| 20120107252 | METHOD FOR FORMING CYCLODEXTRIN POLYMER AND LIPOPHILIC COMPOUND EMULSIONS, RESULTING EMULSIONS, AND COMPOSITIONS INCLUDING SAID EMULSIONS - The present invention relates to a method for preparing a cyclodextrin polymer and/or a hydrophilic polymer emulsion having cyclodextrins as well as lipophilic compounds, the emulsions having a remarkable stability. In particular, the method includes: (i) adding a lipophilic compound into an aqueous solution of a cyclodextrin unit polymer or hydrophilic polymer having cyclodextrins; (ii) forming an emulsion from the mixture resulting from step (i). The invention also relates to the resulting emulsions, i.e. stabilized emulsions by a non-covalent and non-crystalline inclusion complex consisting of (i) a cyclodextrin unit polymer or a hydrophilic polymer having cyclodextrins and (ii) a lipophilic compound. The invention also relates to the use of said emulsions in the cosmetic, pharmaceutical and/or agri-food fields. | 05-03-2012 |

| 20100239091 | METHOD FOR GENERATING MASKS IN A COMMUNICATING OBJECT AND CORRESPONDING COMMUNICATING OBJECT - The invention relates to a method for generating masks in a communicating object, the masks being intended to mask data to be stored in the communicating object. At least one master mask is stored in the communicating object. According to the invention, the method involves applying at least one diversifier to the master mask so as to generate a diversified mask; masking the datum to be stored in the communicating object by a reversible function using the diversified mask, the mask generating a masked datum; and storing the masked datum in the communicating object with the diversifier used to generate the diversified mask for obtaining the masked datum. The invention also relates to a communicating object including components for implementing such a method. | 09-23-2010 |

| 20090217050 | SYSTEMS AND METHODS FOR OPTIMIZING SIGNATURE VERIFICATION TIME FOR A CRYPTOGRAPHIC CACHE - Embodiments provide systems and methods to optimize signature verification time for a cryptographic cache. Time is reduced by eliminating at least some of the duplicative application of cryptographic primitives. In some embodiments, systems and methods for signature verification comprise obtaining a signature which was previously generated using an asymmetrical cryptographic scheme, and determining whether an identical signature has previously been stored in a signature cache. If an identical signature has been previously stored in the signature cache, retrieving previously generated results corresponding to the previously stored identical signature, the results a consequence of application of cryptographic primitives of the asymmetrical cryptographic scheme corresponding to the identical signature. The results are forwarded to a signature verifier. In at least some embodiments, at least one of these functions occurs in a secure execution environment. | 08-27-2009 |
| 20090282264 | ENCRYPTION/DECRYPTION ENGINE WITH SECURE MODES FOR KEY DECRYPTION AND KEY DERIVATION - In at least some embodiments, an electronic device comprises a processor and an encryption/decryption (E/D) engine coupled to the processor via a bus. The E/D engine selectively operates in a first mode and a second mode. For the first mode, an E/D engine output is provided to the bus. For the second mode, the E/D engine output is not provided to the bus and is accessible only to the E/D engine. | 11-12-2009 |

| 20090097555 | Video encoding method and device - Successive images (F) of a video sequence are encoded in order in generate parameters which are included in an output flow (F) that is to be transmitted to a decoder. The encoding of certain images is effected in Inter mode relative to one or several previous images of the sequence. The output flow also includes long term marking commands for certain images and demarking commands for previously marked images. Each long-term marked image is kept in a memory by the decoder until a corresponding demarking command is received. Return information on the restoration of the images of the video sequence by the decoder is received by the encoder (1) and analyzed in order to identify an image that has been lost by the decoder. It is possible to encode a following image of the sequence in Inter mode in relation to a long-term marked image in response to identification of an image lost to the decoder. | 04-16-2009 |

| 20100017499 | Data downloading initiated by portable communicating objects during a campaign - Content data available in a server is downloaded to portable communicating objects via a radio communication network during a data downloading campaign initiated by a portable communicating object upon transmission of a request of content availability to the server when at least one request transmission triggering element fulfills a rule stored in the portable communicating object. Upon reception of the content availability request, one of the devices including the server and the portable communicating object determines whether the content data are available for the portable communicating object so as to transmit the same thereto. | 01-21-2010 |

| 20090307358 | Transmission of Data Between A Server and A Communicating Object - Transmission of data between a download server and a communicating object through a communications network is initiated by a registration server, by transmitting connection parameters received from the download server to the communicating object via a first data channel opened by a first agent of the communicating object after attaching the object to the network. As a function of the connection parameters, a second agent in the communicating object opens a second data channel to the download server so as to transmit the data therein. As long as the first data channel is open, other servers can initiate a transmission via the registration server. | 12-10-2009 |
| 20100211784 | METHOD FOR ACCESSING A PORTABLE DEVICE, CORRESPONDING PORTABLE DEVICE, HOST DEVICE AND SYSTEM - The invention relates to a method for accessing a portable device, the portable device being connected to a host device. According to the invention, the host device, as a client, opens a communication channel to the portable device, as a server, according to a first network communication protocol, and the portable device, as a client, uses the communication channel to transport data to the host device, as a server, according to a second network communication protocol, without the implementation of any complex infrastructure. The invention relates also to a corresponding system for accessing a portable device, a corresponding portable device accessible from outside and a corresponding host device for accessing a portable device. | 08-19-2010 |
