摘要： A method for authenticating a user to a provider, among a plurality of providers. The method uses an authentication device comprising, for each of provider, a record comprising a pairing key and first data, both as shared data. Provider authentication data comprises a first cryptogram obtained by encrypting said first data with said pairing key. Authenticating provider authentication data is performed at the authentication device by the steps of decrypting said first cryptogram by means of the pairing key stored in one of said records, then comparing the result of this decryption with first data resulting from pairing data stored in said record, if the comparison does not indicate a match, then processing again the previous decryption and comparison steps by using the pairing key of another record until each of said records stored in the authentication device has been processed.

摘要： Method and system for personalizing a chip, intended to be integrated into a smart card, comprising a tester associated to an FPGA device connected to the chip, the chip being part of a wafer comprising a plurality of chips and a disposable hardware module for verifying presence of the chip on the wafer. The tester sends a first secret code to the FPGA device, which commands the chip to initiate a test mode activation. The FPGA device encrypts a second secret code by using a secret encryption algorithm parameterized with a random number received from the chip and the first secret code to obtain a first cryptogram which is sent to the chip. The chip determines a second cryptogram by carrying out a Boolean function over a result obtained by decryption of the first cryptogram using the inverse algorithm parameterized with the random number and the first secret code. The second cryptogram is compared with a result obtained by carrying out the Boolean function over the second secret code temporarily stored on the chip. The FPGA device personalizes the chip only if the second cryptogram matches the calculated result.

摘要： Authentication method of at least one application using resources stored in a security module associated to an equipment connected to a control server via a network. The control server receives via the network, analyzes and verifies identification data comprising at least an identifier of the equipment and an identifier of the security module, generates a cryptogram comprising a digest of the application, the identification data and instructions intended for the security module and transmits the cryptogram, via the network and the equipment, to the security module. The latter verifies the application by comparing the digest extracted from the cryptogram with a calculated digest, wherein, during at least one of initialization and activation of the application, the security module executes the instructions extracted from the cryptogram and either releases or blocks access to certain resources of said security module according to a result of the verification of the application.

摘要： The present invention provides a method for secure communication of digital information between a transmission entity and at least one reception entity. The method may be applied in the domain of audio/video data transmission, where stuffing data packets comprising random payloads are inserted into a transport stream along with true data packets comprising the audio/video data. The dummy data packets are detectable by an authorized reception entity but not detectable by unauthorized reception entities. A large number of stuffing data packets are included in the transmission to occupy bandwidth and to further render the job difficult for an unauthorized reception entity which tries to intercept the transmission.

摘要： A system and method give a user control of personal data. A trusted center comprises a database for personal data, access conditions for the personal data, and a counter. A user loads personal data into the database and assigns access conditions to said data. The personal data is divided into at least two categories, each associated with a user's value. A third party requests access to personal data of a plurality of users, the request comprising search criteria. The trusted center identifies a first set of users matching the search criteria and returns the quantity of users in, and a sum of user's values for, the first set. The third party acknowledges all or part of the sum, and the trusted center returns the personal data of a second set of users for which the sum covers the user's values and updates the counters of user in the second set.

摘要： A method is described for rewarding a viewer of a broadcast program in exchange for the viewer proving his presence at the time that certain program content is being broadcast. The method involves the use of running an application in a television environment, said application displaying a graphic inviting the viewer to intervene in some manner and to subsequently log the viewer's intervention, thereby documenting his viewing activity. The method further allows for the convenient and mobile reporting of the status of a log of the viewer's viewing activity. Finally, the method allows for the convenient and flexible redemption of accrued credit, as documented in the viewing log, against goods and/or services.
