for use in an authentification and key agreement (AKA) procedure in a third-generation mobile system, said personal token including program instructions for re-computing the derived key material (Ck, Ik) on the basis of the received random and the secret key (K) as stored in the personal token, characterized in that the personal token includes program instructions for using a re-computed part of the derived key material in order to interpret the received additional data. This modification of the standard AKA procedure allows the personal token to keep the key material unavailable to the mobile terminal.

Abstract:
For protecting a circuit (1) against a mechanical or electromagnetic attack, an active protection device attached to the circuit comprises: - at least one generator (13, 14) for generating a magnetic field, - at least one magnetic sensor S1, S2, S3, S4 for measuring a value of the magnetic field, - an integrity circuit connected to the at least one magnetic sensor S1, S2, S3, S4 and to the circuit (1). The integrity circuit activates a reaction procedure in the circuit if the measured value of the magnetic field made by the magnetic sensor is out of a values domain, the values domain being correlated to the generated magnetic field.
Abstract:
The chip card module, when in an intermediate condition, comprises: a double-sided dielectric layer (10) with conductive patterns formed on both sides; a chip (12) supported on the backside (14) of said dielectric layer; first contact pads (20) arranged on the frontside (16) of said dielectric layer; and second contact pads (24) arranged on the backside (14) of said dielectric layer. The chip (12) and first (20) and second (24) contact pads are located within a peripheral cutout line (22) adapted to define the outer shape of the module in a further manufacturing condition after punching the dielectric layer along said line. A plurality of via holes (30) are formed through the dielectric layer at respective hole locations arranged beyond the cutout line, along with corresponding test pads (26) each formed on the frontside (16) so as to extend over a respective via hole and connected to a respective first contact pad (20). This enables simultaneous electrical access from the backside (14), in particular for test probes (32, 34), both i) directly to the second contact pads (24) and ii) indirectly to the first contact pads (20) by way of the test pads (26) being accessed at the bottom of the via holes (30).
Abstract:
The chip card comprises a card body (24) and an embedded chip module (14) having a plurality of contact fields (C1-C8) connected to respective terminals of the chip. The card body further comprises a positioning feature (28) adapted to univocally identify said contact fields according to their location and orientation on the card body. The positioning feature is a hole or a notch formed on the card body in an area including the chip module such as a contact field (C1-C8) which has no electrical functionality as contact field C6 according to ISO 7816-2. The invention is particularly adapted to card bodies including a plug-in removable portion of smaller size comprising said chip module and said positioning feature such as smaller size "mini-plug" SIMs for mobile phones.
Abstract:
A smart card is provided in which addresses of data are hidden. The smart card comprises a microcontroller (10), a memory (12) and a data bus (14) for the transmission of data therebetween. Memory address is hidden by use of a bus interface (18) provided at each of the microcontroller (10) and the memory (12) which performs a scrambling/unscrambling function on the address.
Abstract:
End-to-end communication between a UICC and a remote node on a network without requiring implementation of special purpose protocols at the remote node. The UICC operates to transmit a command using a first protocol from the UICC to the terminal to request the terminal to open a data channel to the network. The wireless terminal operates to, in response to the request to open a data channel, attempt to open a channel to the network. Upon indication that a data channel has successfully been opened: the UICC operates to transmit datagrams of a second protocol to the wireless terminal using the first protocol. The wireless terminal operates to receive the datagrams from the UICC and to transmit the datagrams received from the UICC to the network using the second protocol. The wireless terminal operates to receive datagrams of the second protocol from the remote entity and to transmit the datagrams from the remote entity to the UICC using the first protocol.
Abstract:
A method for downloading services to a first mobile terminal, wherein each ser-vice has a format corresponding to a type of a respective mobile terminal, and wherein said service is being stored in a first terminal irrespective of the format corresponding to the type of said first terminal, comprises a converting step to convert the service from a first format into a second format, and a sending step of effecting sending the from the first mobile terminal to a mobile terminal.
Abstract:
The invention relates to a system comprising a reader (20) and a contactless integrated circuit intended to be connected to an antenna to be incorporated, together with the integrated circuit, in a portable object body, and a method for communicating with such an integrated circuit. The invention is characterised in that the integrated circuit and the reader are electrically connected through conductive lines (25, 26) so that said reader and said integrated circuit are able to communicate according to a contactless communication protocol, without antennas. The invention specifically applies to contactless cards.
