Abstract:
The invention relates to a personal token (15) for access to a telecommunication network, such as a SIM card, said personal token (15) storing an entity which is able to deliver to a rendering device (10) associated with said token a rights objects, said rights object comprising at least a decryption key and at least a usage right for the digital content
Abstract:
Providing application programs the right to access a data item while preventing security breaches, allowing applications and data to be independently updated, and allowing multiple applications to share the data item. Each application program has associated therewith a first public key and each data file has associated therewith a second public key. If these public keys match for a particular application program and data file, the application program is granted access to the data file.
Abstract:
The invention relates to a personal token (10) for authentication in a network comprising a piece of software for initiating an SSL connection by generating a message authenticating said token to a remote server (30) characterized in that the piece of software controls the processing of the message so as to use of a data (12) which is prestored in the token (10) and which is specifically associated with the remote server (30) so that the message can be interpreted only by the specific remote server (30).
Abstract:
The invention concerns a portable device for at least one-way communication with a terminal, comprising a micro-module including a chip, and further comprising an antenna enabling communication between the micro-module and a terminal provided the antenna is placed immediately proximate the terminal. Said device is characterized in that it comprises reproducing means removably receiving the micro-module, said antenna being supported by said reproducing means such that the micro-module is removable relative to the antenna.
Abstract:
For an application running on a smart card, a user interface to be displayed on a terminal device provided. Hypertext pages are dynamically created by the applica-tion running on the smart card and served to a browser running on the terminal device.
Abstract:
The invention relates to a document comprising a cover (1), at least one internal page (2-1, 2-2, 2-3), a radiofrequency microcontroller (3) and an antenna (4) electrically connected to contact pads of said microcontroller (3). The invention is characterised in that said document further comprises an electromagnetic shield (6) capable of disrupting, at least partially, the wireless communication with said microcontroller when the document is closed. The invention applies, in particular, to an electronic passport.
Abstract:
The invention relates to secured identification documents and method for making them. The problem to be solved by the invention is to develop a secured identification document, comprising at least two flexible layers (32-37) embedding an electronic module (21), said electronic module including a flexible substrate (30) on which are positioned an antenna and a radiofrequency microcontroller storing identification data, said microcontroller being electrically connected to said antenna, said identification document being physically resistant against all type of attacks, in order to avoid a fraudulent person pulling out the module from the identification document by delamination of the constitution layers. The solution to this problem is achieved by the fact that the electronic module is strongly embedded and made interdependent with the stack of said at least two layers (32-37) by means of a chemically and mechanically tamper proof material .
Abstract:
La présente invention concerne un procédé de protection d’un ensemble mettant en œuvre un processus de calcul cryptographique qui utilise une fonction homographique f du type : - f(z)= (az+b) / (cz+d) n’est pas égal à 0 et - f(-d/c)=a/c la fonction f opérant sur des variables masquées caractérisé en ce que, pour tout k, si x est une entrée et y = f(x+k) une sortie de la fonction f, pour passer directement d’une valeur masquée x+m_i (masquage additif de type XOR) à une valeur masquée y+m_j, le procédé consiste à réaliser cette opération à l’aide d’une composition de plusieurs transformations opérant sur GF(2^k) avec l’adjonction de l’infini, définies sous forme (ax+b)/(cx+d), et de transformations qui échangent deux points.
