| 20120134493 | CRYPTOGRAPHY BY PARAMETERIZING ON ELLIPTIC CURVE - A device is controlled by a controller on the basis of a password. A determination is made at the device or at the controller, on the basis of a random value r | 05-31-2012 |
| 20120131051 | METHOD FOR SEARCHING FOR AN ENTITY USING A VERIFIER DEVICE, AND RELATED DEVICES - In a method for searching for an entity belonging to a set of entities, a verifier device and the entities are arranged so as to exchange information via at least one communication channel. Each entity has a first respective identifier from which a plurality of representatives can be obtained. According to the method, a first identification word (m | 05-24-2012 |
| 20120093309 | CRYPTOGRAPHY ON A SIMPLIFIED ELLIPTICAL CURVE - A cryptographic calculation includes obtaining a point P(X,Y) from a parameter t on an elliptical curve Y | 04-19-2012 |
| 20120087555 | IMAGING DEVICE HAVING A PRISMATIC ELEMENT - An imaging device includes a transparent prismatic element having two contiguous inlet surfaces separated by a ridge. A lens and an image sensor make it possible to acquire images, each including a reproduction of a first pattern located against one of the inlet surfaces, and a reproduction of a second imaged pattern through the other inlet surface. Such a device can be used in a biometric detection apparatus for detecting both a skin print and the vein distribution of a user. The device can also be used in a reading terminal capable of detecting a skin print and a machine-readable tape. | 04-12-2012 |
| 20120084849 | DEVICE AND METHOD FOR SECURE ACCESS TO A REMOTE SERVER - The device and method described herein relates to the field of computer security and, specifically, to the field of protecting confidential personal information which enables encrypted access to the remote server. A device and a method for securing confidential user information and secure exchanges of such information with the servers that host the services is provided. The device and method are based on personalising a smartcard containing the information. The chip card, connected to the user terminal, has a connection enabling the terminal to appear as a standalone host of the user's local network. An encrypted connection is then established directly between the chip card and the server hosting the service for the transmission of confidential data. The data, stored on the chip card, are then exchanged with the server via the encrypted connection. The data are never accessible in plain text on the user terminal. | 04-05-2012 |
| 20120082307 | CRYPTOGRAPHY ON A ELLIPTICAL CURVE - A cryptographic calculation includes obtaining a point P(X,Y) from a parameter t on an elliptical curve Y | 04-05-2012 |
| 20110274269 | ENCODING POINTS OF AN ELLIPTIC CURVE - The method comprises, in an electronic component, carrying out a cryptographic calculation that includes the step of obtaining points P on an elliptic curve following the equation Y | 11-10-2011 |
| 20110231667 | Method of Identification or Authorization, and Associated System and Secure Module - Method of identification or of authorization using a system comprising at least one sensor for acquiring biometric data and one secure module storing a set of digital data obtained starting from a set of respective biometric data by means of a digitization algorithm. According to this method, a biometric data value is obtained, acquired by the sensor; a digital value is obtained by application of the digitization algorithm to the acquired biometric data value; within the secure module, at least some of the digital data from said set of digital data are ranked according to their proximity to the digital value obtained; and a biometric data value is obtained from said set of biometric data by taking into account a position of the corresponding digital data within the ranking. | 09-22-2011 |
| 20100310070 | Generation and Use of a Biometric Key - In a control system comprising control device adapted for, on the one hand, receiving signal indicating a first biometric datum (W), and, on the other hand, obtaining a second biometric datum captured (w′), at the level of the control device, the first and second biometric date are compared. Next, it is decided whether the first and second biometric data correspond on the basis of the comparison. Thereafter, at least a secret cryptographic key part (H(w)) is generated by applying cryptographic function to the first biometric datum. | 12-09-2010 |
| 20100284538 | Control of an Entity to be Controlled by a Control Entity - A control entity communicates with an entity to be controlled so as to effect a control, a secret key being associated with the control entity. These entities share public parameters, a second public parameter being a combination of a first public parameter of the said plurality with the secret key. At the level of the entity to be controlled, a random value is generated, a first message is transmitted to the control entity, this first message comprising at least one value obtained by combining the first public parameter with the random value; and a second message is transmitted to the control entity, this second message comprising at least one value obtained by combining the first random value, a secret key of the entity to be controlled and a value received from the control entity. One of the values included in the first or the second message is based on the second public parameter. | 11-11-2010 |
| 20100281269 | Identification Based on Encrypted Biometric Data - A database comprising biometric data stored in encrypted form is managed by a management unit. It comprises a set of filters respectively associated with filter identifiers. A biometric data item is received at a management unit; next, said biometric data item is stored in an encrypted form at a given address in the database. Then keywords are obtained on the basis of a first set of hash functions and of the biometric data item. A subset of indexing filters is associated with each keyword by selecting, for each keyword, filters as a function of the respectively associated filter identifiers, of said keywords, and of a second set of hash functions; and the given address is associated with each of the filters of the subset of filters. | 11-04-2010 |
