| 20120110336 | DATA VERIFICATION METHOD - (EN)An electronic system ( | 05-03-2012 |
| 20110162083 | SYSTEM AND METHOD FOR SECURING DATA - The invention relates to a system and method for making data secure. The inventive system is characterized in that it comprises:—a monotonic counter;—a computational entity;—a physical data medium comprising one or a plurality of data blocks, a first master block comprising the last value recovered from the monotonic counter, an identifier of the last data block written on said medium, a first authentication code guaranteeing the authenticity of the written data block or blocks, a second authentication code calculated from the last written data block, said data being fixed at a neutral value, and a third authentication code guaranteeing the authenticity of the first master block, and a second master block forming a replica of the first master block; and—an authentication key. The invention is used, in particular, to make data secure against playback and sudden interruptions in service in embedded systems. | 06-30-2011 |
| 20110131423 | SYSTEM AND METHOD FOR SECURING A USER INTERFACE - The invention relates to a method for securing a user interface that comprises a user interface including one or more peripheral hardware devices of the user interface for interaction with said interface, said peripheral hardware devices being driven by driver software, and one or more applications using the user interface. The invention also relates to a method for securing such an interface. The system of the invention is characterised in that the same further comprises a hypervisor and one or more virtual machines, the drivers of the peripheral hardware devices of the user interface being divided into two portions, i.e. a main portion of said drivers under the control of the hypervisor and a front-end portion of said drivers under the control of the virtual machines, wherein the front-end portion of the securing software component is in charge of managing the front-end portion of the drivers and the main portion of the securing software component is in charge of managing the main portion of the drivers. The invention can particularly be used in onboard systems. | 06-02-2011 |

| 20090282397 | Secure Dynamic Loading - The invention relates to a method for loading, installing and running software, called loading units, having different levels of confidence by a data processing unit ( | 11-12-2009 |
| 20080320315 | Method for Creating a Secure Counter on an On-Board Computer System Comprising a Chip Card - According to the inventive method, the chip card, a counting function (FC), a counter (Cpt) and a private key (Cf) stored in the write-only part of the memory region are stored in a persistent memory, the counter and the private key (Cf) being accessible only by the counting function (FC). When the chip card receives a counter request emitted by an requesting entity (ER), the counting function (FC) performs a modification of the counter (Cpt) and a calculation of a signature, and sends a response to the applicant entity (ER). When the on-board system receives the response to the counter request, the signature contained in the response is checked. | 12-25-2008 |
