Abstract: The invention relates to a method for securing the execution of a cryptographic algorithm A against fault attacks. Given a cryptographic key KO and a message M, the cryptographic algorithm A is set to compute a value A(KO,M). Given a relationship R between A(KO,M) and A(f(K0),g(M)), where f and g are two bijections, and where f is different from the identity function, the method comprises: a. computing the expected result A(KO,M) of the cryptographic algorithm b. computing a modified result A(f(K0),g(M)), by applying the cryptographic algorithm A on a modified key f(K0) and on a message g(M), c. checking whether the relationship R between the values A(KO,M) and A(f(K0),g(M)) computed in the two preceding steps is verified d. detecting an attack if the relationship R is not verified. The invention also relates to a cryptographic device embodying the above method.
Abstract: A method and system for providing authentication of a user to a first peripheral device connected to a host computer using an authentication of the user on a second peripheral device, thereby allowing the user access to both devices through a single authentication. A security function on the second peripheral device is used to create an authorization phrase. Subsequent accesses to the first peripheral device requires the second peripheral device to re-create the same authorization phrase thereby demonstrating that the same second peripheral device is being used to access the first peripheral device and that a user was successfully authenticated to the second peripheral device. Other systems and methods are disclosed.

Abstract: This invention relates to a method for the transmission using the half-duplex mode of a data signal from a first transmission/reception device to a second transmission/reception device, called the remote device, comprising a logical coding step in which at least two distinct transmission times are associated with two respective statuses of the data signal to transmit. The method is characterized in that it comprises the generation by the first device of a signal (10, 11) comprising, for the transmission of a status of the signal, more or less exclusively a plateau at a first voltage level for the time defined as the transmission time associated with the status to transmit and a falling edge, to the exclusion of any rising edge, the transmission of a data signal status from the second device to the first device comprising the generation of a signal (20, 21) by the second device comprising more or less exclusively a plateau at a second voltage level and a rising edge, to the exclusion of any falling edge.

Abstract: The invention concerns a method enabling a server manager to prove subsequently that the server was authorized to read a user's personal data in a terminal station (ST), comprising: transmitting server policy data (PS) to the station; comparing the server policy data with private policy data (PP) pre-stored in the station; determining a signature (SGST) of server policy data received in the station; and transmitting the signature with the personal data (DP) read in the station to the server when the compared policy data (PS, PP) are compatible.
Abstract: A method of detecting an abnormal environmental operating condition of an element embedded in an apparatus. The element is able to communicate with a telecommunications network. The method includes cyclically measuring at least one environmental operating parameter of the element, detecting that the element is operating for an excessive duration in at least one reference operating span, and transmitting an alert message to the telecommunications network if the element has operated for an excessive duration in the reference operating span.
Abstract: A data medium has at least first and second parts joined together, each having an outer face turned towards the outside and a hidden inner face. At least one of the first and second parts bears, at a certain distance from the outer faces, hidden markings corresponding to personalization data. This first part and preferably the second part of the medium are, at least locally, opaque with respect to through-transmission of laser radiation liable to modify the hidden markings.

Abstract: The invention relates to a method for loading a list of preferred networks into a secure element contained in a mobile terminal. The loading is accomplished when the secure element detects that it is in a roaming condition within a telecommunication network. The method consists of: i) asking (12) for an IP channel to be opened between the telecommunication network and the secure element, the request for opening originating with the secure element; ii) requesting (13) the loading of the list of preferred networks; iii) uploading (14) via the IP channel the list of preferred networks into the secure element; and iv) transmitting (16) a request by the secure element to the mobile terminal to use one of said preferred networks in said list.
Abstract: A system allows the display of a private file on a screen of a telecommunications terminal. This system includes a first and a second Internet site. In the first Internet site, a first image contains a coded link to an address of a file of the second Internet site. The private file is stored in encrypted form in the meta data of the file in the second Internet site. A program recognizes the coded link and searches the meta data of the file whose Internet address corresponds to the coded link for authorization of a person connected to the first Internet site to view the private file. The program downloads the private file of the second Internet site via a remote protocol from the telecommunications terminal if viewing is authorized, to display the private file on the screen.

Abstract: An electrochromic display module employing a unique combination of architecture and electrochromic composition to provide an extended life to the module. The architecture may involve the use of an extended seal about a perimeter of a display portion where the composition is located. In this manner, the rate of solvent leakage from the composition may be substantially reduced. Additionally, the electrochromic composition itself may make use of particular low volatility solvents and constituent combinations so as to discourage the amount particle generation therein. Ultimately, an electrochromic display module having a useful life of more than about 3 years may be provided.
